Vietnamese birds, Red-whiskered bulbul, Pycnonotus jocosus, Songbird

The #RedWhiskered #bulbul ( #Pycnonotus #jocosus ), or crested bulbul, is a passerine #bird found in Asia. It is a member of the bulbul family. It is a resident frugivore found mainly in tropical Asia. It has been introduced in many tropical areas of the world where populations have established themselves. It feeds on fruits and small insects. Red-whiskered bulbuls perch conspicuously on trees and have a loud three or four note call. They are very common in hill forests and urban gardens within its range. The red-whiskered bulbul was originally described with the shrikes within the genus Lanius in 1758 by Carl Linnaeus in his Systema Naturae. Hybrids have been noted in captivity with the red-vented, white-eared, white-spectacled, black-capped and Himalayan bulbuls. Leucism has also been recorded. The red-whiskered bulbul is about 20 centimetres (7.9 in) in length. It has brown upper-parts and whitish underparts with buff flanks and a dark spur running onto the breast at shoulder level. It has a tall pointed black crest, red face patch and thin black moustachial line. The tail is long and brown with white terminal feather tips, but the vent area is red. The loud and evocative call is a sharp kink-a-joo (also transcribed as pettigrew or kick-pettigrew or pleased to meet you) and the song is a scolding chatter. It is more often heard than seen, but will often perch conspicuously especially in the mornings when they call from the tops of trees. The life span is about 11 years. This is a bird of lightly wooded areas, more open country with bushes and shrubs, and farmland. Irruptions have been noted from early times with Thomas C. Jerdon noting that they "periodically visiting Madras and other wooded towns in large flocks." On the island of Réunion, this species established itself and also aided the spread of alien plant species such as Rubus alceifolius. In Florida they feed on fruits and berries of as many as 24 exotic plants including loquat (Eriobotrya japonica), Lantana spp., Brazilian pepper (Schinus terebinthifolius) and figs (Ficus). In Mauritius they aid the dispersal of Ligustrum robustum and Clidemia hirta. Seeds that pass through their gut germinate better. Populations of the red-whiskered bulbul on the island of Reunion have diversified in the course of thirty years and show visible variations in bill morphology according to the food resources that they have adapted to utilize. The breeding season is spread out and peaks from December to May in southern India and March to October in northern India.Breeding may occur once or twice a year. The courtship display of the male involves head bowing, spreading the tail and drooping wings.The nest is cup-shaped, and is built on bushes, thatched walls or small trees. It is woven of fine twigs, roots, and grasses, and embellished with large objects such as bark strips, paper, or plastic bags. Clutches typically contain two to three eggs. Adults (possibly the female) may feign injury to distract potential predators away from the nest. The eggs have a pale mauve ground colour with speckles becoming blotches towards the broad end. Eggs measure 21 mm and are 16 mm wide. Eggs take 12 days to hatch. Both parents take part in raising the young. Young birds are fed on caterpillars and insects which are replaced by fruits and berries as they mature. The chicks are psilopaedic (having down only in the pterylae). #Eggs and #chicks may be preyed on by the greater coucal and crows. They defend territories of about 3,000 square metres (32,000 sq ft) during the breeding season.They roost communally in loose groups of a hundred or more birds. The red-whiskered bulbul #feeds on fruits (including those of the yellow oleander that are toxic to mammals), nectar and insects. Thank you very much for views, comments and likes!
