A "crazy" Robin.

  A "crazy" Robin has been at work recently in the
open shed at the Ritchie place where, on a long, low
beam that supports the roof, I found to-day no
less than eight nests, each occupying the space between
two rafters that rest on the beam. The central nest
of this interesting collection was completely finished &
neatly lined but empty. In both directions from it
the other nests become less and less complete the outermost
ones being really loose piles of dry grass & reed stalks.
Quite evidently this was still another case of a stupid
bird (Faxon calls such "crazy") who could not remember
from trip to trip where she had left her last load
of building material since the spaces between the
rafters were all exactly alike or, at least,
essentially so. A similar instance came under my
observation years ago at Warren, N.H. [Warren, New Hampshire], & others have been
reported of course.
