Concord, Mass.
1898.
April 9
  Clear the early morning cool, the middle of the
day uncomfortably warm (there. about 68 [degrees]), altogether
the most springlike day thus far.
  Spent the forenoon in the woods, the afternoon
near the cabin. Pine Warblers arrived here this
morning when I heard two males singing, one on
Ball's Hill, the other on Davis's Hill. 
  For the first time this spring we have had
all day a full chorus of Frog[s], Hylas, Leopard
Frogs & Wood Frogs. The Hylas are still in full
cry as I write this (9 P.M.). The Wood Frogs 
began in the little pond directly behind Hall's Hill
this morning & they were still croaking, although
in reduced numbers, in some of the [?] places. 
  I see Red-shouldered Hawks every few days
but the pair which I thought would nest
on Holden's Hill departed ten days or more ago
& the birds here now are silent & have no fixed
haunts.
  All the Juncos apparently left this locality
night before last but there were two Fox Sparrows
near the cabin both yesterday & to-day. 
  A Blue Jay was screaming on Ball's Hill this
morning the first I have actually noted on this
hill although I saw one or two in March on
Dakins' Hill.
