Yesterday, I shared a blog post titled Eastern Bluebird Fledgling Feeding Continues in My Yard and mentioned how this season seemed calmer. I wrote, “These new shots show a quieter moment compared to the hustle of early spring. No nest building. No competing males. Just steady care as she feeds one persistent fledgling after another. It’s a calmer season now, but her work continues.” But that calm didn’t last.
On May 20, in my yard here in Arkansas, I witnessed a violent moment between two familiar backyard species. A juvenile Eastern Bluebird wandered too close to a nesting American Robin, and the result was immediate. The Robin attacked, dragging the fledgling to the ground. One of my photos clearly shows feathers in the Robin’s beak.
Robins Aren’t Always Gentle
I used to think of American Robins as mild-mannered songbirds. Over the years, though, my perspective has changed. When it comes to defending their territory during nesting season, these birds are fiercely protective. They won’t hesitate to chase off intruders, even if it means attacking smaller, more vulnerable birds like bluebird fledglings.
A Mother’s Defense Saves Her Young
What made this encounter even more intense was what happened next. The mother Eastern Bluebird was nearby and didn’t hesitate. She began diving at the Robin repeatedly, striking hard enough to distract it. Her persistence paid off. The Robin finally released her young, giving the fledgling just enough time to escape. It was a dramatic and emotional moment, and a powerful display of parental instinct in action.
A Harsh Reminder of Nature’s Rules
Spring brings a flurry of nesting, feeding, and fledging activity. It’s easy to get caught up in the charm of parent birds feeding their young. But moments like this serve as a stark reminder that nature has its own set of rules, and they’re not always gentle. Every bird is fighting to give its young the best chance at survival, and sometimes that comes at the expense of others.
