1921 Onward, Occupied Swift Nests, UK

<p>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&#39;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.</p>

该数据集旨在构建一个详尽的占据性普通雨燕（Apus apus）巢穴（雨燕曾在此使用巢穴洞穴）清单。数据收录自多个雨燕映射项目，包括《雨燕清单》、《雨燕调查》和《雨燕测绘》。这些项目的目标在于深入探究英国雨燕数量减少的原因，并协助定向保护雨燕巢穴。数据来源多样，主要包含公共信息征集和地方性调查。在2009至2015年期间，数据收集活动作为“雨燕清单”项目的一部分进行。这是一个合作项目，得到了苏格兰“关心雨燕组织”、伦敦雨燕、北爱尔兰雨燕、皇家鸟类保护协会（RSPB）、雨燕保护以及英国雨燕组织的支持。随后，从2016年至2019年，实施了“雨燕调查”，该调查为全国性调查，并开发了一个由环境资源管理（ERM）公司设计的网站，以收集公众关于巢居雨燕的数据。自2020年起，开始使用“雨燕测绘”工具进行数据收集。雨燕测绘是一个涉及皇家鸟类保护协会（RSPB）、自然才能、雨燕保护、雨燕行动以及地方性雨燕网络的测绘工具。2009年之前的数据由雨燕保护团体和RSPB调查提供。在自然生物多样性网络（NBN）上，还提供了巢箱、先前占用巢穴以及低级尖叫雨燕（可能为繁殖者）的伴随数据集。该数据集将每年更新。
