Hi all,

        Birded 2 hours this morning along the hiker-biker trail in Rock Creek Park;
Best bird of the morning (10-12am) was a male Cerulean Warbler singing and  foraging high in a Sycamore tree just off the path.  He might be a possible breeder;
I watched him for 45 min. he stayed in an area of 4 trees. Since they are becoming so uncommon, it is nice to see one.
