AKDEA WURDEMANNII, Baird. 
Florida Heron. 
Sp. Ch. — Lower half of tibia bare. Above bluish ash. Edge of wing and the tibiae rufous. Middle of throat white, streaked 
with black and rufous. Neck ash-colored. Head white, with a patch in the forehead black. Under parts white ; the feathers 
on the sides of breast and belly streaked with black . Length about 49.00 ; wing, 20.75 ; tarsus, 8.00 (or more) ; bill above, 6.50. 
Hob.— South Florida. 
Tarsi elongated. Tibia bare for half its length. Middle toe not one-third the tarsus. 
External form, otherwise, as in A. herodias. 
Bill in the dried specimen greenish yellow ; dusky above. Entire head all round, including 
the occipital crest, snowy white ; the elongated feathers apparently not fully grown, but also 
white. Feathers of the forehead margined laterally with black. Neck ash color, with a shade 
of violet. The feathers of the middle line of the throat white, and streaked with dark plumbeous 
from a point distant the length of the culmen from the base of the bill. These feathers on the 
throat, likewise, have a wash of rufous. The upper parts generally are bluish gray, the elonga- 
ted scapulars much paler. The under parts generally are white ; the feathers on the sides of 
the breast are bluish black, streaked centrally with white ; those of the sides of the body streaked 
on one side with the same. The sides of the body are like the back. The edge of the wing 
and the tibiae are purplish rufous, with a violet shade ; the portion of the former Irom the 
carpal joint to the quills, nearly white, with spots of the rufous. The greater coverts near the 
edge of the wing are streaked obscurely with whitish, and tinged with rufous. The primaries 
are dark hoary blackish plumbeous ; the outer secondaries still darker, but becoming lighter 
towards the back. 
This species is somewhat similar to the A. herodias, but is much larger ; the bill and tarsus 
at least an inch longer. The tibia is bare for a greater distance. The head is entirely white, 
with the forehead streaked with black, exactly the reverse of the other, which has the head black
