Barn owls hunt in wet grassy meadows, old farm fields, tallgrass prairie and veg- etated ditches. From both a conservation and pest control standpoint, barn owls are a valuable component of the rural landscape. A family of eight barn owls can consume over 1,000 mice, voles and shrews in just one breeding season (Ingels, 1992). Homestead Areas

Rare in Ontario, the eastern population of the barn owl has been formally recognized as Endangered. In 1997, when barn owl numbers were very low, a group of inter- ested people in Haldimand-Norfolk initiated the Ontario Barn Owl Recovery Project. One of the components of this project is to erect nesting boxes on farms that have suit- able habitat for the bird, such as old fields, wetlands, barns and silos. Nesting boxes have been installed on dozens of farms along the north shore of Lake Erie with the hope of encouraging the barn owl’s recovery.

Cedar Waxwing Bombycilla cedrorum 12 Cedar are common summer residents and can be easily attracted to your homestead by native -producing trees and shrubs. They breed late in the spring, a habit which ensures that berry crops are ready when nestlings need to be fed in the later summer. Cedar waxwings have a remarkable ability to digest near- ly any type of berry, including ones that are poisonous to humans. They will even consume fermented , a practice which causes them to show definite signs of tipsiness!

Rarely seen alone, these handsome birds move erratically among food crops, feeding on berries in large flocks. Cedar waxwings in a flock tend to cooperate. When one bird has had its fill of berries, it will pass berries on to its neighbour, who will eat the berry or con- tinue to pass it along in a sort of berry bucket brigade, until a hun- Homestead Areas gry bird snatches it up. Listen for the faint, high pitched ‘tsee’ calls of cedar waxwings throughout the summer.

Cedar waxwings are sleek, crested birds with a black mask and a yellow band on the tip of the tail. A little smaller than a robin, these birds frequent open, wooded areas as well as parks, gardens and overgrown fields.

Careful Pesticide Use Is Important Conservation Tillage

Enhancing wildlife habitat also means that when pesticides are used, they must be carefully selected and applied. Informed decisions are needed to balance weed and pest control in crop production with the possible risks to wildlife and wildlife habitat. Insecticides may have a direct toxic effect on some birds, particularly ducks, and both insecti- cides and herbicides can harm wildlife food sources (AAFC, 1996). Many pesticide labels note toxicity to wildlife. Careful pesticide selection and application in strict accor- dance with label directions will ensure maximum wildlife benefits from your conservation tillage system.

Also remember that wells are affected by what is put on fields. Some herbicides such as 2,4-D remain for a long time in ground water and have been linked to increased health risks among farm workers.

Voracious Visitors

Throughout this guide book, the advantages of attracting birds to the farm have been emphasized. There are, however, some situations where farmers are finding it difficult to co- exist with birds. Depending on the type of farm operation, location and 16 the populations of certain species, birds which feed on fruit and other crops are a growing concern for pro- ducers in Ontario. Resident Canada Geese

Due to the widespread hunting of local game for food and sport in the 18th and 19th centuries, the Canada goose had virtually disappeared from nearly all of its for- mer breeding range in southern Ontario. In the 1960s, the Ministry of Natural Resources and some local groups re- introduced the Canada goose to southern Ontario. Since that time, goose numbers have not only rebounded, but in many cases are increasing exponentially due to suitable Conservation Tillage habitat and low predator numbers in the province. The Canadian Wildlife Service estimates that there are more than 400,000 resident Canada geese that breed and live in southern Ontario year-round (OSCIA, 2002).

Until recently, the familiar honking V-shaped formations of Canada geese were welcomed by farmers. For farmers working hard to make a living from their crops, however, large numbers of resident geese and goslings grazing on emergent crops are not a welcome sight. The expanding goose population is causing significant crop damage in some agricultural areas (OSCIA, 2002).

Management Options

Canada Geese are protected under the Migratory Birds Convention Act, which requires a permit for hunting within open seasons. Where geese are causing serious crop damage, several options exist to control them (CWS, 1997).

Modify breeding habitat Breeding females look for open areas with clear visibility, low predator numbers and nearby water. Create natural barriers of brush and shrubs around water areas to dis- courage geese from selecting a breeding site on the farm. Focus efforts on the habitat between open cropland and wetlands. This will also create habitat for songbirds such as the common yellowthroat. 17 Use scare techniques As soon as geese arrive, use sirens, strobe lights, propane cannons and bird-call distress tapes to scare birds away and encourage them to nest elsewhere. Vary the patterns of sounds or lights. Implementing a combination of scare tactics works best.

