Spr. Cu—Head smooth ; bill yellowish to the tip; feet black. Color pure white. Length, 39 inches; wing, 15.50; tarsus, 
5.70; bill above, 4.70. 
Hab.—Southern portions of the United States ; straggling to Massachusetts. 
Bill, with the culmen and gonys about equally curved, the commissure slightly concave near 
the tip. Legs slender, elongated; middle toe about three-fourths the tarsus. Tibia bare for 
about half its length. Head without a crest; the feathers lying close. Lower part of the back, 
in the breeding season, with a series of elongated feathers, with stiffened shafts, the plumulae 
distant and elongated. These feathers are gently pendent (not recurved) and extend beyond 
the tail by about its length; théir total length is nearly three times that of the tail. The 
feathers of the lower part of the neck but little elongated. 
Color entirely white; feet black; bill yellowish, dusky above, (in 9298.) According to 
Audubon, the entire bill and the iris are yellow. 
This species appears to differ from the European JL. alba in lacking a black tip to the bill, 
which is five inches long, not six; the tarsus is about six inches long, instead of eight.
