Bolivian Tyrannulet

Zimmerius bolivianus

Small, pale olive-gray flycatcher. Found across a wide elevational range from montane forest all the way up to elfin forest and scrub around the treeline. Perches horizontally, holding its head up; has a pale eye and lacks wingbars. Very pale belly helps distinguish it from the similar Red-billed Tyrannulet, which has a yellow belly and which overlaps with Bolivian at the lower part of Bolivian’s elevational range. Bolivian’s call is a single, descending whistle.

African Citril

African Citril

Crithagra citrinelloides

A small seedeater with a sharp bill and a forked tail. The upperparts are olive-green and the underparts yellow. Males have a black face and plain yellow underparts. Females have a plain face, but are heavily streaked below. Found at middle and high elevations in a variety of habitats including forest edge, gardens, cultivation, moist scrub, and woodland. Usually in small flocks. Similar to Southern Citril, but there is virtually no overlap in range, and the male is easily separated by its black face. The song is a fast jumble of high-pitched twitters and whistles. 

Common Wood-Pigeon

Common Wood-Pigeon

Columba palumbus

Distinctive, large bulky gray pigeon with a pale neck patch (lacking on juvenile in late summer–autumn). Neck patch is large and white throughout majority of range, but birds in Azores, Madeira, and much of western Asia have smaller, tan-colored patches. Bold white wing band striking in flight; tail broadly tipped black. Inhabits wooded and semiopen habitats, including towns and gardens. Forms flocks, especially in winter. Often rather unaware, and frequently crashes noisily and clumsily out of hedges and bushes. Display flight consists of a flap-flap-flap climb followed by a descending glide. Gives a low, throaty series of coos: “hrrruu-hoo-who-who.”

Golden-rumped Flowerpecker

Golden-rumped Flowerpecker

Dicaeum annae

A tiny, nondescript, short-tailed songbird with a stubby bill. Olive above and pale below, with gray-washed flanks and a white moustache in both sexes. Males show a yellow rump that is absent in females. Juveniles resemble females but are duller below, with a pale-based bill. Pairs and singles can be found high in trees in wooded areas, forest patches, and edges within the lowlands and mountains. Restricted to the Lesser Sundas. Pale moustache and all-dark undertail separate this species from Thick-billed Flowerpecker. Gives a very high-pitched descending series, “tzee-tzee-tzee-tzee-tzeer-tzeer…”, as well as a soft trilling sound.
