Caleb's Presentation and a Great Field Trip


We had so many good birds (Carolina Wren, Red-necked Grebe, Common Redpoll, Red Crossbill) on our November 17 Field Trip that we posted the report and photos on our Recent Sightings page.

Regarding Caleb Putnam's November 15 program about night bird migration and how to build a recorder for $200, here is his follow-up email:

Hey Ric -

Here are the links we discussed:


Mic (completely preassembled and with preamp):
http://www.oldbird.org/21c.htm

Sound capturing freeware (for recording birds via the mic and viewing the sonograms):
http://audacity.sourceforge.net/download/

Raven (software for advanced sound analysis):

Think that's it!
