I was with Mike Bowen at Hughes Hollow about 11:30 this morning when he
spotted a single Tree Swallow flying over 1st impoundment on the right.
Definitely my early date for this species in Mont Co. And 10 days earlier
than the current early date in eBird for Montgomery, 2/26, which also
happens to be an observation of Mike's from 1998.
