Field notes on this piece
Nursery colonies of big brown bats need a range of temperatures: mothers and pups shift between warmer and cooler chambers as the sun moves. Three chambers at 3/4 to 1 inch, plus a vented lower section, give them that choice.
Mount back-to-back on a pole with a second house, or on the sunny side of a barn or garage. This is our recommendation for rural properties, farms and lakeside lots.
What sets it apart
