The following is thought of as the accident which the wildfowl suffers.
The poisoning …… agricultural chemicals, lead and organic compound
The crash …… Glass, electric light, voltage line, lighthouse, steel tower and net
The traffic accident …… car, train, and airplane
The others …… fuel oil pollution, barbed wire, fishing tool damage, and feeding in mistake.
Let's attempt to see about them, the glass crash, the traffic accident to happen in these,and the fishing tool damage which happen easily.
<The glass crash>
Birds collied with glass, because the scenery of trees, the sky and so on are reflected in glasses. They can see the opposite side with glass, too. A garden plant and so on are arranged indoors and it can be well seen from outside. It occurs frequently under the condition.
The glass crash tends to occur early in the morning. It seems to be possible to reduce a crash to the windowpane fairly by dropping blinds in the evening. Also,it is indispelsable to appeal for the architecture for which it is difficult to cause a crash accident, too, is indispensable.
The traffic accident
Carrying forward a research about the road structure and facilities not to cause a traffic accident. Studying a report system for birds that have an accident to grasp the actual state.
<The fishing tool damage>
There are some examples that the fishing tools which are fishlines, fishing needles, sinkers, and so on are causes of birds'death and damage. About the fishline birds are coiled by fishlines .They cause impaired blood circulation and natural amputation. There is an accident that the bird has swallowed a fishing needle and that it sticks in the leg, the bill and so on. There are lead poisoning which had swallowed a sinker and so on.
it is necessary to appeal for the danger widely.
