often pointed, ovals. Fifty eggs average 23°617-3 mm., the 
extremes being 25°5x18°0 mm., 22:117:6 mm. and 24:°0x 
163mm. The greatest length and breadth occurs in the same 
ege. 
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 havea 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.
