2.0 deaths per home reporting kills. Six homes reported 10 or more bird deaths, 
     
     with two of the six accounting for 21 deaths each. 0f the 66 species killed in 
     
     window strikes last winter, most were common feeder visitors. The panic flights 
     
     of birds escaping raptors contributed to 16% of all reported window strike 
     
     kills. 
     
    

    
     The most frequently killed species died approximately in proportion to 
     
     their abundance at feeders. However, the five most over-represented 
     
     window-killed species were all woodland or tree loving species, namely the Pine 
     
     Grosbeak, Purple Finch, Downy Woodpecker, Hermit Thrush, and Cedar Waxwing. The 
     
     five most under-represented species included House Sparrow, Red-winged 
     
     Blackbird, European Starling, Blue Jay, and Chipping Sparrow. 
     
    

    
     If the data is extrapolated over the entire year, an estimate of 0.55 
     
     birds per FeederWatch home are killed in collisions with windows. The best 
     
     estimate to date before this study was that of Dr. Daniel Klem of the Southern 
     
     Illinois University who estimated that l to 10 birds are killed annually for 
     
     every building in the United States. 
     
    

    
     Dr. Klem has also conducted the first rigorous study of bird window-strike 
     
     prevention measures. Under his experimental conditions, commonly used 
     
     deterrents did not reduce window strikes. The most effective window guard 
     
     turned out to be a closely spaced grid of adhesive strips. However, few people 
     
     want to obscure their windows to this extent. Four different FeederWatchers 
     
     reported that plastic garden-protection netting installed about a foot away 
     
     from the window essentially solved their severe window strike problems. The 
     
     netting can be mounted in a frame similar to a window-screen to made 
     
     installation easy. ‘

     Editor's Note: The importance of the need for observations from at least 25 
     
     feeders cannot be over-stressed. The casual comments offered by observers to 
     
     the Island Naturalist and to the winter bird feeding workshops indicate large 
     
     differences between individual feeders. Project FeederNatch is an excellent 
     
     integation of volunteer birdwatcher sightings and scientific interpretation. 
     
     Efforts such as this will provide the basis of much of the information required 
     
     by species managers to aid species in trouble and meet multiple use objectives.
