Marsh Wrens are about the size of a sparrow. They’re a rusty-brown color, with black and white markings that resemble eyebrows. These were recorded at Kennedy Park, in Napa. Listen carefully and you’ll hear a quick couple of “chuck” sounds, followed by the Marsh Wren’s “rapid fire” song.
Tune into KRCB.org (104.9 FM Sonoma County) to listen for the current segment. Ear to the Wild is a short interstitial segment aired somewhat randomly throughout the day between other programs. They use shorts and postcards to fill airtime during breaks from Morning Edition and All Things Considered. Also during their music programing, as needed. Greta Mart tends to air them during her show around 4:47 or 5:47.
