New online Devon Bird Atlas launched

In January 2016, the Devon Bird Atlas was launched to great acclaim. It’s a 500 page reference work that documents all the breeding and wintering birds found in every tetrad across the county. A tetrad is a 2x2km square and Devon has 1,858 of them. Hundreds of volunteers spent thousands of hours in the field over a seven year period from 2001-2013.

Since launch, the Atlas has become a key driver of a number of important conservation projects. It highlighted for the first time the declines suffered by many of our birds in the thirty years since the last Atlas was published.

In fact, the information is so vital for conservation that Devon Birds took the decision to make it more widely available in an online version with open access for all.

Take a look at it here:

Most people will want to start with the Species Maps, shown here for Lapwing.

You can see that the page gives an overview of the current status of the species, current breeding distribution and then in the smaller maps, the breeding abundance and winter abundance. Clearly, we have many more Lapwing overwintering than breeding.

Now take a look at the Tetrad maps.

Here it’s possible to see what’s happened to Lapwing in Devon. And because it’s visual it has even more impact than the bald statistic that Lapwing have declined by over 90 per cent in just thirty years.
