A
partially leucistic individual paired with a slightly leucistic
individual at Compass Point, St. Thomas, 18 May 2003. Photos © by Floyd
Hayes. When first seen (photo A), the bird on the right was suspected
to be a hybrid Zenaida Dove × White-winged Dove (Z. asiatica).
Ten White-winged Doves were present in the area, where breeding was
suspected. Subsequent photos revealed extensive white on the inner
primaries and secondaries; in White-winged Dove, white is limited to
the greater coverts and tips of secondaries. Note that the extent of
white is fairly symmetrical on both the left (C and D) and right (B, E,
and F) sides. Also note the narrow line of white near the carpal joint
(A-C). The more normal individual appeared to have excessive white on
the tips of the secondaries on the right side only (A and F) and
appeared normal on the left side (D-E). Both birds appeared to be
moulting.
