The city parks and gardens in our cities and villages are inhabited by over 200 species of birds naturally occurring in the Bulgarian nature during the different seasons. Apart from the aesthetic and sensory delight they provide, the birds that live around us are among the most accurate indicators of the ecological health of the environment we inhabit.
Data from the country and abroad are quite alarming. In some European capitals, house sparrows have disappeared completely. In the last 10 years, the house sparrow has decreased by 50%, the common finch - by 44%, the woodpecker and the blackbird - by 35%, and the great tit - by 8%. It turns out that sparrows are missing from many European cities. Scientists claim that their population has decreased by more than 50% over the past 10 years in Bulgaria. They are of the opinion that the main reason for this sad statistic is the polluted environment. This is fully valid for big cities. According to the characteristics of sparrows, their main food is of animal origin. They forage for insects, small invertebrates as well as seeds. It is difficult for them to find this in the modern urban environment. It's all just cement and metal. Trees and gardens are quickly disappearing. Their inhabitants - the insects, the invertebrates - are also disappearing. The sparrows have nothing to eat and are also disappearing little by little.According to statistics, Londoners have not seen sparrows for 25 years. It is said that the reason for their disappearance from the British capital was the mass introduction of cars with diesel fuel in the early 1980s of the last century. The same can be said about the metropolis of Paris. They haven't seen sparrow representatives there for years either.
Definitely, the urban environment is not suitable for living for these birds. In addition to the lack of their main food - insects, seeds, invertebrates - sparrows cannot get used to the noise and overcrowding of cities. These widespread birds also help maintain ecological balance. They eat a huge amount of insects - some species swallow their own weight of insects every day. During the period of feeding their young, a family of titmice, for example, can eat several hundred kilograms of insects!
One of the ways to support the nesting of cavity-nesting insectivorous species, such as flycatchers, titmice, woodpeckers, woodpeckers and others, is to place artificial nests in parks and gardens. Another way is to place feeders and feed the birds that stay to winter in our country. During the cold winter months, it is difficult for birds to find natural foods such as fruits, insects, seeds, worms, and any additional nutrition can help them. You can also order from ours Feed for wild birds.
In addition to having substantial conservation value, these activities can be quite attractive to young and old people with a pronounced interest in nature conservation. We can change the course of the week by installing and maintaining a bird feeder in the winter, thus we will also raise our children in a responsible attitude towards our surroundings.
