Once rare birds are returning - Catherine - 09-10-2025
In North America, many birds declined in number because of pesticide use, hunting and habitat loss.
Some, like the Passenger Pigeon, have gone extinct. Banning of DDT helped bring back bird numbers. A decline in hunting certain species has helped.
Restoring habitat is the biggest positive effect. The birds have somewhere to live and this has allowed their numbers to thrive again.

When we undo the harms we have done to species of birds there is a positive effect.
Without DDT, more chicks are able to survive to hatching. Not hunting them means there are more adults to breed and increase their numbers.
Restoring habitat means there is somewhere for birds to raise their chicks. These all result in the increase in bird numbers we are seeing.
This is only in some areas and some species, but it shows that we can make things better. I hope these efforts spread and help more species to do better.
