Gray-headed Kite
Leptodon cayanensis
Scarce hawk of lowland tropical forest. Perches mainly in the canopy, at times giving a long, laughing call. In flight, the wingbeats are loose and floppy. When soaring the wings are held rather level. Adult is distinctive, with a soft gray head, dark eyes (no yellow in the face, unlike most hawks), and rather small grayish feet. Immature has several plumage types, all with 2–3 broad, pale-gray tail bands. One type has a dark brown head and upperparts and whitish underparts with dark streaking; another has a white head and underparts with a small dark cap.
Identification
The gray-headed kite is 46–53 cm in length and weighs 410-605 g. The adult has a grey head, black upperparts, white underparts, and a black tail with two or three white bars. The bill is blue and the legs grey. The flight is a deliberate flap-flap-glide.<p>Immature birds have three colour morphs; the light phase is similar to the adult, but has a white head and neck, with a black crown and eyestripe, black bill and yellow legs, closely resembling the Black-and-white hawk-eagle (Spizaetus melanoleucus). The rufous phase has a reddish neck with a white throat, black malar stripes and a black, long crest closely resembling the adult Ornate hawk-eagle (Spizaetus ornatus). The dark phase has a blackish head, neck and upper parts, and dark-streaked buff underparts closely resembling the Black hawk-eagle (Spizaetus tyrannus). The sophistication in the mimicry of these juveniles is remarkable and has only been described a few times.

Behavior
The gray-headed kite feeds mainly on reptiles such as arboreal geckos, other lizards and snakes, but also takes frogs, molluscs and large insects (including larvae and combs of hornets, wasps and bees). It also feeds on eggs, young or injured birds. It usually sits on an open high perch from which it swoops on its prey. The call is a mewling keow. The nest is made of sticks lined with grass and is built high in a tree. The clutch is one or two white eggs, purplish at one end and spotted brown.

Coastal Miner
Geositta peruviana
A pale terrestrial bird found only in coastal deserts of Peru. It is pale brownish-gray and lacks strong field marks. Very similar to Grayish Miner; Coastal Miner has a wing stripe, though this is only evident in flight. The two species mostly separate out by range, with Coastal Miner favoring the flat coastal plain and Grayish Miner preferring rocky slopes of hills and mountains. Coastal Miner is also similar to Short-tailed Field Tyrant, but lacks distinct wingbars and rump patch, and has a longer tail. Solitary, usually seen running through barren, sandy areas. Occasionally flies up to perch on a rock or bush, and also performs flight displays.
Cordillera Azul Antbird
Myrmoderus eowilsoni
This beautiful antbird is one of the most spectacular ornithological finds in recent years. It was discovered in 2016, and named for the remote mountain range in northern Peru where it is found. The male has black underparts and wings, chestnut upperparts, white eyebrows, and buffy wingbars. The female has chestnut underparts and a white throat, giving her a masked appearance. Inhabits cloud forest understory, where it is usually seen walking slowly on the ground. Song is a piping “see you see me.”
Emperor Goose
Anser canagicus
Stocky goose that inhabits rocky coastlines, lagoons, and tidal flats. Striking white head, black throat, and petite pink bill. Blue-gray body with intricate black-and white bars, a white tail, and bright orange legs. Face sometimes stained orangish-brown. Juvenile has a gray head, but still shows white tail. Breeds on marshy tundra and winters in small flocks on coastal waters. Rarely seen outside Alaska.
