Monday's Results

An incredibly slow day of banding with only 10 new birds banded and 7 recaptured of 14 different species.  Moderately strong south winds prevented good migrating conditions, so I was not surprised by the low number of birds banded.  The highlight-of-the-day was an adult female Baltimore Oriole with an unusual bald spot on the top of her head.


Baltimore Oriole (After hatch-year, female)

Last year on October 1st, we had a capture rate of 79.7 birds/100 net-hours.  Compare that to our current capture rate of 58.7 birds/100 net-hour and we get a difference of about 20 birds/100 net-hours.  That translates into a decrease of about 100 birds per week from last year or about 700 birds behind where we were last year!  We have had a mild fall so far with only a couple of major cold fronts making it this far south.  Couple that with lots of days of unfavorable winds for an east coast banding station and you get the results I described above.  It just goes to show how seasonal weather patterns affect bird migration.
