fast. At low speed his gate is no longer graceful, but waddling.
As soon as he saw me he abandoned the chase, reversed his course and
came to me for worms. He then waddled off, reestablished contact with
a thrasher (the same one I suppose) and gradually crowded him far off
to the east outside the property. The fugitive was not Bb, who attended
strictly to his own affairs while this was going on, although he
was in the zone of action. At this time there were four thrashers
definitely located on the place and perhaps more. If B intends to
keep this territory free of others of his kind, he is destined to be
an extremely busy bird. So far, I do not think he has had any support
from Nova, at least none has been seen.
The territory over which he is known to range--there is no evidence
of its not being more extensive--is 500 or 600 yards long and of irregular
contour, depending largely on the disposition of the cover. At
the eastern end it is known to be at least 200 yards wide. At the western,
it is known to be at least that and probably much more, as cover
is very extensive. In the middle known range, which includes this
place, it seldom wider than about 75 yards, though occasionally he
strays outside that limit.
12:20 P.M. Shortly after Brownie and the other bird thrasher
went off to the east, full song was heard from that direction and B
and two other thrashers were located near the top of the dying cypress at Robinson's. The song could be heard easily about 300 yards
away. On approach near the tree, the three birds could be seen in
amicable relationship, and a medley of sounds issued continuously
from the group. There was no clue to the identity of the two other
birds. The thought occurs that this tree is in no man's land and all
have equal rights there.
At 12:20 it occurred to me to look in the dormitory tree to see
if B might not have taken up his retreat there in order to rest after
the morning's excitement, and, sure enough, he on his night roost
