Green Heron - Cardenas, Nicaragua

There were several of these herons working the margins of the pools just around the bridge in Cardenas that crosses Rio Sabalos. These herons are always weary and show it when the flick their tail. Once settled in, they have laser focus and will sit staring at the same patch of water for what seems an eternity. I have also watched this birds use bait to fish. smart critters.
