Reduce bird deaths through a few, simple, everyday actions
Keep your cat indoors."Aside from habitat loss, the next biggest cause of direct mortality for birds is outdoor cats," says Chu. One study estimates free-ranging domestic cats kill somewhere between 1.3-4 billion birds annually. Chu says she's seen people create enclosed patios, or "catios," so their cats can get outside time without posing a risk to birds. If you want to take your cat out, you can also try using cat leashes and cat backpacks to keep them close.
Chu also recommends putting on one of Cornell's live bird cams to keep your feline engaged and entertained while they're indoors."We found that cats love them as much as people do, and they'll sit and watch these live bird cams and they won't do any harm to the birds they watch," Chu says.
Make your windows more visible to birds to help reduce collisions. Window collisions kill up to a billion birds every year in the U.S. "A lot of people think that those collisions are occurring on high rise buildings, but most of the collisions are occurring at the lower levels of these high rise buildings," says Hallager. The American Bird Conservancy estimates 44% of bird window strike fatalities occur at homes or other buildings that are 1 to 3 stories tall.
To make your windows more visible to birds, you can try: 1. making DIY acopian blinds with string or parachute cord. 2. putting up window film with dots or lines. 3. adding a window screen or some kind of netting, set at least a couple inches from the window.
Turn off lights you're not using, especially at night and during times of high migration. "Many birds migrate at night. And as they go, they're attracted by light," says Chu. Lights will draw birds close to buildings, and sometimes, they collide. Bird collisions also happen during the daytime, because birds can't see glass. "So one of the things that you can help with, especially during migration, is to turn off any lights that are not used," Chu advises.
