#7 Sparrows are polygamous birds.
Having found a mate for themselves, they remain together for life. House Sparrow nests can be found in cracks in buildings, in house insulation, behind window casings.
#8 It is also common for sparrows to occupy abandoned hollows of animals and the dwellings of other birds.
#9 Wild birds often occupy the nests of larger birds such as eagles or storks. This is how small birds feel safe.
