Arnold Arboretum 5/7

From Bob Mayer:

Marc Devokaitis and I had another big turnout of more than 30 birders of mixed experience for a walk in the Peters Hill section of the arboretum. Weather was lovely despite the forecast and the group had good sights and sounds of a variety of birds.  Nice to see a pair of bluebirds going in and out of a nestbox at the top of the hill.  The full list:
