Western Yellow Wagtail
Motacilla flava
Widespread wagtail, favoring wet meadows, marshland, grassy and muddy lakeshores. Occurs in fields and often near livestock during migration. Like other wagtails, walks on ground and pumps its long, white-sided tail up and down. Plumage highly variable, but breeding male wholly bright yellow below, with greenish back. Male head pattern varies regionally: in U.K. has greenish head with yellow eyebrow; in northern Europe head slaty gray overall; in central and southwest Europe head blue-gray with white eyebrow; striking white-headed birds in Mongolia and northwestern China. Individuals of several subspecies may winter together. Female and nonbreeding plumages drabber and paler, with ghosting of male patterns. Songs and calls vary between subspecies, but most give some form of buzzy “dzeerdzeer” or downslurrd “tzree.”
Identification
The western yellow wagtail (Motacilla flava) is a small passerine bird in the wagtail family Motacillidae, which also includes the pipits and longclaws. This species breeds in much of temperate Europe and Asia. Most populations are migratory, moving south to tropical Africa and southern Asia for the winter; the small population breeding in Egypt is however resident there. It is a slender 15–16 cm long bird, with the characteristic long, constantly wagging tail of its genus. It is the shortest tailed of the European wagtails. The breeding adult male is basically olive above and yellow below. In other plumages, particularly in juveniles, the yellow may be diluted to whitish. The heads of breeding males come in a variety of colours and patterns depending on subspecies. The call is a high-pitched jeet. This insectivorous bird inhabits open country near water, such as wet meadows. It nests in tussocks, laying 4–8 speckled eggs.
Taxonomy
Motacilla is the Latin name for the wagtail; although actually a diminutive of motare, " to move about", from medieval times it led to the misunderstanding of cilla as "tail". The specific flava is Latin for golden-yellow.<p>This species' systematics and phylogeny is extremely confusing. Dozens of subspecies have been described at one time or another, and some 15-20 are currently considered valid depending on which author reviews them. In addition, the citrine wagtail (M. citreola) forms a cryptic species complex with this bird; both taxa as conventionally delimited are paraphyletic in respect to each other. The populations of the Beringian region are sometimes separated as eastern yellow wagtail (M. tschutschensis).<p>Colouration refers to males except when noted.<p>The nominate blue-headed wagtail and yellow wagtail form a narrow hybrid zone in northern France. Birds from this zone vary in appearance, but one type, which resembles nominate blue-headed wagtail (except that the blue tones to the head are paler and more mauve and the white of the head is more extensive, particularly on the throat, ear-coverts, and supercilium) is colloquially referred to as Channel wagtail.

Ashy Tailorbird
Orthotomus ruficeps
Small, active, gray bird with a long bill and a dark-tipped, frequently-cocked-up tail. Orange face diagnostic within its range. Males are gray-throated, whereas females have white throats. Common in mangroves, but also frequently encountered in edge, open forest, and other secondary growth. Generally quite tolerant of human habitation and can be found in parks and on roadsides. Song is crisp and bright: a repeated “twoo-lip, twoo-lip” or “chip-wee, chip-wee”. Calls are variable but frequently sound like isolated fragments of song.
Pale-bellied Mourner
Rhytipterna immunda
Medium-sized, dull flycatcher; resembles a Myiarchus but has smaller bill, rounder head, and little contrast between breast and belly. Locally distributed and poorly known; found in seasonally inundated and scrub woodlands on weathered white sands. Inconspicuous and best located by voice; behaves sluggishly, sallying to foliage for insects; also eats fruit. May be found alone or in loose association with other species. Distinctive voice is a rich, slurred whistle, Schiffornis-like in quality and unlike any other species in habitat.
Great Thrush
Turdus fuscater
True to its name, Great Thrush is noticeably large, almost recalling a jay rather than a thrush. Brown overall, varying across range from dark blackish to paler grayish-brown. Note orange bill and legs and yellow eyering (males only). Common and conspicuous in highlands from 2,000–4,000 m. Found in open habitats including forest edges, gardens, towns, and cities, where it is often bold and easy to see. Compare with Chiguanco Thrush, which overlaps in some areas. Great Thrush is larger, darker, and males have yellow eyering.
