SPECIMENS COLLECTED 



1 cf, Cantaura, June 8, 1948; gonads small, iris brown; gizzard contained a 

 mouse. 



2 9 , Caicara, February 10 and March 25, 1948; gonads enlarged (much enlarged 

 in the February bird, which showed small yolks) ; iris dark brown, bill black; 

 gizzard of one contained a rat, that of the other the remains of an unidentifiable 

 small mammal. 



These thi^ee specimens of a fairly rare owl are all in good plumage. 

 The male is much whiter, less buffy ochraceous below than the 

 females. In this respect it agrees with another adult male from 

 Petrolea, Santander del Norte, Colombia, The male and one of 

 the females have the black dorsal streaks much broader than does 

 the second female; the latter agrees in this respect with an unsexed 

 bird from Costa Rica. None of them show any approach to oberi 

 Kelso, from Tobago (type examined). In his original description 

 of oberi (Auk, 1936, p. 82) Kelso writes of having seen five specimens 

 of clamator from the Venezuelan mainland; these together with the 

 present three examples, indicate that this owl is not uncommon in 

 northern Venezuela. 



This owl was common in the deciduous seasonal forest, both at 

 Cantaura and Caicara. It was recorded in March, April, May, and 

 July. One was also collected in the lowland seasonal forest. In 

 March, in two consecutive years, a flock of at least 15 individuals was 

 encountered at the same spot in the deciduous seasonal forest at 

 Caicara. 



Local name, "lechuza."

specimen collected 



1 cf , Cantaura, July 13, 1947; gonads very small; iris yellow; gizzard empty. 



This specunen is the type and only known example of its race. As 

 stated in the original description it is a dark form with a pale tail, 

 resembling A. f. bogotensis Chapman of the Colombian-Ecuadorian 

 highlands in its general dark color above but differing from that race 

 in having the ochraceous-buffy markings somewhat more extensive, 

 in having a strikingly paler tail, the central rectrices being light 

 ochraccous-buff barred broadly with fuscous, the pale and the dark 

 bands about equal in width (the dark ones very much wider than the 

 pale ones in bogotensis) and the lateral rectrices similar with the
