Due to the cat's diligence, I rarely see birds on my feeder. They flit around and land high up the trees, but the cat lifts her head from her napping position and meows a warning at them. Every time. She's a lazy, but very effective guard. And I can't convince her that its not her job.
I suspected the birds snuck in feedings when Nala was off hunting mice. (Which she has started regularly leaving me as gifts. Another job I can't convince her is unnecessary.) However, she sticks pretty close to me when I'm in the yard, so I never got to see any birds on the feeders. Even the mocking birds just sit in the palm tree and think about it, but decide they aren't brave enough.
Sunday we were in the car about to leave, when we saw this cardinal land in the Crape Myrtle and look around. He then flew to the grapefruit tree and checked out the other side. After one last look from the palm tree, he settled down on the feeder for some lunch. I was delighted. And it also confirmed that they have learned to look for the cat before landing.
I don't think that she could reach them on the feeder, but they are clearly unconvinced its a risk they should take. So, I'll be dragging out the ladder this weekend and hanging the feeder higher. And then I'll curse that decision every time I have to get the step stool out to fill it.
