II Atlas of nesting birds - target species (1999-2005)

The Atlas of nesting birds from Portugal makes an inventory of 235 breeding species, from which 221 are native, and, among these, 205 with regular nesting activity. It covers a period from 1999 to 2005.

The project "Atlas of the Birds that Nest in Portugal" aimed to know the current distribution of breeding species in Mainland Portugal and in the autonomous regions of Madeira and the Azores and to characterize abundance, when possible, of national populations of these species, during the period of 1999 to 2005.

This dataset comprised two layers of information: Directed Census - Distribution data for bird species targeted by directed census, except Aquila adalberti, Aegypius monachus and Pterocles alchata whose location is confidential (includes marginal 10x10 km UTM squares);
Other species - distribution data for the remaining species (does not include UTM 10x10 km marginal grids).

The project involved the participation of ca. 500 volunteers, more than a dozen professional employees and various work teams in the organization. It is the result of a fundamental partnership with three other entities, namely the SPEA - Portuguese Society for the Study of Birds (a non-governmental association that works for the conservation of birds and their habitats in Portugal and which brings together numerous members interested in this faunal group); the Natural Park of Madeira (PNM) and the Regional Directorate for the Environment of the Azores (DRA), entities responsible for the conservation of wild birds in the autonomous regions.

《葡萄牙筑巢鸟类图鉴》收录了235种繁殖鸟类，其中221种为本地物种，其中205种具有规律性的筑巢活动。该图鉴涵盖1999年至2005年间的数据。

“葡萄牙筑巢鸟类图鉴”项目旨在了解1999至2005年间葡萄牙大陆、马德拉群岛和亚速尔群岛的繁殖鸟类当前分布情况，并在可能的情况下，对这些物种的国内种群丰度进行描述。

该数据集包含两层信息：定向普查 - 定向普查针对的鸟类物种的分布数据，不包括位置保密的 Aquila adalberti、Aegypius monachus 和 Pterocles alchata（包括边缘10x10 km的UTM网格）；其他物种 - 剩余物种的分布数据（不包括UTM 10x10 km的边缘网格）。

该项目涉及约500名志愿者的参与，超过十名专业员工以及多个工作团队的组织。它是与SPEA - 葡萄牙鸟类研究协会（一个致力于葡萄牙鸟类及其栖息地保护的非政府组织，汇集了众多对该动物群感兴趣的成员）、马德拉国家公园（PNM）和亚速尔群岛区域环境保护局（DRA）这三个实体基本合作的结果，这些实体负责自治区域的野生动物保护。
