google is already on it when asking about "The Great Pigeon Census of 1887"

using 1886 or 1888 makes Google correctly identify that no such sensus exist.

asking about 1887 specifically makes Google refer to some supposed great effort to track passenger pigeon population mids of the species decline.

By Featherton, no less.

I made the same thing months ago, so you don't need to wait:
