NOKTH A^[ERICAN BIRDS. 



tail is slioit Jind very iioarly even, tlie ditlereiice in leni^th of feathers being 

 less than lialf an incli, instead of an inch. This, liowever, may in i>art l)e 

 owinuj to the ahscnee of tiie niicMle i)air. 



The colors diilcr somewhat from those of tlie connnon Crow. There is 

 less violet, and the feathers of the back have abnost a brassy gloss on liieir 

 mar^iins, as in Crnti>j)Jnni((. 



Tlie specimen npon which thes»» remarks are based, though apj)arently 

 perfectly niaiure, is changing some of its feathers, such as tlie inner prima- 

 ries, the middle tail-feathers, and the greater coverts. The long primaries 

 and ten tail-feathers, however, are of full length. It is possible that the 

 bird is really as large as the noi-thern Crow, idtiiough this is hardly probable. 

 It was killed on the mainland of the extreme southern portion of Florida, 

 not far from Fort Dallas. 



Xo com])arison of this bird is required witli the Fish Crow, which has the 

 nnddle toe and cla\v lt)nger than the tu.sus, not shorter, and the proportions 

 much less. 



Haijits. The connnon resident Crow of Florida exhibits so many pecu- 

 liarities differing from th(^ northern species, that I*rofessor Baird, in his 

 Uirds of America, deemed it worthy of mention at least as a race, if not a 

 distinct species. We have no account of its habits, and do not know if, 

 in any res])ects, thev differ from those of the common Crow. Dr. J. C. 

 Cooper, in his brief manuscrij)t notes on the birds of Florida, made in the 

 spring of ISo!), sj>eaks of the Flori«la Crow as very connnon, as lieing (juite 

 maritime in its habits, and as having fuU-tledued young on the 20tli of 

 April. Three eggs of this race, obtained in Florida in the spring of 1871, 

 by Mr. ]\Iavnard, dilfer not more from those of the Crow than do those of the 

 latter occasionally from one another. They measure l.To by 1.20 inches ; 

 1.70 by 1.20 ; and 1.54 by 1.25. Their ground-color is a bright bluish-ureen, 

 and thev are all more or less marked, over the entire egg, with blotches of a 

 mingled l)ronze and brown with violet shadinLis. The latter tints are more 

 marked in one egg than in the others, and in tbis the spots are fewer and 

 more at one end, the larger end being nearly free from markings. Their 

 average capacity, as compared with the average of the C. anicriciuiu^, is as 

 5.1 to 4.2.