Erect barriers

Conservation Tillage To deter geese from entering cropland for food, place strands of ‘Bird Scare Flash Tape’ or other shiny, fluttery materials at goose and gosling height levels between waterways and crops. Although adult geese could fly over these barriers, they will not leave their flightless goslings.

Contact the Canadian Wildlife Service The Canadian Wildlife Service as well as Ducks Unlimited Canada and the Ontario Soil and Crop Improvement Association have been involved in researching various control methods to prevent severe crop damage. Permits are required to hunt or scare geese with a firearm or to attempt other more invasive control methods and may be obtained from the Canadian Wildlife Service.

18 Vesper Sparrow Pooecetes gramineus

The vesper sparrow is a bird little known to most casual observers. Its rich, musical song, which begins with two sets of unforgettable, double notes, ‘here-here! there-there!’, is commonly heard on rolling farmlands in Ontario. It is absent, however, from intensively farmed areas. The vesper sparrow favours ‘messy’ crops, showing a clear preference for foraging in fields with lots of crop residue (Rodenhouse & Best, 1994). The abundance of insects in conserva- Conservation Tillage tion tillage fields attracts these birds, which eat insects throughout the breeding season and switch to seeds for the rest of the year.

Vesper sparrows are found on the ground in well-drained or dry areas. During the springtime, males will hop onto a perch or a high tree branch to sing. The white outer tail feathers of the vesper sparrow are a distinctive mark when this little grayish, streaked bird takes off in flight from farm fields. Other distinguish- ing marks include a narrow white eye ring and a small patch of chestnut on the bend of its wing.

Vesper sparrow nests hold four to six white eggs that are heavily spotted with brown. The nest itself is a loosely-woven grass and rootlet cup, concealed on the ground in grass.

Northern Bobwhite Colinus viginianus

Difficult to glimpse amongst dense, tangled vegetation, the north- ern bobwhite can be identified by its unmistakable whistle, singing a rising ‘bob, bob-white’ throughout the spring. The patterned facial markings of the bobwhite set it apart in the field: these pat- terns are black and white in males and buff and white in females.

The northern bobwhite is the only native quail in eastern North America. In Ontario, it only survives in southwestern reaches of the province where winters are less severe. This species needs grass- 21 land for breeding, woody or brushy cover for shelter, and cropland for forage, all in close proximity. As a result, farmers using conser- vation tillage, strip cropping and cover crops can provide important food and habitat diversity for the bobwhite. In a North Carolina study, researchers found that bobwhite chicks met their daily nutrition- al requirements in less than six hours of foraging in no-till soybeans planted with wheat, compared to more than twenty hours of foraging in tilled soybean fields (Palmer and Lane, 1999). Vitamin A is a particu- Other Cropland Techniques lar requirement of this species, hence cover crops such as clover and grass are critical resources for this bird throughout the winter.

Northern bobwhite nests hold 10 to 15 eggs in a grass-lined hollow concealed in weeds or grass near open or cultivated land. Outside the breeding season, bobwhites gather in coveys of approximately two dozen birds, huddling together in the cold and vigorously defending their territory.

The range of northern bobwhites in Ontario dropped following a series of severe winters in the 1970s, and numbers remain low. Intensive farming methods that tend to limit on-farm diversity have reduced habitat quantity and quality for this species. Given the small, localized populations of this species and the threats to its habitat, the northern bobwhite is now listed as Endangered in Ontario. Consider implementing some of the techniques mentioned in this book to help this species recover.

22 est and weed management is an essential component of food production. Farmers must contend with European corn P borers, Colorado potato , alfalfa weevils, rusts, aphids, mites and many, many other pests in order to produce the food that people need. Conventionally, these pests have been coun- tered with synthetic pesticides, including insecticides, herbicides and fungicides.

25 Birds Can Help Prevent Your Pest Problems

Increasing habitat for birds by putting into practice the techniques mentioned in this guide book can benefit your pest management systems, and ultimately your crop yields.

Birds eat insect pests in vast quantities and provide other

Pest Management and Organics important services. In many cases, as noted below, farm- ers are reaping the benefits.

