Provide supplementary food for gamebirds to increase adult survival
A controlled study on two 284 ha mixed-prairie sites in Oklahoma, USA, in 1992-6 (Townsend et al. 1999), found that northern bobwhites Colinus virginianus had higher winter survival in areas supplied with supplementary food in two out of four winters (19-31% survival of 423 fed birds vs. 3-13% of 396 controls), with lower survival in 1994-5 (11% of 200 vs. 22% of 188) and similar survival in 1995-6 (16% of 200 vs. 23% of 193). Twenty eight percent of seed in birds’ crops from the fed area consisted of supplementary food, compared with 6% in birds from the unfed area (783 birds examined). Food consisted of wheat, milo and millet provided in a 55 gallon barrel in the centre of each 8 ha section of the experimental area.
