Houston Audubon Smith Oaks Sanctuary at High Island, TX. This is an outstanding place to view several types of herons, and cormorants nesting.
The egrets are especially spectacular in breeding plumage. The long filamentous feathers (aigrettes) were nearly the cause of their extinction a century ago, as they were in demand for ladies hats. Egrets were slaughtered on the breeding grounds for these feathers.
The Great Egrets are most numerous and well into nesting. When the pairs meet at the nest they are obviously excited. In this photo you can see that they both have the small feathers on their necks elevated (hackles up), something I had not noticed before.
Although Roseate Spoonbills are beautiful at any time, in breeding plumage their heads are more strongly patterned and their tails and wing feathers more deeply colored.
