Great Backyard Bird Count and Birds and Barometric Pressures etc...
First off, don't forget that the Great Backyard Bird Count (GBBC) starts tomorrow! It takes as little as 15 minutes and is quite enlightening... don't miss out!!!
Next up... Back on January 22nd, I started wondering about bird activity and the barometric pressure (and the weather etc.) Was there any sort of correlation? So for the last 25 days I've been making quick notes on feeder traffic, and today, I looked up the atmospheric conditions for those days using the wunderground site. What follows is more or less self-explanatory -- my location's weather charts (in color) for Jan and Feb followed by my own charts (black and white) for observed bird activity. Take a second and it should all make sense...
Wasn't that exciting? (Before I go further, just a word about these charts and this 'research'... The stuff above is wildly unscientific: the sample size is miniscule, the observations are subjective and uncorroborated, and the initial objective was a blur to begin with. That being said, about the best we have is a 'hmmm study'.) The only things I find even slightly compelling are the activities around Jan. 27 and 28; and Feb. 11 and 12 -- when the barometer tanked (or was about to tank), the birds seemed to be riled...
As I said, not very scientific, but fun nonetheless...
