Part A. Suppose year 1, immature, and adult birds have the same mortality rate, 0.086.

simulate_condor_population(0.086, 0.086, 0.086)

Part B. Suppose year 1 and immature birds have a mortality rate of 0.138, while adult condors have a mortality of half that amount, 0.069.

simulate_condor_population(0.138, 0.138, 0.069)

Part C. (Bustamante 1996) found a mortality of 65.9% for year-1 bearded vultures. Use this mortality and immature and adult mortality of 0.086.

simulate_condor_population(0.659, 0.086, 0.086)

Part D. Consider year 1, immature, and adult mortalities of 0.659, 0.138, and 0.069, respectively.

simulate_condor_population(0.659, 0.138, 0.069)

Part E. Consider year 1, immature, and adult mortalities of 0.659, 0.099, and 0.099, respectively.

simulate_condor_population(0.659, 0.099, 0.099)

Part F. Under the assumptions of Part d, suppose that a program of double-clutching persists for five years. Afterwards, all captive birds are returned to the wild. Compare the number of wild condors for this scenario to that in Part d.
