CONCORD 
l^ame to Concord this morning and drove down to Ball’s Hill, 
reaching there about 11 A. M, In the late afternoon (l) 
heard in the woods behind the Hill a Cat-bird, a Black and 
White Creeper (singing feebly and brokenly) and a Redstart, 
Flocks of Bobolinks were passing every few minutes. Two 
Kingbirds, A flock of 13 Cedar Birds flying over the swamp^ 
After supper I paddled up to Beaver Dam Lagoon, It 
was calm and warm with a brilliant sunset, the sky flecked 
with rosy clouds. Red-wings were flying about in small 
parties and going to roost in the beds of pickerel weed. 
Something alarmed them finally, when 24 rose from different 
places and flew off westward, A flock of 14 Barn Swallows 
passed and repassed me many times. I heard them calling 
after it was too dark to see them. ^Neither Forbush nor I 
has thus far ascertained where they roost. They are less 
numerous now than they were a week or two ago. Two 
Sv/amp Sparrows were in full song and I heard a Maryland 
Yellow-throat give the flight song twice^A Bittern rose 
from the marsh in silence and flew off, flapping almost as 
rapidly as a Duck, Two Siruaj Rails were calling near me 
at intervals. One of these made a peeping sound, not 
uhlike a Hyla and then changed to a toe. toe . toe note 
which I mistook at first for the distant pumping of a 
Bittern, As twilight was passing into night, a Night Hawk 
skimmed close past me and a Whippoorwill gave five exhibi¬ 
tions of its song note on the West Bedford shore.
