Table 3. A comparison of the simulated dataset parameter estimates (standard errors) for a random singing model – constant random temporary emigration model, with observer dependent detection probabilities constant over time intervals. The population of birds that sing at least once in eight minutes is N = 100. Estimates and standard errors found with B = 500 bootstrap samples.
