These season we start to serious work in our local breeding colony.
121 nest of large gulls, most (80-90%) cachinnans looking birds.
I will post in these topic photos of adult Caspian, which we measure and ringed.

Cheers
Michal

hi michal

this is great work, i whish there would be more of you in eastern europe...
PCPV has a ridiculously short bill.
PCSZ almost a fairy tale book caspian (with a slightly hanging gonys).
PCUX the famous broken p5 band and a nice grey insert in black p10 subterminal.
let them come! i'm curious how many % thayeri cachs will be among these.
do you have michs x cachs in your region???

cheers

hi lou!
yes we have mich x cach breeding (probably 2 pairs) one nest is already located.
Of course we will try to catch them too

PCPV - is not the only one with short bill, but first in our hands, more of them are present in colony.
I would like to report more of them as fast as possible, if we manage to catch them of course

cheers
Michal

Quite interesting. For me it is unclear, if real hybrids mich x cach do exist. All probably cases I have seen yet in East Germany (breeders in Lausitz area) were arg (often omissus-Phenotype) x cach.

Well done. What about the partner, chicks are real from this combination? Sorry for my questions, but I saw also MedG x BlackHG interbreeding gone in the wind, because the mother was not faithfull.
