I saw this, and am very happy for the Australians that have pushed for this for so long and hope more and more places follow in kind!
A few weeks ago, I had shared some data from the US, where SGARs are fairly unregulated, and multiple studies show 80-100% of different raptor species that have been tested show some level of secondary poisoning.
For those not in the know, old rodent poison would metabolize in 1-4 weeks, and unless a bird was really unlucky, they wouldn't likely get dangerous levels of poison from eating poisoned rodents. Modern poisons are much higher in toxicity, killing many rodents within hours of eating poisoned bait, making each rodent much more dangerous to hungry birds, and additionally it can take a year+ to break down in the body, so higher levels of poison are ingested each time and it accumulates in their bodies if the first dose doesn't kill them as it is.
Poisoning is an ugly and painful way to die. Seeing these animals go through this is terrible for those of us that try and save them. These birds don't reproduce in great numbers, they unknowingly eat these poisons themselves, and they bring them home to feed their nestlings. Raptors fill crucial roles in our environments, and they need to be protected.
