You're not alone @Charlie Spencer. My eyes glaze over on a lot of aspects of birding, most of them are subjects I don't understand, but I have no interest in putting any effort into changing that. Gulls are one example of where my eyes glaze over long before I learn any of the deeper knowledge needed to properly ID them. When I see an unknown Gull, my eyes glaze over, I call them Gulls, and I move on. π€·πΌββοΈ I am content in knowing that I don't have the memory power required to memorize all the little details written about every bird I've seen, or might see. Let's face it, memorizing all the little details is a big part of getting good at IDing birds. That memory requirement increases when you get into IDing sub-species, and/or Gull cycles, and such. Trying to retain too many details just clouds my already foggy brain and gives me that glazed eye look. π₯Έ
