Distribution. Occurs over the whole of the Nilgiris from 4500 feet to the summit of the hills.
Habits, &c. Jerdon describes this bird as being noisy and abundaut in all the woods on the summit of the Nilgiris, and, like others of the genus, living in small scattered flocks foraging about the thick brushwood.
It breeds from February to June, building a deep nest, which is frequently lined with fur and feathers, in bushes. The eggs are three to five in number, blue marked with red and brown, and measure 1.0 by .76.