• Eastern bluebirds and swallows can control flies in pastures and other grazing areas, reducing the inci- dence of pink eye in livestock. • Bluebirds and swallows are also welcome participants in the biological control of insects on cherry farms (Brenner, 1991). • American kestrels, great crested flycatchers and other insect-eating birds can help control crop losses by insects such as grasshoppers, weevils and aphids (Ingels, 1992). • Red-tailed hawks, northern harriers, short- and long- eared owls and great horned owls are important rodent controllers. These birds of prey can help con- trol moles and mice, reducing silage and crop losses (Ingels, 1992). • Vesper sparrows forage extensively in fields for grasshop- pers, beetles and cutworms, while migratory songbirds consume enormous numbers of insects in farm woodlots and hedgerows (Rodenhouse & Best, 1994.).

Take a walk through these areas and you may see grassland birds, which are those that require open, grassy areas during the breed- ing season. The loggerhead shrike and Henslow’s spar- row, both listed as Endangered in Canada, depend on grassland areas for their survival. Songbirds such as the field sparrow, sparrow, eastern mead- owlark and bobolink build nests on the ground and raise their young in grasslands.

Loggerhead Shrike Lanius ludovicianus

32 The loggerhead shrike is a predatory songbird that hunts like a small hawk. Unlike hawks, however, shrikes do not have strong talons to hold onto their prey as they eat it. To compensate, these birds ingeniously impale their prey on barbed wire or thorny trees, a practice that has earned them the name ‘butcherbird.’ Impaling prey serves a num- ber of different purposes: holding prey, storing food for later, or attracting a mate by demonstrating a male’s hunting competence.

The loggerhead shrike has a heavy hooked , well suited to its hunting habits. From a perch on a utility pole or fencepost, shrikes engage in fast direct flights or swoop down to catch insects, rodents, small snakes or amphibians. Grasslands

The loggerhead shrike is a trim, handsome bird, with a black tail and wings, grey crown and back and white underparts. It has a characteristic black mask that extends above the hooked bill onto the forehead.

The loggerhead shrike was once quite common in agri- cultural southern Ontario, where it thrived on grazed grasslands with scattered low trees and thorny shrubs. As farming practices changed and more cash crops and confinement livestock systems were emphasized, shrike habitat dwindled. Other possible factors in its decline include pesticides and collisions with motor vehicles. Today, the loggerhead shrike is listed as Endangered. Only two dozen pairs are known to still breed in Ontario. These birds are nesting in areas where shallow soils overlie limestone bedrock, areas which tend to be marginal farmland that is being used as pasture for live- stock (Long Point Bird Observatory, 1997). In Ontario, shrikes breed almost entirely in two core areas: the Carden Plain and the Napanee Plain.

The fate of the loggerhead shrike lies mainly in the hands of individual landowners and with positive stewardship efforts. There are several ways in which habitat can be enhanced and managed for loggerhead shrikes (Long Point Bird Observatory, 1997):

• Shrikes are sensitive to disturbances during the breed- ing season, so leaving a refuge area around nests dur- 33 ing the breeding season is essential. • Leaving brush piles on cleared land provides nesting materials. • Trees, especially hawthorn and red cedars, provide habitat for perching, nesting and impaling prey. These can be planted in prime shrike habitat loca- tions. • Shrikes prefer short grasslands with scattered trees, so ensuring that pastures are grazed enhances their habitat. Rotational grazing helps to maximize the amount of habitat available for shrikes.

Grasslands Bobolink Dolichonyx oryzivorus

The bobolink’s striking black and white markings, long, clear bur- bling song and aerial displays make it an easily recognizable bird in rural Ontario. This member of the blackbird family is a long-dis- tance traveler, making its way from northern Argentina to breed in Canada and the . During migration, bobolinks can be found in large groups in wet meadows.

Bobolinks prefer habitats of medium-height grasslands and favour hayfields and lightly grazed pastures. Bobolinks, like many of the species discussed in this book, once benefited from increased agri- culture in Ontario, with hay production providing ready habitat. In fact, range maps show a clear link between agricultural areas and 35 bobolink abundance, and where there is no hay production, there are generally no bobolinks (Cadman et al, 1987).

