May 50. On examining the tree from the opposite^next morning I found 
that it had at j\ist this place a round, neat-looking hole 
quite large enough for a Whistler to enter and without doubt 
containing a nest and eggs. 
It is remarkable, however, that four birds should have 
circled together so many times about this tree, but at times 
two of them would go off leaving the other two to continue 
i 
their gyrations. They were all silent most of the time but 
once or twice I heard the loud continuous call noted here last 
j■ year.

j May 31. Watrous found a Whistler's nest this morning in a short 
maple stub where we broke open a nest containing eggs last 
year (I have photographs of the stub taken last spring). It 
had eleven eggs none of which were covered. This nest is 
| 
within 30 yards of the one in the tall stub about which,the € 
four Whistlers were circling yesterday. I thought then that 
one bird which separated from the rest and swept 13>w down 
through the stubs might have gone to this nest.
