Velvet-fronted Nuthatch
Sitta frontalis
One of the few nuthatches to break the general neutral color scheme of the family, this stunner can be quite common in lowland and foothill evergreen forests. Aquamarine upperparts, crimson bill, and black patch on the forehead make this active little species unmistakable. Forages by creeping along trunks and branches, often upside down. Often moves in groups, frequently as a member of mixed-species flocks. Song is a high-pitched chittering trill; calls like isolated fragments of song.
Identification
The velvet-fronted nuthatch has the typical nuthatch shape, short tail and powerful bill and feet. It is 12.5 cm long. It is violet-blue above, with lavender cheeks, beige underparts, yellow eyes, and a whitish throat. The iris is distinctly pale and yellow. The bill is red, and there is a black patch on the forehead and lores which is well developed in adults and less so in younger birds. Young birds have a dark beak and dark tips to the undertail coverts. Adult males can be told apart by the black superciliary stripe that runs above the eye and over the head, towards the nape.<p>Females lack the supercilium and have a warmer underpart colour. Juveniles are duller versions of the adult lacking the black frontal band. There populations differ in shade and size and the distribution of white on the throat.
Taxonomy
Velvet-fronted nuthatches are closely related to Sitta solangiae, Sitta azurea and Sitta oenochlamys and some authors have placed them in a separate genus Oenositta (proposed by H.E. Wolters in 1979) which would be inappropriate as the clade, although distinct in morphology, is nested within other Sitta species. The complex includes numerous forms which have had a confusing history, for instance oenochlamys has been treated as a subspecies of frontalis in the past. The species was first described validly by Swainson who also created the genus Dendrophila in which he initially placed the species. Hodgson had however used the name Dendrophila for a species of partridge. Swainson used the species name given by Horsfield who had named the bird as Orthorynchus frontalis but Horsfield published only in 1821 giving priority to Swainson as the author.<p>About five populations are widely recognized as subspecies but some may be treated as phylogenetic species:<p>The use of ectoparasites such as Brueelia as a proxy to unravel the phylogeny of the species is unreliable as the nuthatch shares the same Brueelia species with flycatchers (Rhipidura and Ficedula), possibly because these parasites are phoretic, travelling across hosts via blowflies.

Range and habitat
The velvet-fronted nuthatch is a resident breeder of all types of forests from deciduous to evergreen forest. In the Sunderbans, they are found in Sonneratia mangrove forests. They also live within secondary forest and make use of the shade trees in south Indian coffee plantations.<p>Like other nuthatches they have strongly curved claws that allow them to climb down vertical tree trunks, unlike species such as woodpeckers that only work their way upwards. It moves jerkily up and down or around tree branches and trunks. It is an active feeder on insects and spiders, gleaned on the bark of the trunk and branches, and may be found in mixed feeding flocks with other passerines. The insects they disturb are sometimes taken by the racket-tailed drongo in Sri Lanka.<p>This is a noisy bird, often located by its repeated “sit-sit-sit” call.<p>Adults go through a complete postnuptial moult that begins at the end of June in northern India.<p>Plasmodium parasites including Haemoproteus have been detected in their blood. Feather mites of the genus Neodectes are found on the species.

Other Birds
Downy Woodpecker
Dryobates pubescens
Tiny woodpecker, common and widespread across much of North America. Black-and-white plumage is nearly identical to the larger Hairy Woodpecker. Focus on the bill: Downy has a very short bill, much shorter than the length of the head. Also note the small black markings on the white outer tail feathers. Pacific population has smaller white spots on the wing and a grayer body than Eastern birds. Occurs in any wooded habitat, though western birds are more restricted to riparian areas. Often forages on smaller branches than Hairy Woodpecker. Familiar visitor to backyard feeders, especially fond of suet. Calls include a soft “pik!” and descending rattle, weaker than Hairy Woodpecker.
Black-hooded Antshrike
Thamnophilus bridgesi
Antshrikes have large, flat heads and large, hooked bills; they often angle their tails downward, below the line of the body. Male Black-hooded is mostly black with a slightly paler belly; note small white spots on the shoulder. The female is paler gray overall with whitish streaking on the head and breast. Most often seen in pairs in the understory of forest and edges. Follows mixed flocks. Listen for accelerating chuckle with a longer raspy note at the end.
Scarlet Minivet
Pericrocotus speciosus
Brilliantly-colored forest bird, typically encountered in flocks. Coloration varies significantly throughout wide distribution, with males ranging from black-and-crimson (most of mainland Asia) to black-and-yellow (southern Philippines) and black-and-orange (Java and Bali). Females are predominantly gray-and-yellow, but southern Philippine and western Indonesian birds are black-and-yellow. In all subspecies, note colored “blotches” on the wings (other minivets have cleaner wing patterns) and female’s yellow forehead. Gives high whistled “wheeep” notes, often when flying over the treetops.
