(No 4)          
  All three of the nests of Dendroica caerulescens which
I examined to-day on Great Island were in beds of
Yew a few rods from the Lake shore. One (3045/4) was in short,
rather scanty Yew about 8 miles above the ground, another (3046/4)
in dense, taller Yew about a foot above the ground, the
third, (3047/4), on excessively rank Yew waist high but the nest
not over 15 inches above the ground. Two nests were
near large, prostrate logs. All these birds were sitting.
Two flew from the nest at a distance of eight or ten
yards in advance of us & one of these would next return
to her eggs while my camera was in position about
6 ft. away although I left it there for over an hour.

  The third bird sat more closely than any [female] of
this species that I have hitherto seen. Watrous
struck the Yew within six inches of him with his
stick without starting her. Later I set up my
camera first about six feet away, then four feet,
& finally within two & one half feet using the
focsuing cloth each time & taking six picture in all[.]
When the tripod leg shook the branch which
supported the nest the bird would raise her head
and crane her neck out over the edge of the nest
to get a better view of me. At all other times 
she sat very still merely winking at short regular
intervals. My photographs show her position in
the nest well. When I had finished my work I
packed up my camera & photos & left the bird still
sitting on her eggs. Watrous took both nest & eggs
the next morning at about 8 o'clock when the 
bird was about.
