Hi Tony,
I think Peter is correct. I’ve had a closer look by magnifying the picture and it looks like the tip of the tongue is bent downwards rather than it being forked. In general, the tongue of large raptors is deeply grooved longitudinally. I suspect that assists with directing body fluids of its prey items (e.g. blood) and drinking water down the throat.
Kind regards,
Stephen

Can’t puzzle out why the bird pictured (seen at TownCommon Cons. Pk. yesterday appears to have curved forked extension to tongue.
Help!
