  In the early afternoon, after the preceding pages were 
written, hordes of Water Thrushes appeared near the 
cabin. A few clung to the moist thickets by the river
side where they belonged by right but the greater
number rambled all over the hillside around &
behind the cabin while a few betook themselves 
to the tops of the leafless oaks where they tripped
nimbly among the branches feeding in company
with a number of Dendroicas. Several ascended
the stone steps in front of the cabin & peeped
into our open door curiously. They were nearly
all remarkably tame & free from that obvious
nervousness that usually distinguishes their kind.
They were continuously quarreling with one another
& I witnessed several encounters where two birds
would clinch and flutter together among
the dry oak leaves.

  At about 3 P.M. A Traill's Flycatcher appeared
in the oak in front of our door where it
sat for a minute or two calling pip and 
twice uttering a prolonged succession of slight
but rather unusual twittering notes given very
rapidly. This I have heard before but not 
often.
