Cambridge, Mass.
1902.
August
  The average temperature during this month has been 
almost if not quite as cool as it was through July
but we have had a few uncomfortably warm days. The
nights without exception have been cool. There has been
more bright, sunny weather than there was in July and
much less rainfall.
  I have spent practically the entire month in Cambridge
but I have visited Concord nearly every Sunday and
have devoted several days to taking photographs in
Belmont, Watertown and the Fresh Pond Swamps
while on the 28th I went to Ipswich for the day.
  The month has been memorable for the almost total
absence of any indications of bird migration. The only
species which I have noted which, without question, had
come from further north were the Water Thrush which 
appeared in the Garden on the 19th and the Night Hawk
of which a single representation was seen flying over our place
on the evening of the 21st and again the following evening. 
It is possible, however, that a Wilson's Thrush seen in the
Garden on the 20th and the Black & White Creeper observed
in the same locality on the 15th were also migrants from
more northern summer haunts.
  Hummingbirds have been infrequent visitors to the
Garden this summer and I have noted them there
only four times the present month. On the
27th I saw two together near Smith's Pond, hovering over
a bed of Impatiens.
  The Night Heron appear to have almost if not quite
deserted the Cambridge Region. At least I have heard
none this year but I saw a larger bird which I 
took to be a Night Heron flying over the Garden on the
evening of the 21st, as twilight was falling.
