CORRECTIONS AND CHANGES SINCE 1880. 
PANDION HALI4TUS CAROLINENSIS. (Gmel.) 
This osprey is common in the Bahamas. Mr. Maynard has 
described the Bahama bird as P. rédgwayc; but in a series of 
specimens I find no differences sufficient to warrant its separation 
from birds fromthe mainland. 
ARDEA CYANTROSTRIS. Cory. 
In originally describing this bird as new, I considered it distinct 
from A. tricolor ruficollis from the totally different coloration of the 
bill and legs, supposed to occur only in the breeding season. Since 
that time similar specimens have been taken in the winter season. 
A. tricolor ruficollis undoubtedly assumes a yellow bill during most of 
the year at least, even if Audubon was wrong in his statement to 
the effect that it had a partly yellow bill during the breeding season. 
It is probable that the two birds are identical, but it is also possi- 
ble that the Bahama bird may be distinct; and colonies occasionally 
wander to Florida, where it has been found breeding. This-would 
account for the blue-billed specimens being taken in Florida, and 
would not prove its identity with A. tricolor ruficolles.
