the morning was spent having brunch for brothers birthday
so arrived at the tarn about 1130
first bird i noticed was very striking, i stupidly called this a caspian,but the more i watched it i had some doubts
gull sp
saturdays caspian
thinking the light was playing tricks i was happy with caspian until i started to go through the photos later
this was the ones that made me think
very much a hybrid
a reply from lou
hi Darrel,
this 3rd cycle bird is not a Caspian Gull, on multiple traits like lack of large pale tongues, very small mirrors, no p4 marks, swollen and blunt bill tip. but what is it actually? that's not so easy. Yellow legs seem to suggest a YLG, but many things are wrong for a 3rd cycle michahellis, e.g. browish tertial centers and again, lack of a p4 mark, also the strongly immature character of this bird. So we have to look for a hybrid combination. My best guess is LBBG x HG for this bird. Short yellow legs and red orbital ring are pro LBBG, also the darkish mantle much black to p6-10. lack of a p4 mark, just a narrow p5 subterminal band and brownish tertial centers as well as largely brownish hue on greater coverrts probably are due to HG parentage. A more remote possibility would be a cachinnans x argentatus but that is quite unlikely with this combination of characters (just the dark iris would be ok). Another possibility is michahellis x argentatus.

i feel the bird has some caspian gull genes in it ie head shape and dark eye, along with the neck markings
very educational bird
jackdaw
rook
common gull
herring gull
