Elegant Euphonia

A large, unusual bushshrike of Tanzania’s Uluguru Mountains with a huge bill, a black head, a green back, and yellow underparts. Found in the canopy of montane forest, usually in pairs. Most often detected by the distinctive and unusual voice, which consists of sliding whistles given in pairs, one lower and one higher, along with well-spaced ratcheting notes. These two vocalizations are usually synchronized as a duet by a pair. 

A tiny, long-tailed, thin-billed songbird. Soft blue-gray above and whitish below, with a thin white eyering. Breeding males have a black band across the forehead. Forages actively for insects, often actively twitching its long tail. Can be found singly or in pairs, sometimes with mixed flocks of other songbirds, especially during migration. Two populations: Eastern birds breed in deciduous woodlands, often near water; western birds typically breed in drier, brushier habitats. Winters from the southern U.S. to northern Central America. Compare with Black-tailed Gnatcatcher, especially the tail pattern from below: Blue-gray is mostly white, with very limited black. Also very similar to Black-capped Gnatcatcher on the wintering grounds in West Mexico; Blue-gray has a higher-pitched call.

Large, spectacular, and basically unmistakable penguin that is rarely seen away from well-known colony sites. The long and stout bill distinguishes King from the even larger but shorter-billed Emperor Penguin, which is a true Antarctic species, rarely seen far from ice. Also note the golden neck patches (can fade to whitish on immatures) and pink bill base (bill starts out black on immature). Breeding season requires more than a year, so birds can be seen year-round at colonies.
