Chiriqui Quail-Dove
Zentrygon chiriquensis
Plump ground-dwelling dove, quite bright rufous overall compared with other quail-doves. Entire body is warm rufous, similar to Ruddy Quail-Dove, but note gray crown and black mustache line. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.

The male Chiriqui quail-dove is 27 to 31 cm (11 to 12 in) long and the female 26 to 32 cm (10 to 13 in). Adults weigh between 295 and 308 g (10.4 and 10.9 oz). The adult male has a slate gray crown that is paler on the forehead and darker on the nape. The rest of the face is buffy with a black malar stripe and a thin black line through the eye. The eye is brownish orange surrounded by bare red skin. The upperparts transition from chestnut on the shoulders through purplish on the upper back to olivaceous with a greenish gloss on the lower back. The chin is buffy white that darkens to reddish on the chest and sides and then lightens to cinnamon buff on the belly; the flanks are a darker cinnamon. Females are very similar, but their breast is usually darker. Juveniles have a brown crown and upperparts and the underparts have dull black bars.

Crimson Rosella
Platycercus elegans
Colorful rosella with blue cheek patches and highly variable plumage, occuring in crimson, yellow, and orange forms. Note diagnostic blue cheek regardless of form (the Green Rosella of Tasmania also has blue cheeks but the two species’ ranges do not normally overlap). Juvenile much greener than adult, attaining a blotched mixed plumage as they transition to adult. Found in a wide range of habitats in southeastern Australia. In many locations it is accustomed to humans and can be quite tame. Contact call is a familiar two-toned whistle.
Red-shouldered Blackbird
Agelaius assimilis
A mostly black inhabitant of swamps and marshes. The male has a telltale orange-red shoulder patch with pale yellow trim, which the female lacks. Both sexes of Tawny-shouldered Blackbird have a yellow-orange shoulder, though the shoulder color is sometimes only visible in flight. The Shiny Cowbird lacks a shoulder patch, is quite glossy, and has a shorter and stouter bill than Red-shouldered Blackbird. The call is a “chut” or “chut-chut” and song is a shrill “Shuh-reee-eee.”
Tawny Grassbird
Cincloramphus timoriensis
Large songbird, tawny with streaking above, paler below, with rich brown crown and long, graduated tail. In similar grassland and reedbed habitats, smaller Golden-headed Cisticola has much shorter tail, Little Grassbird is duller in plumage, and Australian Reed-Warbler has plain, unstreaked plumage. Calls often, with loud, grumpy churring calls and a longer call that starts “tick-tick-tick-tick” and ends with an explosive descending trill.
