RENESTING OF WHITE-TAILED PTARMIGAN IN COLORADO
GIESEN KM and BRAUN CE. 1979. RENESTING OF WHITE-TAILED PTARMIGAN IN COLORADO. Condor
Renesting by free-ranging grouse has rarely been documented and few references discuss the importance of renests to chick production. Bump et al. (1947: 364) failed to document specific instances of renesting in Ruffed Grouse (Bbnasa umbellus) although thev estimated that 12% of all broods resulted from renkstings. Zwickel and Lance ( 1965 ) documented renesting in Blue Grouse ( Dendragapus obscurus); Maxson ( 1977) nrovided evidence of renestine bv Ruffed Grouse;’ Choate ( 1963: 113) described renesting by White-tailed Ptarmigan (Lagopus Zeucurus) in Montana. During 12 years ( 1966-1977) of intensive research on White-tailed Ptarmigan in Colorado we found two instances of renesting and have data available to estimate its importance to chick production.
