I came upon this Royal Tern (Thalasseus maximus) one sunny afternoon. It didn’t seem too concerned about my presence as the ablutions continued unabated for at least another ten minutes.
This is one of the largest tern species in my area. Easily differentiated from the similar Caspian Tern by the bright white forehead which is visible outside of breeding season.
The Latin binomial translates as sea greatest (though personally, it’d make more sense as great of the sea).
