A starling has been trying to build a nest in my bluebird house. I remove the nesting material and the bird brings more. Today a bluebird was checking out the house, so I removed more nesting material.
The starling went into the birdhouse and a bluebird pecked it right in the butt.
From past experience, this is not the season for a bluebird to build a nest so,I don’t know why it was defending the house.
I think that’s either a female house sparrow or a chipping sparrow and not a starling. I’m leaning toward chipping sparrow due to the striping on the back.
I don’t think it’s a starling based on the beak structure and the v shaped tail.
Blue Bird was just running off squatters or it’s house flipper trying to make a quick buck.
I learned something. Thanks. I use sparrow and starling interchangeably because they are both invasive.
They eat from my bluebird feeder but I don’t know any way to keep them out that will not keep the blue birds out.
We get a lot of them here. Not so much starlings, they tend to stay out in the fields. We mostly get house finishes, house sparrows, cardinals, mourning doves, Robins, and hummingbirds. Occasionally gold finches, Tufted titmouse, woodpeckers (red belly or Downy), Carolina wren, black capped Chickadee, and once a grackle.
Don’t have any birdhouse, just feeders right now.
I have a heck of a time with Squirrels, though. They’ve broken at least 2 of my window feeders… And it’s the only reason I didn’t jump on getting a Wyze feeder. It’ll just get broken by those cute, pesky tree rats.
