The grey-headed bulbul (Brachypodius priocephalus) is a member of the bulbul family, Pycnonotidae. [1] [3] It is endemic to the Western Ghats in south-western India, and found from Goa south to Tamil Nadu at altitudes up to 1200m. It is found in dense reeds or thickets mainly near rivers and swampy areas inside forests. They have a distinctive call that reveals their presence inside dense vegetation where they are hard to spot.

The grey-headed bulbul was originally described by Thomas Jerdon under the name of Brachypus priocephalus. It was moved to Brachypodius poiocephalus by Edward Blyth, who erroneously "emended" the species epithet, with subsequent confusion in the literature. [4] [5] [6] [7] Formerly, some authorities placed this species within the genus Ixos and later Pycnonotus . [5] [2]

The genus Pycnonotus was found to be polyphyletic in recent molecular phylogeny studies and the species returned to Brachypodius. [3] [8] [9]

The common name 'grey-headed bulbul' is also used as an alternate name for the yellow-bellied bulbul.

Description

This bulbul is resident in moist broad-leaved evergreen forest with bamboo and dense undergrowth. Its plumage is olive-green, with a medium-grey on the crown head, nape and throat. The forehead is yellow-green. The back and wings are olive-green becoming lighter towards the vent. The rump has yellowing green feathers edged in black giving a barred appearance. The flanks are dark and grey edged. The undertail coverts are grey. The beak is greenish and grey while the legs are pinkish yellow. The iris is distinctly bluish white. The tail is grey on the central feathers (the shaft being black), the outer ones are black and are broadly tipped with grey. Both sexes are similar but juveniles have the head dark olive with the yellow on the forehead duller. (Length 143-152mm; head 33-35mm; tail 74-77mm) [10] [4] [11] The call is a sharp chraink. [10] The call is distinct in having a single syllable unlike those of the core genus Pycnonotus members. [10]

Behaviour and ecology

Found singly or in small groups, grey-headed bulbuls actively join mixed-species foraging flocks during the non-breeding season.

Breeding

Grey-headed bulbuls breed from January to June with a peak in April. The nest is a typical platform placed inside a low bush. They build their nest over a period of a week using vines, grasses or leaves. Many nests in a study in the Silent Valley National park were found to be made on saplings of Syzygium species or in reeds of Ochlandra travancorica . The typical clutch is one egg or sometimes two eggs that are incubated for 12 to 14 days. Eggs are sometimes destroyed and eaten by palm squirrels ( Funambulus tristriatus ). [12] The eggs are pale pink to lavender and flecked in red, more densely on the broad end. [13] Both parents take part in incubation and feeding. [14] The nestlings leave the nest after 11 to 13 days.

Feeding

The diet consists mainly of fruits (>65%) and invertebrates (>30%). Fruits include those of Symplocos cochinchinensis , Antidesma menasu , Clerodendrum viscosum , Syzygium cumini , Litsea floribunda , Maesa indica , Callicarpa tomentosa , Leea indica and Lantana camara . [15] [16]

<span class="mw-page-title-main">Bulbul</span> Family of birds

The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and bristlebills. The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean. There are 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas.

The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos.

The Wayanad laughingthrush is a species of laughingthrush in the family Leiothrichidae. It is endemic to the Western Ghats south of Goa in India. These laughingthrushes move in groups in dense forests, producing loud calls but tend to be hard to spot in the undergrowth. They have brown upperparts, a white throat, a broad black mask through the eye and a heavy bill with pale yellow on the lower mandible. Despite the name, derived from the Wayanad region, this species has a wider range than the four other south Indian species of laughingthrush that are restricted to the higher elevation hills.

<span class="mw-page-title-main">Flame-throated bulbul</span> Species of bird

The flame-throated bulbul is a member of the bulbul family of passerine birds and the state bird of Goa. It is found only in the forests of the Western Ghats in southern India. Formerly included as a subspecies of Pycnonotus flaviventris it has since been elevated to the status of a full species. They are olive-backed with yellow undersides, a triangular orange-red throat and a white iris that stands out against the contrasting black head. They are usually seen foraging in groups in the forest canopy for berries and small insects. They have a call often with two or three tinkling notes that can sound similar to those produced by the red-whiskered bulbul. The species has been referred to in the past by names such as ruby-throated bulbul and black-headed bulbul, but these are ambiguous and could apply to other species such as Rubigula flaviventris and R. dispar.
