|Tree Swallows, Charles River Peninsula, Needham, MA|
|Four of the nine chicks|
|Box seven. Scene of yet another tragedy.|
|Murderous House Sparrow|
By the way, Bluebirds!: Special Ridge Hill Unit is somehow still going. Only five of seven boxes still on line. (One lost its lid. One was knocked down.) The good? An actual tree swallow nest (no eggs). The bad? Full house sparrow nest, with 4 eggs. Nest box management happened.
