1921 Onward, Occupied Swift Nests, UK

The dataset is intended to be a comprehensive inventory of occupied common swift (Apus apus) nests (where swifts were observed using a nest site cavity).

It includes records collected as part of various swift mapping projects including The Swift Inventory, The Swift Survey and The Swift Mapper. The aim of these projects was to better understand the reasons for the decline in swifts in the UK, and to help target conservation of swift nest sites. They collated data from a variety of sources, primarily a public request for information and local surveys.

Between 2009-2015, records were collected as part of the ‘Swift Inventory’. This was a cooperative project involving the support of Concern for Swifts - Scotland, London's Swifts, Northern Ireland Swifts, the RSPB, Swift Conservation and UK Swifts.

The ‘Swift Survey’ then ran from 2016 -2019. This was a national survey, including a website developed by Environmental Resource Management (ERM) to collect data from the public on nesting swifts.

From 2020 onwards the ‘Swift Mapper’ tool has been used to collect records. The Swift Mapper is a mapping tool involving RSPB, Natural Apptitude, Swift Conservation, Action for Swifts and Swifts Local Network.

Records prior to 2009 were provided by swift conservation groups and RSPB surveys.

Accompanying datasets of nest boxes, previously occupied nests and low-level screaming swifts (probable breeders) are also available on the NBN.

This dataset will be updated annually.

本数据集旨在全面收录已被普通雨燕（Apus apus）占用的巢址记录，即观测到雨燕利用巢洞的位点。其数据源自多项雨燕相关测绘项目，包括雨燕名录（The Swift Inventory）、雨燕调查（The Swift Survey）以及雨燕绘图工具（The Swift Mapper）。上述项目的核心目标为深入探究英国境内雨燕种群数量下降的成因，并助力精准开展雨燕巢址保护工作。项目组从多渠道整合数据，主要来源为公众信息征集与本地实地调查。

2009年至2015年间，“雨燕名录”项目采集了相关记录。该合作项目得到了苏格兰雨燕保护协会（Concern for Swifts - Scotland）、伦敦雨燕保护组织（London's Swifts）、北爱尔兰雨燕保护组织（Northern Ireland Swifts）、英国皇家鸟类保护协会（RSPB）、雨燕保护协会（Swift Conservation）以及英国雨燕联盟（UK Swifts）的支持。

2016年至2019年，“雨燕调查”项目正式启动。这是一项全国性调查，由环境资源管理公司（ERM）开发专属网站，用于收集公众提交的雨燕筑巢相关数据。

2020年起，“雨燕绘图工具”（The Swift Mapper）被用于采集记录。该工具由英国皇家鸟类保护协会（RSPB）、Natural Apptitude、雨燕保护协会（Swift Conservation）、行动支持雨燕组织（Action for Swifts）以及本地雨燕网络（Swifts Local Network）联合开发运营。

2009年之前的记录由各雨燕保护团体与英国皇家鸟类保护协会（RSPB）的调查项目提供。此外，NBN平台还提供了配套数据集，涵盖巢箱、过往占用巢址以及低空鸣啼雨燕（疑似繁殖个体）的相关记录。本数据集将按年度进行更新。
