It's not just bad camera angle. He's fat no matter where he is.
If wrens could be bowlegged he'd be a good candidate. I love wrens. These tiny birds have a huge attitude with a voice to match. Loud. Very. Only the males sing the loud song, but both sing. Cornell says the male and female sing different parts, and usually interweave their songs such that they sound like a single bird singing. A pair bond may form between a male and a female at any time of the year, and the pair will stay together for life. Members of a pair stay together on their territory year-round, and forage and move around the territory together.
My mom had a wren nest in her wreath, and my friend had one nest in her geraniums. They seem to be quite social and interact well with other birds at the feeder.
That some people can look at a bird, or any creature of nature, and not understand that they have families and form forever bonds is inconceivable to me.
