Month by month in this state
Highlighted months are when house wrens are expected in Pennsylvania. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.
Getting ready before they arrive
The week before April is the time to act. This species doesn't use feeders much, but water and cover matter — a clean birdbath and undisturbed shrubs make a yard far more attractive to a newly arrived bird.
House wrens nest in cavities, so boxes need to be up and cleaned before arrival — a box mounted after they've claimed territories will usually sit empty until next year. House Wren nest box dimensions and mounting →
Once nesting begins around May, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
What house wrens eat while they're here
- Beetles, caterpillars and crickets
