 on the steep side of a ravine full of small birch trees ; but it was 

 empty, and the eggs are still undescribed. According to Dr. Scully, 

 Blyth, and other observers, this Warbler frequents small bushes and 

 is of restless habits ; its note is said by them to be weak and 

 resembles tiss-yip, tiss-yipp, often repeated ; while Sabanaeff says 

 that — in the breeding-season — its note is a very shrill psi, psi. The 

 bird is the Greenish Tree-Warbler of Jerdon.

 of the wing being nearly white ; the tips of the greater wing-coverts 

 are yellowish-white, and form a conspicuous single bar; bill brown 

 above, yellowish-brown below; tarsi dark olive. Length, 4'25 in. ;
