BTO Atlas & Devon Atlas

Devon Atlas News

The BTO Atlas project, which has been running since 2007 will end this year (2011).

However, DBWPS has initiated a Devon Atlas Project that will continue to run until 2013 and will eventually lead to the publication of an Devon Atlas, as Volume 2 of the Birds of Devon published last year (2010).

The Devon Atlas Group can be found on its own web site at Devon Atlas web site. .

SMADD 2009 Survey

Peter Dare and Pete Reay are looking forward to receiving your Summer Migrant Arrival and Departure Dates in Devon (SMADD) pilot survey records. Even if you only have one date for one species, please send it in, as the responses to the pilot survey will help decide the scope of the full survey (due to start with summer migrant arrivals in 2010), and what modifications to the survey may be needed.

Early-singing Blackcaps – records please!

9 April 2009

Last year, Peter Goodfellow heard his earliest-ever singing Blackcap, in February. In that month’s Harrier, Peter appealed for other records from Devon, but none were received – until his own record this year: a Blackcap that sang loudly twice from a thicket of pussy willow in his garden at 10.45am on 7 March.

Bird Atlas in Devon – a special progress report

20 February 2009

The late Mark Blacksell and late John Woodland worked tirelessly to recruit and encourage birdwatchers across Devon to participate in the national BTO Atlas by taking on tetrads for timed counts and to make a note of their casual records. In a special report for the Devon Birds website, National Coordinator DAWN BALMER reports on progress with the survey in Devon.

BTO Atlas - Update 3

What a fantastic response from Devon birders

Revised text of a John Woodland report from August 2008

The last published Atlas is 20 years old and increasingly out of date. Atlasses are one of the main tools used by conservationists to identify and underpin the actions that need to be taken to protect the natural environment. The need to update the 1988-91 Atlas is therefore paramount. Thus, in 2007, the British Trust for Ornithology (BTO), together with BirdWatch Ireland (BWI) and the Scottish Ornithologists’ Club (SOC) embarked upon this mammoth task, one that will take four years to complete.

BTO Atlas - Update 2 - Early Findings

Early findings

Revised text of a John Woodland report of April 2008

The submission of Atlas records on-line allows the BTO very quickly to build a picture of the distributions of birds. The orange dots on the maps below are based entirely on records submitted to the website as Roving Records and Timed Tetrad Visits and show presence in a 10-km square. However, these maps do not show the complete picture; it will take four years to do that!

 

BTO Atlas - Update 1

Thirty one million birds counted so far.

November 2007 saw the start of the biggest survey ever to take place in the UK. A new “Winter” atlas and a new “Breeding” atlas will result after 4 years fieldwork during 2007-2011.

Devon List & Checklist

The Devon List & Checklist – Introduction

Introduction

There are two lists available from this page.

List 1 – Devon List

The first list is a standard Devon List, similar to those presented in the Devon Bird Report each year. The only change from the usual DBR format is the lack of BOLD type to denote a species seen in the current year. This is fully covered by the fact that any species that does NOT have a year appended to the end of the line has been seen in the current year.

Fieldwork

Pete Reay, 2006

To further the study of birds in the field – a DBWPS objective.

The stated objectives of the Society are ‘to further the study of birds in the field and to assist in their conservation’. Study and conservation are distinct areas of activity, but are closely linked because it is generally acknowledged that the most effective conservation is based on sound study. Nevertheless, it is perfectly acceptable to study birds purely out of interest and independent of any application in conservation; one example here might be recording the passage of seabirds from headlands.

Fieldwork Projects

Pete Reay, February 2006

The National Surveys listing is being brought up to date and will be posted very soon. In the meantime this is the list as published by the Fieldwork Planning Group in 2006.
