BIRDS OF CUBA IO7 



slightest sign of danger to retire to the lonely pine-clad fastnesses where 

 they roost. 



The voice of this Crow recalls that of the Fish Crow; the other species, 

 Corvus nasiciis, cackles and croaks but does not caw. The nest and eggs 

 are unknown. The bird may be expected sooner or later to disappear, 

 but since the territory where it now is found has no agricultural future, 

 the Cao Pinalero may persist longer than the Cao Montero. 



202. Vireo gundlachii Lembeye. 



JUAN-CHIVl'. 



Few Spanish names are more apt than that of Juan-chivi, for the 

 constantly repeated song of Gundlach's Vireo has almost exactly the 

 sound of these words. Abundant, tame and very inquisitive, this is one of 

 the birds met with in every tract of woods and in the manigua (second- 

 growth bush) as well. They creep tirelessly through the tangles of vines 

 and creepers, bejucales, as such thickets are called, searching for insects, 

 and here also these little green Vireos make their pocket nests in March 

 and April. 



Todd's race orientalis from eastern Cuba is not worthy of recognition; 

 with a large series before me, and having had the opportunity to study 

 his typical materia! as well, I find as much and even more difference in 

 pairs of birds from the same locality in western Cuba as between his type 

 and any one of our enormous series. These West Indian Vireos tend strongly 

 toward dichromatism, and while the present species shows this less than 

 does ochraceus or crassirostris, nevertheless it is perfectly evident. Todd's 

 type was taken in October, and most of the material in American museums 

 available for comparison has been collected between January and May or 

 June. Therefore it is not improbable that this may have misled him. 

 The fact remains that his type and another from Guantanamo can be 

 matched in every respect by specimens from Cojimar (M. C. Z., no. 

 67,634), and from La Jaimanita (M. C. Z., no. 67,632), both places near 

 Havana; while a pair taken by Zappey at Cayo Bonito (M. C. Z., nos. 

 113,399 and 113,400) differ as much from each other in color of both the 

 upper and under parts as do any two examples either in Todd's or in my 

 own series.
