Barred Owl (Strix Varia)
Wild Things in Your Woodlands Barred Owl (Strix varia) The barred owl is a large bird, up to 20 inches long, with a wingspan of 44 inches. It is gray-brown in color, with whitish streaks on the back and head, brown horizontal bars on its white chest, and vertical bars on its belly. This owl has a round face without ear tufts, and a whitish facial disk with dark concentric rings around brown eyes. Males and females look similar, but females can weigh about one third more than males. “Who cooks for you, who cooks for you all?” This is the familiar call of the barred owl defending its territory or attracting a mate. If you live in or near a heavily wooded area with mature forest, particularly if there is also a stream or other body of water nearby, this sound is probably familiar. Barred owls are the most vocal of our owls, and most often are heard calling early at night and at dawn. They call year-round, but courtship activities begin in February and breeding takes place primarily in March and April. Nesting in cavities or abandoned hawk, squirrel, or crow nests, the female sits on a nest of 1-5 eggs for 28 to 33 days. During this time, the male brings food to her. Once the eggs have hatched, both parents care for the fledglings for at least 4 months. Barred owls mate for life, reuse their nest site for many years, and maintain territories from 200 – 400 acres in size. Barred owls are strongly territorial and remain in their territories for most, if not all, of the year. -

Barred Owl (Strix Varia)
Barred Owl (Strix varia) DID YOU KNOW: The rich baritone hooting you may hear in the woods that sounds like 'who cooks for you, who cooks for you-all' is the barred owl. They get their name from the dark barred pattern on the feathers. EATING HABITS: Barred owls are well-adapted for hunting small mammals, reptiles and birds; they will even eat fish! Their sharp talons and beak are perfect for grabbing, killing and tearing the meat. They seek prey from a perch or while flying low through the forest. They are most active at night, but will also hunt early in the morning and at dusk. The male hunts for food and brings it to the nest when the female is with the young. Lakeside Nature Center 4701 E Gregory, KCMO 64132 816-513-8960 www.lakesidenaturecenter.org THE YOUNG: The adult pair chooses a large hollow in a tree to make their nest. Sometimes they may even use an old abandoned hawk or squirrel nest. The pair calls to each other often when preparing to raise their family. The female lays two to four eggs that hatch in about 30 days. The babies look like big puffballs while they are covered with down. The feathers soon begin to grow in, and they are able to fly in about six weeks. HABITAT (HOME): Barred owls can be found from the East Coast to the Rocky Mountains, from Canada to the Gulf Coast. Woodlands that are near rivers and other wetlands are prime barred owl habitat. Locally you can hear or see barred owls where the Missouri and the Blue Rivers run through wooded areas. -
GREAT BLUE HERON (Ardea Herodias)
GREAT BLUE HERON Oneida Lake Status: (Ardea herodias) Common • Largest heron in North America • Often found in shallow water looking for food • Strongly affected by human contact The great blue heron is the largest heron in North America, with a wingspan as large as 84 inches and weighing up to 7 pounds. Adults have bluish gray wings and white heads decorated by a black streak above the eye. They have long Great blue heron in the wild necks streaked with white, brown, and black, and a long yellow beak that tapers to a point. Heron legs are long, thin, and greenish-yellow in color. Great blue herons can be found in marshes and swamps (including Cicero Swamp), flooded meadows, and along Oneida Lake’s shallow water shoreline, but they always Great blue herons boast a large live near water. Herons forage wingspan when flying while standing in water, and are most active around dawn and dusk. They locate their food by sight, and spear prey with their long, sharp bill. Using this method, herons eat fish, frogs, insects, snakes, turtles, Note the distinctive bill, and “S” rodents and small birds. Herons shaped neck (www.sfwmd.gov/org/erd/krr) swallow their prey whole, and have been known to choke on prey that is too large.

