A new study finds steep, long-term losses across virtually all groups of birds in the U.S. and Canada
The Age of Plastics, y’all.
aka The End Time https://en.wikipedia.org/wiki/End_time
The main loss for birds comes from the loss of their food source, which comes from pesticides and land use of the agricultural sector.
That’s definitely part of it, but cats have been decimating bird populations for a long time. Cats are an invasive species in North America and none of the birds here have had any time to adapt. Cats are actually very destructive as invasive species.
That’s, as far as I know, still a very disputed claim with a big lack of evidence behind it.
Cars are a huge cat killer too, which is probably even more true in the US and their very high car dependency, which is probably also why you don’t hear much about it but rather have people scapegoat cats and other things.
