The birds of the Windward Islands, probably including those of the 

 north coast of Colombia and Venezuela, have been separated sub- 

 specifically as JJ . a. cancrlvorus, while those inhabiting the region 

 from eastern Panama to southern Ecuador are recognized by some 

 authors under the name suhtilis^ sometimes as a full species and some- 

 times as a subspecies of anthracina. 



The species has been detected in February in southern Arizona, 

 indicating that at least some individuals are not migratory. On the 

 other hand, it has been observed to arrive at Tucson, Ariz., on March 

 13; at Agua Fria, on March 26; and at Apache Tejo, N. Mex., on 

 April 12.

 mind, one of the prettiest hawks I had ever seen. 



The mesquite forest, where these hawks were quite common, was 

 on the banks of the Santa Cruz River and is more fully described 

 under the preceding species. Major Bendire (1892) also found them
