Concord, Mass.
1900
April 17   
Ball's Hill
  Cloudy, calm, mild, with continuous but light and 
fine rain beginning about 9 A.M. Ther. 40 degrees
  At daybreak Robins, Song Sparrows, Redwings, a Phoebe
a Chickadee, and a Flicker were singing. Later I heard a
Pine Warbler and saw four Juncos feeding in the path near 
the cabin. Several Chickadees and at least two Downy Woodpeckers
came at intervals through the day to the suet which is kept
hanging in the black oak in front of our door.
Birds singing at day break
  After breakfast Purdie & I started on a walk. We
found the woods, fields and meadows brown, and
dreary looking under the leaden sky. The Arbutus buds were
swelled & pinkish but none of them had opened. Birds
were rather numerous. We heard Robins, Song Sparrows, Flickers,
and Red-wings frequently and Bluebirds once or twice.  A
Grass Finch sang over in Bensen's pasture. A Ruby-crowned 
Kinglet was heard chattering near the bars and another 
was singing on Pine Hill where we also found a Canada 
Nuthatch. Pine Warblers were heard about everywhere.  
We started three Partridges and a fourth was drumming
steadily on the log at the north end of Davis's swamp.
Vegetation
Birds.
  Will Bartlett who called yesterday afternoon, saw eight
Tree Swallows on his way down here. They were first seen
this season, he told me, by Fred Hm on the 15th.
Bartlett also said that Concord has been simply "flooded" 
with White-winged Crossbills the whole of the past winter.
Tree Swallows
arrive.
  Purdie & I saw no snow in the woods this morning 
but we found a great hill of thick ice extending the 
whole length of Pine Hill in the swamp at its northern
base. The river reached an unprecedented height during the 
February floods and this ice injured the shrubbery in and 
Winter rise of
