Updated December, 2025 NEST SITES: ACTIVE NESTSITES: The nest status was reported as Occupied Failed or Occupied Intact in the last 5 years. INACTIVE NESTSITES: The nest status was reported as Unoccupied Intact or Unoccupied Dilapidated in the last 5 years. UNDETERMINED NESTSITES: The nest status was reported with an Undetermined status in the last 5 years. DESTROYED: The nest status was reported as Destroyed in the last monitoring record. UNKNOWN NESTSITES: The nest does not have a recorded monitoring record in over 5 years. FORAGING AREA: Open water areas, typically associated with larger rivers, lakes, and reservoirs with abundant fish populations, utilized by both resident and transient osprey for feeding purposes. This information was derived from Colorado Parks and Wildlife field personnel. Data was captured by digitizing through a SmartBoard Interactive Whiteboard using topographic maps and NAIP imagery at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). These data are updated on a four year rotation with one of the four Colorado Parks and Wildlife Regions updated each year. These data are not updated on a statewide level annually.2025年12月更新 巢址（Nest Sites）： 活跃巢址（ACTIVE NESTSITES）：过去5年内，巢体状态被记录为“已占用失败（Occupied Failed）”或“已占用完好（Occupied Intact）”。 非活跃巢址（INACTIVE NESTSITES）：过去5年内，巢体状态被记录为“未占用完好（Unoccupied Intact）”或“未占用破败（Unoccupied Dilapidated）”。 待定巢址（UNDETERMINED NESTSITES）：过去5年内，巢体状态被记录为“未确定（Undetermined）”。 已损毁巢址（DESTROYED）：最新一次监测记录中，巢体状态被记录为“已损毁（Destroyed）”。 未知巢址（UNKNOWN NESTSITES）：该巢址已超过5年无有效监测记录。 觅食区（FORAGING AREA）：指开阔水域，通常与鱼类资源丰富的大型河流、湖泊及水库相关，为居留性和迁徙性鹗（osprey）提供觅食场所。本数据源自科罗拉多州公园与野生动物管理局（Colorado Parks and Wildlife）野外工作人员。 数据通过SmartBoard智能交互白板（SmartBoard Interactive Whiteboard）对不同比例尺的地形图及美国农业影像计划（NAIP, National Agriculture Imagery Program）影像进行数字化采集，相关方法引自Cowardin, M., M. Flenner. 2003年3月. 《Maximizing Mapping Resources》. 《GeoWorld》 16(3):32-35。 本数据采用4年轮换更新机制，每年更新科罗拉多州公园与野生动物管理局下辖4个区域中的1个区域，并非每年开展全州范围的数据更新。
