  The two Orioles met with to-day in a larger mixed flock                                
among oak woods on the Estabrook road a mile or more
from any farm or clearing are the only ones which I have
seen since th 24th when a single bird was abserved among
button bushes along the river near Clamshell Hill.  They
were abundant in the elms and orchards near the
Buttericks' up to the 18th after which they wholly
disappeared from the farms in that vicinity. It is singular
what becomes of the old males at this season. I have
not seen one since the 7th.

  Chipping Sparrows are still singing freely and                                             
just now (10 P.M.) I heard one give the full song      
in the trees outside my window the night being still       
and clear.

  Swallows were abundant in small flocks about the                                         
river and the meadows up to 23rd since when I
have seen only a few scattered birds. This morning
I heard a Barn Swallow give the full twitting song
and a sloitary bird of this species was flying
over Bateman's Pond at noon. A friend who came
from Marblehead on the 28th told me that Swallows
had been swarming there for several days. Our birds
then have probably nearly all departed for the east.

  The Martins however, have not left Concord yet .                                              
Indeed they have been exceptionally numerous during
the past week .  Most of them appear to be young but I
heard the song twice to-day. The broods of young perch
usually in leafy tree tops. Both young & old feed chiefly over oak
woods & visit the river & meadows much less often than do the Swallows
