Attwater's prairie-chicken (Tympanuchus cupido attwateri) populations have declined since 1970 and there is little information on their life history. Seventy-one radio-marked female Attwater's prairie-chickens (n = 54 nests) and 9 incidentally found nests provided information on nesting ecology between 1977 and 1981. The majority (74 %) of initial nests were started between 12 and 26 March and renesting continued into mid-May. Nest success of initial nests ranged from 19 to 64 % annually. Renesting success varied from 0 to 51 % and did not occur in 2 of 5 years. Obstruction of vision (OV) values were greater (P = 0.04) at successful (x = 2.46) than at unsuccessful (x = 2.16) nests |
