Any one know of tiny bird with beautiful song and unusual next.?

For those of you answering my question about the tiny bird with the most beautiful song, the answer is somewhere in the birds nest. This is a large solid 8 inch length football shaped nest. It has an approx. 1and1/2 inch circular opening as it's entrance to the nest. The tiny bird has been built in one of my hanging geraniums on my patio fence.

it sounds as tho you may have a house wren. they are tiny and have a pretty song and build close to peoples house. i had one build a nest in my basement once when i left the door open.
