John Thomson: Get informed on feral cats and birds

I believe it is important that a response be given to the article entitled “Acreage owners could benefit from feral cats,” and the implications the article made regarding the benign effect feral cats have on wild bird populations.

It would be useful for anyone considering the introduction of feral cats onto their property, to first also consider studies that have addressed this issue, and to take into account the strong consensus among biologists and ornithologists about the negative impact outdoor/feral cats have on native birds. These studies and opinions reiterate the damage a concentration of feral cats can have on birds struggling to survive and reproduce in nature.

I’d suggest those wanting to explore this in more detail, go to websites such as The Cornel Lab of Ornithology or the American Bird Conservancy and search for articles addressing this “controversy” before placing feral cats onto your land.

I make this recommendation only in the hope that land owners make an informed decision.
