Lyon Arboretum Docent Manual Birds of Lyon Arboretum Lyon Arboretum Docent Manual Birds of Lyon Arboretum Commonly Sighted Birds at Lyon Arboretum 1. Common Mynah Acridotheres tristis This urban bird is common and widespread in lowland areas of all main Hawaiian Islands; recently established on Midway. Mynahs were introduced from India in 1865 to control army worms, an agricultural pest in pasturelands. The body is about 9 inches long, the two sexes are alike in plumage. The back and neck are brown, the head is black with yellow around the eye and on the bill and legs. Its call is mostly a chatter, sometimes mimicking other birds. Mynahs are loud, aggressive and often comical with their cocky walk. They nest in trees and buildings and can even be seen nesting in stop lights. At sunset, Mynahs often gather and noisily roost in trees. Their nest is made of grasses, leaves, paper and trash, and they especially seem to like shiny bits of plastic in the lining of the nest. The mynah has relatives that have been introduced to the mainland. These relatives include the Crested Mynah from Vancouver, British Columbia, and the Starling found throughout North America. 2. Common Waxbill Estrilda astrild Very small red-billed, brown finch with a prominent red streak from the bill through the eye. Rump brown, undertail coverts black. Introduced to O`ahu from Africa early 20th century. Escaped pet, first identified in late 1970s. Widespread on O`ahu. Smallest finch at the Arboretum. Commonly seen in large groups. The song is a weak twittering, chip-chip-tooee, chip-chip-tooee. 3. Feral Chicken Gallus gallus Feral chickens are commonly found in the lower Arboretum grounds, hiding amongst the shrubs and trees. These birds were probably released or escaped domestic chickens which now inhabit the Arboretum. Males (roosters) are brightly colored, larger than the lighter, duller colored hens. Common. 4. Goffin Cockatoo Cacatua goffini The Goffin Cockatoo is smaller than the Salmon-crested Cockatoo. Its body is white. Introduced from Tanimbar Island in the Spice Islands. Often seen perched high in the Arboretum’s Albizia trees (which are also native to the Moluccas. Goffins are long-lived parrots that eats pulp from seed pods of palms, macaranga, and seeds of blue marble tree. They drink water from water pockets in the trees. 5. Japanese White-eye (Mejiro) Zosterops japonicus This bird was introduced to O`ahu from Japan as a possible insect control in 1929, and to the Big Island (Hawai`i) in 1937, and there were several subsequent introductions into the 1940’s. Their diet includes insects, buds, fruit and nectar. White-eyes have increased dramatically, are fairly common in any lowland wooded area and are now recognized as a threat to Hawaii `Äkepa (from the Big Island). The Hawaii `Ākepa could face extinction from food stress caused by competition from Japanese White-eyes. White-eyes are a small olive green bird with a distinctive Revised 2009 Page 1 Lyon Arboretum Docent Manual Birds of Lyon Arboretum white eye ring, and are usually active and quick moving through brush and trees, constantly searching for insects. The Japanese White-eye is fairly common in wooded areas, traveling alone or in small groups. Its song is high pitched and it also has a scolding twitter call. It often includes mimicry of other species. Its nest is neatly woven of fibers and grasses, usually placed in the small horizontal fork of a branch. The Japanese White-eye is very similar in appearance to the native `Amakihi. The easiest way to distinguish them is the White Eye’s white eye ring. White-eyes are probably the most common land bird in Hawaiÿi. 6. Northern Cardinal Cardinalis cardinalis The Northern Cardinal is also known as the Kentucky Cardinal. They were released on several occasions between 1929 and 1931, and now are commonly found in the lowlands. It is one of 4 birds found in Hawaii’s lowlands that have crests. (The two species of birds with red crests are cardinals; the two with black crests are bulbuls). The male Northern Cardinal is all red with black around the base of its bill. The female is brown with some pink on her feathers. Both have pinkish red bills. Juveniles are like the female but the bill is dull brown. The call is a distinctive metallic “speet”. Songs loud, whistled melodies and trills: a slow trill followed by several slower, downslurred notes, and a long trill of liquid notes, dropping in pitch at the end. 7. Nutmeg Mannikin (Rice Bird) Lonchura punctulata The Nutmeg Mannikin also known as Rice Bird or Spotted Munia, was introduced to Hawaiÿi from Southeast Asia about 1865. It is the smallest bird in the Arboretum