Blackbird Deterrent Cap

The eyes
have it!

UPDATE FOR SPRING 2026: If you’re noticing dive-bombing birds right now, you’re not alone.

Where I live, there is a huge migration every spring and fall of red-winged blackbirds. Though pretty, they can be surprisingly aggressive when protecting their nesting territory—your entire yard can start to feel like a bit of a war zone. They’ll dive-bomb squirrels, dogs, and definitely people. And if they feel particularly threatened, they may even band together and swoop as a group. As a gardener, this creates a yearly challenge when trying to tend the lawn.

An interesting thing about red-winged blackbirds is that, as bold as they seem, they almost never approach face-on - they come from behind. My neighbors deal with the same issue each year and suggested I try their solution: wearing sunglasses on top of the head so the birds see them as a pair of eyes. I gave it a try, and it did seem to help… but it wasn’t very practical for someone as active as I am in the garden.

Sometimes creativity happens from necessity.

So this is when I said, “There has to be another way.” I knew that many bird deterrents use the color red, so I started with a few blank red baseball caps. I also wanted to add “eyes” that would face both forward and backward. With some fabric paint and a set of googly eyes, the Redwing Deterrent Cap came to life… and it works like a charm!

It's certainly no fashion statement, but the birds truly don't know what to make of the eyes.

This agressive behavior is tied to nesting season, when males become highly protective of their territory.
