BIRDS — AKDEIDAE ABDEA. 
GG7 
HERODIAS EGRETTA, var. CALIFORNICA, Baird. 
Ch. — Pure white. Larger than H. egretta. Length, 43 inches ; wing, 17 ; tarsus, 6.70 ; bill, 5. 
Hab. — Coast of southern California, and perhaps the Rio Grande of Texas. 
This bird is very similar to Herodias egretta, but is considerably larger ; the tibiae are bare for 
half their length. The feathers of the back are not fully grown out, so that I can make no 
comparison in this respect, but the scapulars are more elongated and plume-like than in the 
other species, and there is a tendency to the same along the belly. The bill appears of a more 
brilliant yellow, dusky only near the tip above. 
It is possible that this may be only a variety of the R. egretta, but the size is so much greater 
as almost to warrant its specific separation.
