May 15, 2010 GRANDVUE

Did a birding hike in the AM before heading to Maryland. Tree Swallows are on nest. I opened the box (#2) and the female would not flush. The male did several dive bombs so I think eggs are being incubated. I will check again to see young. Birds observed: Baltimore Orioles in abundance and one female building. I saw what appeared to be an immature oriole with a nervous parent. I thought this to be a bit early, but could not account for any other reason to see such behavior. Also had yellow warblers, wood thrush, bluebirds, indigo buntings, and a long look at a hooded warbler singing repeatedly. Heard rose breasted grossbeak, scarlet tanagers, red starts, veery thrush, and many more. good bright day.
