When you live in a climate where winter dominates much of the year, the first signs of spring are enough to get your blood flowing and optimism churning. In February, the Red-winged Blackbirds return and mark my favorite day of the year- when I first hear them singing. Like many things that are ‘common’ it may not be the most newsworthy event. The Sibley bird guide states, “common; our most widespread blackbird,” but to me their song is the best sound of the year as it marks the beginning of the snow melting, longer days, and warm sunshine on my face. The year is marked by the movement of animals and birds to and from the preserve. And there is no better way to watch the birds than to put up a birdhouse and give them a place to nest. Thanks to our wonderful volunteers last year, Pete Martin who built the houses, and Doug and Nan Little who put them up, this year the preserve is covered with great nesting boxes for swallows, wrens, kestrels, owls, and ducks.

How hard is it to build a birdhouse? Not that hard- four sides, a roof, and a base with a hole of some sort. At least that’s what I thought; in actuality, in order to get the ‘right bird’ to the ‘right box,’ it is important to be a little more detailed than that. For instance, you need the right size hole—having a hole too big will bring in the starlings or magpies. And you need to mount them at the right height. Put a kestrel box at 8 feet instead of 15 feet and you may end up with a Saw-whet Owl (maybe not such a bad thing). And maintenance is necessary too. Boxes must be cleaned annually. For nest-building birds, last year's nest materials must be removed as well as leftover food remnants and droppings. Nest materials left to accumulate put young birds closer to the box hole and make them easier prey for squirrels, raccoons, and other opportunistic predators.
Pete Martin, the visitor center host in September at the Silver Creek Preserve, took my suggestion to build a few birdhouses to the extreme last year. He researched, scrambled for the least expensive materials, and $300 and six months later, delivered over sixty birdhouses to the preserve.
This is important because many bird species have suffered from dramatic population declines due to loss of habitat and nesting structures (tree cavities in many cases). Loss of habitat is often a result of logging, industrial and residential development, cultivation of land for agriculture, and other influences. Providing suitable nest boxes can have a very positive impact on bird populations in rich settings like the Silver Creek Preserve.

Each species requires a different maintenance and mounting plan, but the birdhouses themselves are relatively simple to build. Click here for a nest box spec sheet. Don’t worry about making them beautiful- we found that the most simple and boring birdhouse, if designed and mounted correctly, attracted exactly the right birds.
It’s spring—and there are birds out there looking for a place to nest!
