VENEZUELAN ORNITHOLOGY — FRIEDMANN AND SMITH 505 



This woodpecker is so similar in general appearance to Dryocopus 

 lineatus, previously recorded by us from Cantaura that the relative 

 abundance of each in the study area is uncertain, since too large a 

 percentage of the sight records are thereby put in doubt. The 

 somewhat lighter colored bill of Phloeoceastes appears to be its best 

 field mark.

Xenops rutilus heterurus Cabanis and Heine 



Xenops heterurus Cabanis and Heine, Museum Heineanum, vol. 2, 1859, p. 33 

 ("Columbia"? Bogotd, Salvin, Ibis, 1809, p. 319). 



1 Juvenal unsexed, Caicara, May 25, 1952; gonads very small; skull soft; 

 maxilla brown, mandible horn color; feet dark gray; gizzard contained (wood- 

 boring?) beetle larvae. 



While the specimen reported in our previous publication was taken 

 in the densest part of the lowland seasonal forest, the present example 

 was found in very sparse deciduous seasonal woods, near the open 

 savanna.

The following observations by the collector add to our knowledge 

 of the habits of this bird: On July 31, a male Vv^as observed about 10 

 feet up in a bush "displaying" to a Volatinia jacarina somewhat 

 below. The display was very striking, even from a distance. Crest 

 erect, body feathers fluffed out, body horizontal, the bird would 

 "quiver" forward, somewhat as if in the act of copulation, tail being 

 raised and lowered as body shifted forward. No sound was heard, 

 (the collector was not very near) but the bill was opened. A white 

 supercilliary line was very apparent when the crest was so raised. 



Family Cotingidae: Chatterers

Psaris marginatus tristis Kaup, Proc. Zool. Soc. London, vol. 19, 1851 (October 

 1852), p. 48 (no locality stated; Cayene suggested by Bangs and Penard, 

 Bull. Mus. Comp. Zool., vol. 64, 1921, p. 387). 

 1 cT, Caicara, May 15, 1952; one testis enlarged, one atrophied; iris brown; bill 

 blue-gray; feet black. 



1 9 , Cantaura, October 20, 1952. 



This form was found in the dense lowland seasonal forest at Caicara 

 and in the sparse deciduous seasonal woods at Cantaura. The two 

 examples collected were the only ones seen.
