About those killer cats - [View all]

[hedgehog]

the real question is not whether carts are killing birds, but whether cats are responsible for an ongoing drop in bird populations. By comparison, we humans in the US kill millions of cattle every year, but what has caused a drop in the population is the ongoing drought: http://www.democraticunderground.com/1014387837

Presuming that bird populations have dropped and/or the distribution of bird species has changed, then the question is whether cats are a significant factor when compared to such causes as loss of habitat and/or pollution of habitat.

Which kills more birds: a domestic cat or a 1/4 acre suburban lot with a grass lawn monoculture, no cover, no water, no insects or seeds because it is chem-lawned?
