﻿VENEZUELAN ORNITHOLOGY — FRIEDMANN AND SMITH 445

 call note. 



Local name, "gavilan," hawk. 



ACCIPITER BICOLOR BICOLOR (Vieillot) 



Sparvius bicolor Vieillot, Nouv. Diet. Hist. Nat., vol. 10, 1817, p. 325 (Cayenne), 



SPECIMEN COLLECTED 



1 9 , Cantaura, February 16, 1946; gonads not enlarged; eye ring and iris yel- 

 low, cere black with a greenish tinge, tarsi and toes yellow-grccn. 



This example is in rather worn plumage and may be a youngish 

 bird as it has the thighs suffused with pale ochraceous-buff and 

 banded with a darker shade of the same color. 



The collector saw this hawk only once, the one collected, in the 

 diy woods near Cantaura. 



The local name is "gaviian coronado," which refers to the band 

 of white that runs around the nape. 



HETEBOSPIZIAS MERIDIONALIS MERIDIONALIS (Latham) 



Falco meridionalis Latham, Index ornithologicus, vol. 1, 1790, p. 36 (Cayenne). 



SPECIMEN COLLECTED 



1 cf, Cantaura, September 14, 1947; gonads small; iris dull orange-yellow, 

 cere ivory yellow, feet pale yellow, bill black, dull yellow at base of mandible; 

 gizzard contained one large grasshopper and one small lizard. 



The bird is inmiature, having the throat and breast streaked, not 

 barred, but it shows signs of molt, as a patch of adult-type barred 

 feathers are present on each side of the upper breast, and some of 

 the rectrices are only partly grown. 



This hawk was found on the savamia, particularly where the trees 

 became numerous, and at times in the deciduous seasonal forest edge. 

 It was recorded in every month of the year, although it apparently 

 increased in numbers in June and July. Perhaps this marked the 

 end of the breeding season, as many apparently immature bird* were 

 seen at this time. 



The call of this hawk was a loud whistled scream. 



Local name, ''gavilan," hawk.
