分类信息
The Ecuadorian ground dove and three other species were for a time placed in genus Columbigallina, which was later merged into Columbina. It was also formerly treated as a subspecies of ruddy ground dove (C. talpacoti) and forms a superspecies with it now.<p>The Ecuadorian ground dove has two subspecies, the nominate C. b. buckleyi and C. b. dorsti.

The nominate subspecies of Ecuadorian ground dove is found from Esmeraldas Province in north-western Ecuador south to Peru's far northern Department of Tumbes. C. b. dorsti is found separately, in the Marañon Valley of north-western Peru. They inhabit a range of landscapes including dry open semi-deciduous and deciduous woodland and thicker woodland, gardens, agricultural areas, and more humid young secondary forest. In elevation the species ranges from sea level to 2,000 m (6,600 ft).

White-browed Tailorbird
Orthotomus nigriceps
A small, long-billed, long-tailed bird of dense undergrowth in lowland and foothill forest in eastern Mindanao. Has an olive-green back and wings, an olive-green tail often held cocked, a pale gray belly, a black crown, and a white brow. Throat and chest are black in the male and white in the female with streaking around the edge. Similar to Rufous-fronted Tailorbird, especially from behind, but White-browed has black on the head with a white brow. Voice includes monotonous piping notes given in series, or a rapid whistled trill which can be rising or falling.
Rusty-backed Spinetail
Cranioleuca vulpina
A small long-tailed bird found in gallery forests near water, mostly foraging in the understory. Rusty above and pale below with a white eyebrow. Similar to Yellow-chinned Spinetail, but has a pale (not black) lower mandible. The song, usually given as a duet, is a series of high-pitched notes.
Thick-billed Cuckoo
Pachycoccyx audeberti
Huge cuckoo that is black above and white below. Immature has white barring across its upperparts. Looks raptor-like in powerful, swooping flight. Uncommon bird of rainforest, gallery forest, and moist woodland, especially miombo. Call is a loud, repeated “wheet-it”, often given in a high display flight. Adult is separated from Great Spotted, Levaillant’s, and Pied cuckoos by its lack of a crest or white in the wing. Immature is similar to Great Spotted Cuckoo, but has black-and-white speckles on the head, and lacks a crest.
