Mid-morning today (Sat 5/5) a brief but excellent look at a Prothonotary Warbler at the start of the Silver Spring trail just below the solar array. There is a set-up for mist netting on the right side at the start of the trail and the bird was near that spot. Bird dropped down and I could not relocate. Wanted to get the word out for anyone on the lower Cape. Otherwise,very little in the way of migrants at the sanctuary this morning.
