Enjoy a stroll along this coastal estuary and bird hangout.
Crakes, Coots, & Gallinules are three varieties of a diverse family of birds, many of whom are associated with wetlands. Observe carefully from the right side of the fence.
You might see some American Coots near here, but the other varieties are usually found in other climates. Coots have prominent frontal shields or other decoration on the forehead, with red to dark red eyes and colored bills. Many, but not all, have white on the under tail. The featherless shield gave rise to the expression "as bald as a coot," which the Oxford English Dictionary cites in use as early as 1430.
Our fluffy team of ornithologists have researched the call of the American Coot by carefully listening to recordings at 3/10 speed. They found that it sounds something like:
We hypothesize that these odd sound patterns are a way of communicating their location within the slough area. Clearly more research is needed.
Congrats to old bald coot Golfer01 for being first to find!
