J3YNONYMY OF DENDRCECA CGERULEA 267 



are beard at frequent intervals to rehearse their curious love- 

 songs as they wage their war of extermination against insects 

 on every leaf and limb. 



From such data as these, representing nearly all that is posi- 

 tively known respecting this bird, it is not difficult to make out 

 its movements and mode of life to see how, entering our ter- 

 ritory from the south in April, it disperses to breed over all the 

 coniferous regions of the West, at the higher altitudes only in 

 the south, but down to the general level of the country in re- 

 gions farther north ; how it returns to its winter home, trooping 

 through the whole country irrespective, in a great measure, of 

 the kind of forest vegetation it may encounter; how diligently 

 it forages for its insect prey, and with what repetition the emo- 

 tions of the nuptial hours are expressed. Such are traits that 

 nearly all Warblers share ; but the observant ornithologist finds 

 ample room to enlarge his experiences and increase his sources 

 of thoughtful pleasure in noting those nice points which, like 

 the touches of color upon the plumage, stamp an individuality 

 upon each member of this attractive group of birds.
