mosses, and sometimes with hair. Tlie parent birds are very watchful and 

 vigilant if their nest is in danger, and often expo.se their lives in their an.\- 

 iety i'or their young. The male bird is attentive to his mate during incuba- 

 tion, and assists in feeding the young. The young are fed chiefly on insects, 

 frogs, mice, and similar food. 



The eggs of the Crow vary from 1.60 to 1.55 inches in lengtli, and from 

 1.20 to 1.10 in breadth. In their markings they exhibit surprising varia- 

 tions. They usually have a ground of a light sea-green, over which are 

 scattered, more or less thickly, blotches, some of them cj[uite large, of a dark- 

 brown, almost black, with purplish reflections. These are chiefly about the 

 larger end. Another tpiite connnon variety is of a deeper ground of green, 

 very uniformly and thickly sprinkled witli fine dottings of a sepia-brown. 

 Others have a ground nearly white, sliglitly tinged with green, more spar- 

 ingly spotted with small blotches of light purplish-brown. A nest found 

 near Springfield contained eggs having the ground-color on one side a 

 l)inkish-gray, the rest being greenish-white, aU spotted with brown. 

 Another set of eggs from Hudson, Mass., were of a light bluish-green, 

 entirely unspotted, resembling large Eobin's eggs ; and Dr. Wood mentions 

 aaother four, the ground of ^^■hich was flesh-color, and the spots red.

FLORIDA CROW. 



Corvus americanus, var. floridanus, B.41P,d, Biid.s N. Am. 568, pi. l.xvii, f. 1. C. america- 

 nus, Allen, B. E. Fla. 297. 



Sp. Char. About the size of C. americanus, but bill and feet larger. Tail less rounded. 

 Third, fourth, and fifth quills nearly equal; third rather longer than fifth. Color less 

 violet above. Length, 19.50; wing, 12.00; tail, 7.70; tarsus, 2.60. 



Had. Southern peninsula of Florida. 



This resident Crow of Florida differs in some marked features from that 

 of the more northern localities in several characters. Although perhaps 

 rather smaller, the bill and feet, especially the latter, are very considerably 

 larger. The nasal featliers extend over the basal two fifths of the bill, 

 instead of the half The proportions of the bill are about the same ; in 

 the Florida liird it is rather the longer. Tlie greatest difference is in the 

 feet. The tarsal joint of the til^ia is bare, the feathers scarcely coming 

 below it, even anteriorly, instead of projecting some distance. The tarsus 

 is almost a quarter of an inch longer, covered ailteriorly by nine scutelke, 

 instead of eight. The outer latei'al toe is shorter, not reaching the base 

 of the middle claw. The middle toe and claw are considerably shorter than 

 the tarsus ; the middle claw is shorter than in the northern bird. 



The wing-formula differs somewhat ; the third, fourth, and fifth ipiills are 

 nearly equal, the third even longer than the fifth, instead of shorter. Tiie
