wind. Ground frozen slightly early morn.
  Awakening at daybreak I opened
two of the chamber windows &

fuller than for two years past &
almost normally so. These birds seem
to have doubled in numbers since last
spring. Song Sparrows sang freely far
& near. Crows cawing loudly. At
least 5 cock Pheasants crowing in
different directions, one close after
another & then a brief interval of silence.

song & a Purple Finch singing brokenly.
