Yucatan Wren
Campylorhynchus yucatanicus
Large, boldly marked wren of dry coastal scrub along north coast of the Yucatan Peninsula; no similar species in its range. Found in pairs or small groups, usually in areas with cactus plants. The upperparts are marked with a complex pattern of streaks and bars, the tail tipped whitish on the corners. The breast and belly have sparse dark spotting.
识别特征
The adult Yucatan wren is a small species about 18 centimetres (7 in) long. The face is whitish with a dark eye-stripe, and the crown is greyish brown. The upper parts are brown streaked with black and white, and the wings are brown and barred with dark brown and white. The tail is black barred with grey, with white tips to some of the outer feathers. The underparts are whitish with a dark cheek stripe and blackish spotting and barring.

分布与栖息地
The Yucatan wren is endemic to a coastal strip of the Yucatan peninsula. It can be found in arid areas with scrub, large cacti, and pastureland edges. Its breeding range is even more restricted to a strip about one kilometre wide, edging the mangrove forests which fringe the coast.

行为
The Yucatan wren is usually seen in pairs or small family groups and forages among the foliage and on the ground. Its diet is unknown.<p>The Yucatan wren starts nest-building activities in April, but eggs are laid in June. The nests are globular grass structures with side entrances. They are built a few metres off the ground in coastal scrub and the borders of the black mangrove (Avicennia germinans) forest, which thrives along the region's coasts. Clutch size averages three eggs, and both parents help rear the chicks. A third adult has been observed feeding the chicks occasionally, an example of cooperative breeding.

Stitchbird
Notiomystis cincta
A medium-sized songbird endemic to New Zealand, restricted to predator-free offshore islands and North Island mainland sanctuaries. Male has a black head with conspicuous white ear tufts and a white wingbar. Note the vibrant yellow neck and shoulder band. Females and juveniles only have the white wingbar. Curious by nature, confidently approaching people at close range. Despite this, the species can be difficult to spot due to its rapid movements. Both sexes give a high-pitched, single-noted “titch” warning call. Males also produce whistled calls of 2-3 notes. Females can be distinguished from bellbirds by lack of green coloration. Also note the constantly cocked tail and the white wing patches.
Long-billed Bernieria
Bernieria madagascariensis
Large, long-tailed, long-billed, dull-olive tetraka. Madagascar endemic that is found in rainforest, dry deciduous forest, and locally in spiny forest. Prefers the mid-story, and often joins mixed flocks with tetrakas and other birds. Song is a fairly musical phrase of up-and-down whistles. Call is a rough “trek-trak”. Separated from tetrakas by its larger size and its longer bill and tail. Doesn’t have the pale eye-ring of Spectacled Tetraka or the gray head of Gray-crowned Tetraka. Much more olive-colored than brush-warblers.
Orange Dove
Ptilinopus victor
A spectacular and unique dove. Male is vivid orange with peculiar hair-like feathers and bright yellow wingtips. Head is duller brown than body. Female is mostly green with a yellow undertail and a brownish face. She resembles female Golden and Velvet Doves, but those species do not overlap in range. Unique voice sounds much like a dripping tap from a distance, but up close more like someone clicking their thumb and finger together: a regular “drip drip drip.”
