Red tail hawks and bountiful blueberries

Every year at this time I have a running dispute with the robins, cardinals, waxwings, and chicadees. Their point is simple enough. They are fruit eaters, and August is blueberry month in Michigan. The newspapers and restaurant advertisements back them up. I on the other hand feel that I am the landowner, I tend the bushes and keep them healthy and therefore I should be able to pick what I want. I have the full body of Michigan property law behind me.
Most years the dispute comes down to name calling. I have had tiny chicadees, no bigger than a canary, sit on a branch two feet away and scream at me. Robins, the gentle harbingers of spring, dive bomb me, and cardinals barely out of reach dive in and out of the bushes gobbling what they can as I harvest what the feathered marauders leave me.
Most years I get some berries,but the birds get the lion's share. All this changed this year thanks to a couple comical allies. Last spring, a mother red tailed hawk decided to nest in the woods behind my property. I only became aware of the growing family as the ground squirrels, field mice, and bunnies disappered from my yard. In July, a pair of baby hawks fledged and took up residence atop my garden gate. From there, they make the other residents of my yard nervous, though I find them comical. I saw one overshoot a squirrel and send them both tumbling. The attack made the squirrel so angry he chased after the hawk chattering forcing the hawk to retreat. Another time, I watched one spend ten minutes on my sky light trying to get to my cat basking on the carpet below. I've even seen them overshoot a branch and end up dangling upside down by one foot.
The songbirds don't care. To them a hawk is a hawk, and they will dine elsewhere thank you very much. So for this year I reap an unexpected bounty of berries thanks to the vigilence of two feathered buffoons who sit above me in the trees intimidating the songbirds with their terrible squeak toy cry.
A part of me is tempted to draw a universal principle from all this, but I will take the high road instead. I will quietly munch my fresh blueberries atop my Cheerios, and wish my accidental allies good luck with the coming winter.
I sure hope they come back next year.
