Category hierarchy: Biomes | Water & Wetlands | Inland WatersDescription: This great blue heron is searching for prey in the waters of the Río Nigua near the turnpike. When the Rio Nigua is flowing there is no vegetation directly above it. When the river stops flowing the dry river bed still has alot of moisture so the brush grows. When the river starts flowing again it kills the brush that had invaded the river bottom since the last time the river flowed. The heron is seaching for food in the thicket of dead branches that were killed by the river as it reoccupies its channel. As an ephemeral river the river bottom is in a constant state of flux. The location is 17º59'15"N,66º17'40"W and the elevation is 10 m.Capture device: Camera: Sony Cybershot DSC W-5Original date: 20080108Locality: Latitude: 1.798750000000000e+001; Longitude: -6.629440000000000e+001

A Great Blue Heron (Ardea herodias), one of my favorite birds, complains that I've gotten too close to his perch in a Hackberry tree at the edge of Peck's Lake [Arizona]. This sample was taken at 8 pm.

Virginia Rails, Clapper Rails, Soras, Moorhens, Bitterns and sometimes Coots like to perform this act, which I call a synchophony. This happens fairly frequently when something disturbs the peace of the marsh and several birds call in response at once. In this sample a Great Blue Heron circles over and calls, and first a Bittern or Rail, then two Soras, another Virginia and finally another Sora join in the "synchophony". I have recorded instances when a barking dog, an airplane, and other rails have set off the phenomenon. I'm not sure what purpose this [chorus] serves, but it occupies a significant amount of my thinking time. It's most probably a general alarm in the marsh - A Great Blue, a dog and an overhead airplane might all be considered risks if you're a rail - and note that the participants are generally Rail-family birds or birds with rail-y behavior, who are used to communicating primarily vocally (they can't see each other in the marsh).
