ABSTRACT Wildlife management often requires accurate estimates of hunter participation and species harvested. Sending pre-season hunting cards for recording activity can improve the accuracy of estimates. This research note examined the influence of record cards on the shape of waterfowl hunting survey response distributions. Data were obtained from a 2013–2014 mail survey of 1,796 waterfowl hunters in Illinois. Results indicated that individuals who received a record card were: (a) more likely to report small harvest and days hunting values (beginning of distribution), and (b) less likely to give responses that contributed to heaping (middle of distribution) compared to non-record card recipients. Record cards did not influence the end of the distribution, as frequency functions for all respondents were long-tailed distributions. Results imply that record card responses are more accurate than non-record card responses. Non-record card estimates were approximately 10% biased. Results supported continued use of record cards to limit bias.

提前通知记录卡对水禽狩猎参与和收获分布的影响

摘要 野生动物管理通常需要准确估计猎人的参与和收获的物种。发送季前狩猎卡记录活动可以提高估计的准确性。本研究笔记检查了记录卡对水禽狩猎调查响应分布形状的影响。数据来自 2013-2014 年对伊利诺伊州 1,796 名水禽猎人的邮件调查。结果表明，收到记录卡的个人：（a）更有可能报告小收获和狩猎天数（分布开始），和（b）与相比之下，不太可能给出有助于堆积的响应（分布中间）非记录卡收件人。记录卡不会影响分布的结束，因为所有受访者的频率函数都是长尾分布。结果意味着记录卡响应比非记录卡响应更准确。非记录卡估计有大约 10% 的偏差。结果支持继续使用记录卡来限制偏见。