lowlands, only about four inches long. The male is dark brown, has a black bill, a darker face and a spotted brown and white breast. The female and juveniles are lighter brown. They can be seen in the grass in small flocks where they feed on the grass seeds. When rice was grown in Hawaiÿi this bird was a serious pest to rice growers. More recently Nutmeg Mannikins have devastated experimental sorghum crops. The best place to see this bird is on the lawn adjacent to the lower driveway in Lyon Arboretum. Its voice is a characteristic low- pitched, reedy “chee, ba-hee”, different in quality from the calls of most other small finches. (abundant) 8. Red-crested Cardinal Paroaria coronata The Red-crested Cardinal is also commonly known as the Brazilian Cardinal. Adult males and females each have a bold red head and crest, a gray back and tail, and a white breast and collar. The juvenile Red-crested Cardinal is the same size but has an orange-brown head and crest. The Red-crested Cardinal was introduced from South America around 1930. Both species of cardinals eat seeds, insects and fruits. Both species have open cup shaped nests. Calls are a buzzy “chink”. Songs a loudly whistled melody with evenly spaced lilting slurs and warbles. A greeting pair may utter an excited jumble of liquid whistles, chirps, and slurs. Revised 2009 Page 2 Lyon Arboretum Docent Manual Birds of Lyon Arboretum 9. Red-vented Bulbul Pycnonotus cafer There are two kinds of Bulbuls found at the Arboretum. The Red-vented Bulbul is one of the commonest birds seen in the Arboretum and is now well established all over O`ahu. Despite being classified as a “prohibited entry” it was an unplanned introduction from India (escaped cage bird) in about 1966. Stray birds are reported from Kaua`i, Moloka`i, Kaho`olawe and the Big Island (Hawai`i). The Red-vented Bulbul’s body is dark grey-black, except for a white rump seen when in flight, white tips to the tail and a red vent. The voice is a variety of rather low-pitched chirps and whistled phrases. Also has an elaborate dawn song of flute-like whistles. 10. Red-whiskered Bulbul Pycnonotus jocosus The Red-whiskered Bulbul is found in a few residential sections of Honolulu (the Mānoa Makiki area is their main population center). It is another introduction from India, first reported in 1967. It has a white breast, (which the Red-vented Bulbul does not have). The crest is thinner, and more pointed. It has a reddish- orange vent and a small crimson patch below the eye. In both Bulbuls, the male and female are alike. Bulbuls do resemble Cardinals but they are not closely related. The voice is similar to, but higher pitched than that of the Red-vented Bulbul. Phrases varied but always with a gurgling quality. Call is similar to but more piercing than the House Sparrow’s. 11. Salmon-crested Cockatoo Cacatua moluccensis First seen in the Arboretum in 1967, (2-3 in 1980’s). Probably escaped pets or from Paradise Park’s captive breeding program. Pink colored crest. From a single island in the Moluccas Islands in Indonesia. Reported to be one of the 50 rarest birds in the world. In the Moluccas, birds were trapped in great numbers for export for the pet trade. 12. Spotted Dove Streptopelia chinensis The Spotted Dove is about 12 inches long. The sexes are similar, grayish brown body with a rosy breast. It has a black and white spotted band around the back and sides of its neck. The Spotted Dove was introduced from Asia in the mid- 1800s, and was reported to be common on O`ahu by 1879. Its nest is a flimsy twig platform in a tree or bush. They have an elaborate courting display of bowing and tail flaring. Spotted Doves are commonly seen on the grass or pathways feeding on seeds, or perched on overhead utility wires. They are also known as Lace-neck Doves, Ring-neck Doves, or Chinese Doves. The song is a variable low hoarse “coo”, typically “coo-WHOO-coo”. Common. 13. White-rumped Shama Thrush Copsychus malabaricus The Shama Thrush was intentionally introduced to Kaua`i in 1931 from Malaysia, and released on O`ahu in 1940. Mr. and Mrs. Caum, who lived in the main cottage at Lyon Arboretum, kept caged birds and released them, so Lyon Arboretum was probably one of the earliest Shama introduction sites on O`ahu. Shamas have very melodious, rich songs and are noted as one of the most beautiful songbirds in the world. They appear relatively unafraid of people, and often follow our gardeners Revised 2009 Page 3 Lyon Arboretum Docent Manual Birds of Lyon Arboretum around, an example of opportunistic feeders using garden staff and volunteers to help locate small insects, earthworms and centipedes for their dinner.

