Almost 3 billion birds lost! That's heart-breaking, but we can do something about it! Write to your representatives, make some changes in your own life, and share the news with family and friends. We can #bringbirdsback!

As a cat-allergic bird watcher, I am likely biased, but I see no benefit of an outdoor house cat. Spay, neuter, leash, and keep cats indoors. #birdnerd #birding https://t.co/C6N9aN79j1

On perdrait beaucoup d'oiseaux à l'échelle nord-américaine, selon cette étude. Vu de l'angle humain par contre, l'essor de l'ornithologie et la mobilité accrue fait en sorte qu'on n'a probablement jamais observé autant d'oiseaux. C'est compliqué. https://t

The decline in grassland birds I expected. Did not expect the decline in boreal birds!
Habitat loss. Pesticides. Feral cats. Grassland birds particularly badly affected. #habitatloss #environment #birds

First the depressing: North America has lost 2.9 BILLION birds (~29%) since 1970. A lot of this loss wasn't rare and endangered birds, it was common species like sparrows and starlings: the birds you see on your walks around your neighbourhood. https:/
