 England and Michigan; winters 

 south of our borders. 



This yellow and greenish species 

 can be identified by its black head, 

 neck and throat, with the large 

 yellow patch about the eye and the forehead. The 

 members of this genus are active fly-catchers, 

 darting into the air after passing insects in the 

 manner of the Flycatchers. They frequent tan- 

 gled thickets where they build their nests within 

 a few inches of the ground, making them of leaves, 

 bark and grass, lined with hair; the four or five 

 eggs are white, specked with reddish brown and 

 neutral tints; size .70 x .50. Data. Doddridge Co., 

 Mo., May 29, 1897. Nest one foot from the ground 

 in a small bush; made of leaves, strips of bark 

 and fine grasses.
