量化鸟类种群的生产力通常涉及到从繁殖季节发现的鸟巢样本中计算鸟巢成功率。雌性繁殖产量（年度或一生）对鸟类的人口统计学建模很重要，但巢的成功是一个很差的指标来比较地区或种群之间的生产力。根据初步的审查，我们假设，鸟类文献区分不好每年繁殖成功的巢成功，无论物种的繁殖策略，和鸟类生产力的影响，renesting和多次育雏很少被承认。我们调查了经常发表鸟类学文献的9种期刊在81个期刊年的356篇文章中对巢穴成功、年度繁殖成功、繁殖和多次育雏的报道。我们发现，在356篇报道生产率估计值的文章中，有54%使用了巢成功的变化。然而，只有10%的文章报告了年生殖输出的估计。我们发现，28%的文章报道了所研究物种的繁殖策略，47%的文章承认了重新繁殖或多次繁殖的物种。没有时间增加，承认物种的繁殖策略，休养生息，或多育雏。我们的审查表明，巢成功和年度繁殖成功之间的区别不大。为了准确地支持保护评估，我们认为使用巢成功评估鸟类生产力必须严格审查。
Abstract Quantifying productivity of bird populations often involves calculating nest success from samples of nests found during a breeding season. Female reproductive output (annual or lifetime) is important to demographic modeling of birds, but nest success is a poor metric to compare productivity among areas or populations. Based on preliminary review, we hypothesized that avian literature poorly distinguishes annual reproductive success from nest success regardless of species' breeding strategies, and that the influence of renesting and multiple brooding on avian productivity is infrequently recognized. We investigated the reporting of nest success, annual reproductive success, renesting, and multiple brooding in 356 articles across 81 journal-years for nine journals that frequently publish ornithological literature. We found 54% of 356 articles reporting productivity estimators used variations of nest success. However, only 10% of articles reported estimates of annual reproductive output. We found that 28% of articles reported the breeding strategy of the species studied, and 47% acknowledged renesting or multi-brooded species. There was no temporal increase in acknowledgment of species' breeding strategy, renesting, or multi-brooding. Our review indicated little distinction between nest success and annual reproductive success. To accurately support conservation evaluations, we believe use of nest success in assessing avian productivity must be critically examined.
