In a short visit (after all, it's Mothers' Day) to Roberts sanctuary, I saw
a male Hooded Warbler in the eastern end of the sanctuary. It was singing
vociferously, and had moved to the north trail (named Bossen Road) by the
time I left after 8.
There were not many other warblers around (as has seemed the case all
spring), or flycatchers or thrushes. But I don't think I've ever seen
Caspian Tern in (well, over) Roberts before.
