When the connecticut flushed a second time to the lone tree near the dirt 
piles I had a great view for 10-15 seconds.  I would add that its wings and 
undertail coverts were long giving it a short-tail appearance.  

Other birds to add from the ridge and maintanance yard:

tennessee warbler
northern parula (2)
magnolia warbler (2)
black-throated green (2)
black-and-white warbler

and someone else reported a chestnut-sided warbler and a yellow-billed 
cuckoo.
