often pointed, ovals. Fifty eggs average 23.6 × 17.3 mm., the extremes being 25.5 × 18.0 mm., 22.1 × 17.6 mm. and 24.0 × 16.3 mm. The greatest length and breadth occurs in the same egg.
Habits. The Brown-eared Bulbuls come well into the plains in winter but in summer keep above 2,000 feet and ascend to 6,000 or perhaps 7,000 feet. They collect in very large flocks containing 20 to 30 individuals and haunt both the higher trees and low scrub and brushwood. They are noisy birds and have many harsh notes but they also have a rather pretty, jerky little song which they sing at all seasons. They keep much to the more open wooded parts until the breeding season commences, when they retire to the deeper forests. They have a curious habit of swinging themselves on the pliant ends of the small bamboo, Bambusa vulgaris, several birds often perching on the same hanging end and evidently enjoying themselves as they sway in the breeze.
