The white-crowned Pigeon (WCPi), Patagioenas leucocephala, and the scaly-naped Pigeon (SNPi), P squamosa, are two Caribbean endemic species of patrimonial and cynegetic interest. Although both species are under the threat of habitat destruction and hunting pressure, population trends remain undocumented in a large part of their geographical range. Here, we used both the “auditory and visual” and “call-broadcast” census methods to assess the occurrence and relative abundance of both species in Guadeloupe (French West Indies). The call-broadcast method was found to be more efficient as it reduced the problem of “false absence” while increasing the probability of detection. Results from our surveys showed that both WCPis and SNPis were at low density and showed complete habitat segregation. SNPis were only encountered in rainforest, whereas WCPis could be observed at count stations located in dry and swamp forests, mangroves, agricultural lands and wet meadows. We recommend the use of the call-broadcast method for monitoring the two species on islands where they occur at low density, under which conditions distance sampling may be poorly reliable. The general relevance of the call-broadcast method to other species of pigeons and doves deserves further attention, especially to document population trends in elusive game species of conservation interest.

白冠鸽 (WCPi)、Patagioenas leucocephala和鳞枕鸽 (SNPi)、P squamosa，是两个加勒比地方性物种的世袭和 cynegetic 利益。尽管这两个物种都受到栖息地破坏和狩猎压力的威胁，但在其大部分地理范围内，人口趋势仍未得到记录。在这里，我们使用“听觉和视觉”和“呼叫广播”普查方法来评估瓜德罗普岛（法属西印度群岛）这两种物种的发生率和相对丰度。发现呼叫广播方法更有效，因为它减少了“假缺席”的问题，同时增加了检测概率。我们的调查结果表明，WCPis 和 SNPis 都处于低密度并显示出完全的栖息地隔离。SNPis 仅在热带雨林中遇到，而 WCPis 可以在位于干旱和沼泽森林、红树林、农田和潮湿的草地。我们建议使用呼叫广播方法在低密度的岛屿上监测这两种物种，在这种情况下，距离采样可能不太可靠。呼叫广播方法与其他鸽子和鸽子物种的普遍相关性值得进一步关注，特别是记录具有保护意义的难以捉摸的游戏物种的种群趋势。
