Bird nest identification

[Mitsubishiman]

This is for anyone that can help, bird nest in a red elm tree, my backyard, northeast Iowa. Seems to be constructed of only leaves, I have lots of birds however did not notice this until today.

Not something I normally see, not sure which bird, or what builds nests out of leaves.

Could be squirrels

Never thought of that

It is a squirrel's nest as previously stated
