Birdhouse hole size chart help you to protect birds?

A birdhouse hole size chart is vital for protecting birds by matching the entrance hole to specific species. Smaller holes are designed for small birds like chickadees or wrens, keeping out larger birds and predators. The entrance hole height is crucial to ensure it’s high enough to protect the nest. However, it shouldn’t be too high, so young birds can safely leave the nest. Installation height is equally important, as some birds prefer nests near the ground, while others nest higher up. By considering entrance hole size, height, and installation height, you create a secure and suitable nesting environment for birds.

Why you should use Predator Guards

The importance of predator guards is straightforward yet crucial: security. For instance, bluebirds often reuse nest boxes. However, if a predator like an opossum raids a bluebird’s nest, the bird will likely seek a safer location, leaving your birdhouse unused. Here, you’ll find instructions on selecting the right predator guard for your bluebird house. Watch the video below to see how a woodpecker, without a predator guard, can quickly enlarge the birdhouse opening and prey on blue tit chicks.

 

 

 

 

If you need to resize the birdhouse entrance hole?

It’s not uncommon to come across many birdhouses that come with an already drilled hole. The only shortcoming of such holes is that they may not be of the required standard size for the birds you want to keep in your yard.

If you find out that the hole size is too small for your birds’ needs, you can always use a paddle or a spade drill to increase the size. The paddle will enlarge the hole uniformly.

As you increase the size of the hole, you may require a tiny piece of wood to help the drill bit with uniform movement. You may also use the piece of timber to smoothen any rough edges after drilling.

Sometimes you may need to enlarge the hole only by a small margin. You will need to use a more minor or around drill bit to resize the birdhouse hole size.

Further, you will need to be keen and ensure you increase the birdhouse entrance hole uniformly without interfering much with the initial shape.

To decrease a bird house hole size, however, you will need to fix a piece of wood at the entrance using nails or glue. However, you may also opt for a wooden resizer to reduce the gaping space.
