Bird Survey: Tampa Bay NWR, 10-14-16



We surveyed the seven islands in the Tampa Bay NWR




Snowy Egret approaching a school of baitfish




This juvenile Snowy Egret is using its feet in an infrequent feeding technique similar to that used by Black Skimmers with their bills.


They will drag their feet along the surface of the water 




and when the baitfish come up to investigate the disturbance, they become its meal.


and sometimes it turns out to be a shrimp instead!

A group of Sandwich Terns are collectively known as a "hogey" of terns










Anhinga
 Note the sharp, spear-like, pointed bill which is used to spear fish



These birds are frequently seen soaring high in the sky overhead.   They are very graceful fliers and can ride the winds, traveling long distances without flapping their wings.


Double-crested Cormorants
 Compare their hooked bills which are used to grab prey fish with the pointed bills of the Anhingas which are used to stab prey fish.





These cormorants often stand in the sun with their wings spread out to dry.  They have less preen oil than other birds, so their feathers can get soaked rather than shedding water like a duck's.  Though this seems like it would be a problem for a bird that spends its life in the water, wet feathers actually probably make it easier for the cormorants to hunt under water with agility and speed.
