Swallows were poisoned by catching pests and eating pesticides. What do you think of this? What does this tell you?

In fact, swallow pesticide poisoning is very rare, because swallows hunt in the air and mainly eat flying insects. An insect that has been exposed to pesticides will not fly to the sky, but just wander around on the ground, and many pesticides have a very unpleasant smell, so swallows will stay away after smelling them.

Even if some people say that 80% is for hype.

Even if you see a dead swallow, where is it? How to prove that swallows were poisoned by pesticides? Is there a scientific basis?

Birds such as magpies, crows, snipes and field owls die every year because of eating insects contaminated by pesticides, but it is difficult for swallows to eat insects contaminated by pesticides.

But in comparison, the number of birds poisoned and killed by eating insects poisoned by pesticides every year is nine Niu Yi hairs compared with the number of birds illegally killed by human beings.

Therefore, if the landlord really loves birds, he will spend his time studying the incident of pesticide poisoning birds and stop some bird catchers from killing them indiscriminately, then the effect of protecting birds will be greatly improved! !
