  In the oak woods lying between Birch Island and
Green Field I found the nest of a Solitary Vireo this
afternoon. It held three fresh eggs prettily marked with five
spots of reddish brown. I was attracted to them by the
anxious scolding notes of the parent birds who were mobbing
a Jay. They darted about his head like angry bees striking
at from above with their bills & evidently annoying him a
good deal although he kept on hopping from twig to twig
peering under every (?) as if he thought it might conceal a birds'
nest. Perhaps, after all, he was merely looking for brown tails (for
I saw him tear one of their nests open & scatter the contents
with a quick shake of the head) but the vireos were evidently
convinced that he was seeking their treasures. After he had
flown away they continued in the tops of some tall oaks
where they had been with the Jay. Of course I knew 
their nest must be lower down & after waiting for
