Domestic cats are not really a problem if you look at the issue from a ecological point of view. Its the peoples thoughts about cats hunting birds which is the problem. Its literally impossible for the cat population to catch every single bird out there. So if the cats are catching millions of birds thats actually a very good sign that the bird population is at a very healthy level. With numbers being 2 to 3 to 4 times that of what cats are catching. Also yes maybe the cat can be considered an invasive species but many years have past and birds learn to deal with new predators over just 1 or 2 generations. The only time cats can be a issue is when for example a disease wipes out a large percentage of a single species. With cat densities being high, they can have a strong negative effect on that current species. But this again is not a big problem as cats are concentrated in urban area's even if they do wipe out a species in an urban environment that has had its numbers weakened the population surviving outside the urban area will re-populate the urban centers anyways. Cats are not an issue and to write an article about how devastating they are to bird populations on a whole is incorrect. Ofcourse there are acceptions but Canada has no cat problem regarding birds if you look at the big picture in ecological terms. New zealand is a small island thats a whole different story. Also what statistics fail to mention is a very large percentage of those birds taken by cats are sick, weak, injured, or young. These birds are going to die anyway so the cats are doing an important role in cleaning them up and keeping the bird population healthy and strong. These are just my thoughts on the issue.
I was thinking some of the same thoughts. I was thinking that cats are pushing birds to remain strong and vigilant. In a way cats are playing a role in all bird species' evolution. Or at least the ones they hunt. Those that fly faster and are more observant will survive and pass their genetics on to the next generation.
Also, yes cats are an invasive species but it was always going to be unavoidable. Cats have been part of our lives for 4000 years...there was no way, with immigrant populations coming to North America, that cats were not going to be introduced. Cats are not as loyal as dogs for instance and as such are much more likely to escape and become feral.
I think it's simply something that this bio-system has to adapt to and absorb. Of course, as a cat owner myself, I try to do my part to not make it worse ...so we do not let our cat out.
Well either way, I look forward to the article.
