Backyard Bird Feeding & Avian Flu

  • May 6, 2022
  • Written by Audra Cooper

The H5N1 subtype of Avian Influenza virus is spreading in Canada. It is causing severe illness and mortality in domestic poultry flocks and has been detected in waterfowl and birds of prey. It is not currently considered a disease threat to songbirds, including species that frequent backyard feeders.

As of April 27, 2022, Environment and Climate Change Canada advises that the use of bird feeders is still safe on properties without domestic poultry. Since the situation is ever-changing, check out their webpage for the latest information and directives. https://www.canada.ca/en/environment-climate-change/services/migratory-game-bird-hunting/avian-influenza-wild-birds.html

To Minimize Risk:

  1. Prevent over-crowding at feeding stations: It is quite easy to minimize over-crowding at this time of year because Common Redpolls, which are the most common and widespread flock species in Alberta & Saskatchewan, have departed for their northern breeding grounds. The only other species that tend to flock in large numbers at this time of year are the non-native House Sparrows. To encourage resident House Sparrows to disperse (at least until the situation has stabilized), avoid offering mixes that contain millet, corn and milo. Instead, offer suet mixtures, peanut butter mixtures, and/or sunflower chips from tube feeders that have small portals. Even better use upside down tube feeders because House Sparrows cannot access the seeds from an upside-down position.

The other way to prevent over-crowding is to place feeders farther apart around your yard. Wide spacing of feeders will enable the less dominant birds to feed (reducing their wait times at crowded feeders, thus resulting in fewer concentrated droppings) and will result in fewer birds at each feeder.  If possible, move the feeders to new locations each week to minimize waste accumulating on the ground.

  1. Sanitation: Diseases spread between feeder birds through direct contact and via contaminated feces and saliva. Replacing tray feeders with tube and hopper feeders will reduce the risk of birds contacting each other and will prevent fecal contamination.

It is also important to keep feeding stations clean by washing them (including the perches) once a week with hot soapy water and/or a diluted bleach solution (1 part bleach to 9 parts water). Air dry them before adding more seed.

Cleaning the area under feeding stations is also important. While many ground-feeding birds, especially migrating native sparrows, prefer to feed on the ground, it is important to rake up the detritus that has accumulated over the winter. To reduce further accumulation, serve sunflower chips or “no mess” mixes containing only shelled seeds.

If you observe sick or dead birds. There is little you can do to help a bird once it has become ill. If feasible, stay with the bird (so it doesn’t disappear) and call your local wildlife rehabilitation center (see links below). Wildlife rehabbers follow strict protocols that have been provided to them by the Canadian Wildlife Service. Never touch a sick bird with your bare hands. If the bird has died, use rubber gloves to place it in a plastic bag. Place it in a second bag and dispose of it with household garbage. Sick and dead birds can also be reported to the Canadian Wildlife Health Cooperative information line at 1-800-567-2033 or by using their online reporting tool.

  • Be proactive! The most significant contribution that individual landowners can make to supporting and conserving birds and other native wildlife is to provide habitat. High quality habitat (space within which wild creatures can find food, water and shelter) can be offered, even in small yards and gardens. Now is the perfect time to plan and start transforming your yard into a safe and healthy haven for our wild neighbors!
