This Green Heron (Butorides virescens) and I surprised each other early one September morn. I was recording a nervous Moorhen and walked right under the Heron before either of us noticed. This is the sound he made as he took flight from his Willow perch and flew away.
Green Heron (Butorides virescens) This is a sample to compare to North American birds. I found a little marshy area 10 miles north of Quepos (Costa Rica) that was absolutely full of Green Herons and Northern Jacanas.
Butorides sundevalli is not the primary subject of the video clip; the primary subject is Grapsus grapsus (Sally lightfoot crab). Eastern Pacific Ocean, Duration 13 seconds
