April.

  Concerning conditions of weather, bird flights etc. at Concord during the 
earlier part of April I have no definite knowledge because of absence
at Washington. During the latter half of the month there was 
much chilly and not a little snowy weather with an occasional
warm day. As late as the 24th [April 24, 1914] the ground was hard frozen
on the surface at sunrise. Because of such conditions the
advance of spring during this period was slow & halting and
vegetation remained unusually backward up to the close of the
month. Nor was there any marked in-rush of migrant birds although
many species became represented by a few pioneer individuals on, or not
long after, their average dates of arrival. Those that had come earlier
on their way further north lingered uncommonly late. Thus we
had Juncos in considerable numbers through the month and one
or two Fox Sparrows stayed on up to May 2 [May 2, 1914]. The flights of 
both species were lighter than usual this year. Garden Toads
began their musical trilling on the 19th [April 19, 1914].
