Use Of Decoy Traps To Protect Blueberries From Juvenile European Starlings, Michael R. Conover, Richard A. Dolbeer
Use Of Decoy Traps To Protect Blueberries From Juvenile European Starlings, Michael R. Conover, Richard A. Dolbeer
Human–Wildlife Interactions
Fruit consumption by large flocks of juvenile European starlings (Sturnus vulgaris) is a serious problem for growers of strawberries, grapes, apples, cherries, blueberries, and other small fruit. This study examined if numbers of juvenile European starlings foraging in blueberry orchards could be reduced by catching them in decoy traps and relocating the birds elsewhere. From late July through August of 1989, 620 juvenile starlings were captured in 2 decoy traps at a blueberry orchard in Connecticut. A similar number were caught during the same period in 1990. During these 2 years, numbers of juvenile starlings foraging daily in …

Use Of Snares To Live-Capture Beavers, Lance B. Mcnew, Jr., Clayton K. Nielson, Craig K. Bloomquist
Human–Wildlife Interactions
Wildlife managers, researchers, and nuisance-control operators often require a nonlethal means of capturing beavers (Castor canadensis). Historically, live-capture has relied on enclosure-type traps such as Bailey or Hancock traps. We describe the live-capture of 231 beavers using snares in southern Illinois from 2002 to 2005. Capture success averaged 5.4 beavers/100 trap-nights. Capture success did not differ between sexes (P = 0.57) or age-classes (P = 0.68). We captured most beavers in haul-out slide sets, surface run sets, or channel sets. Recaptures accounted for 28% (n = 65) of all captures. Mortality rate using snares was 10% and decreased …
