Excellent find David. In our BCBC database we have 4 records of Blackburnians in the immediate area in July, but none during the month of June. The July birds were probably post nesting dispersal birds that had finished nesting and had left their nesting sites on nearby mountains to drop down into the valleys to forage for food. To find an active nest in the park would be fantastic considering that these birds are high elevation nesters. After reading your post I did a little research and found that they prefer to nest high in conifers, especially in hemlocks, sometimes as high as high as 80 feet, so the best bet to find a nest would probably be in those large hemlocks in the park. I hope you find one.

I staked it out & was able to catch glimpses of a beautiful male Blackburnian Warbler. This bird was singing(as Sibley describes) his alternate song. This is a first ever breeding season sighting of this species for this birder in the Breaks. Hopefully we will find further evidence of nesting. I'm leading a bird walk Thursday morning @ 8:00 from the Visitor's Center. Will keep you posted. DaveR/Breaks,VA
