Abundance, Distribution, and Threats of Grey Parrots in Nigeria

This dataset, collected in 2018/19, presents information on the abundance, distribution, and threats to African Grey Parrots in Nigeria. We provide details on the locations and types of habitats where African Grey Parrots have been recently sighted. The distance of each habitat to the nearest mangrove, an important breeding site for the parrots, is also included. The habitats are grouped under the following categories: Cross River Forest Area (CRFA), Niger Delta Creek (NDC), Western Forest Area (WFA), and Lower North-East Forest Area (LNEFA). Information on encounter rates of the parrots across the two seasons—rainy and dry—was provided, along with the seasonal variations in abundance and perceived threats as reported by community members living near the forest sites where the surveys were conducted. In addition to the perceived threats, we provided information on onsite observations of the threats, including trapping of adult individuals, nest poaching of juveniles, logging, and hunting, to reveal the spatial variations of these threats.本数据集采集于2018至2019年，收录了尼日利亚境内非洲灰鹦鹉（African Grey Parrot）的种群丰度、分布情况及其所面临的威胁相关信息。本数据集详细记录了近期观测到非洲灰鹦鹉的栖息地位置与类型，同时提供了各栖息地至距离其最近的红树林（该物种重要繁殖栖息地）的空间距离数据。所有栖息地被划分为以下四类：克罗斯河林区（Cross River Forest Area, CRFA）、尼日尔三角洲河汊（Niger Delta Creek, NDC）、西部林区（Western Forest Area, WFA）以及东北下林区（Lower North-East Forest Area, LNEFA）。数据集同时收录了雨季与旱季两个季节内的鹦鹉遇见率数据，以及调查林区周边社区居民反馈的种群丰度季节变化与感知到的威胁情况。除居民报告的感知威胁外，本数据集还纳入了实地观测得到的威胁信息，包括成鸟诱捕、幼鸟巢盗、伐木与狩猎，以揭示各类威胁的空间分布差异。
