Spotted Tanager

Small songbird with bright yellowish upperparts and white “goggles.” Most subspecies have gray underparts; subspecies “unicus” of Sumbawa and Flores has a yellow belly. Compare with other white-eyes in various parts of their range; note present species combination of dark iris and yellow back. Inhabits a wide range of different wooded habitats across its range, including coastal scrub, mangroves, inland forests, and forest edge. Forages actively in small to medium-sized flocks, sometimes mixing with other species. Can be quite common on small islands. Twittering song is bright but unremarkable. Most frequently given call is a somewhat variable high-pitched, descending “djee.”

A large duck, generally common and familiar within its extensive range. Males are distinctive with iridescent green head, yellow bill, chestnut breast, and gray body. Females are mottled brown with orange and black splotches on the bill. Found anywhere with water, including city parks, backyard creeks, and various wetland habitats. Often in flocks, and frequently mixes with other duck species. In North America, females can be tricky to distinguish from American Black Duck, Mottled Duck, and Mexican Duck where ranges overlap. Those species are all darker-bodied than Mallard. A good view of the wing can be helpful, too: white wingbars on the leading and trailing edges of the blue wing patch are bolder on Mallard. Frequently hybridizes with those species, which can be even more confusing. Any bird with extensive white in the tail or curled feathers above the tail has some Mallard genes.

A large, heavy-billed loon. Common and widespread in North America; somewhat less common and more local in Europe. Breeding adults have gorgeous black-and-white patterning; especially note fully black head with iridescent sheen and boldly checkered back. Nonbreeding plumage is plainer gray above and white below; note the jagged border between gray and white on the neck. Heavy bill is usually held straight (compare with Yellow-billed Loon). Breeds on lakes and ponds in the boreal forest. Listen for their haunting, yodeling vocalizations. In winter, mostly found on nearshore ocean waters and sheltered bays, singly or in loose flocks.
