Possibly a starling pair? These birds usually breed earlier and do build their nests in such places. Very aggressive birds.

Your username indicates you are in Iowa; is that where you saw this bird? It does resemble a 1st-year male Orchard Oriole.

Where are you located? Can you describe the sound it makes? When you say "night"......is it completely dark out? What time of night? To start with, check out the sounds that a mockingbird makes. sometimes they sing at night.

The second photo I saw of this bird looked really familiar. I think it is a cardinal bird. Some times I saw this bird, my friends told me it was a cardinal. This picture looks pretty good. Where did you take it? Local or a place of interest? By the way, if I want a bird like this, can you show me how to get it?
