Great pics both but I have to go with the female bluebird since I've been a bluebirder for 22 years now.

I wish you could have shot a picture of one of the most interesting bird poses I have ever seen a few years ago. A male bluebird, male cardinal and male goldfinch were perched on the rim of my birdbath in perfect 120 degree arcs staring each other down. What a brilliant scene of bright blue, scarlet red and bright yellow.