We visited Timor, Sumba, Flores and Komodo in search of Indonesia’s rarest and least known species, ending up on Bali in search of the famous starlings. These islands are relatively undeveloped, thinly populated and seldom visited by birders but they gave us access to some of the rarest birds on the planet. Starting on the largest island, Timor with its dry grassland, acacia scrub and montane forest, it is home to the greatest number of endemics. We had to split our time here in two due to a last-minute rescheduling of our internal flights and this did affect our success here a little but we still managed to see most of what the island has to offer. Then we flew across to the arid island of Sumba which is the most isolated and least often visited.

  • Status and Habitat Associations of Birds on Lembata Island, Wallacea, Indonesia, with Reference to a Simple Technique for Avifaunal Survey on Small Islands
    Bird Conservation International (2002) 12:365–381. BirdLife International 2002 DOI: 10.1017/S095927090200223X Printed in the United Kingdom Status and habitat associations of birds on Lembata Island, Wallacea, Indonesia, with reference to a simple technique for avifaunal survey on small islands COLIN R. TRAINOR Summary The islands of Wallacea were surveyed most intensely by field ornithologists in the nineteenth century, and again in the 1990s. However, the status and habitat use of bird species on many islands remains unknown. This study examined birds in several natural and disturbed habitats on Lembata (also known as Lomblen) Island, Indonesia. A total of 78 bird species were recorded including six endemic to the Lesser Sundas, an additional three Wallacean endemics and a total of 27 resident forest species. Including published records, 91 bird species have been recorded for Lembata. Extrapolation from the cumulative number of new species in the 45 samples gave an expected Total Bird Richness of 103.4 species. The frequency of occurrence of Lesser Sundas endemic bird species, all Wallacean endemics and Lesser Sundas endemic subspecies, forest-dependent species and frugivores was greatest in closed canopy forest (at higher elevations). Conversely, generalist ‘‘Australo-Papuan’’ species, granivores and nectarivores occurred more frequently in lowlands (including human-modified habitats). Protected area proposals were made in 1982, but there has been no management of natural areas for biological conservation on Lembata. Conservation activities aiming to stem forest loss and fragmentation in an Important Bird Area in southern Lembata, which includes significant populations of the Flores Green Pigeon Treron floris (Globally Vulnerable), may be an important step.

  • Eastern Sumbanese Bird Classification
    Jo urna l of Ethnobiology 20(2): 161-192 Winter 2000 EASTERN SUMBANESE BIRD CLASSIFICATION GREGORY FORTH Department of Anthropology University oj Alberta Edmonton, Alberta, Canada T6G 2H4 To Oemboe Hina Kapita and to the memory of Louis Onvlce (l893~1986) ABSTRACT.-Tn regard to ethnozoological classification, the Austronesian­ speaking area of insular Southeast Asia is one of thc least documented parts of the world. Dictionaries of the language of eastern Sumba by Kapita (1982) and Onvlee (1984) include over fifty names for kinds of avifauna with glosses in Indonesian (Bahasa Indonesia) and Dutch as well as scientific identifications drawn mostly from fieldwork conducted by the naturalist Dammerman in the 1920s. Combining these data wi th ethnoornithological information collected by the author in the domain of Rindi, the eastern Sumbanese classification of birds is discussed with regard to nomenclature, internal structure, and its relation to a general ethnozoological taxonomy. On the basis of recent ornithological stud ies of this part of Indonesia, the association of Sumbanese categories with scientific taxa is also reviewed . Finally, the prominence of certain bird ca tegories in the symbolic idioms of ritual speech, myth, and augury is considered as a factor hypothetically linked with eastern Sumbanesc ethnoornithological classification. Key words: eastern Sumba, Rindi, naming and classification of birds, ethno:lOological taxonomy, symbolism. RESUMEN.-EI area de habla austranesia del sudoeste insular de Asia es una de las partes menns documentadas d el mundo en relacion a la clasifici6n etnozool6gica.

