Goeldi's Antbird

Large woodpecker, very similar to Northern Flicker. Overall pale sandy brown with gray face and brown crown. Spotted below with black oval on chest. Underwing and shafts of flight feathers bright yellow. Males have red mustache stripe; sexes otherwise alike. Combination of face pattern and yellow in wings helps distinguish from both "Red-shafted" and "Yellow-shafted" Northern Flickers. Shows a strong affinity for saguaro cactus but also found in nearby woodland. Gives a piercing "kleer" call similar to Northern Flicker.

Small flycatcher, extremely similar to several other species. Prefers shrubby open areas, especially around marshes. Western population prefers understory in riparian woods. Brownish above and pale below with barely any eyering. Wings dark with distinct white wingbars (brownish in Western population). Nearly identical to Alder Flycatcher; once considered the same species. Also compare with Least Flycatcher, which is very similar but has slightly shorter wingtips and a bolder eyering. Willow is larger, larger-headed, and longer-billed than other species of small flycatcher in the West; also note lack of a distinct eyering. Best identified by voice: song is a sneezing "FITZ-bew"; call is a dry "whit." Silent birds, especially in migration, often best left unidentified.

Small, yellowish bird with a fine black bill and distinctive black stripes on head. Mostly green above and yellow below; has rufous or orange crown bordered by black, but crown color can be difficult to ascertain. Note olive eyebrow becoming yellow in front of eye, and bright pinkish-yellow legs. Inhabits dense understory of foothill forests along the eastern slope of the southern Andes and in the tepui region. Usually occurs in pairs or small family groups that forage actively for insects, often joining mixed-species flocks. Song in tepuis is a series of chips followed by a high-pitched, screeching note. In southern part of range, song is very different: a rich rollicking series of notes that may vaguely recall House Wren and is often given by pairs as a duet. In southern Andes, most similar to Golden-bellied Warbler but has olive (not entirely yellow) eyebrow; also similar to Golden-crowned Warbler but typically occurs at higher elevations and has olive (not whitish) eyebrow.
