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.

Which yard lifer is it?

Gonna need some help on this one, boys. After scoring another flyover BOWA by microphone today (https://soundcloud.com/user9140545/bowa-kentwood-4-march-2013)

I subsequently had another finch flyover which I immediately thought was most likely CORE. I then waffled (on SETI's advice) about WWCR, but now am confused. Please listen and advise:


Here is the sonogram of the loudest of these calls. Note the peak at 7 kHZ and the pattern of the call, and compare with sonograms for both CORE and WWCR here:


Thoughts? (either way it's a life yard bird)


  1. That's tough, but I'm inclined towards redpoll. Specifically HORE :>

  2. no thoughts -- happy to leave it unidentified.

  3. I have no doubt, certainly a redpoll.
