Turati's Boubou

This brown woodpecker is restricted to western Mexico; barely enters the U.S. in southern Arizona. Face pattern similar to Hairy Woodpecker but brown instead of black. Back is entirely brown with no white. Males show small red patch on back of head, absent on females. Brown spots and bars on underparts. Found in mountainous oak forest. Makes a squeaky "peek" call.

A tiny-bodied sunbird in which breeding males are colorful and distinctive, and females and non-breeding males quite drab. Breeding males have a green back, a yellow belly, and extremely elongated central tail feathers. Females and non-breeding males have gray-brown upperparts and pale-yellow underparts. Similar to Nile Valley Sunbird, but there is very little overlap in range; males are distinguished by their lack of purple on the back and breast, and females by being darker overall and having a less distinct pale eyebrow. Also similar to female Beautiful Sunbird, but yellower below, with a shorter bill. The most common call is a rising “sweet,” and the song is a typical sunbird jumble. 

Striking diving duck of coastal harbors, mountain lakes, and large rivers. Very similar to Common Goldeneye. Males are easiest: Barrow’s has more black on the back, a downward-pointing spur on the side, and a crescent-shaped (not circular) white patch on the face. Females can be very difficult. Barrow’s usually has a yellow bill, but Common can rarely show a dull yellowish bill. Head and bill shape are important: Barrow’s has a steeper forehead and a puffy nape, and a shorter bill with a more rounded lower edge. Fairly common in western U.S. and Canada; much less common in the northeast. Small population in Iceland. Frequently found in mixed flocks with Common Goldeneye.
