Re: almost perfect cach x tatus?
I can see where you are coming from, Lou, but I am not convinced that this is not a Herring Gull.
Re: almost perfect cach x tatus?
Keith had his gull brought to Birding Frontiers (Martin G.) today, where I commented it as follows.
Hi Keith.
Funny you should bring this up as I just considered to do the same – meaning showing your gull as an example of what I belive could as well prove to be a pure Herring. I can however, see where Lou (on BF) is comming from – when he claimes Caspian involment. It´s imoportant to realise how variable a Herring actually can be, thereby not saying that the whole range of variability is perfectly known to us, or for that matter, easily excluding possible hybrid origin for certain individuals. Keth´s gull doesn´t strike me as a hybrid in the first place since it would be difficult to exclude a pure Herring.
