I got to wondering this morning if it is time to ensure they're ready for prospective tenants. I just now looked out the window and exclaimed "Uh oh!" as I saw two bluebirds out there, one standing on one of the boxes. I guess it's time.The end a February is the traditional time to check and clean bluebird nesting boxes for prospective tenants.whisky rocks Roosting boxes in which they spend the winter, should be checked, cleaned and taken down at the time of years as well.
