DERBY FLYCATCHER. 
449. Pitangus sulphuratus derbianus. 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 abeut 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.
