Saw four Least Terns at the "wildlife viewing area" on the North Tract of the Patuxent Research Refuge this morning (7/10) at about 0830. Does anyone know if they nest on the refuge or anywhere in the area? Lots of other good birds too, including Kentucky warblers & 6 other warbler sps, both orioles, both tanagers and Blue Grosbeaks. This was in just about an hours worth of birdwatching at the viewing area and the River Trail. Tom Beal Glenn Dale,MD
