Swains., Bonap. and many others.—Nauclerus forficatus, Wils., Aud. 
A remarkable hawk, instantly recognizable at almost any distance by 
its resemblance to a gigantic Barn Swallow, the slender wings and deeply 
forked tail rendering it unmistakable. 
Distribution.—United States, especially in the interior, from the Carolinas 
and Minnesota southward throughout Central and South America; west- 
ward to the Great Plains. Casual eastward to southern New England 
and northward to Manitoba and Assiniboia. 
This remarkable bird must be regarded as merely a wanderer from the 
south which has been taken in Michigan perhaps half a dozen times in the 
last thirty years.
