Despite the effort of over a dozen pairs of house sparrows, all three of my nest boxes have clutches of native birds
Brown-headed nuthatch, black capped chickadee, and eastern bluebird all are either hatched or well into incubation.
The sparrows were extremely aggressive this year, tearing apart several nearly complete nests in a matter of hours before I spotted them and could get the trap door in place. Shoutout to Van Ert for making a very high quality trap door that doesn't raise the suspicion of the sparrows, it was usually only a matter of minutes before I heard the snap and went clear out the captured invasive.
