The recording begins with a series of calls given by the adult Northern Goshawk, which I presume is the adult female.The Canada Jay is first heard around 14 seconds in, and then they start calling repeatedly at 32 seconds. At 52.7 one of the Canada Jay gives the first imitations of the Northern Goshawk, with the goshawk calling again at 1:04, and then a second goshawk calling on top of the other at 1:07, which I presume is the male given the slightly higher pitch with an almost Osprey-like quality to the calls. Almost throughout the recording, a Ruby-crowned Kinglet gives agitated calls from near the goshawk. Also Broad-tailed Hummingbird, Mountain Chickadee, American Robin.
觀察細節
Amazing encounter with a pair of adult Northern Goshawk. I first heard two Gray Jays giving agitated calls and then saw an adult Gos come low through woods. For the next ten minutes the jay and the goshawks called frequently and I was able to get some recordings. I believe the first bird that I saw well was the adult male because it was very pale gray below with almost no barring, one of the cleanest individuals I've seen. Later I saw a bird that was more heavily marked.
