Although the cost/precision balance is an important topic, it would carry too far in this article to address these issues (see [48, 50, 62, 64, 69, 88], , pp. 371-372, and , pp. 977-979). However, two- or three-phase sampling are generally acceptable on economic and logistical grounds, and seems to provide a reasonable trade-off between additional mailing costs for multiple mailing waves, bias attenuation and increase of the sampling variance (since the sampling variance increases with the number of phases). In the case of a postseason survey conducted with an annual periodicity, in our experience, the success of the strategy we advocate in this article depends on several critical factors. First, the quality of the sampling frame is one of the most relevant prerequisites, both in terms of coverage and correctness of contact information (postal address and phone numbers). Second, it is of the utmost importance that designing the questionnaire (either paper- or web-based) as well as receiving and processing the questionnaires be accomplished by the wildlife agency itself. We strongly advise against relying on unskilled organizations regarding hunting surveys such as market research organizations or opinion poll organizations: only printing and mailing could be outsourced. Third, the timing of mailing waves and of the last phase phone interview must be carefully planned and respected. Fourth, entry and control of the hunting bags reported (questionnaires completed) must be carried out on a continuous flow basis. Of course, is it possible that one or two surveys be necessary before entering in a perfectly mastered routine, but we think that the quality of the hunting bag estimating scheme worths these efforts.
