I have a Mulberry tree out back in my neighbors yard and it has the birds in a frenzy and they are all taking out their frustrations on my car if it wasn't for all this rain I would be washing my car every other day.
I work on the Lehigh and have never seen the carp in a frenzy. There is an impoundment near my house and the carp get in such a frenzy that you'd think you were fishing for reds in LA.
