1000 Up!

Almost two years have passed since we started our colour ringing project on north west Coot, today we colour marked our 1000th bird! This milestone total saw the end of us using individual colour ring combinations, to see the start of using individual coded darvic rings!

On 29/10/2009 when we had hundreds and hundreds of colour ring combinations to use up, it felt as though it would take us an age to reach our target goal! However, I’m rather surprised to be writing this today – that 1000 hand captured Coot have now been colour ringed!!

I won’t go into great detail on this, as we’re just about to analyse what we’ve already gathered. However of the 1000 colour ringed birds, 540 have subsequently been sighted again and 202 of these away from their ringing locations, with many birds being sighted at more than one location.

The updated sightings map, looking rather hectic! Red = ringed at Southport, Green = Crompton Lodges, Blue = Redesmere, Purple = Westport Lake. Many more sightings are on here, however they’re hidden by already placed markers.

The milestone also represents bringing on board other ringers throughout the UK, who will be colour marking birds as part of the project. This includes ringers in Newcastle, Shropshire, Norfolk & North Wales and possibly ringers in Cornwall, London, Derbyshire and Cumbria. Together with Radipole Ringing Groups current marking programmes in Dorset & Devon – we’re hoping to colour mark birds on a broader scale across the UK.

Our new colour ringing scheme uses white darvic rings, with black alpha numeric codes, on the left leg – with a BTO ring on the right leg. Letters used are – A, B, C, D, F, H, I, J, L, N, R, S, T, V, X & Z. Numbers used – 3, 4, 6 & 7.

Please report sightings of ALL colour marked Coot to me at kanebrides(add)gmail.com – it is very important to carry on sending in sightings of the individual colour ring combinations – as these will add further to the information that we’ve already got on these birds.

If anyone is sitting on any sightings and have still yet to report them – I’d be particularly grateful if you could send these to me (at the above address) so that we can use these sightings in the analysis.
