Our specific objectives were to (a) estimate detection probabilities of nocturnal bird species, after taking into account survey‐specific covariates, and (b) investigate the influence of site‐specific covariates on owl and nightjar abundance, integrating effects of imperfect detection.

最大化检测概率，以进行有效的大规模夜间鸟类监视

我们的具体目标是（a）在考虑了调查特定的协变量之后，估计夜间鸟类的检测概率；（b）研究地点特定的协变量对猫头鹰和夜鹰丰度的影响，并整合不完善检测的影响。
