So glad to see you post and to have started the other thread. I learn from folks like you who are more knowledgeable and more astute observers than am I. As an example, I think it was you who a year or so ago posted about a junco/white-throated sparrow hybrid and maybe posted a picture. At the time I had no idea they hybridized. Juncos are so common here in winter I had never really tried to closely observe them.    Since that time I have watched them much more closely, am so much more aware of how variable they actually are in appearance, had never really noted the differences in males and females, and occasionally wonder if I am looking at a hybrid or just getting familiar with their variability. I took them so much for granted that I don't think I had ever picked up the binocs to look at them and notice the difference between males and females. I appreciate them so much more. Thank you!
