Not all birds nest in boxes. Birds like Chickadees, Wrens, Woodpeckers, the Tufted Titmouse, and Bluebirds are all cavity-nesting birds and will nest in bird houses. Robins, Song Sparrows, Goldfinches, and Cardinals, on the other hand, are among the tree nesters who build architecturally magnificent nests in the crotches of tree branches and shrubs.
With the disappearance of farms, the wooden post and rail fence went away as well, leaving the open field-friendly bluebirds scrambling for homes they would normally find in the decaying fence posts. Rural lands have turned to developments, and the old decrepit trees which housed birds and other wildlife in rotting stumps are now cut down quickly in favor of manicured lawns and vistas— their charm left for the woodpile.
As more “people” houses go up, more trees come down, impacting birds and their breeding access. It limits places for hole nesting birds and causes tree branch nesters to find other options-- like under your roof or in your hanging flower baskets.
In 1890, a wealthy drug manufacturer in the US thought he was doing Americans a favor by trying to import every bird mentioned by Shakespeare into New York City’s Central Park. This poetic fancy turned disastrous. It brought the invasive, yet melodic Starling to our shores. This aggressive bird is a true survivor—winning the fight for holes in trees over our native birds. Occasionally, they have been known to bring down planes when they swarm. Offering a selection of bird boxes for our winged friends really helps native birds get a fair shot. The size of the hole is important. Keeping the holes under 2 inches prevents invasive home wreckers like Starlings and House Sparrows from taking over.
If you have a dog, offer your nesting birds some extra nesting material. They love soft dog hair, straw, Easter basket filler, and even human hair. Imagine the kids seeing a wonderful heap of trash sticking out of your bird box that includes April’s Easter fixings, and even their own hair. Things that you throw away become treasures to birds that have an eye out for soft nest linings, and binding materials that help keep the nest together. A good way to offer this material is to stuff it in a hanging wire suet feeder so the birds can pull it out when they need it.
Working in the Sickles Market flower yards, I see marvelous things. Robins nest in pots under cart shelves, and Song Sparrows make small, tight little nests in the grass and yarrow plants on the outside tables every year. The Cowbirds are always on the move there as well. Since they don’t make nests, (making no time for parenthood, they historically followed herds of buffalo and cattle on the move for the insects off the animals backs) they find many unsuspecting Song Sparrow and Goldfinch nests to lay their white eggs in. The adoptive mother gladly and generously sits on the eggs and raises the abandoned young along with her own. It’s a habit as old as time, and a bit of ecological cooperation that we probably will never understand. They say it takes a village to raise a child, and birds definitely follow this adage.
When birds inhabit your garden and make it their nursery, you will gain more than you think. Thousands of troublesome insects will be devoured and you’ll be more than happy that a bit of your blueberry crop will go to a good cause. Songbirds in the garden are taking a plunge—from the UK to Hawaii to the US, birds are being decimated by stalking house cats, dangerous chemicals, and escaped snakes and other reptiles. Sharing a bit of your bounty with them can help bring them back to their former glory. And, if you’re lucky, you may even lure a long lost bluebird to an old fence post or birdhouse in your little paradise.
