The white-eared bulbul (Pycnonotus leucotis) is a member of the bulbul family. It is found in south-western Asia from India to the Arabian peninsula.

Taxonomy and systematics

The white-eared bulbul was originally described in the genus Ixos. The white-eared bulbul is considered to belong to a superspecies along with the Himalayan bulbul, white-spectacled bulbul, African red-eyed bulbul, Cape bulbul, and the common bulbul.[2] Formerly, some authorities considered the white-eared bulbul to be a subspecies of the Himalayan Bulbul.

Subspecies

Two subspecies are recognized:[3]

  • Arabian white-cheeked bulbul (P. l. mesopotamia) - Ticehurst, 1918: Found in north-eastern Arabia, southern Iraq and south-western Iran
  • P. l. leucotis - (Gould, 1836): Found in southern Iran, southern Afghanistan, Pakistan and north-western India

Description and vocalisations

The white-eared bulbul is rotund in appearance, and has a brownish-grey body. The tail of this bird is relatively long, tapering outwards. Starting off black, the tail feathers end in white tips. The head of the white-eared bulbul is black, with the area around its cheeks bearing a large white spot. The eye rings of the bulbul are bare, and the beak short. The vent of the bird is bright yellow.

The white-eared bulbul does not have a uniform song but rather a set of notes, which can be used to chirp different melodies. The song is brief, but is described as being "pleasant and fluid."[4]

Distribution

It is native to the western reaches of India, much of Pakistan, southern Afghanistan, coastal Iran, as well as much of the two-river basin in Iraq, Kuwait and the island of Bahrain.[5]

It has been introduced to the remaining Persian Gulf countries including Oman, the United Arab Emirates, and Qatar.[6]

Ecology

Usually the females build the nest, which is constructed in the shape of a messy cup from thin twigs, dry grass, and various plant fibers, and is located in a hidden spot on trees. The clutch contains 2–4 eggs, usually 3, very rarely 5. The eggs are creamy white with purple spots.[7] The incubation, which is made by the female, lasts 13–14 days in Pakistan, or 10.5–12.5 days in Iraq. Both parents participate in feeding the chicks, which fledge after 9–11 days (in Iraq). Of 19 nests in Iraq, only three (about 16%) have raised a new generation; this is likely due to predation by crows , as many nests are only poorly concealed.[8] This is a monogamous species , and males tend to aggressively defend nesting territories from other males[9]

Conservation

The species is listed by the IUCN as "Least Concern" as of 2018 but population sizes are declining.[1]
