There are many anhingas at audubon park at this time. I never see them congregated, though. I always see them separately, which is very different from the cormorants at the park. Maybe I can get a picture of them, too.
Inmaduro, pico naranja, sin collar blanco, rabadilla oscura y plumas caudales centrales blancas.
The order Suliformes (dubbed "Phalacrocoraciformes" by Christidis & Boles 2008) is a proposed order by the International Ornithologist's Union. In regards to the recent evidence that the traditional Pelecaniformes is polyphyletic, it has been suggested that the group be split up to reflect the true evolutionary relationships.
