The Bare Throated Tiger Heron from Costa Rica's Pacific side. An easily spooked species. Required stalking/crawling in the tall grass.. seems like it was a cat and mouse game until he lifted out of the grasses and settled into some preening action. These herons are hunting machines, as it wasn't long before he was in the grasses again,with his head buried in the weeds.
