often pointed, ovals. Fifty eggs average 23'6x 17'3 mm., the 

 extremes being 25'5xl8'6 mm., 22'1 X 17'6 mm. and 24'Ox 

 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, 

 Bcimbusa vulgaris, several birds often perching on the same 

 hanging end and evidently enjoying themselves as they sway in 

 the breeze.
