I camped out off Brewton Road near Colockum Pass for the first night. Falling asleep to the sounds of distant lowing cattle. In the morning I awoke to the mellow “poor-will-low” of a Common Poorwill and the distant “peents” and later the croaking “booms" of Nighthawks. Both Poorwills and Nighthawks are crepuscular members of the Nightjar family. I’ve gotten used to hearing both for a short time after everyone else has roosted for the night or just before dawn, but until recently I hadn’t been able to readily identify either. I like to think of Poorwills as the alarm clocks of the scrublands: I always hear them first, and the chatter of other morning birds always starts as an annoyed “wassat?” shortly after. Fun fact: the Common Poorwill was the first scientifically-identified hibernating bird, although the indigenous Hopi peoples knew it for far longer and called it “hölchko” or “The Sleeping One."
As mellow as the Poorwill is, the Nightjar loudly makes its presence known, not with calls or song, but with loud croaking “booms” made by its wings when pulled in for a dive. When I first heard Nighthawks in the field I thought it was a sick Raven or aggressive distant bullfrog (flying bullfrog?). Indeed, they are sometimes known as “bull-bats” as they often are found feeding in the dark with the mammalian fliers.
Other singers throughout the chorus include Juncos, Creepers, Woodpeckers, Yellowthroats, Chickadees, Swallows, Sparrows, Waxwings, and even a daylight-confused Owl around the 28 minute mark.
