BIRDS OF SOUTHERN VERACRUZ — WETMORE 323 



ICTERUS GALBULA (Linnaeus) : Baltimore Oriole 



Coracias Qalbula Linnaeus, Systema naturae, ed. 10, vol. 1, 1758, p. 108 

 (Virginia). 



This oriole was not common in 1939. I saw one on March 18, 

 and shot an adult male April 10 at Tres Zapotes. Carriker secured 

 females here in 1940 on January 18 and 25, and an adult male on 



Cerro de Tuxtla, April 9.

ICTERUS SPURIUS (Linnaeus) : Orchard Oriole 



Oriolus spurius Linnaeus, Systema naturae, ed. 12, vol. 1, 1766, p. 162 (South 

 Carolina). 



Near Tres Zapotes this oriole was common and was present 

 through the winter, as Carriker secured a male on January 20 and 

 a female on January 26. "We took a number of specimens in March 

 and April. In 1939 I noted definite migratory movement among 

 them from March 20 to 22, when they were present in abundance 

 through the thickets and the overgrown abandoned milpas. On 

 March 31 another migration wave passed with the birds everywhere 

 from low brush to the tree tops. On April 6 and 10 they were seen 

 in large numbers sometimes in flocks, and on April 13 they were 

 noted in small loosely formed flocks at the Arroyo Teponaguasapan. 

 I saw them on April 15 on my last day in the field. On the days 

 when they were in migration they were so widespread that it was 

 necessary to scrutinize carefully every bird that I collected to avoid 

 taking orchard orioles that I did not want. They called but I heard 

 none singing. 



ICTERUS FUERTESI Chapman 



Icterus fuertesi Chapman, Auk, 1911, p. 3, pi. 1 (Paso del Haba, south shore of 

 Rio Tamesi, 35 miles northwest of Tampico, Tamaulipas). 



Among the orioles secured by Carriker there is a fine adult male of 

 this bird taken at Tlacotalpam, May 17, 1940. This is in full 

 plumage and agrees closely in the light, buffy brown color of the 

 under surface and rump with the plate accompanying the original 

 description. It is, however, definitely larger than the specimens ob- 

 tained by Dr. Chapman in Tamaulipas, being similar in size to the 

 smaller individuals of Icterus spurius. The measurements are as 

 follows : Wing 76, tail 65.6, culmen from base 17.5, tarsus 21.2 mm. 



A female collected by Carriker on May 15, 1940, near the coast at 

 El Conejo I have also identified as fuertesi. It is in slightly worn 

 plumage and when compared with Icterus spurius in similar stage 

 differs in faintly paler hue of the under surface and the rump. Like 

 the male from Tlacotalpam it is larger than the female described by 

 Dr. Chapman from Tamaulipas, as it measures as follows: Wing 72.5,
