birds for example, seem also attracted by his song. In all
this the musical phrase:
is delivered frequently with full power, without losing its melodious
character. Clearly B has the magic touch; but why, when he attracts
all of these bird, doesn't he "do something about it"?
9:57. Still at it. Going out to see operations.
10:30. B was still on the same perch, but his song had changed,
the above phrase being absent. Echo of his voice could be returning

During this period loud thrasher song came from the north and the
south east also, distant birds. There was also soft song in the acacias
near the magpie cage while B was singing aloft. Bb came out from

him temporarily from his course by displaying worms, which he came and
