The Yellow-eared Bulbul (Pycnonotus penicillatus, Blyth, 1851) is one of Sri Lanka's most distinctive endemic birds. Confined to the island's central highlands and a handful of other montane forest patches, it rewards patient birdwatchers with a combination of striking plumage, a sharp, carrying call, and relatively gregarious feeding behaviour — rare for a shy forest bird.
How do you identify the Yellow-eared Bulbul?
Identification is straightforward once you know what to look for. A bright tuft of yellow feathers over each ear coverts and a crisp white supercilium in front of the eye set this species apart from every other bulbul found in Sri Lanka. Adults measure roughly 18.5–20 cm in length. Females closely resemble males but are marginally smaller and show broad yellow tips to the tail feathers — a reliable field mark when the bird fans its tail during perching or display.
The call is equally diagnostic: a sharp, repeated whee-whee-whee that carries well through montane forest. Once learned, it will alert you to birds before they come into view.
Where does the Yellow-eared Bulbul live in Sri Lanka?
This species is a high-altitude specialist. The core population is found above 1,700 metres in the central highlands, though birds occasionally descend to around 1,100 metres on the wetter western slopes of the mountains. On the drier eastern slopes they are rarely recorded below 1,200 metres. Outside the main massif, smaller populations occur in the Horton Plains National Park area, the Knuckles Range, and the higher fringes of the Sinharaja Forest Reserve.
Within these elevations, the birds favour intact montane forest and forest edges, occasionally venturing into large gardens that border natural woodland. They are rarely seen in degraded or heavily disturbed habitat.
What is the best time to see the Yellow-eared Bulbul?
The Yellow-eared Bulbul is a resident species, present year-round. Birdwatching is productive during both main breeding peaks — March to May and August to October — when adults are particularly active and vocal as they establish territories and provision nestlings. Outside breeding seasons, mixed-species foraging flocks in the mid-canopy are the most reliable way to locate the species. Early mornings, before the highland mist thickens, typically offer the clearest sightings.
What do Yellow-eared Bulbuls eat?
The diet is dominated by berries and small fruits, and flocks often congregate wherever fruiting shrubs or mid-canopy trees are in season. They forage actively at shrub level and in the lower to middle canopy, sometimes gathering in groups of a dozen or more birds at a productive food source. Occasional insect foraging has been noted, particularly during the breeding season when protein demand is higher.
How does the Yellow-eared Bulbul breed?
Breeding occurs throughout the year but shows two distinct peaks: March–May (the primary season) and August–October. The nest is an open, cup-shaped structure built in a tree fork typically 3–5 metres above ground. Construction relies heavily on green moss for the outer walls, while the inner cup is lined with fine ferns and rootlets — materials that are abundant in the moist montane forests the species inhabits.
Eggs are speckled, sometimes appearing pinkish with reddish-brown markings, and measure approximately 23.4 × 16.7 mm. Both parents share incubation duties and feed the chicks after hatching, a cooperative behaviour common in bulbuls. Clutch size is typically two to three eggs.
Which are the best birding sites for Yellow-eared Bulbul in Sri Lanka?
Several highland localities consistently produce good sightings:
- Horton Plains National Park — the plateau edge and forest remnants hold a healthy resident population, accessible on the standard walking circuit.
- Knuckles Range — particularly the upper forest trails above Rattota and Meemure, where cloud forest provides ideal habitat.
- Nuwara Eliya surrounds — forest patches around the town and adjacent estates can yield sightings, especially in the early morning.
- Sinharaja upper border — the higher elevations on the reserve's northern and eastern edges occasionally support the species.
- Hakgala Strict Nature Reserve — the montane scrub and adjoining forest above Nuwara Eliya are reliable sites.
For first-time visitors, a local birding guide familiar with current fruiting trees is worth arranging; the birds' exact locations within a site shift week to week depending on food availability.
Is the Yellow-eared Bulbul an endemic species?
Yes. Pycnonotus penicillatus is entirely endemic to Sri Lanka — it occurs nowhere else in the world. The species is classified as Near Threatened on the IUCN Red List, reflecting its restricted range, dependence on intact montane forest, and sensitivity to habitat degradation and climate-driven upslope shifts in suitable conditions. Conservation of Sri Lanka's remaining highland forests is therefore directly linked to the long-term survival of this species.
How should I plan a birding trip to see highland endemics?
A focused highland birding itinerary typically combines cloud forest walks with early-morning sessions at established sites such as Horton Plains. Two to three days based in the Nuwara Eliya or Kandy areas allows enough time to cover the main elevation bands where endemic species are concentrated. Lakpura can arrange private driver-guide services that include naturalists experienced in locating montane endemics, reducing the time spent searching and maximising actual observation time.
