Because smaller song birds fly at lower altitudes they are more susceptible to the smoke, and will perish due to either smoke inhalation or exhaustion. With all the smoke in the air, I am sure much like myself that you are suffering from burning eyes and itchy, dry throats, imagine what it must be like to be a small bird. I would love to be able to save all the birds but it is just not possible, however, there are things you can do to help. First and foremost is water-clean and fresh everyday, with the amount of smoke and fires surrounding us now there is a lot of soot in the air and that falls into the water. The birds will use the water for drinking and bathing in order to keep their feathers clean. Also make sure that your feeders are clean and full of fresh food so that if they do manage to get to your yard they can refuel. If you do find birds or wildlife that require more help than you can offer please contact either Calgary Wildlife Rehabilitation or Alberta Wildlife Recovery.
