  I spent some time this afternoon thinning out the
trees close about the pine near the wood shed
where the Blue Jay is nesting. One of the birds
was on the nest sitting very deep within it, her
bill pointing almost straight upward. As I 
was chopping at an oak within 20 ft. of the
pine the other Jay (the male, I supposed) came
to the nest with something in his bill which
he gave to his sitting mate. She stood up in
the nest to receive it at the same time
quivering her wings & uttering a continuous low
chirping precisely like that of a young bird.

  The Phoebes at the farm began building
four or five days ago under the eaves of the
barn 15 or 18 feet above the ground. Their nest
appeared to be completed to-day & one of the
birds was sitting in it but then flew out & 
back every few minutes.

  The Lincoln's Finch which appeared yesterday
spent the whole of to-day in the thicket in front 
of the cabin in company with several Swamp
Sparrows & White-throats. He chased the former 
away from the millet feed but the latter chased
him. By afternoon he had become so tame
& trustful as to emerge from the bushes & feed
in the open path where Gilbert & I were standing
within ten feet of the feed bed. We came very
near getting a photograph of him while thus engaged.
He was singing the Junco song in the forenoon.
