Yes. I have just witnessed a sparrow kill another. And I came across this question while hunting for an answer myself as to how often this happens.

Yes, both bluebirds and sparrows are cavity nesters. This means they both use birdhouses to make nests in. Sparrows are very fierce and often when fighting with bluebirds they kill its babies or break their eggs.
When competing for nesting cavities house sparrows often attack other birds. They attack bluebirds by pecking at their scalp. They often break eggs or kill baby birds.
