Peek in a English Sparrow's nest box:
There were many clues this is an English Sparrow's nest.
English Sparrows (Passer domesticus) or House Sparrows as they are commonly called are a non-native bird. They were released in America around 1850. They were released in hopes of them eating bugs. Ironically, they are primarily seed eaters.
Later it was discovered that they aggressively compete with native, cavity-nesting birds like bluebirds. Male sparrows have been observed destroying eggs, killing nestlings, and sometimes killing incubating females in an effort to take over an occupied nest box. This competition for nesting sites has contributed to the decline of the bluebird.
Many bluebirders do not allow English Sparrows to successfully nest in their nest boxes.
English sparrows are an unwelcome, nonnative pest bird.
