New Developments in the Case Man vs. Squirrel

I thought the squirrel guard put an end to it, but I was wrong. Last weekend, I learned that the squirrels had chewed off part of the funnel's rim, and one of the furry creatures was basking in the sun on the perch of the birdfeeder, according to a first-hand, eye-witness account. My dad resolved to not give up but to "go to the mattresses." He put a shield of some sort over portions of the funnel. (Note that this action is perfectly legal as it was done in self-defense.) I cannot recall the material of this shield, but for now, his efforts have succeeded. The suspect, however, remains unapprehended. This was [supposedly] derived from an old police report:

WANTED

Current alias: Squirrely "The Unstoppable" Varment
Age: Unknown
Height: 7"
Weight: 1.5 lbs.
Description: "Squirrels are generally clever and persistent animals. In residential neighborhoods they are notorious for eating out of bird feeders, digging in potted plants either to bury or recover seeds, and for setting up house in sheltered areas including attics. While many companies sell bird feeders which are supposedly 'squirrel-proof,' very few of them really are" (Wikipedia).
