Heavy flight of Black polls during stormy night.
Peabody birds arrive

  A fairly heavy north east rain storm began soon after dark last
evening and continued well through the night but today was clear
and uncomfortably warm & humid with light southerly winds.
  Birds of most kinds were scarce yesterday but the whole region
lying between Ball's Hill and the Farm was alive with Black-polls
to-day. They were so evenly and generally distributed that I had
them almost constantly in sight wherever I went. In all I must
have seen fully 100 of them. Thus for the second time this month
an exceptionally heavy flight of these Warblers has appeared here
on a morning following a night of north-east wind and
heavy rain. I saw also (at the Farm) eight White-throated
Sparrows, noted for the first time this autumn.
Many of the warblers left almost as soon as it was dark
this evening. At least I heard them chirping at frequent
intervals high in air over the river about 7 P.M.
