The yellow-throated bulbul (Pycnonotus xantholaemus) is a species of songbird in the bulbul family of passerine birds. The species is endemic to southern peninsular India. They are found on scrub habitats on steep, rocky hills many of which are threatened by granite quarrying. It is confusable only with the white-browed bulbul with which its range overlaps but is distinctively yellow on the head and throat apart from the yellow vent. The calls of this species are very similar to that of the white-browed bulbul.

Taxonomy and systematics

The yellow-throated bulbul was originally described by Thomas Jerdon in the genus Brachypus (a synonym for Pycnonotus), and later re-classified it in the genus Ixos . [4] It has since been re-classified to the genus Pycnonotus. The alternate name yellow-eared bulbul should not be confused with the species of that name, Pycnonotus penicillatus . The name 'yellow-throated bulbul' is also used as an alternate name for Falkenstein's greenbul.

Description

This uncrested species of bulbul is olive grey above with a yellow throat, undertail coverts and tail tips. The head is plain while the breast and belly have a grey wash. The closest resembling species is the white-browed bulbul but this has a supercilium and lacks the yellow throat. Males and females are similar in plumage. [5]

Distribution and habitat

The habitat of the species is rocky, scrub covered hills mostly in the Eastern Ghats and central peninsular India but also in some places in the Western Ghats. The distribution is highly fragmented and populations are very local, making hilly habitats a very special conservation concern. Many of these hill forests are threatened by granite quarrying, forest fires and grazing. [6] It has vanished from many sites where it was earlier known. [7]

Some well known locations include the Nandi Hills, [8] Horsley Hills, [9] Gingee, [10] Yercaud [11] and the Biligirirangans. [12] The species is also seen in some parts of the Western Ghats including the Anamalais. [13] [14] [15] [16] [17] [18] [19] The northern limit is believed to be in the Nallamala range [20] but it is suspected that the species may extend in range into the northern Eastern Ghats of Orissa. [21] [22]

Behaviour and ecology

This bird is usually shy and hidden within scrub and is usually detected by its sudden cackling outbursts of calls which are similar to those of the white-browed bulbul. They feed on insects and the berries of various scrub plant species including Lantana camara , Flueggea leucopyrus , Toddalia asiatica , Erythroxylon monogynum , Solanum indicum , Santalum album , Ziziphus , Ficus benghalensis , Ficus nervosa , Ficus montana , Canthium dicoccum and Phyllanthus reticulata . [6]

During hot afternoons and in the dry-season they visit pools of water both to drink and bathe. [23]

The breeding season is June to August. The nest is built in the fork of small tree. Two eggs are laid which hatch in 20 days with the chicks fledging 13 days later. [6] [24]

Grey-headed bulbul Species of bird

The grey-headed bulbul is a member of the bulbul family, Pycnonotidae. 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.

Horsley Hills Township in Andhra Pradesh, India

Horsley Hills or Horsleykonda or Yenugulla Mallamma Konda is a series of hills in Andhra Pradesh in Madanapalle Taluk of Chittoor district and is about 9 miles from Madanapalle town. The local name of the hill was Yenugu Mallama Konda after a legend of a saintly old woman named Mallamma who lived atop the hill and was fed by elephants (yenugulu). W.D. Horsley, a British collector, built his home around 1870 after whom it is named. In contrast to the dry and hot surrounding, this area is well vegetated with cooler climate. This made it attractive as a hill station and a tourist spot.

Nandi Hills, India town in Karnataka, India

Nandi Hills is an ancient hill fortress built by Ganga Dynasty and later enlarged and strengthened by Tipu Sultan in southern India, in the Chikkaballapur district of Karnataka state. It is 10 km from Chickballapur town and approximately 60 km from Bengaluru. The hills are near the town Nandi. In traditional belief, the hills are the origin of the Arkavathy river, Ponnaiyar River, Palar River, Papagni River and Penna River. Watching the sunrise at Nandi Hills is popular with tourists. The first ever SAARC summit hosted by India was held at Nandi Hills in 1986.

Painted bush quail Species of bird

Painted spurfowl Species of bird

The painted spurfowl is a bird of the pheasant family found in rocky hill and scrub forests mainly in peninsular India. Males are more brightly coloured and spotted boldly in white. Males have two to four spurs while females can have one or two of the spurs on their tarsus. The species is found mainly in rocky and scrub forest habitats unlike the red spurfowl. It is found in the undergrowth in pairs or small groups, escaping by running and rarely taking to the wing when flushed.

Common hawk-cuckoo Species of bird

The common hawk-cuckoo, popularly known as the brainfever bird, is a medium-sized cuckoo resident in the Indian subcontinent. It bears a close resemblance to the Shikra, even in its style of flying and landing on a perch. The resemblance to hawks gives this group the generic name of hawk-cuckoo and like many other cuckoos these are brood parasites, laying their eggs in nests of babblers. During their breeding season in summer males produce loud, repetitive three note calls that are well-rendered as brain-fever, the second note being longer and higher pitched. These notes rise to a crescendo before ending abruptly and repeat after a few minutes; the calling may go on through the day, well after dusk and before dawn.

Painted francolin Species of bird

The painted francolin or painted partridge is a species of francolin found in grassy areas in central and southern India and in the lowlands of southeastern Sri Lanka. They are easily detected by their loud calls especially during the breeding season. Thomas C. Jerdon noted that the species was found mainly in Central India south of the Narmada and to the east of the Western Ghats as well as the Chota Nagpur and Northern Circars. It can be confused only with the black francolin with which it partly overlaps and is said to sometimes hybridize. This species can be told apart from the female of a black francolin by the lack of a rufous hind collar and the white spots on the underside. The face is rufous and there is no dark stripe running behind the eye.

Flame-throated bulbul 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 by names in the past 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.