Recent reports show that bobolink numbers are declining, a phe- nomenon which may be related to the widespread use of alfalfa as a hay crop, the harvesting of hay early in the season, and the declining acreage of pastures and hayfield in Ontario (Statistics Canada, 2001; Bollinger & Gavin, 1992).

Female bobolinks are drably coloured with brown and buff streaks. They lay four to seven gray eggs that are spotted with red-brown and lavender and which they incubate for 11– 13 days. Bobolink nests are a cup of grass, stems and rootlets on the ground. To help protect the nest site, females behave in a cryptic manner, rarely Grasslands carrying nesting materials and food directly to their nests, but land- ing and then walking through the fields to the nest. Similarly, they travel some distance from the nest before flushing.

Eastern Meadowlark Sturnella magna

Eastern meadowlarks sing the trademark tune of rural Ontario, boisterously calling ‘See-you at school-today’ throughout the spring. Their voices ring out from fenceposts and powerlines wher- ever grassy meadows, hayfields and pastures are found.

You will recognize an eastern meadowlark from the male’s black v- shaped ‘necklace,’ bright yellow throat and chest, and white outer tail feathers. Its sides and flanks are white with brown streaking.

Meadowlarks are artful builders, creating a domed grass nest with a side door in a depression or scrape on the ground. The nest is delicately woven into the surrounding vegetation. The female lays three to seven white eggs that are heavily spotted with brown and lavender, incubating them for 13-15 days.

36 Upland Sandpiper Bartramia longicauda

Upon hearing the ‘wolf whistle’ song of this species, you may turn around to see who is calling! Look for a graceful bird with long yel- lowish legs, a slender neck, lightly streaked breast and mottled brownish upper parts. Upland sandpipers frequently call from con- spicuous fenceposts, and breeding males will sometimes launch into the air to perform a courtship flight. Grasslands Once common in hayfields, grassy wet meadows, pastures and abandoned fields, this bird was commercially hunted for its meat in the late 1880s. Its numbers have recovered somewhat, but are still low (and possibly declining again) in Ontario.

These sandpipers build their grassy nests in depressions within pas- tures or hayfields. The female lays four pinkish-buff eggs with brown spots, and after an incubation period of 22–27 days, both adults tend the young.

37 Marginal Farmland

armland management is more economically and environmentally sound if it respects the productive Fcapacity of the land base (AAFC, 1996). When land is not suited to intensive row crop agriculture, it should be retired to pasture or natural cover such as woodland or grassland. Some examples of marginal farmland include:

40 Brown Thrasher Toxostoma rufum

Brown thrashers have one of the most extensive vocal repertoires of any North American bird, with an estimated 3,000 various com- binations of musical phrases! Most commonly, you will hear them sing a complex chorus of twice-repeated phrases.

Brown thrashers have vivid reddish-brown upper parts and are white below with dark brown streaks. Their large, curved beak, Marginal Farmland long tail and yellow eye no doubt strike fear into their main prey source – grubs and caterpillars. These birds also toss leaves aside to eat berries and seeds.

Despite the fact that brown thrashers are larger than a robin, they often go unnoticed since they are relatively secretive. They spend most of their time skulking about in thickets, field edges and over- grown pastures, especially those with hawthorns. Thrashers favour abandoned farmland, and often prefer areas away from human habitation. The twig and leaf nests of brown thrashers are usually constructed within the protected confines of hawthorn trees or raspberry bushes for added predator protection.

41 Eastern Towhee erythrophthalmus

The eastern towhee can sometimes be heard energetically tossing leaves as it scratches the leaf litter looking for insects and seeds. While this ground-dwelling bird generally prefers dense brush and tangles, the male can be heard singing its signature tune from ele- vated tree perches. Listen for two accented introductory notes fol- lowed by a quavering trill likened to ‘drink your tea-ea-ea.’ Marginal Farmland The eastern towhee is a bird of striking patterns and colours, espe- cially the male with its black back, hood and tail, white belly and rufous sides.

The cup-shaped nest of the eastern towhee is made of leaves, grass, twigs and rootlets, often lined with fine grass or hair and located in a scratched depression. The female lays three to four grayish to creamy-white eggs with brown spots. During egg-laying and incubation, the birds are very secretive. Once the eggs hatch, both the male and female help to raise the young.

Unfortunately, the eastern towhee is a frequent host of the brown- headed cowbird, a nest-parasite described in the following section.

