Hypocolius
Hypocolius ampelinus
A slender, pale gray bird with a short bill and a long black-tipped tail. The male has a black face. This distinctive species occurs in arid scrub, desert, and nearby farmlands. Usually found in small flocks, often seen feeding on fruiting trees and bushes. Calls include short, squeaky wails and whistles.
Identification
The grey hypocolius is a slim bird with a long tail, slight crest and thick, short hook-tipped bill. Its shape and soft, satiny plumage resembles that of the waxwing. Birds are mainly a uniform grey or brownish-grey colour, with males having a black triangular mask around the eyes. They have white-tipped black primary wing feathers and a black terminal band on the tail. Adults are about 19–21 cm (7.5–8.3 in) in length.<p>The head feathers are raised when the bird is excited. They fly in a straight non-undulating style and when hopping in shrubbery, can appear like a babbler. The tarsus is short and sturdy with coarse scales. There are rictal bristles visible at the base of the bill and the nostrils are exposed, small and oval.
Taxonomy
The relationships of the species were formerly unclear. Earlier authors had suggested that they were related to the bulbuls or shrikes. They appear to be related to the waxwings, and at least one study based on molecular sequences suggests that it belongs to the same group. A 2019 study found them to be in a clade containing the palmchat (Dulidae), waxwings (Bombycillidae), silky-flycatchers (Ptiliogonatidae), hylocitrea (Hylocitreidae), and the extinct Hawaiian honeyeaters (Mohoidae), with Hypocoliidae being a sister group to the Mohoidae (with both diverging about 15-20 mya during the early-mid Miocene), and the clade containing Mohoidae and Hypocoliidae being sister to Hylocitreidae, which diverged slightly earlier in the Miocene.

Range and habitat
The grey hypocolius ranges through the Middle East, breeding in the Iraq, Iran, Afghanistan, Pakistan, Turkmenistan area, and wintering mostly near the Red Sea and Persian Gulf coasts of Arabia, including Bahrain. It is a vagrant to Turkey, Israel, Egypt and Oman. They are regular winter visitors to the Kutch and Jamnagar region of western India and vagrants have been noted as far south as Kihim near Bombay. It is found in woodland and scrub in arid and semiarid regions, especially river valleys near deserts, as well as in irrigated and cultivated areas with trees, sea costal area, palm groves and gardens.

Behavior
The grey hypocolius is a shy and unobtrusive, even cryptic, bird which will fly to thick cover when disturbed, where it will remain motionless until the perceived danger has passed. Its flight is strong and direct (without undulations). It will form flocks, especially in winter, and roost communally.<p>The breeding season is June or July in Arabia. The nest is cup shaped and deep lined with hair and fluff. The nest is often placed on the leaves of a date palm at a height of about 3 to 5 feet. Both the male and female take part in nest building. The clutch is four eggs. The eggs are leaden white with blotches. The incubation period is about 14–15 days.<p>Grey hypocoliuses forage quietly and methodically in foliage, through clusters of trees, palm groves and orchards, rarely coming to the ground. Though they may eat some insects, their main diet consists of fruits and berries, including Real mustard fruits, mulberries, figs and dates. In captivity they have been known to readily take bread.<p>The most common vocalization is a series of squealing descending notes or kleeeu whistles. Other calls include scolding chirps.
Conservation
Because the species has a large range, and because it does not meet the population size and decline criteria of the IUCN Red List, the conservation status is evaluated as being of "least concern". Because of its monotypic family status it is much sought after by birdwatchers.

Bare-shanked Screech-Owl
Megascops clarkii
Large for a screech-owl. Warm rufous-brown overall, brightest on face, which does not have a distinct black border like most other screech-owls. Coarsely marked on belly. Found in montane forests, where the best way to find it is by voice. Listen for the short series of hoots.
Streak-capped Spinetail
Cranioleuca hellmayri
Mostly brown arboreal spinetail with a black-streaked rufous crown and rufous wings and tail. Has a narrow white eyebrow, diffuse pale streaks on face, and slightly downcurved bill. Forages actively by hitching up branches and tree trunks, checking leaves and bromeliads. Often found with mixed-species flocks in humid forests, tall secondary forests, and forest borders. Quite vocal, the song an accelerating series of short, high notes; calls are a squeaky “CHIP-up.” Similar to Crested Spinetail but in Streak-capped note the contrasting rufous crown and white eyebrow. Endemic to the Sierra Nevada de Santa Marta and Sierra de Perija in Colombia and Venezuela.
Lewin's Honeyeater
Meliphaga lewinii
A medium-sized olive-gray honeyeater with a pale yellow cheek patch and a relatively stout bill. Cheek patch is often a crescent compared to the circular patch on Graceful Honeyeater and the oval path on Yellow-spotted Honeyeater. Adults have a bluish eye, while the similar Graceful Honeyeater has a blue-gray eye and Yellow-spotted Honeyeater has a brown eye. Listen for the rapid staccato machine-gun call of Lewin’s compared to the loud repeated whistles of the Yellow-spotted Honeyeater and the more simple, single note call of Graceful Honeyeater. Of the three easily confusable species, this is the only one found away from the tropics; it occurs in wetter forests and gardens all along the eastern coast of Australia.
