Perhaps a mulberry.
Abelmoschus has opposite leaves so rule that one out.

Compare to link below.

Here is a link that might be useful: Mulberry

I agree with a Mulberry...fast growing WEED

Thanks for the help, this is definitely an area where there has been birds congregating in the past, so mulberry fits I think.

It was interesting seeing the volunteer plants this year, a jalapeno plant, some sunflowers, squash, and a few others.

People ask about apparently quite abundant Morus alba seedlings here repeatedly, with the characteristically diverse leaf shapes of the species being a cause for confusion and disagreement. There is a tendency for young plants to have deeply lobed leaves while more developed examples may display few or no divisions.
