Dendroioa caerulesoens 
Lake Umbagog. 
Call Hotes. 
1898. 
Dendroioa caerulescens has two notes which closely re- 
Sept.l. semble those of the Junco. One is a soft tsun , the other a 
tittering flight call (ti-ti-ti-ti-ti ) exceedingly like that 
made by the Junco when first taking flight but less loud. 
These Warblers are exceptionally numerous here this autumn. 
I saw at least a dozen this morning. They are often seen in 
the tops of tall trees at this season.
