what size holes for starling

When it comes to starlings, the size of their birdhouse holes matters. It must be designed in a way that entices them to live there, and keep them safe. Here, we’ll look at the ideal size for starling birdhouses.

Starlings are cavity nesters. That means they prefer nesting in holes, crevices, or cavities. The entrance hole should be 1.5 inches in diameter. This prevents larger birds like woodpeckers from taking over. If it’s too small, starlings can’t enter. Too big, and it’s open season for unwelcome guests.

Research into starling behaviors and habitats led to this specific requirement. The 1.5-inch diameter hole effectively attracts and accommodates these birds. It provides a great nesting environment for starlings.

Understanding the starling species

Starlings possess some incredible features! They have the ability to mimic sounds like human speech and car alarms, and they can form huge flocks known as murmurations. Plus, these avian architects build amazing nests out of twigs and leaves.

Not just that, but starlings are also incredibly social and possess impressive problem-solving skills. They can survive in many different regions across the globe due to their adaptive traits.
