European Starlings are invasive cavity-nesters that eat almost anything — corn, oat groats, insects, and suet are all consumed readily. They're gregarious and can overwhelm feeders in large flocks. While they provide some insect control, they aggressively compete with native species for food and nest cavities. Managing starling access is a key consideration for backyard birders.

Starlings will visit almost any feeder, which makes managing them a challenge. Caged suet feeders that only admit small birds are the most effective defence. Avoid offering suet in open trays when starlings are active. For seed, use tube feeders with short perches that starlings find awkward. Switching to safflower-based blends can also help, as starlings tend to ignore safflower.

As an invasive species, creating starling habitat isn't generally recommended. Instead, focus on limiting their impact: seal cavity entrances on your home and outbuildings (they're aggressive cavity nesters that displace native bluebirds, chickadees, and woodpeckers), use starling-proof suet cages, and avoid offering large quantities of food on open platforms that attract starling flocks. Prioritizing native cavity nesters through properly designed nest boxes with appropriate entrance hole sizes is a better ecological investment.

Start with the right food, keep feeding consistent, and create a space birds feel safe returning to again and again.

Small changes in food, feeder choice, and consistency can make a big difference.
