Both Sapsuckers were immatures so I'm not sure if they were males or females. The first 3 photo's are of the same bird.
This one is larger with a more prominent white stripe running from the beak down the neck. Since then I haven't seen the smaller Sapsucker, only the larger one. They are quite skittish so I was lucky to get the shots I did. Everytime the see me they take off.
I am amazed how much the birds like the peanut feeder! Wish I had bought one long before now.
