CERULEAN WARBLER. 365 



who have seen them elsewhere. So far as I have observed, this is, 

 not one of the high fliers, being seldom seen among the tree tops, but 

 mostly in young woods, particularly evergreens, where its colors show 

 to advantage against the back-ground of dark foliage. 



When seen in spring, flitting from bush to bush, one is apt tO' 

 suppose that it will not travel much farther before settling for the 

 summer, but Macoun reports finding it at Lake Mistasini on the 

 26th May, 1885, and Richardson met with it on the banks of the 

 Saskatchewan on the 26th May, 1827.

The Cerulean Warbler is, I think, a regular summer resident in 

 Southern Ontario, but is somewhat local in its distribution. One 

 spring I searched for it carefully near Hanjilton without seeing a 

 single individual, while across the Bay, four miles off, Mr. Dickson 

 reported it as quite common, and breeding in the woods near the 

 Waterdown station of the Grand Trunk railway. Its home and 

 haunts are among the upper branches of the trees, and, except on a 

 blustering, rainy day, it is seldom seen among the lower branches. 

 Its song is almost identical with that of the Parula Warbler, but in 

 the latter species it rises to a slightly higher key at the close, while 

 the Cerulean's ditty is uniform throughout. The colors of the bird 

 are very pleasiilg when it is seen in a good light, fluttering among 

 the topmfcst twigs of a beech or maple, the azure-blue and silvery- 

 white seeming like a shred wafted from the drapery of the sky. Dr.. 

 Wheaton mentions the species as abundant in Ohio,, but generally it. 

 is considered rare.