  • A Global Study of the Distribution and Richness of Alien Bird Species
    A global study of the distribution and richness of alien bird species Ellie E. Dyer A dissertation submitted for the degree of Doctor of Philosophy University College London Centre for Biodiversity and Environment Research (CBER) within the Department of Genetics, Evolution and Environment (GEE) University College London November 4, 2015 Declaration I, Ellie Eveness Dyer, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Ellie Dyer, 4th November 2015 2 Abstract Alien species are a major component of human-induced environmental change, yet spatial and temporal variation in the drivers of their introduction, and their subsequent distribution and richness, are poorly understood. Here, I present a global analysis of the drivers of this variation for a major animal group, birds (Class Aves), using the newly-created Global Avian Invasions Atlas (GAVIA) database. GAVIA includes information on introduction successes and failures, enabling me to examine the effect of colonisation pressure (the number of species introduced) on alien bird distributions. A description of the GAVIA database is given in Chapter 2, with details on its scope and sources, data collation and validation, and the production of alien range maps. Chapter 3 focuses on the early stages of the invasion pathway, and shows that historical introductions tend to originate in Europe, were driven by the global movements of British colonialism, and involved species deemed useful. Modern introductions, in contrast, tend to originate in Southeast Asia and Africa, are driven by factors associated with wealth, and involve species found in the pet trade.

Our tour commenced on Sumba where we pretty much cleaned up on all of the endemics including great looks at Little Sumba Boobook, Mees’s Nightjar, Sumba Hornbill, Sumba Myzomela and others. Next up was Rote Island where we saw Rote Boobook, Rote Myzomela and the distinctive Rote Leaf-Warbler, plus a number of other ‘Timor’ endemics as well. Back on Timor we nailed Timor Boobook, Black-banded Flycatcher and Orange-banded Thrush before setting off to the beautiful island of Flores. Our attempts at Flores Scops-Owl proved rather fruitful with point-blank views that none of us will ever forget, and there was also Flores Hawk-Eagle, more Elegant Pittas, and the dawn chorus of Bare-throated Whistlers just has to be experienced.

  • The Cage Bird Trade in Bali SERENE C
    FORKTAIL 34 (2018): 35–41 In the market for extinction: the cage bird trade in Bali SERENE C. L. CHNG, KANITHA KRISHNASAMY & JAMES A. EATON This paper is the first known complete inventory of birds sold in two of the largest bird markets in Denpasar, Bali, Indonesia. Two inventories were compiled one year apart, in 2017 and 2018. A total of 5,228 individuals of 129 species were recorded in 2017 and 7,258 individuals of 144 species in 2018, including eight threatened species, seven in both years and one additional species in 2018 only. Most of the birds recorded are believed to be wild-sourced. A higher proportion (7.8%) of birds from eastern Indonesia (those only distributed on the Lesser Sundas, Sulawesi, Maluku and Papua) were found for sale in Bali in 2018 compared with 2017 (2.8%), and compared with markets in Jakarta (0.7%) and eastern and central Java (1.9%). Continued monitoring of key markets is needed to verify whether the supply of some species in the markets is declining owing to trapping pressure in the wild, and if this leads to other species, such as eastern Indonesian and montane species, being increasingly sought to supply the bird trade in Bali and elsewhere in Indonesia. We urge the Indonesian authorities to utilise information from such trade surveys to make informed decisions regarding species protection and trade regulation, including a periodic review of P.92/2018, Indonesia’s newly released species protection legislation. This will be particularly important for species whose wild populations are dwindling, and for which capture and trade from the wild should be prohibited to prevent extinction in the wild, a fate that some Javanese bird species already face.

