Last night, while sitting on the roof and talking to Curtis, amongst the hundreds of seeps, SWTH, and occasional GCTH flying over, I heard (and recorded) a low, dry buzzy note. In the recording, you can hear me say "Whoa, buzz note. Holy crap, that sounded like Dickcissel! Curtis, I think that might have been a Dickcissel." It was a noticably dry note, lacking any of the piercing, metallic/high=pitched quality of INBU, etc. I figured it either had to be BLGR or DICK, or something else not expected in my yard.
So, this morning, I anxiously analyzed the recording to see what I could do with it. The bird was pretty high up, so that it was barely picked up on the sonogram, but it is there, and most critically, the frequency range of what's visible is in the 2,800-5,500 HZ range only. The duration is around 0.08 sec. Basically, boys, what I suspected at the time is confirmed. None of the other buzzes are this low-pitched, and I judged by ear (immediately) that the sound quality was way too dull/dry for INBU. So, Skyler, enjoy losing your lead back again!
2013 and beyond
It's pretty simple: the most birds seen or heard from one's yard during 2013 will be the "winner". Want in? O.k....then do it despite that.
2013 promises to be a lot less mean but still a carbon-free birding competition, even if slightly less exciting than a MEGA x EPIC hybrid.
