Birdwatching Dot Com Newsletter Early Spring Birding
March 2007

Hi Bird Watcher!


It's spring officially. At Birdwatching Dot Com, in Iowa, crocuses are pushing up. Woodcocks call peent each evening at dusk. Male red-winged blackbirds are starting to display their red epaulettes. The females, who migrate later than the males, will be back any day now.

  • Calculus of Spring
    American Robin

    Spring begins at a mathematical moment in March. But we humans have our own, more personal, means of calculating the beginning of spring.

    For me, spring begins with the first song of an American robin. Before he sings, certain conditions must be met, and those conditions spell spring.

    Dear Diane...

    The northern mockingbird suddenly became the king of the yard. I hear him during the night and early morning. He wakes me up. Is there anyway I can discourage him from my backyard?

    Male mockingbirds sing at night if they are bachelors. It's the way they try to attract a mate. After they find a partner, they stop the nocturnal serenades.

    So the night singing probably won't go on for long. Think of it as a love song.

    How Binoculars Work

    Ever wonder what's going on inside your binocular?

    Essentially, a binocular is simply a pair of telescopes mounted side by side, one for each eye.

    Inviting Bluebirds

    Here's a secret. Bluebirds are crazy about mealworms. Last spring, our eastern bluebirds peeked into the birdhouse, but they didn't seem to be moving in.

    The next day, Federal Express delivered 1000 mealworms to my door. The weather was cold and drizzly. I hadn't seen any bluebirds all day. I picked a dozen mealworms out of the box.

    I put them on top of the birdhouse and retreated to my kitchen. An hour later a female bluebird was standing on the birdhouse roof.
