132 HERONS AND BITTERNS. 



gray, darker than in A. heroJias, with a siiniUxr throat line of white, black, 

 and rufous. Under wing-coverts streaked with white ; rufous of edge of wing 

 less extensive than in A. lierodias^ that of tibiae paler. Tibiae and soles of feet 

 yellow ; tarsi and top of toes yellowish green. Im. — Like young A. herodias; 

 top of head dusky, the feathers with whitish shaft lines and bases. Lesser 

 wing-coverts speckled with rusty, the under ones pure white" (Coues). "L., 

 48-00-50-00; W., 20-00-21 -00; B., 5-95-6-50 ; Tar., 7-95-8-25" (Eidgw.). 



193. Ardea wardi Rldgw. Ward's Heron. — This is the Florida rep- 

 resentative of u-i. herodias. It is believed by some ornithologists to be a dis- 

 tinct species, but in my opinion is a peninsular race. The average differences 

 in color between it and A. herodias consist in its whiter lower parts, darker 

 neck, and olive instead of black legs. These differences, however, can not 

 always be relied upon, and size is the character by which the two birds can 

 best be distinguished, wardi being the larger, as the following measurements 

 show: L., 52-00; W., m5-20-50; B., 6-40-6-80 ; Tar., 8-00-8-50.
