How Do I Choose the Best Finch Birdhouse?

When attempting to choose the best finch birdhouse, there are some specific features to look for, in addition to tips that apply to birdhouses in general. Finches are relatively small birds, so it is important to choose a birdhouse that will allow them to enter and leave, but keep out predators and larger birds. This can be achieved by selecting a birdhouse with an entry hole that is no larger than 1.5 inches (about 3.8 cm) in diameter. The ideal size for a finch birdhouse is roughly 6 inches (about 15 cm) on each side to provide these birds with enough space to nest. General tips when selecting a birdhouse are to choose a unit with a removable roof, sufficient drain holes, and to avoid anything with dark exterior paint.

Finches are small birds that are well adapted to birdhouses. They are typically not very difficult to attract to a yard with the right type of food, but predators can be a concern if you decide to install a finch birdhouse. In order to provide the best possible birdhouse for finches, it is important to reduce the risk of predators while also selecting a unit that will not overheat, become damp inside, or rot too quickly.


The most important concern when choosing a finch birdhouse is to ensure that it will not be accessible to predators. One way to do this is to choose a unit with a properly sized entrance hole. Finches need entrance holes that are about 1.5 inches (3.8 cm) in diameter, and larger holes can allow predators in, as well as larger birds that may compete with the finches for food, and drive them away. If you choose a birdhouse with an entrance hole of 2 inches (5 cm) or larger, any finch that nests there will be in danger from house sparrows and other species of birds.

Finch birdhouses can also be made safe from predators in a few other ways. One is to choose a birdhouse that has a thick front wall, or to add extra material around the entrance hole. If you can choose a birdhouse with a deep entrance hole, predators will have a more difficult time reaching inside. If the entrance hole is angled upwards, that can also prevent a predator from reaching the nest inside. A birdhouse that can be mounted on a steel pole, instead of a tree or the side of a house, can also be much safer for these small birds.

There are also a number of general tips that can help you find the best finch birdhouse. One important feature is a roof that is removable or hinged, since that will allow you to clean out the old nesting materials each year. It is also a good idea to look for birdhouses that have sufficient vent and drain holes, and an adequate roof overhang can help prevent rain from getting inside. Woods that are naturally resistant to decay are typically better than wood that has been treated or painted, and dark exterior paints can cause excessive heat buildup inside.

Frequently Asked Questions

What size should a finch birdhouse be?

Finches prefer compact spaces, so a birdhouse with internal dimensions of roughly 4x4 inches and an entrance hole of about 1.5 to 2 inches in diameter is ideal. This size provides enough room for the birds to move comfortably without being so large that it attracts predators or competing species.

What is the best material for a finch birdhouse?

Natural, untreated wood like cedar or pine is best for finch birdhouses as it provides excellent insulation and breathability. Avoid treated woods and metals, which can overheat. According to the Cornell Lab of Ornithology, wooden birdhouses also mimic the finches' natural nesting preferences, making them more likely to take up residence.

Where is the optimal location to place a finch birdhouse?

Finch birdhouses should be placed in a quiet, sheltered area, away from predators and high traffic. Ideally, mount the birdhouse on a pole or tree at a height of 5 to 10 feet. Ensure it's facing away from prevailing winds and has some shade to prevent overheating during the day.

How many finch birdhouses should I put up?

Finches are social birds but can be territorial during breeding season. Space birdhouses at least 10 to 20 feet apart to reduce competition. If you have a large yard, you can put up multiple birdhouses to accommodate more finches, as they enjoy flocking together, especially in the winter months.

What features should I look for in a finch birdhouse for easy maintenance?

Look for a birdhouse with a removable or hinged roof or side panel, which makes cleaning easier. Proper maintenance is crucial to prevent the spread of diseases among bird populations. Cleaning the birdhouse between seasons removes old nests and parasites, ensuring a safe environment for the next occupants.

When is the best time to put up a finch birdhouse?

The best time to put up a finch birdhouse is before the breeding season starts, which is typically in early spring. This gives finches time to find and settle into their new homes. According to the National Audubon Society, putting birdhouses up by late winter can increase the chances of occupancy for the upcoming season.
