These presumed Siberian Gulls (Larus
heuglini) were photographed at Halileh/Bushehr Bay,
on the central Gulf coast of Iran in Late February 2000 by Philippe
J. Dubois:
I do not feel able to comment on the immatures:
- but the adults in this photo are, in IMHO, a male normal heuglini
on the left, with a female (thus smaller) "Big Pale Heuglini"
on the right: note that on the
suspected "Big Pale Heuglini", the P10 mirror
is much larger than the normal heuglini, with the black
subterminal band about half the width of the mirror, and the tail
tip falls under the apical spot of P6:_______
- very like the odd Texas gull (also note the head and bill shapes):
note that on the
suspected "Big Pale Heuglini", the P10 mirror
is much larger than the normal heuglini, with the black
subterminal band about half the width of the mirror, and the tail
tip falls under the apical spot of P6:
