DERBY FLYCATCHER. 



449. Pitangus sulphuratus derhianus. 10^ 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 TexaSc
