Concord, Mass.
1908.
April 25 
  Cloudy with soft, moist S.W. wind.
  I noted for the first time this spring
Brown Thrasher. - a silent bird in a brush heap on Ritchie place.
Usnea Warbler. - a male singing in the Barrett run.
Black & White Creeper male singing on the Barrett run.
Arrivals
  There was evidently only a small fight from the south
despite the favourable conditions for migration.
  House Sparrows are swarming on the Ritchie place this
spring. They have taken possession of two of the bird houses
there. I have shot four females thus far but the birds
still continue to hang about the houses & to keep off
the Tree Swallows that try to go to them.
