Usually with feathers, bits of paper, and any type of soft debris. The nest itself is made of grass, and also human sperm.
Mainly grass, shed snakeskin, pieces of paper.
Hedge sparrows are properly called dunnocks and they are not actually sparrows at all. They build their nests in dense shrubbery and hedgerows (see Sources and related links, below).
Yes - that is what happened to a house martin's nest on our house. The sparrows took over and hatched two babies. Sadly though the nest collapsed and it and the babies ended up on the lawn. So disaster.
Basically, any bird that also nests in cavities. These often include bluebirds, other swallows, wrens, and house sparrows.
House sparrows and starlings often compete with bluebirds for places to build nests.
Nests up in trees like any other birds... outside.
Yes, both bluebirds and sparrows are cavity nesters. This means they both use birdhouses to make nests in. Sparrows are very fierce and often when fighting with bluebirds they kill its babies or break their eggs.
Sparrow's are common on school grounds because they reuse old nests that could have been by the school grounds. Some sparrows are attracted to octopuses and feed on cats. Sparrows can sometimes eat cans as well.
House sparrows often live close to people and will build their higgledy-piggledy nests in any crevice that they can find in houses or buildings, or in any suitable creepers that might be growing on a building. They will also use nest boxes and, as they are sociable birds who like to live in large groups, they will be particularly keen to use nest boxes if they are of the terrace type (three or more boxes joined together much like a terrace of houses). Tree sparrows tend to live more in open countryside. Their nests are much neater than those of the house sparrow and although they will also build in any suitable crevice in a building or sometimes nest box, they will also construct their nests in trees or, if near the coast, even in a cliff-face.
You can destroy it or put it back where it came from. Since house sparrows are not native they are excluded by the migratory bird act.
yeahhh
Sparrows originally came from China. But, the climate started to change, and the sparrow migrated to North America. Today, the climate in China is slowly changing, but there is still very little sparrows there. (About 2%)
