The diversity and species abundance of bird communities are closely related to the structure and capacity of vegetation. The vegetation provides food, shelter, nest site, etc. for the birds. The effects of urbanization on avian habitat vegetation mainly include changes in vegetation structure and increases in foreign vegetation. In addition to high fragmentation of bird habitats in cities, canopy coverage in the middle and upper parts of the arbor forest is reduced compared to the natural environment. In an urban forest ecosystem, the species of birds feeding on the canopy, probing on the bark, may decrease in the bird community, while the species feeding on the ground may increase.
The avian community varies with the growth of exotic plants and their increasing proportion in the total amount of vegetation. The abundance and density of native bird species in the community is related to the native vegetation proportion, while the abundance and density of foreign bird species is related to the foreign vegetation proportion.
In cities, human activities can interfere with avian communities. Human interference with bird communities mainly includes man-made object collision, food acquisition mode change, predation, diseases, road interference and the like. Cities provide more food sources for birds, but also increase the risk of survival.
Seasonal variation of urban bird communities: the seasonal variation is closely related to the dynamic variation of the bird community, and the proportion of remaining birds to migrating birds in the community can be determined. During the most abundant and relatively scarce periods of the year, the resources that birds can acquire vary greatly, especially in colder winter areas, where more migratory birds are present in the bird community. In the city, due to factors such as a heat island effect and food sources provided by human beings, along with the improvement of the urbanization degree, the city provides a relatively mild microenvironment in cold winter, the seasonal environmental difference of the city center is reduced, the seasonal difference of the bird community is also reduced, and in addition, along with the reduction of the arbor coverage rate of the forest land in the city, the proportion of birds left in the bird community is increased, and the proportion of migrating birds is reduced. Thus, the abundance, and seasonal variation in composition of avian communities in cities are reduced.
The invention realizes the real-time monitoring of bird population density and provides data basis for the change of the regional ecological environment.
