Little Tinamou
Crypturellus soui
Furtive, almost tailless small game bird that lives on the ground in humid tropical lowlands. Favors forest edge and dense secondary growth rather than forest interior. When disturbed runs rather than flies. Very rarely seen (sometimes crosses quiet roads or trails), but tremulous whistles are often heard, especially early and late in the day. Plumage is dark brownish overall with grayer head and whitish throat.
Identification
The little tinamou is approximately 22 to 24 cm (8.7–9.4 in) long and weighs 220 g (7.8 oz). Although it looks similar to other ground-dwelling birds like quail and grouse, it is unrelated to those groups. It has an unbarred sooty-brown plumage which transitions to grey on the head. The foreneck is whitish. While the underside of both male and female is cinnamon buff, the female is a lighter shade. The legs can be grey, olive, or yellow. Both male and female are almost tailess.
Taxonomy
The little tinamou is one of 21 species in the genus Crypturellus, the most species-rich genus of tinamous. All tinamous are in the family Tinamidae, and in the larger scheme are also palaeognaths, a group that includes the more widely known flightless ratites such as ostriches and emus. Unlike the ratites, though, tinamous can fly, although in general they are not strong fliers. All palaeognaths evolved from flying ancestors.

Range and habitat

Behavior
Little tinamou are shy, secretive, and pair-solitary animals. Despite their abundance, they are rarely sighted. In the field, they are detected by sound more often than sight. The whistle call is a soft, descending whinny (also a series of single notes, tempo increasing at end) produced by both sexes. They eat seeds, berries, and some insects. They can fly but will run unless flight is necessary. They are highly territorial and will attack when encroached upon if the intruding bird is not their mate. There is evidence that they will maintain the same territory for years.<p>The breeding season of the little tinamou ranges from May to October. Nests are a small depression in forest floor, sometimes lined with a few leaves at the base of a tree or in dense brush. Females perform courtship behavior and eggs are incubated by males. Male nest attendance is strong, up to 14 days without leaving the nest in one study. They typically lay two glossy dark-purple eggs (up to three have been observed). The size of the egg is approximately 32 to 41 mm (1.3–1.6 in). Young are precocial, and begin pecking the ground on the first day. They can run almost as soon as they hatch. By weeks 3-4 they are capable of full flight. Egg laying begins at one year old.
Conservation
The IUCN list the little tinamou as Least Concern, with an occurrence range of 9,500,000 km2 (3,700,000 sq mi).

Purple Sandpiper
Calidris maritima
Plump, rock-loving shorebird with slightly droopy bill. Most often seen in nonbreeding plumage, which is fairly dark gray with spotted underparts. Namesake purple sheen (mostly on back, scapulars, and tertials) only visible at close distance in good light. Legs and base of bill usually bright orange. Messy-looking breeding plumage is darker and more heavily marked, with limited rusty tones on upperparts. Largely inaccessible breeding range on high Arctic tundra; most often seen in northern Europe, Spitsbergen, and Iceland. Winters at slightly lower latitudes, regularly south to the mid-Atlantic region in North America and the Iberian Peninsula in Europe; found in flocks on rocky coastlines and jetties pounded by heavy surf.
Central Melanesian Cicadabird
Edolisoma erythropygium
Small cuckooshrike with a restricted range, found only on the Solomon Islands, as well as a couple small islands off of New Ireland. Males are mainly gray with black on the face, wing, and tail. Distinctive female is mostly rufous-brown, with buffy underparts. There is geographical variation, with females unbarred in most of the range, but showing barred underparts in some places. Found singly or in pairs in forest and forest edge habitats at low and middle elevations. Vocalizations poorly known, but include a long series of “chyap” notes.
Dugand's Antwren
Herpsilochmus dugandi
Handsome antwren found in the canopy of lowland rainforest in eastern Ecuador, northeastern Peru, and southern Colombia. Male is gray with black crown, eye-stripe, and upper tail; wings are black with white bars and tail has white edges. Female is similar but with a brown crown and buffy or yellowish wash on breast. Compared to Ancient Antwren, male Dugand’s lacks yellow on underparts, and female has a brown crown. Usually seen with mixed-species flocks very high in the trees. More easily seen from a canopy tower or walkway if one is available. Song is a fast, accelerating series of dry “chup” notes.
