Re: Bird collisions

Thanks for posting this Dan and as you say ¡°High time!¡±

The estimates of fatalities from window strikes in Canada and the US are from the and are likely underestimated.

?

I hear from lots of people about birds hitting their residential windows with the comment ¡°It was stunned but fortunately recovered and flew off¡± but research has shown that a collision can temporarily stun a bird and that even if it does flies off, seemingly recovered, many of these birds later die from broken bones, internal bleeding or bruising. Because of the sheer number of windows in residential homes, the toll on birds is greater than in commercial buildings which is why we¡¯ve been working to get people to take action by installing the 3M dots by Feather Friendly.

?

There has been a lot of focus on window strikes and migratory birds but birds that winter in Southwestern BC are exposed to mortality due to window collisions and other human related threats such as predation by cats, for at least half of their annual life cycle and birds like Varied thrushes are particularly vulnerable. Therefore, we have an increased responsibility to ensure our homes and businesses are bird-friendly!

Thanks again for posting!

An article about how some architects are trying to incorporate bird-friendly designs into buildings. High time! The article estimates that as many as a billion migrating birds are killed every year in North America from bulding collisions. That number seems awfully high, but the article doesn't say from whence that stat came. But whatever the number, it is a LOT!
