Day 320: Yellow-billed Cuckoo

Yellow-billed Cuckoos are found through much of the central and eastern United States. They are furtive and retiring by nature and are often first revealed by a loud, hollow sounding call. Yellow-billed Cuckoos have the nickname of "Rain Crow" because of their apparent tendency to call more frequently on cloudy days, although their proficiency as predictors of weather has never been demonstrated.
