Birds (but no Bees)

These birds have built a nest in a pot we have on our side door for the past several years. Actually, they may have been absent last year, but they're back this year. If you can tell me what kind they are, please do. Oh, and I say "birds", but you only see one in the video (shot with my phone). They take turns--the other one hangs out by the deck railing. I guess he (or she) is the lookout. Anyway, here goes:

This was the third video I shot in a span of about 5 minutes. I stood very still on the inside of the door. In the other two videos you see mostly pot but no bird. As they say, third time's a charm. I guess the bird got a little used to me by this time.
