In aviation, the question is not what precautions are taken to save birds from being killed by aircraft, the question is what precautions are taken to prevent aircraft being hit by birds.
To prevent bird strikes at airports, several precautions will be taken.
Making birds not feel comfortable in the airport area
This will be achieved by doing following things:
Tall Grass The grass at airports is usually kept tall (> 25cm). This allows mice to hide and many birds, that rely on such food, can't see them.
Removing sources of food In the vicinity of the airport, all occurrences of the rowanberry will be removed. Birds have lost a big food source.
In some cases, fireworks are used to evict birds from the airport area. But this happens very rarely, because the birds can get used to it.
At Frankfurt airport, they have even brought ten foxes to live in the airport. They hope they eat most of the mice, so birds will find even less mice to eat.
Another system in Frankfurt detects big swarms of migratory birds flying over the Main River. Because the Main River crosses the approach on one runway, they always have to know if birds are flying over the river. The system detects swarms and calculates estimated arrival at the runway track. ATC will be automatically warned.
The pilot is also not responsible when innocent animals get killed. It is impossible to avoid a bird. It is usually not seen before impact as well. I talked with a drone pilot from the Austrian army once. He said the crew of an airplane needs around 10-13 seconds to detect an object, to be able to take action. A bird strike can be predicted maybe 1 second before impact. A pilot can do absolutely nothing.
It looks like you like birds very much, me too, but in aviation, human safety is always the first priority.
There are also no aircraft that are designed for bird safety. I can't even imagine how something like that could work. Sorry to say it: aviation has so many other more important things to consider. Saving birds' lives is not important in this industry.
