Age ID of a Caspian Gull

Post by WolfgangSchweighofer » Fri Jan 13, 2012 4:28 pm

Hi,

its the case of a bird mentioned already here:
viewtopic.php?f=11&t=174

Theo had voted for an Ukraine ring and he is right. I have found the only Ukraine T-ring on the KULING website and after comparing several details I´m sure: it´s identical ;)
Further on I´m sure (with 2 pics) that the ring number ends with ...02856, so the complete number should be T002856.

Today I´ve received data from Kiev RC, producing a CG born in 2006 at Kanev reservoir. So everything OK - but: Can that be a 5cy CG? I would n´t have expected that yellow feet and bill without any dark markings?

What do you say, dear CG-experts?

Wolfgang

hi wolfgang,

a 4th cycle cachinnans can well look totally adult. bare parts colour has also something to do with its metabolism (hormonal things) as far as i understand. and certainly by mid january some individuals get their "alternate" look.
