About Wren Hollow

Wren Hollow started the way most backyard habits do: one house wren, one cheap birdhouse with the wrong-sized hole, and a summer spent watching starlings evict him. The second house was built to the right dimensions. The wren raised two broods in it.

That’s still the whole idea. A feeder or house that matches how a species actually feeds or nests does more good than a pretty one that doesn’t. So everything we sell is checked against the guidance bird-trail monitors, bee researchers and bat conservation groups publish — entry-hole diameters, chamber widths, tube sizes, mounting heights — and then against the more practical question of whether you’ll actually be able to clean it.

What we carry, and what we don’t

We focus on seven things: hummingbird feeders, nesting boxes, squirrel-proofing, pollinator houses, seed feeders, suet feeders and bat houses. We don’t sell decorative houses with perches that help invasive sparrows, red-dyed nectar, or anything treated with chemicals that would end up inside a nest cavity.

When something we sell has real limits — butterfly houses, for one — we say so on the product page.

How we write

Our product notes use common and scientific names, mention the regions and months that matter, and give one practical placement tip. Ranges and dates are general for the contiguous US; your own yard is always the better guide.
