The birds ate the seeds on the tassels, I don't know if the corn is pollinated or not.
Will the corn grow new tassels, or do I need to plant new corn?

Thanks!

Not sure what you mean by 'ate the seeds on the tassels'. What color were the tassels before being consumed by birds? Not sure but I think (at least in field corn) tassels go dark once used as a conduit for the pollen.
You could always open an ear and see if there are developing kernels, if so, you should be ok.
