June 4, 2018 – Azores Bullfinch (Pyrrhula murina)
These bullfinches are found only in the eastern part of the island of São Miguel in the Azores. Feeding on almost forty different plant species, their diet changes with the seasons and includes a variety of seeds, fruits, flower buds, and other plant foods. They breed from mid-June to late August, building twig nests lined with rootlets, grasses, and moss. Common within their range until the 1920s, when habitat loss and hunting caused a large population decline, they are now classified as Vulnerable by the IUCN. While their numbers are currently thought to be stable, they still face threats from forest clearance, introduced plant species, low genetic diversity in their small population, and possible predation from rats and other mammals.
May 31, 2018 – Pale-billed Parrotbill, Black-browed Parrotbill, or Lesser Rufous-headed Parrotbill (Chleuasicus atrosuperciliaris)
These parrotbills are found in parts of India, Bangladesh, Bhutan, Myanmar, southern China, Thailand, Laos, and possibly Vietnam. Their diet is made up of small seeds, insects, such as beetles and grasshoppers, and spiders. They build deep cup-shaped nests from grass, bark, bamboo leaves, and other materials. Though they are classified by the IUCN as a species of Least Concern, their population is declining due to habitat destruction and fragmentation.
May 27, 2018 – Chestnut Bulbul (Hemixos castanonotus)
These bulbuls are found in the forests of southeastern China and northern Vietnam. There diet includes large quantities of berries and other small fruits, as well as insects and their larvae. Territorial pairs breed between May and July, usually raising two or more broods of chicks. Females build the deep cup-shaped nests.
May 23, 2018 – Dark-sided Flycatcher (Muscicapa sibirica)
Breeding across most of Eastern Asia and in parts of South Asia, these flycatchers winter in Southeast Asia. Their diet is not well studied, but is primarily made up of small invertebrates, which they hunt from branches, making small flights to capture their prey. Breeding from May to August, females build compact, cup-shaped nests from moss, lichens, fine grasses, hair, and feathers.
May 19, 2018 – Chorister Robin-chat or Chorister Robin (Cossypha dichroa)
These birds are found in evergreen forests in parts of South Africa, Lesotho, and Swaziland. They eat mostly insects, along with some fruit, foraging on the ground or in vegetation. Breeding from October to December, the females build open cup-shaped nests from moss roots, leaves, lichen, grass, and other materials in tree cavities. Females do all of the incubation, but both parents feed the chicks.
May 15, 2018 – Kessler’s Thrush or White-backed Thrush (Turdus kessleri)
These thrushes are found in central China and parts of northeastern India. They mostly eat insects and worms during the summer, berries in the fall, and juniper berries in the winter, usually foraging on the ground. Breeding from May to August, they build their nests close to the ground in rocky areas with vegetation. Males join large foraging flocks during the breeding season.
May 11, 2018 – Chestnut-sided Warbler (Setophaga pensylvanica)
Breeding in southeastern and central Canada and the northeastern United States, these warblers migrate to parts of Mexico and Central America. Individual birds often rejoin the same mixed-species foraging flocks on their wintering grounds each year. Although they occasionally eat some berries, their diet is mostly made up of arthropods, which they pluck from foliage, sometimes while hovering. Females build cup-shaped nests in shrubs or saplings from bark, weed stems, grasses, plant down, hair, and rootlets. Though only the females incubate the eggs, both parents care for the chicks.
