Claudia, Brr, sounds like it's gonna get cold where you are! Stay warm and thank you for feeding our feathered friends to assist them through such cold temperatures! Love your pretty pictures! There sure is a big difference in the sizes of Flickers, Red-bellied WP's and Downy WP's. The Downy is quite small. The photo showing the sparrow taking off is so cute and that is one really beautiful shot of the Blue Jay!
