The 2025 bluebird breeding season is here! Have you spotted any? Check your nest boxes regularly. ​Pale blue eggs indicate bluebirds, while other colors may belong to native songbirds or invasive house sparrows.  If you find house a house sparrow nest in your next box it should be removed right away, including any sparrow eggs that may be present.

​

Bluebirds may reuse their nests for multiple broods or move into vacated boxes later in the summer. Attract them by offering nesting habitats and treats like mealworms and suet. Happy birdwatching.
