COTINGAS. Family COTINGIDAE 
[441.1.] Xantus Becard. Platypsaris aglaice albiventris. 
Range. — Mexico; north casually to the southern border of Arizona. 
This peculiar species is grayish above and lighter gray below, has dark slaty 
crown, and a patch of rose color on the lower throat. This 
is the only representative of this tropical family that has 
been found as yet over the Mexican border, but its near 
ally, the Rose-throated Becard has been found within a 
very few miles and will doubtless be added to our fauna 
as an accidental visitor ere long. Their nests are large 
masses of grasses, weeds, strips of bark, etc., partially 
suspended from the forks of branches. Their eggs number 
four or five and are a pale buffy gray color, dotted and scratched with a pale 
reddish brown and dark gray. Size .95 x .70. The one figured is from a set 
in the collection of Mr. Crandall, taken June 1, 1897 at Presidio Sinaloa, Mexico.

adorned with a slight crest or a coronal mark of orange, red, or yellow. Only- 
two of the species found in North America are gaudy in plumage, the Vermil- 
ion, and the Derby Flycatchers. They all have the habit of sitting erect on a 
dead twig, and watching for passing insects, which they catch on the wing.
