Gull Guide ---We have hit a snag . It's seems that we can not provide the detail of each gull and its plumage cycle to clearly ID some of the Gulls.
so we either leave this as unfinished work(just overview level), remove it altogether, or try it finish this over time.
To finish this we need the detail provided in Shelby's guide or more. So even more research is needed..
Again== we are running into difficulties trying to put this together. So we are on hold with this development. Example of why:
See "Test Your Gull Ability" below-- For Mew Gulls they show---"dark eyes" but we have found a few Mew Gull pictures have definite "pale eyes". We checked a few other sources and it seems they are most often dark yellow brown, but some can have pale eyes.
