Herons - relative cranes. However, unlike cranes flying with outstretched neck, they bend the neck and tighten the head to the shoulders. There are about 60 species of herons. There they are on all continents except Antarctica.The most common kind in Europe - a gray heron. Now its population severely diminished. First herons were shot because of their addiction to fish today, they suffer from the reduction of wetlands and wet areas. To still surviving herons could safely grow offspring, forbidden to go into their nests.Cattle Egret (Bubulcus ibis) is different from the gray in that the upper part of the head, back and goiter in her wine-ocher color. This bird prefers to live in the vast swampy meadows. In the thick vegetation it builds a large nest of reed panicles. Masonry consists of 4-5 eggs.More than a century ago, the great white egret (Egretta alba) was almost destroyed because of the fashion egret - long feathers that adorned ladies' hats. For example, in 1898 only one in Venezuela, according to consular records, was removed from the egretok 1.5 million. Egrets.Installed in the 20-ies of XX century security egret with complete prohibition of hunting for it led to the restoration of the strength of this bird so that, for example, in our country it has become quite normal, and sometimes even a large bird.Black-crowned night heron (Nycticorax nycticorax) spends the daylight hours in the reeds or trees and only at dusk goes in search of food.

In my home town there are a lot of ecological problems. The people have many cars so the air in the area is quite polluted. There is a small river in town and some people take water from this river to wash their cars. So they return dirty water to the river. That is why the river is not safe to swim in. Also there are not enough rubbish containers in our town. That is why a lot of rubbish can be found in the streets and in the parks. Some people also throw rubbish where they want. We also have a factory near our town. The factory has big pipes from which dark clouds come. I think they also make air worse in my town. In addition to all this I think we have too few parks and green lawns. To make things worse, some people cut trees to make fires when they cook food in the open air.
