Monteiro's Hornbill
Tockus monteiri
Brown hornbill with a white belly and a yellow-and-orange bill. The white outer tail feathers and wing patches are conspicuous in flight. Found in arid savanna. Usually solitary or in pairs; sometimes in small flocks. Call is a series of clucking notes that accelerates and becomes louder. Fairly similar to Bradfield’s Hornbill, but has white in the wings, much more white in the tail, and a yellow base to the bill.
识别特征
It is a medium-sized bird, 54–58 cm (21–23 in) in length. With a body mass of 210 to 400 g (7.4 to 14.1 oz), it appears to be the largest hornbill of the relatively diminutive Tockus genus. The species is characterized by a white belly, black back, with white spots on the wings and white secondary flight feathers. The outer feathers of the long tail are also white. Females are smaller than males and can be recognized by their turquoise facial skin. The eyes are black and the beak is red.

Chihuahuan Raven
Corvus cryptoleucus
The raven of dry grasslands and desert scrub from the southwestern U.S. to central Mexico. Very similar to Common Raven, and sometimes best left unidentified. Chihuahuan is slightly smaller and more compact than Common, and tends to be found in more open habitats at lower elevations, not in mountains or forests (although Common can be found in low grasslands, too). Neck feathers are white at the base on Chihuahuan, instead of gray. Occurs in pairs or flocks, sometimes quite large, especially in winter. Gives a rather dry, crow-like squawk.
Chinchipe Spinetail
Synallaxis chinchipensis
Handsome spinetail restricted to the Marañon Valley in northwestern Peru. Note spotted breast sides, indistinct pale eyebrow, and chestnut wings and tail. Pairs stay fairly low in deciduous forest and scrub, often skulky and difficult to see. Listen for fast sputtering trills.
Nazca Booby
Sula granti
Large seabird, very similar to Masked Booby. Long and pointy on all ends: wings, tail, and bill. Adults mostly gleaming white with black flight feathers and face; note pinkish-orange (not yellow) bill to help separate from adult Masked. Young birds darker overall with brown head contrasting with white belly and dirty brown markings on underwings; very similar to young Masked or even adult Brown Booby. Found in the Pacific Ocean from Mexico to Peru where it feeds on fish; breeds on rocky islands, especially the Galapagos.
