American Bittern: Master of Camouflage

Written by Bob Sundstrom

This is BirdNote!

[American Bittern’s “oonk-a-loonk” calls, repeated]

One fine spring morning as you walk near a marsh, you are stopped in your tracks by a loud, reverberating call, with a cadence that seems lifted from an old cartoon soundtrack.

You scan the cattails, but it seems this comical sound has an invisible source.

Then, after a long moment, into an opening in the cattails walks what looks like a good-sized heron, but with a mottled brown back and bold brown stripes running the length of its very long neck. You are looking at an American Bittern, a member of the heron tribe that spends much of its time in the dense cover of the reeds. Bitterns are masters of camouflage. Not only does their striped plumage perfectly imitate surrounding vegetation, but for further concealment, they freeze, holding their heads and necks upward at an angle that mimics the reeds.
