Rain off and on through the night and morning. Quite a bit of activity in the early hours of the morning. I can’t decide whether the calls were from Gulls, Otters, or both.
Mystery Calls: These calls started around 4am, and continued off and on for the next couple of hours, at least. I have included three different clips. Mostly they sound like gulls to me, but I am not sure why gulls would be out and about this early in the morning (well before daylight). Some of the calls are slightly more reminiscent of River Otter chirps, and I am unsure of the range of otter vocalizations, so perhaps they are otters.

It didn’t start out windy yesterday night, but the wind picked up during the night and seemed to blow as strong, or stronger, around the house as it has on any of the previous nights. Forecasted windspeeds were lower, so perhaps the direction was more conducive this area to feel the full force of it.

Mystery Call: I suspect this is a River Otter. It’s in the same frequency and has a similar tone quaity to the chirps, but it’s more drawn out. There are two vocalizations with a car driving pulling away in a nearby gravel parking lot between. Recorded at 22:33. Download Mystery Call

Mystery Call: I have no idea what this call is from. It was quite faint, and may be difficult to make out above the noise. I have included an additional clip which has had a noise-removal filter applied. I think the call is more or less intact, but there are definite artifacts in the background.

Mystery Call: This is a very short clip of a single call. It sounds most like a peep (the collective term for several species of small shorebirds), though I do not know why one of those would be flying around here now. Recorded at 00:58. Download Mystery Call

River Otter and Mystery Sound: Another clip of river otter chirping in the distance on a windy evening made more interesting by some strange high frequency sounds. I do not remember noticing them when I first went through the recording, but I cannot figure out how they would have been introduced during a simple copy/paste operation. I have included a Spectrogram of the clip to show how the mystery sounds extend out of the frequency range I can easily hear. It seems odd that they go through each channel sequentially, but I am at a loss to explain why that might happen. At this point I am thinking it’s most likely some type of interference, though perhaps it is biological in origin. Download River Otter and Mystery Sound

Another windy night. Caught some Raven dialog this morning. Maybe someday I’ll learn what they’re talking about.
