Last night I was fortunate to hear a duet by two birds with unusual names: Chuck-will's-widow and Whip-poor-will. The names of these nocturnal birds are imitations of the sounds they make. In other words, the names are onomatopoeic. The birds actually do say, "chuck-wills-widow" and "whip-poor-will." South Dakota is at the extreme northwest corner of these birds' normal ranges, so it was a treat for me to hear them--especially since the Chuck-will's-widow was a new life bird for me, number 345. I don't have any photos, but the sounds these birds make are far more interesting anyway. Here is a link to a Chuck-will's-widow calling:
and here is a Whip-poor-will:
