The audience of egrets

These little egrets (Egretta garzetta) must represent a show for the yellow-bellied slider turtles (Trachemys scripta scripta).
During their peaceful activities, lay to sunbathe on a branch, they were attracted by the white plumage of the three birds and they stretch necks and bend heads to better enjoy the show.
But the egrets have not attracted the curiosity of the turtles only. Even a Purple Swamphen (Porphyrio porphyrio) and a photographer have turned their attention to them.
