June 9
[June 9, 1910]

  Clear & warm. Cloudy in late P.M. with distant thunder.

Helmin. leucobronchialis [Helminthophila leucobronchialis] [male] [female] & nest  5 eggs - young.

  I went to Lexington this morning to see a nest of
Helminthophila leucobronchialis. Walter Faxon & his friend
Dr. Tyler found it on June 5 when the [female] was sitting on
5 eggs and when they saw, flitting about in the trees nearby,
singing and chasing one another, a [male] H. Leucobronchialis [Helminthophila leucobronchialis] and
a [male] H. chrysoptera [Helminthophila chrysoptera], both typical birds. The nest was not visited
on the 6th but on the 7th Faxon went to it & found the
[female] sitting. He did not disturb her. The next day (8th) he
went again & found her feeding five young apparently only
just hatched. On this last occasion he saw the [female] leuco. [Helminthophila leucobronchialis] near
the nest but the [male] chrysoptera [Helminthophila chrysoptera] was not there.
  When he, Purdie & I went to the place about 10.30 this
morning we found the nest undisturbed & no birds near it at first.
It was built well up above the ground on the side of a dry ditch
between a clump of meadow rue and one of Golden rod (S. rugosa.) [Solidago rugosa]
