DERBY FLYCATCHER. 



449. Pitangus sulphuratus derbianus. lOMi inches. 



This imposing flycatcher is the largest of the family 

 that is found in North America. As usual with mem- 

 bers of the family it is of a quarrelsome disposition, 

 but hardly so much so as either the common or Arkansas 

 Kingbirds. Their large, heavy bodies render them con- 

 siderably less active than the smaller members of the 

 family. On account of the size of the head and bill, they 

 are often known as Bull-headed Flycatchers. 



Notes. Very varied, but similar in character to 

 those of the eastern Kingbird. 



Nest. It is said to build its nest at low elevations 

 in trees or in thorny bushes a large structure of twigs 

 and rubbish with an entrance on the side. The three 

 to five eggs have a cream-colored ground and are prom- 

 inently specked about the large end with brown ( 1 15 x 

 .82). 



Range. A Mexican species that is fairly common in 

 the Lower Rio Grande Valley in Texas.
