378 BIRDS OF ONTARIO. 



about eyes. Yining birds have little or no ashy on the head and no black on 

 the throat, thus nearly resembling the Oporoniin atjUu. Length, 5:^-5^; wing 

 and tail, each about 2J. 



Hab. — Eastern North America to the Plains, breeding from the mountain- 

 ous portions of Pennsylvania, New England and New York, and Northern 

 Michigan northward. Central America and northern South America in winter. 



Nest, on or near the groimd, built of leaves and weed stalks, and lined with 

 tine Ijlack rootlets. 



Eggs, three; "light flesh color, uniformly speckled with fine brown specks." 



Very little is yet known of the nest and eggs of the Mourning 

 Warbler. The above description is given by John Burroughs of a 

 nest found by him in New York State, which is farther south than 

 these birds usually spend the summer. 



Some years ago, while waiting for the train at a way station on 

 the Kincardine branch of the Grand Trunk Railway, I strolled into 

 the neighboring woods to pass the time. Sitting on a prostrate log 

 on the sunny side of a ravine, birds of many kinds fluttered about, 

 and a pair of Mourning Warblers soon attracted my attention by 

 the displeasure and anxiety they manifested at being disturbed. I 

 changed my position, and the female moved cautiously towards the 

 place I had left. A few minutes more and I certainly should have 

 seen the nest, but the engine whistle sounded, and being some 

 distance from the station I had to leave. Next day, as the train 

 slowly passed the place, the male was again observed singing on his 

 former perch. 



Any one who has given attention to the movements of the birds 

 for a number of years, must have been surprised at the persistent 

 regularity with which certain species appear at particular places at 

 a given time, especially in spring. 



For many years after I commenced collecting birds, I considered 

 the Mourning Warbler only a straggler in this part of Ontario, 

 having met with it on but two occasions. More recently, I have 

 carefully studied the topographical aspect of the neighborhood with 

 special reference to the habits of the birds, and have calculated 

 where certain species should be found at certain dates. One result 

 of this was, that on two visits made to a particular place in May, 

 1 885, K. C. Mcllwraith obtained nine Mourning Warblers in a very 

 short time. In the spring of 1886 they were again observed at the 

 same place, but were not molested. The name Mourning does not 

 refer to the manners of the bird, for it sings with much spirit and 

 is quite lively in its movements, but was suggested by the ashy tips
