Anhingas at Sawgrass Lake Park: 2-26-18




Different fishing techniques between the Anhinga 
and the Double-crested Cormorant


The cormorant has a hooked bill and “grasps” its prey, turns it head first so the spines are pressed against the fish’s body and then swallows its prey.





In contrast, the Anhinga’s bill is sharp and pointed and with their long, flexible neck, a fish is speared.  The Anhinga then throws its head back flipping the fish into the air.  He catches it and maneuvers it so the fins are pressed against the fish’s body.





then Gulp and it’s gone!



Although the anhinga has a functional oil gland (like most birds) on its rump that produces the substance used to waterproof feathers, the anhinga’s feathers are three times more “wettable” than the feathers of other aquatic birds.  This allows them to swim underwater easily but requires them to dry the feathers between dives or after they finish diving for the day.







After finishing its fish n chips (minus the chips), it’s time for preening those all important feathers




Now it’s time for the male to display to the female who is several feet below him on a lower branch.





She (on the left) must have been impressed as she flew up to join him.




Duel sky-pointing




Many gyrations





“Swooning"

This courting display went on for quite a while before they flew off to perhaps continue the more intimate details in private.
