At one point in time, birds and urban wildlife were seen abundantly. Sparrow is one bird that we have grown up watching. But, in the recent past how many of you really remember seeing a sparrow? The current scenario is such that there has been an 80% decline in the population of sparrows due to many reasons such as habitat destruction, match box shaped buildings and changes in lifestyle.
Of late, there has been a destruction of habitat, native trees and green spaces which were vital for survival and ecological needs like nesting, feeding, roosting for sparrows. Due to large scale habitat destruction and alteration, cavity nesting birds like sparrows have lost cavities which were vital for nesting and raising their young ones.
Modern architecture made up of glass and aluminum composite panels are devoid of natural cavities or suitable habitat for urban birds and wildlife like sparrows. In such a scenario it is difficult for sparrows and other cavity nesting birds to find suitable habitat.
Change in lifestyle is one of the major reasons that has led to decline in the sparrow population. In earlier days, our grandmothers and mothers would sit in the verandah and clean cereals and grains. In this process, the leftovers and the worms were eaten by the birds. But now, we get pre-cleaned grains and cereals.
Exotic plantations has gained a lot of importance in the recent past. Exotic plants do not attract birds and other insects.
Cavity Nesting birds are those birds who live in cavities such as tree hollows or crevices of old buildings. They build their nest, lay eggs and raise their little ones inside them. The size, shape and placement of cavities vary
depending on the size of the birds.
