Actually, I was interested to note that Griscom himself used the term
himself in that writing, which was dated 1955.

"We must now turn to the figure of Charles J. Maynard, a veteran but highly
controversial figure in New England ornithology, who lived in Ipswich,
collecting from 1868 to 1875, and who rowed himself across to Plum Island at
least as early as 1872. Because his original business of taxidermy and
professional collecting was halted by protection and the decline of
interest, and because his private publishing enterprises never made any
money, he cashed in, shrewdly enough, on the rising popular interest in
birds and started a series of bird walks for a fee in 1893. These walks were
a tremendous success, and many people now well-known birders in New England
and members of the Nuttall and other clubs owe their original training and
inspiration to Mr. Maynard. "

But I think Mike's point is fair, in that the term has become more
widespread and applied with a broader brush in recent decades.
