Description
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.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3,450 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section.

| Funding | This work was co-fund by ICNF, I.P. and the European Union, through the Environment Operational Programme (application 1.1/00021– Documentos Estruturantes da Conservação da Natureza e da Biodiversidade). The preparation of this resource for publication through GBIF was supported by Project PORBIOTA—Portuguese E-Infrastructure for Information and Research on Biodiversity (POCI-01-0145-FEDER-022127), under the Operational Thematic Program for Competitiveness and Internationalization (POCI), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (FEDER) and FCT. |
| Study Area Description | The roject was carried out in Mainland Portugal and in the autonomous regions of Madeira and the Azores. |
| Design Description | This atlas collected information on the distribution at a given time of the breeding species in mainland Portugal and in the autonomous regions of Madeira and the Azores. Whenever possible, they also characterize the abundance of national populations of these species. Moreover, information was classified according to nesting activities observed as: possibly nesting, confirmed nesting, no data. Atlas codes can be checked here: https://www.ebba2.info/atlas-codes/ |

Sampling Methods
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 characterise abundance, when possible, of national populations of these species, during the period of 1999 to 2005. Unsystematic and systematic recordings were carried out. For systematic there were 30-minute visits to 6 2x2 km tetrads of a 10x10 km grid. The attribution of the grids were the responsibility of the observer. The data allowed to estimate abundances relative to most species and enable systematic coverage of the territory. Also it directed censuses to know the dimension of the breeding population. These censuses were carried out in areas where the majority of the population was expected to occur. Individuals and/or couples outside these areas, also had the number of breeding individuals and couples recorded. 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).
| Study Extent | The geographic area considered for the original study was Mainland Portugal and in the autonomous regions of Madeira and the Azores. The species included are bird species that were observed regarding its nesting activities. |
|---|---|
| Quality Control | Data available was inserted in a specific relational database built specifically for the project, which implemented several quality control methods. In the preparation of the dataset for GBIF publication, data consistency was verified using cluster algorithms using OpenRefine. |
Method step description:
- 1. Aggregation of original data from several sources (see above) into a purpose specific relational database built for the project. For details, see Silva (2008). 2. Preparation of the dataset for GBIF publication used as source the geographic layer in shape file format. Although the data layer was a polygon layer with a 10 km grid, the attribute table contained, for the field records, original GPS coordinates with higher precision. In that case, the coordinates with higher spatial precision were considered. The following steps were performed: Conversion of the spatial layer to geographic coordinates using WGS84 as reference system to determine centroids of grid polygons; If the record contained coordinates in the database with higher precision, these were kept; Determination WKT for the polygons for which centroids were considered; Exporting to csv and reinterpretation to attributes to match DwC standard terms.
