Chickadees 
building 
Phoebes were unusually numerous along the river 
and at Ball’s Hill alone I saw no less than three. Flickers 
have also arrived in some numbers since yesterday for I 
heard five different birds "shouting". 
In the swamp behind Ball’s Hill a pair of Chicka¬ 
dees were at work on their nest in a birch stump. The hole 
had already been dug deep enough for the working bird 
to be out of sight. 
About noon I heard Wild Geese and presently saw 
a large flock flying very high. As nearly as I could count 
them there werw about 45. 
An Osprey was flying about over the maadows 
near Davis’s Hill and I saw either the same or another 
bird higher up the river. 
I sailed home early in the afternoon. On the 
way heard two Field Sparrows singing and also a number of 
Tree Sparrows the latter all in one place — a flock of a 
dozen or more. Heard Crossbills in no less than four 
places to-day. One bird sang a few notes feebly. 
At 6 P.M. walked to the D a msdale via Derby’s lane. 
Robins in full summer numbers for first time this spring 
and singing fairly freely and well. Three Grass Finches 
singing in the pastures in the twilight. The swamps 
ringing with Hyla voices. Started a Junco from a. little
