A bunch of Type 2 flight calls (flying away from red pine tree). Juvenile calls are the loud tinny calls that show on the spectrogram as inverse check marks.
Деталі спостереження
Group of nine feeding on red pine cones in a few trees, then flew away (saw all at once, until then would have guessed 4 RECR). See audio, calls with lightning shapes. Confirmed by Tim Spahr. The loud tinny call in the 3rd audio (upside-down checkmark on spectrogram) is definitely a juvenile calling, per Tim. Also, one male RECR feeding on red maple buds in a nearby tree. RECR typically start wandering in early May but I think the juvenile is local, as Type 2 RECR have been around southern and western Maine since late summer and multiple ones have been documented breeding this spring in areas of red pine and areas of pitch pine. In quite an unusual occurrence, they have been more common this spring than the Type 12 Northeastern RECR, at least where I've been.
