September 9, 2022 – Chestnut-tipped Toucanet (Aulacorhynchus derbianus)
These toucans are found in cloud forests on the eastern slope of the Andes from southern Colombia to central Bolivia. They eat mostly fruit and seeds, along with some insects, foraging in the canopy alone, in pairs, or sometimes in small flocks. Little is known about their nesting behavior, though they may breed from May to October.
September 8, 2022 – Pallas’s Leaf Warbler (Phylloscopus proregulus)
Breeding in parts of Russia, Mongolia, and China, these leaf warblers winter in southern China and parts of northern Southeast Asia. They are also often seen as vagrants in Europe. Frequently foraging with mixed-species flocks, they eat insects and spiders, plucking them from leaves, often while hovering, or catching them in the air. Females build the nests from twigs, plant fibers, leaves, moss, and other materials.
September 7, 2022 – Rufous-winged Antshrike (Thamnophilus torquatus)
Found in parts of Bolivia, Brazil, and Paraguay, these antbirds live in savannas, thickets, and scrub. Foraging in pairs or alone, usually near the ground, they feed on insects, including caterpillars, grasshoppers, and beetles. Pairs build cup-shaped nests from fine grass stalks, rootlets, and fungal fibers where females usually lay clutches of two eggs. Both parents incubate the eggs and feed the chicks.
September 6, 2022 – Western Nicator (Nicator chloris)
These nicators are found in western and central Africa in forests, swamps, and shrubland. Foraging in pairs and sometimes joining mixed-species flocks, they eat mostly insects and other arthropods. They build small, somewhat flimsy nests from sticks, tendrils, and other materials where females lay a single egg and incubate it alone.
September 5, 2022 – Tawny-faced Gnatwren or Half-collared Gnatwren (Microbates cinereiventris)
Found from parts of southern Nicaragua to northern Bolivia, these birds in the gnatcatcher family live in lowland forests. Foraging in the understory, they eat insects and spiders, often joining mixed-species flocks and sometimes following ant swarms. Little is known about their breeding behavior, as very few of their nests have been found, but they may construct them from green moss, plant fibers, and other materials in shrubs. Both parents care for the chicks.
September 4, 2022 – Narrow-billed Woodcreeper (Lepidocolaptes angustirostris)
Found in parts of Argentina, Bolivia, Brazil, Paraguay, Suriname, and Uruguay, these woodcreepers live in open woodlands, savannas, and agricultural areas with some trees. Often joining mixed-species flocks, they forage on tree trunks and wooden fences for insects, spiders, other invertebrates, and possibly small frogs and lizards. They nest in cavities in trees where both parents incubate the eggs and feed the chicks.
September 3, 2022 – Speckle-fronted Weaver (Sporopipes frontalis)
Found in parts of central and eastern Africa, these weavers live in savannas and woodlands. They eat seeds and some small insects, foraging mostly on the ground, usually in small flocks outside of the breeding season. Nesting solitarily or in small colonies, they build messy ball-shaped nests with side entrance tunnels from dry grass and other materials in shrubs or trees. Females lay clutches of two to four eggs and probably incubate them alone. Both parents feed the chicks.
September 2, 2022 – Blue-chinned Sapphire or Blue-chinned Emerald (Chlorestes notata)
These hummingbirds are found in northern South America, primarily in the Amazon basin and Brazil’s coastal forests. They feed mostly on nectar as well as some insects, defending flower patches from other hummingbirds. Females construct deep cup-shaped nests from lichen and fine plant fibers bound with spiderweb, where they incubate the eggs and care for the chicks alone.
