Concord. - At Ball's Hill I saw nothing of interest
save a Red Crossbill flying about among the pines
above my house. Taking a walk behind the hill
I heard Wood Frogs in two different pools and
saw many of them swimming about. Through my
glass I could see that they were much greener
than they are in autumn. They were shy as
usual. One of the pools had the bottom covered
with ice.
  All day long the rolling croaking of Leopard Frogs
was incessant on the river meadows in every
direction. There must have been hundreds croaking
at once. Late in the afternoon I heard the
greatest number. The sound is certainly most
like the drumming of a distant Woodpecker.
Towards evening the Hylas were in full cry in
every meadow and swamp. Truly it was a great
day for the Frogs but I heard no Toads.
It was also a great day for Turtles. Every floating
log and board & many of the [?] trees were
clustered all over with Painted Tortoises. I also
saw a great many fish leaping & swishing & paddled
through a school of what I took to be Suckers.
Minnows were darting about in the shallows.
  As I paddled up river a little before sunset I
saw two Yellow Palm Warblers in the maples below
Hunt's Pond and a flock of about 40 Tree Swallows
flying over the meadows. Red-wings literally swarmed.
There were a few blossoms of the red maple out last
evening and to day both red & white maples are in
full bloom. I saw fully developed hazel catkins yesterday.
