I walk my dog at 530 in the morning to avoid other dogs. I regularly use a local school across from a birding hotspot. For 2 days, 8/23 and today 9/10, I've observed (in the dark) a bird high up in the canopy calling. I've gotten it's sound on a video, however it's very faint. It sounds like a goose's honk is the best I can relate it to. I can't imagine what a goose would be doing 45' up in a tall pine, so I doubt it's that. We do have sightings of rare birds for the area, so any ideas are welcome. I can look up sounds from the ideas to make a match with my poor audio and memory. Can anyone point me in the right direction? Thank you!