42 Strip Habitat

trip habitat has nothing to do with bareness, and everything to do with vegetative cover! Strip cover Srefers to permanent corridors of vegetation such as fencerows, shelterbelts, windbreaks and grassy roadsides. Farms generally have significant amounts of strip habitat, which are configured in strips along the edges of fields or roadsides. These types of natural or planted corridors have long been recognized as beneficial on farms. Benefits include:

Cowbird Parasitism and Yellow Warblers

The brown-headed cowbird once followed bison herds in west- ern Canada. As the cowbirds’ range expanded eastward into Ontario, they began to inhabit areas where cattle were raised. Perhaps because of their nomadic lifestyle, cowbirds do not build a nest and rear their young. Instead, these birds have evolved as ‘nest parasites,’ laying their eggs in other birds’ nests. From the cowbird’s perspective, this parasitic strategy is a great way to let the host species do all of the work incubating and raising cowbird chicks. Indeed, cowbirds have been so suc- cessful that they now parasitize the nests of over 140 species of birds in North America.

Hosts of cowbird parasitism are generally smaller than the cow- bird. The host female expends considerable energy incubating the unusually large egg in her nest, but her work truly begins once the egg hatches. Cowbird eggs generally hatch earlier than their fellow eggs, and the nestlings develop much more quickly than their nestmates. As cowbird chicks grow, they demand significant food resources from their host mothers. They are often fed at the 46 expense of the legitimate offspring, who typically starve or are pushed out of the nest by the young cowbird.

The brown-headed cowbird is now common in Ontario. From elevated perches in strip habitat or along the edge of wood- lands, it locates and monitors the nests of potential hosts. Unfortunately, its ‘nesting’ strategy is a contributing factor to the decline of some North American songbirds. It has been esti- mated that nest parasitism, mainly from the brown-headed cowbird, is the single leading cause of nest failures across a wide range of species, habitats and locations, accounting for 80% of nest losses (Martin, 1993).

Yellow warblers are among the most frequent targets of cow- bird parasitism. Unlike many other birds, however, yellow war- Strip Habitat blers can recognize the eggs of brown-headed cowbirds when they find them in their nests. When this happens, the warblers will either abandon their nest or build a new nest on top of the old one and lay a new clutch of eggs. In an attempt to succeed against the persistence of cowbirds, yellow warblers have been known to stack more than five nests on top of one another! With this skill, and the bird’s generalist habitat requirements, it is not surprising that the yellow warbler is one of the most common warblers in North America.

Indigo Bunting cyanea

Upon first glance, the male indigo bunting may appear almost 47 black. When the sunlight diffracts on the bird’s feathers, however, the brilliant blue colour for which the indigo bunting is named will shine forth. In contrast, the female indigo bunting is soft brown overall, with brown streaks on her breast and a whitish throat. The indigo bunting is a tireless singer with a variable song of paired, accented notes likened to ‘fire-fire, where-where, here- here, see-it, see-it’.

Related to grosbeaks, the indigo bunting has a stout dark bill, which it uses to eat grasshoppers, beetles, grubs and weed seeds. It is a true strip habitat or ‘edge’ species, inhabiting orchards, shrubby fields, hedgerows, woodland edges and regenerating for- est clearings. Raspberry thickets are one of its favourite haunts. Strip Habitat Raspberry thorns protect its nest while it feeds concealed among the thickets.

Eastern Kingbird Tyrannus tyrannus

Eastern kingbirds look like they are ready for a black tie party. Their upper parts are uniformly dark gray to black and their under parts are bright white. The most distinguishing feature on these birds is the white band on the tip of their black tail. Their upright head feathers give them a somewhat pointy-headed silhouette.

Noisy and conspicuous, the eastern kingbird has been known to attack crows, hawks and humans intruding on its territory. The fearlessness and aggression of this bird doubtless earned it its com- mon name of ‘kingbird.’

In late summer or early fall, eastern kingbirds flock and feed on berries and insects, both of which they deftly snatch while on the wing. They prefer rural areas and woodland edge habitat, and are relatively easy to spot perched on utility wires and fenceposts along roadsides.

48 Woodlands

or birds and other wildlife in southern Ontario, it is vitally important that rural woodlands be main- F tained and restored. To fully appreciate the situation, consider the fact that prior to the arrival of European set- tlers, forests once covered about 90% of the region.

