This delicate little species is now, for the first time, introduced 

 to public notice. Except my friend Mr Peale, I know of no 

 other naturalist who seems to have hitherto known of its 

 existence. At what time it arrives from the south I cannot 

 positively say, as I never met with it in spring, but have 

 several times found it during summer. On the borders of 

 streams and marshes, among the branches of the poplar, it 

 is sometimes to be found. It has many of the habits of the 

 flycatcher ; though, like the preceding, from the formation of 

 its bill, we must arrange it with the warblers. It is one of 

 our scarce birds in Pennsylvania, and its nest has hitherto 

 eluded my search. I have never observed it after the 

 20th of August, and therefore suppose it retires early to the 

 south. 



This bird is four inches and a half long, and seven and a 

 half broad ; the front and upper part of the head is of a fine 

 verditer blue ; the hind head and back of the same colour, 

 but not quite so brilliant ; a few lateral streaks of black mark 

 the upper part of the back ; wings and tail, black edged with 

 sky-blue ; the three secondaries next the body edged with 

 white, and the first and second row of coverts also tipt with 

 white ; tail-coverts, large, black, and broadly tipt with blue ;
