Additions to Boston Hollow 2010 list

I have spotted a few more new birds for the BH area in the last week or 2.  The total is now 88.  Recent additions include Belted Kingfisher, Red-breasted Nuthatch,  Mallard, Brown Creeper, Sharp-shinned Hawk, Black-billed Cuckoo, Least Flycatcher.  There were 2 Juvie RB Nuthatches, fluffy and blotchy - obviously recently fledged.  I Still have not found an adult, though I have been looking, but obviously, they are there.
UPDATE:  I first used my sound recorder on June 21st, and made a large number of recordings that day, trying to get the hang of using the thing.  I discarded alot of the bad ones, but conditions were excellent that day, there was almost no wind and the birds were still singing quite lustily in places, so I still had quite a few decent tracks.  I have been trying to catch up with editing my recordings now that the birds are not  giving me as much new material, and when I went back to that day I found one recording with the faint but clear sound in the background of a Red-breasted Nuthatch calling.  At the time, my ears were so overloaded with sound that I hadn't noticed it!  It was in the same area, so it seems likely that it was the dad of the 2 juvies I just spotted!
