Are you interested in birds? Can you tell a Blackbird from a Song Thrush, a Meadow Pipit from a Skylark, a Stonechat from a Whinchat? Would you like to contribute to a national survey on Arran?

The aim
A Bird Atlas is being organized by the British Trust for Ornithology.  It aims to produce maps of distribution and relative abundance for all bird species breeding and wintering in Britain and Ireland.  It will allow changes to be assessed in bird distributions since previous breeding atlases in 1970 and 1990, and since the last winter atlas of the early 1980s.

Getting involved
The survey work will span four winters and four breeding seasons, starting on 1 November 2007, during which the whole of Britain and Ireland will be surveyed.

Two methods of recording are being used.

1. Roving Records whatever you see, whenever, wherever!
For distribution maps to be comprehensive, complete species lists are needed for every 10-km square in Britain and Ireland for the breeding season and winter.  Roving Records are a means of submitting lists for all squares.  Anyone interested in birds can take part by supplying Roving Records of birds they see on Arran. 

2. Timed Tetrad Visits – concentrating on an area
Arran is covered by ten 10km squares on the Ordinance Survey Map. Each of these 10km squares has up to 25 tetrads (group of four 1km squares).  Eight tetrads in each 10km square are to be surveyed.

In winter the tetrad is surveyed for two 1 hour timed visits at a date and time of your choice, one early in the winter and one late.

In the breeding season the tetrad is surveyed for two 1 hour visits, at a date and time of your choice, one early in the breeding season and one late, noting signs of breeding.

The idea is to walk around the main habitats in the tetrad and record and count all the species.  Different routes can be used on the two visits so that all habitats are covered.  This will give information that will lead to the production of maps of distribution and relative abundance for all bird species breeding and wintering in Britain and Ireland.
