Hi Everyone, I have been a birdwatcher in the US for 40 years, and am fairly accomplished. But of course there are great new things here. Perhaps you can tell me what I'm hearing. After significant rainstorms I often here a creature, at night, that sounds like a jackhammer - a deep penetrating sound that carries. These do not sound like the various frogs that emerge after a rain. I have a video on my phone taken at night (black/blank video with sound) for someone really curious.
