Bird houses should be easily accessible to prying human eyes. Not so that you can spy on and disrupt the nesting behaviour of your wild birds, but so you can see how your birds are doing and, when the time comes, easily clean out the house.

Part of being a responsible bird house landlord is your willingness to look after your wild tenants. If you monitor your bird houses every week and evict unwanted creatures such as house sparrows, starlings, rodents, snakes, and insects, you’ll have much more success in the long run.

For your own safety, please be careful when you inspect those wild bird houses. You may find something other than a bird inside! Don’t be surprised to see squirrels, a mouse, a snake, or a nest of bees or wasps. As for insects, inspect the house for fleas, mites, larvae, and lice on the bottom panel.

If you find insects or parasites try to temper your first reaction to grab the nearest can of insect spray. If you use insect spray use only insecticides known to be safe around birds. An easy check is the label on the can; 1% rotenone powder or pyrethrin spray are known to be safe for wild birds. If wasps persist over time it will help to coat the inside top of the box with bar soap.

Here’s how to check your nesting boxes or bird houses:

Watch the nest for awhile. If you don’t see or hear any birds, go over and tap on the box. If you hear bird sounds, open the top and take a quick peek inside. If everything’s okay, close the box. If you see problems (parasites or predators), remove them and close the box.

This is one time when a bird house with easy access comes in handy! Most bird houses can be opened from the top, the side, the front, or the bottom. Boxes that open from the top and the front provide the easiest access. Opening the box from the top is less likely to disturb nesting birds. On the other hand, it’s absolutely impossible to open a box from the bottom without the nest falling out. Side and front opening boxes are convenient for cleaning and monitoring but they have one major drawback: the nestlings may jump out.

If this happens, don’t panic. Just pick them up and put them back in the nest. Don’t worry that the adults will reject the nestlings if you handle them. That’s an urban legend, old wive’s tale or myth. Most birds have a terrible sense of smell.

If you clean out your nesting box after each brood has fledged, several pairs may use the nest throughout the summer. Many cavity nesting birds will not nest again in a box full of old nesting however so a good cleaning says “We’re open for business!”

In the fall, after you’ve cleaned out your houses for the last time, you can put them in storage or leave them out. Gourds and pottery nests will last longer if you take them in for the winter. You can leave your purple martin houses up, but be sure to plug the entrance holes to discourage starlings and house sparrows habitating the bird house before the martins return.

Leaving your wood and concrete houses out provides shelter for birds during the harsh months as well as flying squirrels.
