Arrivals
  Quail have been whistling bob white near the house
for the past four or five days. One began this note
at daybreak this morning just after the first Robin
and before any other bird. I had no idea they were 
such early risers.
  Just after the Quail began to whistle this morning
I heard the song of the White-bellied Swallow for
the first time in many years. It was continued
at short intervals for several minutes ceasing before
it was broad daylight. I noted it on the spot
thus: - Sit, clear, sit, clear, sit, clear, clear, sit, clear,
clear, clear etc. it is a monotonous & unmusical
song but very interesting nonetheless.
Song of the White-bellied Swallow
  Birds of most kinds continue scarce. Of the
species that ordinarily arrive between May 1 and
12 by no means all have yet come and of those
noted only a very few have appeared numerously.
The only well marked flight thus far was that 
which reached us on the 14th. Before & after
that date only driblets have come from day
to day.
