Quiscalus quiscula aeneus Ridgway. Bronzed Grackle. 
Abundant in the swamps, and quite common in the woods, 
in which zone the species nests. 
Loxia curvirostra minor (Brehm). Crossbill. 
A rare late fall or very early spring visitor to zone seven. 
Two flocks were seen, both migratory, and the birds were not 
feeding. Apparently are not present every season. 
Acanthis linaria linaria (Linnaeus). Redpoll. 
An uncommon winter visitant, of which few are to be found in 
the outer area of zone seven, and in the region of zone eight 
proximal to it. 
Astragalinus tristis tristis (Linnaeus). Goldfinch. 
Abundant in zone six during the spring migration, and common 
there and in zone five at other times of the year. A breeding 
species during late July. 
Passer domesticus (Linnaeus). English Sparrow. 
Mentioned simply because the species is conspicuous by its 
absence. Has not been seen within the formation, though 
it is abundant all around it! 
Plectrophenax nivalis nivalis (Linnaeus). Snow Bunting. 
Quite a common visitor to the open fields during the winter 
months. Frequently seen in large flocks feeding upon the weed 
seeds of the area. 
Pooecaetes gramineus gramineus (Gmelin). Vesper Sparrow. 
A common species in zone eight, where it breeds. One indi- 
vidual shot in May had eaten three small crickets and several 
beetles. 
Ammodramus savannarum australis Maynard. Grasshopper 
Sparrow. 
A few birds of this species probably breed in zone eight, where 
they are more often heard than seen. 
Passerherbulus henslowi henslowi (Audubon). Henslow 
Sparrow. 
A rather rare migrant in zones six and eight (border area). 
Strictly a ground species, feeding largely upon ground insects 
and seeds. 
Zonotrichia -querula (Nuttall). Harris’s Sparrow. 
A very rare species, of which one specimen was secured in 
zone eight (7).
