How can I stop birds from repeatedly hitting my windows?
Bird collisions with glass can occur for several reasons, reflection, transparency or for territory. Glass on our windows and doors can reflect surrounding vegetation or sky giving the illusion that it’s a landscape that birds can use. Transparency can also occur when a bird is able to see true habitat through a set of windows and perceives the space as a fly-through. For example, a transparency can occur at a corner where two panes of glass meet, or through a series of porch windows. Lastly, birds can hit glass because they see their reflection and believe another bird is encroaching on their territory.
There are simple, inexpensive, and attractive ways to help prevent any type of bird collision by making windows more visible to birds. To be effective, window patterns should be spaced in a 2-inch by 2-inch grid pattern and be placed on the outside of windows. For low-cost, temporary methods, individuals can make and hang a paracord bird curtain or create decorative patterns using tempera paint and stencils. For more long-term solutions, individuals can consider using dense decal markers (such as dots), external, or “fritted” glass that includes exterior patterns to make the glass visible to birds.

West Nile Virus is most often spread to humans from the bite of an infected mosquito. However, it’s always a good idea to follow basic hygienic procedures. Birdbaths and feeders should be washed or disinfected regularly. Wash your hands with soap and water after touching the baths/feeders. To prevent mosquitoes from breeding on your property, empty and clean birdbaths at least once a week and...

The U.S. Department of Agriculture implements a plan every year to monitor wild birds for highly pathogenic avian influenza. This national plan could not be implemented without the engagement of State partners, the National Flyway Council, the Department of the Interior, and other agencies. This coordinated effort is revised annually based on new science and data shared through the Interagency...

Oregon Songbirds: Singing for Their Supper in Evergreen ForestsIn this episode we sit down with USGS wildlife biologist Joan Hagar and discuss her recent study on songbirds in the Pacific Northwest. New research indicates a possible relationship between reductions in the abundance of some species of songbird and reductions in the amount of deciduous trees in evergreen forests.

Fitting a Bird with a Tiny Radio Transmitter
A captured bird is fitted with a tiny radio transmitter (designed to fall off after a few weeks) that allows it to be tracked, as well as gather data on the bird’s age, weight, fat load, wing size and shape, and general condition.
