Male Turkeys or "Toms" as they are called when mature are in a breeding mindset in late April and very competitive. This Tom encountered in the Okefenokee National Wildlife Refuge gives the classic pose and gobble-gobble-gobble call and displays a nice long "beard". They also typically take on humans this time of year, in this case challenging the van to a little footrace. Often they will attack their own reflections in cars when their hormones are on full boil.