Montana Owl Workshop April 19-24, 2019 © 2018
MONTANA OWL WORKSHOP APRIL 19-24, 2019 © 2018 High, wide, and handsome, Montana is the country’s fourth largest state, encompassing 145,392 square miles (376,564 square kilometers), and has one of the lowest human densities of all states; about six to seven people per square mile. Its biological diversity and variable climate reflects its immensity. Among its alpine tundra, coniferous forests, plains, intermountain valleys, mountains, marshes, and river breaks, Montana lists 433 species of birds, 109 species of mammals, 13 species of amphibians, and 18 species of reptiles. Montana also maintains about 2,080 species of native plants. Join researchers for four full days of learning how to survey, locate, and observe owls in the field. Montana boasts the largest number of breeding owl species in any state within the United States. Fifteen species of owls occur in Montana, of which 14 species breed: American Barn Owl, Flammulated Owl, Eastern Screech Owl, Western Screech Owl, Great Horned Owl, Barred Owl, Great Gray Owl, Northern Hawk Owl, Northern Pygmy Owl, Burrowing Owl, Boreal Owl, Northern Saw-whet Owl, Long-eared Owl, and Short-eared Owl. Snowy Owls are winter visitors only. Although all species will not be seen, chances are good for five to seven species, and with some luck, eight species are possible. Highlights can include Great Gray Owl, Northern Pygmy Owl, Boreal Owl, and Northern Saw-whet Owl. It’s not often the public has an opportunity to follow wildlife researchers on projects. During this educational workshop, we will meet and observe field researchers of the Owl Research Institute (ORI) who have been conducting long-term studies on several species of owls. -
Raptor Mews: Meet Our Birds
Raptor Mews: Meet our Birds Birds of Prey or “Raptors” are birds with hooked beaks and sharp talons that are strict carnivores: they only eat other animals in order to survive. Hashawha houses several raptor species at the Raptor Mews. These have been evaluated and deemed non-releasable by veterinarians and rehabbers. They are part of our educational programs at Bear Branch Nature Center and Outdoor School. Eastern Screech Owl Otus asio Eastern Screech Owls are the smallest species of owl found in Carroll County. Their color pattern can vary from bright red to gray. The strong patterns on the belly and back, as well as the ear tufts, allow them to blend in with their environment, making it easier to hunt for prey and hide from predators. Though they are predators, they frequently fall prey to larger owl species themselves. Barred Owl Strix varia Also known as ‘Swamp Owls’, Barred Owls can be found mainly in hardwood marsh areas. They are mostly nocturnal, and usually like to hunt at night. However, it is not uncommon to see one in the late afternoon, getting a jump on the day’s hunting. They will eat a variety of prey, including mice, frogs, and even crayfish! Barred Owls have a very distinct call. If you listen closely, it sounds like they are asking a question: “Who cooks for you, who cooks for you all?” Great Horned Owl Bubo virginianus These ‘tigers of the night’ are amazing creatures. Great Horned Owls are the top predator in the woods at night. They are extremely powerful and able to carry much larger prey in relation to their body size then other birds of prey. -
Effects of Nesting Bald Eagles (Haliaeetus Leucocephalus) On
Note Effects of Nesting Bald Eagles ( Haliaeetus leucocephalus ) on Behaviour and Reproductive Rates in a Great Blue Heron ( Ardea herodias ) Colony in Ontario BILL THOMpSON 93 Donald Street, Barrie, Ontario L4N 1E6 Canada; email: [email protected] Thompson, Bill. 2017. Effects of nesting Bald Eagles ( Haliaeetus leucocephalus ) on behaviour and reproductive rates in a Great Blue Heron ( Ardea herodias ) colony in Ontario. Canadian Field-Naturalist 131(4): 369 –371. https://doi.org/10.22621/ cfn.v131i4.1848 Bald Eagles ( Haliaeetus leucocephalus ) and Great Blue Herons ( Ardea herodias ) are known to occasionally nest in mixed colonies, even though the former is one of the primary predators of the latter. I observed the two species in four heron colonies near Lake Simcoe, Ontario during two field seasons to assess whether rates of heron chick mortality or nest abandonment were greater in a colony that supported a nesting pair of Bald Eagles than in three nearby single-species colonies. I assessed the effects of eagle presence on heron behaviour using heron movement rates, the number of heron sentries left in colonies during the nesting period, heron nest mortality rates, and the average number of successfully fledged herons per nest. There was no statistically significant difference in movement rate among the four colonies, proportion of birds remaining as sentries, nor nest mortality rates. However, nests in the mixed colony successfully fledged significantly more heron young per nest than did nests in the single-species colonies. The mixed colony was located in a wetland and open lake system that provided extensive foraging habitat and an abundance of the preferred fish prey species of both Great Blue Herons and Bald Eagles, thus reducing predation pressure on the herons. -
