NOTES
1. The pattern of song remains fairly constant. The Redstart is
the first bird heard—Chaffinches, Tits, etc., do not start until
the sun is well up.
2. In 1963 and 1964 no Wrens were heard singing.
3. A Nightjar was heard in 1964, this bird has not been heard in
this area for a number of years.
GRAPHICAL PRESENTATION
The graph (Fig. 1) shows where the maximum song lies. The
method used is to divide a period of about 1 hour into 5-minute
intervals and every bird singing in each interval is noted. These
results show that the bulk of the song is made up of Song Thrush,
Blackbird, Robin and Cuckoo. With this increase of song it be-
comes difficult to hear the Redstart.
