  The moment he showed himself in the open he was
discovered by a Crow whose excited cawing brought others
of his kind from every direction until within the next
few minutes a dozen or more assembled and mobbed the
Owl after their usual fashion.
  I wonder why the Crows do not mob the young Owls.
They must certainly be aware of their presence. The
rabbit skin still lay by their side but it looked much
smaller than it did yesterday & I think they have
downed part of it.
  A black-throated Green Warbler was singing on Ball's Hill
this morning and I heard one or more Chimney Swifts
twittering there late this afternoon. Faxon reports
the arrival of the Least Flycatcher & Towhee at
Arlington on April 30th.
  After tea this evening Faxon & I took a long
walk through the fields in the direction of Concord.
We heard a Bittern but no Snipe. A tremendous
din of Hyla voices last evening & to-night. It
fairly made ones [sic] ears ache to approach the
edges of the ponds & river meadows.
