VIREO FALLENS SEMIFLAVUS Salvin 



Vireo semiflavus Salvin, Proc. Zool. Soc. London, 1863, p. 188 (Sakluk, Pet6n, 

 Guatemala"). 



On December 4 in swampy tliickets back of the beach on a small 

 island opposite Puerto Barrios these birds were found in pairs, and 

 three were taken. Attention was drawn to them by a wrenlike, chat- 

 tering- call. In the three taken the sexual organs were not developed. 

 The iris was brownish white. 



In identifying these as semiflavus I have followed current under- 

 standing of the races of this bird, which from material at hand 

 are not altogether clear to me. The three from Puerto Barrios have 

 extraordinarily large bills, much larger than one from Belize, or a 

 series from Campeche and Yucatan, equaling in this the only speci- 

 men I have seen of the duller-colored F. p. paluster Moore.

A male was taken above Dueilas on November 1, at an elevation of 

 6,500 feet on the north face of Volcan de Acatenango.

Muscicapa gllva Vieillot, Histoire naturelle des oiseaux de I'Am^rique septeu- 

 trionale, vol. 1, 1807 (1808), p. 65, pi. 34 (New York). 



Near Panajachel these migrant vireos were common in dense groves 

 in the valley above the village on November 11 and 15, two being 

 taken on each of these days. On November 29 I found a number in 

 a coffee finca at 3^200 feet elevation near Las Lajas below Alotenango 

 and shot two more. Here they were feeding on wild fruits and came 

 constantly to the fruit-bearing trees, calling querulously. All taken 

 are of the eastern race.
