I agree with Liam.

There are two different species here, Red-bellied Woodpecker (Melanerpes carolinus) in the first two, and Yellow-bellied Sapsucker (Sphyrapicus varius) in the last three. I suggest splitting the two series into two different spottings.

the Last Tree picture is : Ladder-backed Woodpecker

I think that the last three pictures could be sap sucker,based on their contour.

So two different or all same kind?

I think no red under the chin makes this a female. Some good pictures here:

nutalls are smaller than robins and bigger than phoebes.

This is more than one species on a single spotting. The first few pictures look right for Red-bellied woodpecker. I think the last few pictures are Yellow-bellied Sapsucker.

Good shot,i like it!
