Marked BTG's.

Black-tailed Godwit. Bob Bushell @ BNFOD 


I've been finding excellent numbers of Black-tailed Godwit on the Lune Estuary recently, amongst which I found two marked birds at Cockersands and was more than a little pleased to learn I had seen one of them on two previous occasions. Come July this Black-tailed Godwit will be four years old and will have returned to Iceland probably three times since it was ringed there in 2012, but certainly has twice as the history below shows.

Ringed as a chick 6 July 2012 at Ytri Lambadalur, Dyrafjordur, NW Iceland

This bird is an amazing 20 years old, but a 25 year old Black-tailed Godwit holds the longevity record soon to become 26 years.

The history for this bird is a lengthy one, so I have omitted multi sightings made in any one month at the same location to make reading easier. The bird has been most seen on the Dee Estuary in Cheshire, but has also been located at Leighton Moss RSPB Reserve in Lancashire four times in four years. The bird wasn't re-sighted for 4 years 2001-2005, it went the longest distance twice in 2000 and 2001 to Cley in Norfolk where it's marks were read by an amazing coincidence on the very same date of 22 February in both years.

The people who attended to these two records of colour marked BTG's for me are aware of my appreciation and thanks for the histories they sent me.

Thanks also to Bob for his excellent image of the BTG, every bit as stunning as some of my of birds at Cockersands.

Yes Martin....It is the very bird in this post (LR-Y//W) which I saw at Cockersands 26 February, and as you say was seen at Newton Marsh 11 March, it is indeed 20 years old.

Theres a good chance you will bump into me in the Trough and I hope you do.
