分布与栖息地
The dusky-backed jacamar is found in Panama's Darién Province and the adjoining and nearby northern Chocó, northern Antioquia, and southern Córdoba Departments of Colombia. There is also an isolated population in northern Bolívar Department, Colombia, that at one time was thought to be a subspecies. It inhabits humid primary and secondary forest. It is found in edges, such as by clearings and along streams, rather than the forest interior. In elevation it ranges up to 700 m (2,300 ft).

行为
The dusky-backed jacamar preys on a variety of flying insects that it catches by flying from a perch. It often perches and hunts in pairs or small family groups.<p>Though the dusky-backed jacamar is assumed to nest in burrows in earth banks, there is no documentation of its breeding phenology. Birds in breeding condition were noted during January and February in Colombia.<p>The dusky-backed jacamar has a complex song [1]. Its call is described as an "upwardly inflected 'sweet' or 'feet'...sometimes expanded to...a longer series" [2].

Gray Treepie
Dendrocitta formosae
A long-tailed corvid found in lowland to submontane forests, parks, and gardens. Adults have black face, gray nape, brown back, pale belly, dark wings (with white patch visible in flight), orange undertail coverts, and long, black-tipped gray tail. Raucous, with a diverse repertoire; squawks and chatters loudly, but also whistles tunefully. Social, often in pairs or flocks, sometimes with other species. Forages primarily in trees, but also descends to the ground occasionally.

Arctic Loon
Gavia arctica
A medium-sized loon, widespread across Eurasia but rare and local in North America. All plumages have white “hip patch” usually visible on swimming birds. Breeding plumage striking with gray head, white-checkered back, and bold white lines on sides of neck. Nonbreeding plumage has fairly extensive white on face and an even border between gray and white on the neck. Smaller and sleeker than Common Loon. Larger and darker than Red-throated Loon, with straight, dagger-like bill. Especially similar to Pacific Loon, which overlaps mainly from Alaska to Japan; rarely further south along the West Coast of North America. Arctic is subtly larger-billed and often holds its head at a slight upward angle. In breeding plumage, Arctic has a darker gray nape and bolder white stripes on the neck than Pacific. Breeds on lakes in the taiga and tundra. Winters mainly on coastal bays and inshore waters; singles rarely occur on reservoirs and larger lakes.

Scarlet Macaw
Ara macao
Spectacular, huge, and long-tailed parrot, wiped out from most areas by capture for the pet trade; attempts at reintroduction are taking place in some protected areas. Found very locally in lowland rainforest and adjacent semiopen areas with big trees; usually in pairs. Unmistakable, bright scarlet red overall with big yellow wing patches and mostly blue wings and rump. Calls are deep, throaty roars that carry long distances.
