Experts have written the 188 detailed accounts of species that spend all or some of the year in Britain & Ireland.

What is a bird atlas project?

A typical bird atlas project collates data on bird presence or abundance with mapping of this information over a significant geographical region over a well-defined period of time. Data gathered in other efforts, such as breeding bird surveys and eBird, may also contribute to atlas projects.

What is the cycle of migration?

Migration is often annual and is closely linked with the cyclic pattern of the seasons. It is most evident among birds, which have a highly efficient means for traveling swiftly over long distances. The migration of most birds is a yearly cycle.

What is EurIng doing with its bird migration data?

This in turn facilitates a wide range of large-scale analyses, including the Eurasian African Bird Migration Atlas that is currently under development. A team of volunteers, led by EURING Data management Committee Chair Chris du Feu, has just published the latest version of the code.

How many eBird checklists has the New Zealand bird atlas received?

To date the New Zealand Bird Atlas has received over 203,000 complete eBird checklists, submitted by nearly 1100 Atlasers. December 2021 represented the halfway mark of the NZ Bird Atlas project.

When did birds start migrating?

The roots of the migratory habits of modern birds are believed to date back millions of years, and were tempered by environmental changes caused by the Ice Ages of the Quaternary period over the last 2,500,000 years. Migration, as is known among modern birds, probably developed gradually by stages.

What are the eBird bar charts based on?

eBird bar charts are based on frequency: the percentage of checklists reporting that species within a specified date range and region. Thus, taller bars indicate a species is reported on a large proportion of checklists from that area and time of year.

What is the Atlas of breeding birds?

The Atlas of Breeding Birds in Britain and Ireland was organised by the British Trust for Ornithology (BTO) and Irish Wildbird Conservancy (IWC) and organised by Tim Sharrock (Sharrock 1976).

What can bird atlases tell us about the environment?

Since the first one was completed in Great Britain in the 1960s, bird atlases have become one of the most valuable tools for tracking environmental change—a tool that has allowed biologists and land managers to make wiser conservation decisions.

Are there any data sets on bird distribution in New Zealand?

The only data sets that have recorded the spatial distributions of all bird species across the whole of New Zealand are the two national atlases of bird distribution compiled by the Ornithological Society of New Zealand (OSNZ; Bull et al. 1985; Robertson et al. 2007, also known as Birds New Zealand).
