Research was reported by Anat Barnea & Fernando Nottebohm from Nottebohm's
laboratory at Rockerfeller University Feild research Station, Millbrook,
NY.  Original report:  Barnea & Nottebohm (1994).  Seasonal recruitment of
hippocampal neurons in adult free-ranging black-capped chickadees.
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES, 91 (Nov.), 11217-11221.

This follows work by Nottebohm & Co. on the seasonal decay and
regeneration of neurons in male finches related to song production.
