Arabian Grosbeak
Rhynchostruthus percivali
Handsome chunky gray-brown finch with a massive dark bill. Brown hood, white ear-patches, and brightly contrasting golden stripes in the dark wings and tail make this an easily recognizable species. Female has a less well-defined hood than the male, and less yellow in the tail. Juvenile is buffier (including ear-patches) and more streaky. An uncommon resident of woodland, dry scrubby rocky terrain, slopes and river beds, restricted to the southern Arabian Peninsula. Typically forages singly, in pairs, or in groups of up to 30, either on the ground, or in trees where they occasionally dangle by their feet like parrots. Song is a pleasant rolling series of sweet notes, with an almost thrush-like quality. Call a quick whip-like “weet.”
识别特征
The males are grey-brown overall with a black bill. The head is brown, with a dark grey mask and white cheeks, and it has large, bright yellow patches on the wings and tail. The females are similar to the males though somewhat duller, and the juveniles are rather streaky and lack the adults' distinctive head pattern.

行为
The Arabian Golden-winged Grosbeak is typically found between 1,060 and 2,800 metres (3,480 and 9,190 ft) ASL in forested wadis and areas of scrub. Its range encompasses Dhofar in Oman, the Mahra of eastern Yemen, and the mountains of northern Yemen to Saudi Arabia. It ranges as far north as Al Hara near Ta'if, where one or two birds were seen on April 26–27, 1996.<p>In southwestern Saudi Arabia it is resident in relict East African Juniper (Juniperus procera) forests. In Yemen it has been recorded in spurge (Euphorbia) scrub and woodland of acacias (Acacia) and junipers (Juniperus), while in the wooded Mahrah it is primarily found in Anogeissus/Commiphora woodland. The fruits of juniper, acacia and spurge species appear to form the bulk of its diet.<p>It appears to be present in low densities throughout its range. The population is estimated at around 9000 individuals, but it is becoming rare due to habitat destruction. Therefore, when it was first evaluated as a distinct species for the 2008 IUCN Red List, it was categorized as a Near Threatened species.

Bearded Barbet
Pogonornis dubius
Large, colorful barbet with a huge ivory-colored bill. Note the red underparts with a thick black bar across the middle. Found in a variety of habitats, including moist and dry savanna, woodland, gardens, and secondary growth, often in the vicinity of figs and other fruiting trees. Most often in pairs or small groups. The call is a very rough, explosive “rwauk,” often given in a slow series. Similar to Double-toothed Barbet, but separated by the black chest band and the lack of a red bar on the shoulder.
Blue-throated Mountain-gem
Lampornis clemenciae
Very large for a hummingbird; size alone separates from many other species. Males and females similar: gray below, dusky-greenish back, brown rump, and large dark tail with prominent white corners. Also note white eyebrow and short white mustache stripe. Male has bright blue throat patch, difficult to see unless the light hits it just right. Uncommon in canyons and mountains with mixed pine-oak forests, primarily in Mexico but barely extending into the U.S. Very similar to Amethyst-throated Mountain-gem, especially if you can’t see the throat color. Blue-throated is slightly larger and paler overall with larger white (not gray) tips on the tail feathers; females are plainer, lacking the buffy tones of Amethyst-throated. Also compare with Rivoli’s Hummingbird, especially females; Blue-throated is shorter-billed and plainer (less speckled) on the underparts.
Puerto Rican Euphonia
Chlorophonia sclateri
Endemic to Puerto Rico. A brilliantly colored, tiny, and active species of dense woodlands where it feeds at middle to upper levels, primarily on mistletoe berries. Sometimes joins mixed flocks. Easy to miss despite bright colors and flitting movements. Note small size, short tail, and small (though rather thick) bill. Male has a blue helmet, yellow underparts (including the throat), and a dark mask. Female is olive-green overall; note distinctive blue helmet and small yellowish forehead patch. Calls include a lively “beep” given singly or in series, a rapid “whip-ip,” a rough “djip,” and a plaintive “wheee.” Song is a rapid jumble of tinkling, squeaky, and whistled notes.
