森林砍伐和狩猎是导致易受伤害的大凤冠鸟（Crax rubra）和濒临灭绝的大Tinamou（Tinamus major）种群数量下降的主要人为干扰。这些威胁通常同时发生，具有协同效应。我们调查了栖息地使用的大凤冠鹦鹉和大Tinamous在马塔帕洛走廊的奥萨半岛，西南哥斯达黎加，在那里他们不被猎杀，了解是否干扰栖息地可以适合这些物种。我们分析了相机陷阱数据从56个地点和5579诱捕天使用占用建模。我们在56个地点中的33个（59%）获得了195次独立捕获的大凤冠鹦鹉，在56个地点中的37个（66%）获得了429次独立捕获的大蒂纳姆斯。大凤冠雉占用率并不随栖息地类型而变化，但受到距离道路和海拔的负面影响;检测概率随栖息地类型而变化。大Tinamou占用概率主要与栖息地类型，初级，次生林和种植园林地区都表现出高占用概率，但占用农业用地是低的。我们的工作表明，次生森林可以提供宝贵的补充栖息地，以帮助恢复这些下降的物种，至少当狩猎受到控制，附近有完整的森林。
ABSTRACT Deforestation and hunting are the leading human-driven disturbances causing population declines of the vulnerable Great Curassow (Crax rubra) and the near threatened Great Tinamou (Tinamus major). These threats typically co-occur, with synergistic effects. We investigated habitat use of Great Curassows and Great Tinamous in the Matapalo corridor of the Osa Peninsula, southwest Costa Rica, where they are not hunted, to understand whether disturbed habitats can be suitable for these species. We analyzed camera trap data from 56 locations and 5579 trapping days using occupancy modeling. We obtained 195 independent captures of Great Curassows at 33 of 56 locations (59%) and 429 independent captures of Great Tinamous at 37 of 56 locations (66%). Great Curassow occupancy did not vary with habitat type but was negatively influenced by distance from roads and by elevation; detection probability varied with habitat type. Great Tinamou occupancy probability was principally related to habitat type; primary, secondary and plantation forest areas all displayed high occupancy probabilities, but occupancy of agricultural land was low. Our work suggests that secondary-growth forests can offer valuable complementary habitat to assist in the recovery of these declining species, at least when hunting is controlled and intact forests are nearby.
