Yucatan Nightjar
Antrostomus badius
Fairly large dark nightjar of woodland, edge, and adjacent clearings in the Yucatan Peninsula. Hunts mainly from perches at forest edge, sometimes even on fence posts in rather open areas. Cryptic plumage similar to other nightjars, but face and throat not as plain as Yucatan Poorwill, and male has extensive flashy white in his tail; female has narrower, buffy-white tail corners. Multi-syllable song very different from Yucatan Poorwill and Pauraque, and suggests Chuck-Will’s-Widow of southeastern US.

The Yucatan nightjar is 24 to 25.5 cm (9.4 to 10 in) long. One male weighed 65.5 g (2.3 oz) and three females 51.2 to 64.3 g (1.8 to 2.3 oz). The male's upperparts are grayish brown. The crown has blackish brown spots and grayish white speckles, and the back and rump have buff and cinnamon speckles and broad blackish brown streaks. It has a broad tawny or buff collar on the nape and the sides of the neck. The tail is brown with faint tawny bars; the three outermost pairs of feathers have wide white tips and the innermost pair grayish brown mottling on the tips. The wings are brown to grayish brown with tawny spots and bars. The face is tawny with blackish brown speckles. The chin and throat are dark brown with cinnamon bars and a narrow white band below the latter. The breast is brown with buff and cinnamon speckles, and the belly and flanks are blackish brown with cinnamon speckles, brown bars, and many white spots. The female is similar to the male but the pale tips of the outer tail feathers are much smaller and buff, not white.
分类信息
The Yucatan nightjar was for many years classified in genus Caprimulgus but was later restored to its original genus Antrostomus. It and the tawny-collared nightjar (A. salvini) were for a time considered subspecies of the silky-tailed nightjar (A. sericocaudatus). The Yucatan nightjar is monotypic.

分布与栖息地
The Yucatan nightjar is a year-round resident of Mexico's Yucatán Peninsula and Cozumel off its coast. It is a nonbreeding visitor to Belize and northwestern Honduras, and there are a few reports from northern Guatemala in that season as well. It inhabits "scrub and brushy woodland [and] forest edge".

行为
The Yucatan nightjar is nocturnal. It hunts for flying insects by sallying from a perch and possibly also from the ground.<p>The Yucatan nightjar's breeding season has not been defined. The clutch size is two eggs, probably laid directly on the ground with no nest as is common among nightjars.<p>The Yucatan nightjar's song is "a loud, clear puc ree-u-reeeu' or pc weeu wee-weeeu. It is sung from a hidden perch in a bush or tree, mostly from February through August. It also makes a "hard, hollow clucking, k-lok k-lok ... or p-tok ...."

Brambling
Fringilla montifringilla
Distinctive and handsome orange-breasted finch. Note black head of males (solid in breeding season, patchy in non-breeding) and gray-and-brown head of females. Complex wing patterns and white rump patches create a wondrous show when a flock rises up in flight. Breeds in northern woodlands, especially in and around birches; winters in varied wooded habitats (especially with beech trees), semiopen country, and farmland with hedges; sometimes visits gardens and parks with feeders or fruiting trees. Song is surprising and almost ugly for such a well-marked finch, a strange ringing buzz: “eerRRRRNnnn.” Gives a rising “qweee”, a higher-pitchd “tsi, tsi”, and various twittering and nasal flock calls.
Amazonian Elaenia
Myiopagis cinerea
Small flycatcher of rainforest canopy. Gray male is fairly distinctive with his black wings and bold, white wingbars. Female is clad in shades of yellow and olive and has yellowish wingbars. She is very similar to Forest Elaenia and Yellow-crowned Elaenia, but has paler and cleaner underparts, and usually stays higher up in the trees. Also very similar to Gray-headed Elaenia, but note its more northern range. In areas where their ranges meet, identification may have to be confirmed by voice, though Amazonian Elaenia usually shows a dark (not white or yellow) eye. Typical song is a rapid, descending trill. Pairs are typically seen very high in the forest, and often follow mixed species flocks.
Brown-headed Honeyeater
Melithreptus brevirostris
Small honeyeater with brown cap. Primarily gray-brown with olive back and lighter underparts. Eye patch and band leading from the eye to back of the head are cream-colored. Juveniles have pale blue coloration around the eye and a yellow bill. Take care to separate from juvenile White-naped Honeyeater, which lacks the pale half collar around the side of the neck. The plumage of this species varies geographically. Common in eucalypt forests, where it is usually very vocal and active. Forages in small groups.
