Winter Atlas Survey: 2007/8 to 2010/11
 

Fieldworkers in Co Waterford are contributing to this national survey (throughout Ireland and Britain) to map the distribution and relative abundance of wintering birds throughout these islands.  Although results of the national atlas will be presented at 10-km scale (10-km x 10-km squares), much of the fieldwork will be done at a finer scale - collecting records within 2-km x 2-km tetrads.  To take part, click Bird Atlas 2007-2011 (www.birdatlas.net) - see also the BirdWatch Ireland website for details of Irish coverage.  See also a list of frequently-asked questions.   Preliminary coverage & species maps are given below.  Latest update 2 March 2010.

Unlike the Waterford Breeding Bird Atlas (full details here), winter atlas coverage in Waterford will probably not be complete, i.e. only a sample of 2-km tetrads will be surveyed fully.  (The basic requirement is 8 or more tetrads per 10-km square, or fewer in some coastal squares.)  Full coverage of a tetrads involves the Timed Tetrad Visit (TTV) method, i.e. two 1-hour counts, one during November-December and one January-February.  However, less-intensive coverage of other tetrads, using the Roving Records (RR) method, will provide further information.  If the coverage achieved by a combination of these methods is good enough, it may be possible to produce detailed maps of winter bird distribution for Waterford. 

 

Two full seasons of winter coverage has been completed so far (1 Nov 2007 to 29 Feb 2008 & 2009), and the maps here show coverage to date and provisional numbers of species recorded, excluding records yet to be submitted or compiled.  If you can help fill the gaps this winter or next, either by doing Timed Tetrad Visits (especially for more experienced observers) or collecting Roving Records, or both, please get in touch - either via the Bird Atlas 2007-2011 website or email the Waterford organiser, Paul Walsh.

Winter coverage update:  tetrads already allocated or covered

waterford_winterallocated_02032010.gif
Update @ 12/02/2010

The map above shows the tetrads for which volunteer counters have already 'signed up' for (or completed) Timed Tetrad Visits.  We need to cover at least 8 tetrads in each main square, or all the eligible tetrads in any coastal squares that have fewer than 8 tetrads.  'Eligible' tetrads are those that have their midpoint either on dry land or above Low Water Mark.  So far, 186 specific tetrads (34% of county total) have been allocated for TTV coverage, and at least 156 tetrads (29% of county total) have had 1 or 2 hour's winter coverage since November 2007. 

 

As well as Timed Tetrad Visits, volunteers are also needed to collect Roving Records - either in specific tetrads (e.g. near home) or from any tetrads throughout the county.  This will help build up fuller species lists for each tetrad and 10-km square.  See Bird Atlas 2007-2011, or email, to sign up.

Species richness by 10-km square
 
The map below (from national atlas website) summarises coverage since 1/11/2007 as as % of the species totals recorded in the previous Winter Atlas (1981/82 to 1983/84).  Redover 90% of previous total;  orange = 75-90%yellow = 50-74%white = 1-50%

Example distribution maps
 
The maps below (from the national atlas website) show distribution maps for a range of species that are indicative of coverage in different habitats, for the 10-km squares that are wholly or mainly within Co Waterford.   Blackbird for instance is a good indicator of coverage in towns, gardens, woodland and farmland.  
.
 
Dots indicate presence in a tetrad.  (A grey square in the background indicates records not attributed to a particular tetrad.)  Note that the maps are preliminary and don't include records yet to be received on paper forms, only those submitted online so far.  Moreover, many BirdTrack distribution records have yet to be converted to tetrad scale dots.
