County Avifauna

A new avifauna for Cumbria is planned for publication in approximately 2018.  This will be based on the Bird Atlas survey work carried out between 2007 and 2012.  Copies of our previous atlas are available here: The Breeding Birds of Cumbria: a tetrad atlas 1997-2001.

The following maps are based on the data received from the BTO for 2007 to 2011 and the Cumbria Breeding Atlas 1997-2001.  These maps are to be regarded as preliminary maps only and are intended to give a flavour of what we have achieved so far.  Hopefully they will also inspire you to spend some time having a go at filling in the gaps for these and other species during the forthcoming breeding season.

These maps have been produced using data from both timed tetrads and roving records. Some data submitted for these tetrads will not have been included as they will have been processed after the date when this data was generated. Some of the data has still to be validated and will include unchecked data and some passage migrants particularly in coastal areas.

The maps were produced by Stephen Westerberg using DMap software.

Winters 2007-2011

These maps show the distribution and abundance of a species during winter:

Breeding distribution changes

These maps show the change in breeding distribution compared to the 1997-2001 Altas.  Tetrads where species were found before but have not been found now are shown in grey.  Tetrads where species were not found before but have been found now are shown in red.  Tetrads where species were found in both surveys are shown in blue.

Breeding distribution changes #1

These maps show the change in breeding distribution compared to the 1997-2001 Altas.  Tetrads where species were found before but have not been found now are shown in pink.

Breeding distribution changes #2

These maps show the change in breeding distribution compared to the 1997-2001 Altas.  Tetrads where species were found before but have not been found now are shown in grey.  Tetrads where species were not found before but have been found now are shown in pink.  Tetrads where species were found in both surveys are shown in red.
