Read: Open-field research with clubbing to death - for allegedly scientific research purposes, corvids are being killed in Leer to investigate the effects on the population of ground-nesting birds and small game. Yes, the Hannover University of Applied Sciences actually thinks that they need to kill animals in large numbers for this. By the way, the traps not only kill corvids but also severely injure birds of prey when they are caught. One might also think that there are enough corvids around, but a whole series of birds of prey are seriously endangered.
There is no idea so stupid that it couldn't occur to someone and others let themselves be harnessed to such a cart.
