Lined Quail-Dove
Zentrygon linearis
Plump ground-dwelling dove. Large for a quail-dove with buffy face, gray crown, scaly neck, and white throat. Body mostly brownish. Sexes alike. Very similar to White-throated Quail-Dove but no range overlap and typically occurs at slightly lower elevations. Found in the foothills and subtropical zone up to 2,500 m. Usually walks on the ground unless flushed into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk. Listen for low-pitched “coo” notes.
识别特征
The lined quail-dove is 27 to 29 cm (11 to 11 in) long and weighs 230 to 284 g (8.1 to 10.0 oz). Adult males have a pinkish buff forehead that darkens to purplish brown on the crown. There is a pale gray arc from the eye to the nape and the cheeks are buffy. A thin dark stripe goes from the bill through the eye and another in the malar area. The mantle is reddish purple and the rest of the upperparts reddish brown with purple or bronze-green iridescence on the hindneck. Loose feathers on the sides of the neck give the impression of dark furrows. The breast is pale gray to brownish gray and its sides are purple. The belly and flanks are buffy fawn. The eye can be various shades of yellow to orange-red; it has a narrow red ring and is surrounded by bare blue skin. The legs and feet are red. Females are almost identical to males with the addition of a brownish tinge to the gray breast. Juveniles have overall redder plumage with numerous brown and blackish bars.
分类信息
The lined quail-dove's taxonomic history is complex. It was originally placed in genus Geotrygon. It, the white-faced quail-dove (Z. albifacies), and the Chiriqui quail-dove (Z. chiriquensis) have been treated as a superspecies or even as conspecific. It has two subspecies, the nominate Zentrygon linearis linearis and A. l. trinitatis. The population of the nominate in Colombia's Sierra Nevada de Santa Marta has been proposed as a separate subspecies. A. l. trinitatis has been treated as a separate species by some authors, and the mainland population of it has been proposed to be split as separate subspecies.

分布与栖息地
The nominate subspecies of lined quail-dove is found in Colombia's Sierra Nevada de Santa Marta, the Andes of Colombia and Venezuela, and Venezuelan coastal mountain ranges. A. l. trinitatis is found in Venezuela's northern Monagas and Sucre states and Trinidad and Tobago. It inhabits tropical lowland and evergreen montane forests from sea level to 2,500 m (8,200 ft).

行为
The lined quail-dove forages singly or in pairs, feeding on seeds on the forest floor.<p>The lined quail-dove's breeding season in Colombia spans at least from April to October and begins earlier in Trinidad and Tobago. One described nest was a deep cup of small twigs lined with dead leaves, placed in the fork of a tree 3.7 m (12 ft) above the ground. It contained two eggs.<p>The lined quail-dove's song is "a single monotonous low-pitched note 'whoOOo', with highest amplitude in the middle." Two birds will sing at the same time at slightly different pitches.

Prairie Warbler
Setophaga discolor
Small warbler, yellow overall with black streaks on sides and unique face pattern. Upperparts are duller olive. Reddish streaks on back are distinctive, but can be difficult to see or absent on immatures. Long tail is often pumped up and down, but not as consistently as Palm Warbler. Forages for insects in a range of shrubby habitats, from cedar-studded fields to regenerating woods to mangroves in Florida. Winters in Florida and the Caribbean.
Black-capped Tinamou
Crypturellus atrocapillus
Subtly colorful tinamou of dense habitats in the lowlands and Andean foothills. Almost exclusively found in bamboo thickets, but also occasionally found in dense riverside vegetation and secondary growth, including around agriculture. Rarely seen, but frequently heard throughout the day; it usually gives about one call note per minute, a springy “bwow”. The most helpful visual field mark is its bright orange legs; it also has a black or dark gray cap, and brown plumage with cold gray head and neck, and reddish orange throat.
Crimson-backed Flameback
Chrysocolaptes stricklandi
Large, spectacular woodpecker with crimson upperparts, black-scaled pale underparts, and a crested head. Males have a red crest, females a black crest with fine white markings. Endemic to Sri Lanka. Typically in pairs, in the understory of forests and woodlands, where it regularly joins mixed species flocks; can also occasionally be found in disturbed areas or home gardens. Note the pale ivory colored bill, and lack of a prominent white eyebrow, unlike the similar Red-backed Flameback. Also note a distinctive elliptical marking on the face below the eye, which distinguishes this flameback from all other flamebacks on Sri Lanka. Frequently given call is a rapid, fast-paced, high-pitched trill, usually getting quieter and decelerating at the end. A fast-paced, descending drum is also given regularly; both the call and drum are different from that of the more common Red-backed Flameback.
