Field notes on this piece
Three-quarter-inch western red cedar keeps the interior cool in June and dry in March. There is deliberately no perch — bluebirds don’t need one, and it only helps house sparrows. Inside, saw kerfs below the hole give fledglings a ladder.
Mount on a smooth metal pole 4–6 feet high in open grass, facing a tree or fence line within 100 feet that young birds can fly to. Pair it with a pole baffle and you’ll often get two broods a season.
What sets it apart
- Matches standard bluebird-trail dimensions
- Ventilation gap under the roof
- No perch to tempt house sparrows
- Interior kerfs for fledglings
