-- More Flap-Rate Analysis --

----------------------------------------------------------------------------------
For those intrigued by wingbeat data of Pileateds vs. IBWO I'll refer you to this graphic analysis posted by Bill Pulliam:

http://bbill.blogspot.com/2006/07/woodpecker-wingbeats-without-comment.html

I'm somewhat agnostic about wingbeat analysis given the small sample size available and many uncontrolled variables involved, and Bill himself similarly cautions against reaching hard conclusions, but each piece of analysis is worth a look, and as with Cornell's analysis, Bill's graph indicates the flap rate for the Luneau videotaped bird possibly outside the usual range for a Pileated.

(p.s. -- I'm breaking my own self-imposed rule-of-thumb here in even making reference to the Luneau video which has been beaten to death.)
