The cats are, that is.
The birds have finally found the feeder that I put in the yard back in November (way to be observant, guys!), and they're hitting it hard. I put it in the front yard this year, partly to give the birds some cover in the bushes nearby, and partly because this way I can watch them while sitting on the couch blogging (ahem).
I also put the feeder there because it's right near the window where the cats normally hang out anyway - I figured it would be like Kitty TV. When the first birds appeared, I called Zach over to the arm of the couch and pointed out the window. Zach normally isn't Mr. Observant, either, and I don't know if I've ever actually gotten him to look at something I was pointing to ... until today. Dude started barking his head off (yes, cats can bark) at the birds, and I thought he was going to launch himself through the window (which would have been problematic, since it's got a Christmas tree in front of it). The initial flood of birds - maybe half a dozen female cardinals and a couple of house sparrows or house finches, plus a black-capped chickadee - went down eventually, and Zach regained his sanity.
Just now Bella finally noticed the birds, and SHE started barking at them, and she never barks at anything. She pretty much ignores the squirrels and chipmunks (which Zach happily stalks and yells at through the sliding door) and hardly ever meows unless there's something wrong (like her food bowl being less than half full). But she stood on the arm of the chair and yelled at those birds for a couple of minutes straight. She's quieted down now and trying to pretend that she's resting, but I'm not fooled. She's trying to figure out how to open the window so she can go get those suckers.
Good luck growing some opposable thumbs and bulking up enough to turn the crank on the windows, babe!
Now that I know the birds will actually come in this close to the house, I'll have to see if I can manage to get another kind of feeder out there. Just having hulled sunflower seeds won't do it for long, not if we want to have more than two or three kinds of birds around. I'm thinking of getting a feeder for nyjer seed to see if I can get a few more finches. And maybe if I'm feeling really kind I'll get one of those suet/peanut butter feeders for the squirrels in the back. At any rate, it looks like the Ohio Birds guide is out to stay, at least until we can recognize all of the usual suspects at the feeder.
