Feeling Squirrely

We have an abundance of squirrels in our backyard. I understand this isn't a rare condition, but it's a bit of an irritation on days when their numbers appear to be greater than the birds. We put the feeders up for the birds after all.
I watched a news (or was it a cooking show?) segment on BBC America a few months ago about London being overrun with non-native squirrel species. The reporter suggested that perhaps if the entire population ate one squirrel every week or month or ??, the problem would soon be solved - as well as fewer people going hungry. I assume if I'd stayed tuned to the channel, a segment on ways to prepare squirrel would have been forthcoming. Maybe I should've stayed glued to the couch. There might come a time when I need some survival tips. :>.
My daughter Lise and her hubby J (along with their Jack Russell terrier and cat) have been living with us since last summer. I believe their terrier, Nixon, sees the squirrel residents as a challenge. He sits by the sliding glass door watching their frantic activity. Is he planning how to capture one of those furry morsels? I don't know if that's what he daydreams about, but that IS what he did. I've never seen (and that squirrel evidently hadn't either) a dog move so fast. It took both Lise and I to prevent him from enjoying his swift kill and to dispose of the body. I think a leash will become imperative when letting Nixon out in the future.
