Why doesn’t he jump in the water to cool off?
I don’t think it would do much good to jump in the water. I haven’t taken the temp of the water but I’ll bet it’s in the nineties. I suppose, though, that it would be better to be wet and cool off through the evaporation of the water.
Apparently panting is the most efficient way to cool down since birds, like dogs, don’t have sweat glads and must pant to cool off. The throat on the heron in the photo was pulsing (you can see that it’s expanded in the photo). This gular pouch dissipates heat through the abundant capillaries in that region.