Ecologically heavily influenced by the dry south-west monsoon that batters the islands in May–September, it boasts high endemism in plants, reptiles, insects and birds, which I will summarise. Whilst its avifauna is species-poor, with just 42 regular breeders, 11 are endemic, making it the richest area of avian endemism in the Middle East (along with the highlands of south-west Arabia). From 1999 to 2011, I have been engaged in mapping the distribution and determining the populations of the breeding species and I will present some of my findings.

  • Lesser Sundas Island Endemics & Komodo Island Dragons Trip Report 1St to 18Th September 2015
    Lesser Sundas Island Endemics & Komodo Island Dragons Trip Report 1st to 18th September 2015 Flores Monarch by Marcel Holyoak Trip report compiled by Tour Leader: David Erterius RBL Indonesia – Lesser Sundas Trip Report 2015 2 Tour Summary Situated to the south of Sulawesi and east of Bali, the Lesser Sundas is made up of a wonderfully diverse group of islands. Their isolation, together with an array of varied habitats, makes this another endemic hotspot, and our highly successful tour visited 4 main islands, namely Sumba, Timor, Flores and Komodo - where we recorded an incredible 85 endemics. The tour started on the low-lying coralline island of Sumba in central Lesser Sundas. Lying relatively isolated to the south of the main chain of the Lesser Sundas, Sumba is of considerable biogeographic interest, and during our first five days of the tour that were spent on this island, we racked up no less than 10 species that are found on Sumba and nowhere else in the world. Most of these were located in the dry Black-fronted Flowerpecker by Marcel Holyoak deciduous forests of the island and included the two tricky endemics, Sumba Brown Flycatcher and Sumba Flycatcher, the lovely Sumba Myzomela and Apricot-breasted Sunbird, smart Sumba Green Pigeon and exquisite Red-naped Fruit Dove as well as the peculiar looking Sumba Hornbill. Our nightly escapades in this area yielded two endemic owl species as well, namely Sumba Boobook and Little Sumba Hawk-Owl, the latter so new to science that it wasn’t even included in the Wallacea field guide from the late nineties! Furthermore, we managed to find Sumba Buttonquail during an extensive search in the vast open grasslands of the island.

  • ZEBRA DOVE Geopelia Striata
    ZEBRA DOVE Geopelia striata Other: Barred Dove (<1983), Peaceful Dove (see below) monotypic naturalized (non-native) resident, long established Geopelia doves have been successfully introduced to Indian Ocean islands, Indonesia, the Philippines, Tahiti and in the Hawaiian Islands (Long 1981, Lever 1987), where they have become one of the most abundant bird species (Pyle 1995). The Zebra Dove is native to the Malay Peninsula, the Philippine Is, and Indonesia, but species limits within the genus Geopelia doves in the Austalasian region remain unresolved (Schodde and Mason 1997). The Peaceful Dove (G. placida) of s. New Guinea and Australia and the Barred Dove (G. maugei) of the Lesser Sundas and Molucca Is are similar and have been treated as part of G. striata (e.g. Long 1981, Higgins and Davies 1996) but most authors (Harrison 1969; AOU 1983, 1998; Monroe and Sibley 1993; Schodde and Mason 1997; Clements et al. 2016; Gill and Donsker 2016) treat them as three separate species (see Non-established List). Three subspecific taxa, tranquilla and clelandi of Australia and papua of New Guinea, have been variously treated as belonging to Zebra Dove (e.g., Howard and Moore 1994) or Peaceful Dove (e.g., Schodde and Mason 1997, Clements 2007, Gill and Donsker 2016); we follow most recent treatments in considering Zebra Dove as monotypic. A small group of Zebra Doves were reportedly brought to Kaua'i, O'ahu, Moloka'i, and Maui in 1922, possibly from a Singapore dealer (Bryan 1958). They were identified then as G.s. striata (Munro 1944, Swedberg 1967b, Walker 1967) but the shipment was also reported to have included some Barred and Peaceful doves (see above; Caum 1933, Bryan 1937, Munro 1944, Bryan 1958, Swedberg 1967b).
