Observation details
juvenile "cat call", a few times, followed by an adult call, then alternating, ending with just adult calls. 2:42 a.m. Aug 19th at the camper N of Valeport. then around 5:30 a.m. adult call only from within the campground for a few minutes. Discussed with Dan Z, and played him the video, he's quite sure the part of the meow call is of a young. Two questions: One question was: is this a young with a type of begging call, with an adult, and alternating. Or is this a young call AND a young doing the adult call... when are the young capable of an adult call, at what point can they do both? I checked Bird of the World: "Vocalizations of owlets in nest rapidly increase in intensity, loudness, pitch, and character. Juvenile males mimic adult hoots during their first winter, but the calls peter out in gasps, gurgles, or squawks before completion. First complete hoots by captive juveniles in Ontario not before Jan; deep male tune seldom realized before spring" So with that, this would be a young and and adult. Second question, what is a young doing with the adult so late in the season: Dan knows from at the farm that young who are not successful at hunting will keep close to the adults throughout the summer, begging for food. Discussed with Dan S: entering as 2 birds young and adult.
