Contrary to what you might assume, the best time to put up a birdhouse is late winter since some birds start scouting for a suitable and safe den in the colder months.
Hunting for that perfect hideaway is part of birds’ mating rituals, and investigating potential nest sites is also one of the first things some newly coupled pairs do together.
There is, however, an exception to this late winter rule. Since nests can get destroyed or abandoned, putting up a few new birdhouses in late spring or early summer could help.
Timing also matters when considering the types of birds you want to see, because although most birds nest in the spring, different species do so at slightly different times.