Scarlet Tanager Piranga olivacea

In Central and there are over 200 brightly coloured tanager species, but here in Ontario, the only nesting tanager is the scarlet version of this vast bird clan. Preferring extensive mature woodlands, scarlet tanagers feed and nest in the tallest reaches of the forest.

Despite their brilliant red , scarlet tanagers are surprisingly difficult to see as they dart and flit in the canopy in search of insect prey. During poor weather conditions when insects move lower in elevation, you may be lucky enough to see a tanager at eye level. Look for the black wings and tail and pale bill of the male and female birds. Breeding males have brilliant red bodies whereas non-breeding males and females are olive coloured above and yel- low below. Listen for them in large patches of deciduous or mixed forest cover. They sing a series of four to five whistled phrases, like a robin, but raspier - as if the robin had a sore throat.

Scarlet tanagers need interior forest habitat. They are very sensitive to the phenomenon known as forest fragmentation (when forests are cut up into smaller, more isolated patches by roads, urbaniza- tion, agriculture, etc.). They are one of the migratory bird species most sensitive to losses of forest cover in southern Ontario (Cadman, 1999; Villard, 1999). 53 Red-eyed Vireo Vireo olivaceus

Chances are you have heard a red-eyed vireo singing in the canopy or understorey of a woodland before. Male red-eyed vireos sing continuously through the day in the spring and summer, long after most other songbirds have finished their courtship performances. The woodlands seem to ring with their repetitive phrases, ‘Here I am! Where are you? Over here! Here I am!’ Indeed, red-eyed vire- os are capable of delivering more than 20,000 songs per day! Woodlands

Red-eyed vireos are best identified by their white eyebrow topped by their gray crown, olive green upper parts, white or pale gray underparts and lack of wing bars.

One of the most common and widespread birds in Ontario, red- eyed vireos are found in high concentrations in large deciduous woodlands with a shrubby understorey. Red-eyed vireos will inhab- it smaller forests than the scarlet tanager and will even nest in well wooded residential areas, with up to approximately one pair per half hectare in ideal habitat (Villard, 1999).

Common Yellowthroat Geothlypis trichas

This masked songster is a common visitor to wetlands across Ontario. The common yellowthroat belongs to the wood-warbler family. While its bright colouration seems in line with its kin, its preference for wet overgrown meadows and cattail marshes sets it apart from other wood-warblers.

Male common yellowthroats visit preferred singing perches in rota- tion and fiercely guard them from other males. From these spots, they sing their distinctive ‘witchity-witchity-witchity-witch’ song.

Common yellowthroats do, indeed, have a yellow throat, as well as a yellow breast and undertail coverts. Males also have a black mask with a white upper border. Their olive-green upper parts and dingy white belly contrast with their bright yellow throat. Female yel- lowthroats do not have the distinctive mask, but do have a white belly and may show a faint eye ring.

Common yellowthroats nest on or near the ground among emer- gent aquatic vegetation such as cattails and eat insects, including 62 dragonflies and beetles, and . Their nesting habits and food and cover preferences make them direct beneficiaries of buffer strips. American Woodcock Scolopax minor

These chunky little birds put on a springtime show that is worth the wait! In early evening, where open grassy areas abut wetlands, you may find an American woodcock wrapped up in his courtship displays. These birds strut or turn on the spot, stopping every quar- ter turn or so to call a loud ‘peeent’ in a nasal voice. After a num- ber of vocalizations, the woodcock twitters through the air in a circular flight display, and then plummets to the ground, zigzag- Water resources ging like a falling leaf. It is the woodcock’s rounded wings that make the noises you hear as the bird flies up and falls down in its display.

Other than during the breeding season American woodcocks are shy and inconspicuous birds. Their camouflaged plumage helps keep them well hidden in the moist woodlands and damp thickets adjacent to grassy areas where they live.

The woodcock’s long sturdy bill helps it to probe in soft soil for earthworms and insect larvae and to pinch snails, and seeds from plant material. The American woodcock has short legs and a short neck, and unusually large, dark eyes. Its most distinc- tive field marks are the light coloured bars on its otherwise black crown. These are arranged perpendicular to the direction of its bill, a feature that helps to distinguish it from the common snipe, which has facial and head stripes parallel to its bill. In addition, the woodcock’s brown or buff breast colourations differ from the snipe’s whiter breast plumage.
