In many cities of Ukraine, there is no longer to meet sparrows, such once familiar bird neighbors of people. However, scientists note that not only these little birds are at risk.
Ornithologist Natalya Chutkina says that tits, nightingales and other birds will disappear from cities due to chaotic development, excessive cutting of bushes and clearing bushes. In detail about threats for birds, the expert painted on her page on Facebook.
Birds disappear from cities, because nowhere to go, scientists say. At the site of the green zones, chaotic buildings arise, shrubs, trees, shrubs, which were a home for many feathered and other living organisms, are cut down.
Ornithologist Natalya Chutkina talks about the interaction of birds and vegetation in cities. She gives an example of Ivano-Frankivsk, where many species of birds live, extremely depending on the presence of vegetation. However, a similar situation is observed in all cities of Ukraine.
The expert notes that the city can no longer see Vorobyov, because they need thickets, shrubs. Most of their lives, these birds feed on plant foods and insects on plants.
" The nightingale is no longer heard, because there are no bushes with the lower branches - they were cut out, because it is " For the same reason, there will be no Olshanok, urticipers, ”says Chutkina.
"
" Once in the park I saw on one tree two of their nests on the lower branches. In wild natural conditions, these birds never nest on one tree, because it is stress. But in the city they are simply nowhere to go, ”the expert notes.
It is known that many birds nest in high grass. For example, a shepherd blacksmith is a small bird that makes a nest on the ground in the form of a large ball in thick grass. But the grass is actually cut off under the root, so that there is a beautiful city lawn.
" If the grass is one or two centimeters high, then the soil warms up a little less-35 degrees, ”explains Natalya Chutkina.
" This soil contains water, it becomes wet, the process of decay begins, accordingly there are different microorganisms, insects. That is why in the summer in the city it is so hot - the earth is overheated, because the grass was maximally bored with the grass, ”the ornithologist added.
The expert notes that for many birds a bush overgrown with high grass is a house, a cache, protection and a dining room at the same time. But the bush should not consist of a few twigs, masterfully cut and plucked, but should have the form of a cell where you can hide and build a nest and bring out the descendants.
For example, all types of urticarians nest in such bushes, drifts, finches, flycatches, nightingales and a dozen species, reports in his message, Drimatkin.
" For example, sakura, tulip trees, decorative plums beautifully bloom in spring in the spring, but these trees do not bear fruit, respectively, do not supply birds of the aft base, ”the ornithologists informs.
Researchers of urban ecosystems recommend planting native plant species, in particular Kalina, Rowan, hawthorn, barberry, currants, rosehip, thorn, spire, an elderberry.
These shrubs can be well beaten in landscape design, they, like all bushes, are pruning. Bushes can be formed without destroying the lower growth of branches and allowing birds to create nests there, experts note.
Natalya Khokatkina notes that in European cities they leave flower beds, on which field herbs and flowers for lure of insects and birds are planted. It is also forbidden to cut trees of any age or cut a branch until the tree examines the specialist.
" There is always a buffer zone around reservoirs - a territory without human intervention, fenced and approaching water in clearly defined places, ”the ornithologist said, noting that such experience should be adopted by Ukrainian cities and Ukrainian cities.
