If I was to put up a box like that in my yard it would be
taken over by squirrels within days and no bird would
have a chance against them. I put up a dozen hexagonal
and octagonal boxes of my own design -- cedar wood and
copper-covered roofs. Almost immediately I found the
squirrels remodeling them to make the openings large
enough to enter. I tried covering the fronts with
polycarbonate shields with appropriate sized holes over
the originals figuring that even squirrel incisors
couldn't chew bulletproof plastic but in a couple of
cases they just chewed their way in from the side. For
now I've given up, at least until I can figure a way to
weld up bird boxes from steel plate.

You could look for a large can of something at the market and empty the
contents through a hole made with a can opener. Storage tins, tea or coffee
pots, metal containers at flea markets. Try Google
