What harm does human harmful birds bring to human beings?

1. The main function of birds is to block or prevent the occurrence of pests, or to lengthen the interval between pests. Birds are not only the direct death factors of pests, but also indirectly affect pest populations by spreading insect pathogenic microorganisms or changing micro-habitats to affect parasites and predators.

2. Many birds are pollinators of flowering plants, such as hummingbirds, bees, sunbirds, woodpeckers, embroidered birds, snipes, toucans and parrots, and are often important pollinators of some flowering trees and shrubs. Without these birds, the ecological balance of nature may be seriously damaged.

Matters needing attention

Destroying grassland and wilderness or changing its land use form to grow crops, coupled with the use of pesticides, led to a large number of bird deaths.

At the same time, single farming, changing grazing methods and destroying natural vegetation and natural landscape have aggravated this influence. In addition, the report also lists the change of waterways, habitat fragmentation and human activities such as hunting, poisoning and poaching as special threats faced by birds.

The ecological protection in the Alps is good, but the biodiversity in the north (Norway, Finland, Baltic countries) and the Atlantic region (Britain, western France, Denmark and Benelux) is facing great threats.

People's Network-One third of the birds in Europe are endangered, and 80% of the habitats are in poor condition.
