Bluebird and Small Cavity Nester Conservation. The first brood per season March through April; subsequent broods and re-nests continue through August. Potential nest sites may be selected in fall with the male displaying at a nest site and used as winter roosts.

Nest site selection : The nest site is selected by the male. HOSP use natural cavities created by other birds, nestboxes, or various other sites. While they prefer to nest in cavities such as a nestbox, they will nest in protected locations such as rafters, gutters, roofs including clay tiles , ledges, eaves, soffits and attic vents, dryer vents, holes in wood siding, behind shake siding, dense vines on buildings, loading docks, roof supports, commercial signs, behind or above pipes and ductwork on buildings, wall voids, evergreens and shrubs.

May reuse nests of Bank, Barn or Cliff swallows, Eastern Phoebes, American Robins, and Northern Orioles, and even alongside osprey nests, often adding nesting material.

Nests are often in feet off the ground, which may afford additional predator protection. Nest construction : Both the male and female quickly construct the nest, which is a loose jumble of odds and ends, including coarse grass with seed heads , cloth, feathers, twigs and sometimes litter. Mid-summer nests sometimes contain bits of green vegetation mustards or mints. The nest is tall, and may have a tunnel like entrance particularly when built outside of a nestbox.

In a nestbox, it may have more of a cup shape, and may be built up to cover sides of box. These may be areas of wasteland or around garden feeding sites. Later, rural flocks may move on to grainfields to feed on the ripening grain, often joined by adult birds, once they have finished nesting. Flocks tend to break up through the autumn and birds return to their nesting colony sites. Martin Harper Blog.

House Sparrow nesting. House sparrows usually nest in loose colonies and since they don't defend a proper territory, nests can be as little as cm apart. How house sparrows nest Nests are often placed in holes and crevices within buildings and they will readily use nestboxes.

About house sparrow chicks The female lays two to five eggs at daily intervals and often starts to incubate part way through egg-laying. One solution to keeping them away from feeders is to use Finch Feeders filled with nyjer seed. House Sparrows won't eat the nyjer seed and it's available everywhere.

House Sparrows compete with many of our native bird species for nesting sites. If you want native species such as Wrens, Chickadees, and others to nest in your bird houses you'll have to control the House Sparrows.

Do this by removing nesting material quickly and and often. Once a pair has built a nest, they will defend their nesting territory fiercly against the less aggresive species. Are House Sparrows a Bad Bird? House Sparrows get a bad rap for the fact they harm other native species and eggs during nesting season.

But the truth is, their numbers have declined both in their native country and in the United States. In the birding world they are not considered to be causing populations declines in our native species. There are other native species that also destroy nest sites and prey on birds. The common House Wren for instance, is known to pierce eggs of cavity nesting birds. I've lost many Martin eggs due to the Wrens along with Bluebird eggs. The rise in numbers of Accipiter Hawks such as the Cooper's and Sharp-shinned in towns and cities will have an effect on some species, especially at feeders.

Yes, House Sparrows are non-natives and cause a small imbalance in nature. But they won't cause the planet to spin out of control. My personal conclusion, if you're hosting Bluebirds or Purple Martins do what you can to protect them from House Sparrows. If you like having them around, enjoy. They're not bad, they're just birds. Predators Preadators of these birds include hawks such as Coopers , Sharp-shinned, and Kestrels. Other birds are Owls and Shrikes.
