Hi Meghan,
According to last years posts my first male arrived on May 4, yours on May 5, but, after a one day flurry on May 10, neither of us had regulars until after May 16. It looks like the winds will become more favorable by Wednesday (May 15) afternoon so I really hope to see some activity during the next few days. Btw, I will be close to the GBH rookery this weekend; is it still worth visiting?
