Nesting Ecology of Attwater's Prairie-Chicken Academic Article uri icon

abstract

  • Tympanuchus cupido attwateri populations have declined since 1970. the majority (74%) of initial nests studied were started between 12 and 26 March and renesting continued into mid-May. Nest success of initial nests ranged from 19-64% annually. Renesting success varied from 0-51% and did not occur in two of five years. Obstruction of vision values were greater at successful than unsuccessful nests. Hen survival during the nesting period was not different. Survival averaged 36% (SE 0.08) during spring. Population declines are probably the result of low female survival during nesting and/or limited renesting success. -from Authors
