Shooting birds

I'm trying to find a reference for a quotation about bird collecting in the late 19th or early 20th century, a propos of some rare species spotted in England "Someone who ought to have known better let it get away"

Possibilities are

• Nelder, J.A. (1962). A statistical examination of the Hastings Rarities. British Birds, August 1962.
• Nicholson, E.M.; & Ferguson-Lees, I.J. (1962). The Hastings Rarities. British Birds (August 1962) 55(8): 281.
