I have a tunnel opening to my bluebird house. Last year the sparrows wouldn't go thru it. This year the sparrows made a nest in it. Didn't think they would go through that tunnel. Cleaned out the box & will monitor it to keep it cleaned out. Will the bluebirds come back? What should I do now? Thanks, Mary
If a bluebird
family has already started to make a house and sparrows are harassing them you
can put up a sparrow
spooker. Basically once the bluebirds are committed to a nesting site you
can hang shiny flutter ribbon above the birdhouse (you can find this
"scare tape" at our stores). Studies have shown that certain bird
species, including house sparrows, will not fly under the ribbon. For more
detailed plans to make your own sparrow spooker, click HERE to visit the very
informative Sialis.org website.
Another possibility is to put two bluebird boxes within a
few feet of each other. Bluebirds defend large feeding territories around their
nests from other bluebirds. Experts recommend that bluebird boxes be spaced at
least 300' apart. However when you pair bluebird houses within 10 feet of each
other, it is possible to get a bluebird in one and a Tree Swallow in the other.
Together the birds can coexist and battle any predators or interloping
sparrows. More information on this technique can be found HERE.
Bluebirds and other cavity nesting birds typically begin
nesting in March depending on where you live. But they usually have more
one brood per season and may switch to a new site for their second
brood. Or if the birds' first nesting is unsuccessful, perhaps due to
other predators, they may move in to your nest box. Don’t lose hope.
You can put bird houses up year round because some birds
will even use the boxes as roosting sites in the winter.
