Such lovely birds, magpies. I like their song better than any other bird's, so I'm always delighted to see them wandering around our garden. Yesterday, one seemed to be finding plenty to eat amongst the mulch around our baby zucchini plant, when it stopped for a moment, looked up, and saw another magpie doing the same.
Oh no! Fear not, the magpie looked at its grazing partner, then continued on with the more important business of searching for insects in the mulch.
But lots of home owners with generous expanses of windows facing gardens will know what I am talking about, and have a much bigger problem. At the wrong time of day, at the wrong time of year, those windows become mirrors which can send mating birds into lethal frenzies of competition as they try to see off the "intruder" (by flying straight into the window). Whack! Some will do it repeatedly, such is there competitive instinct, and many birds have died for their cause.
It's such a hard problem to prevent, and as most gardeners love to not only see birds in their gardens but actively try to attract winged visitors with nectar plants, birdbaths, etc, it's just a risk for us to be aware of, and to helpfully 'shoo' a bird away from self-harm when you can, but in the mating season, your garden is "territory" to be fought for, and tragedy is always on the cards.
