Just of interest .... if you have any!
Just got the data from my group on some 2016 sightings of birds I ringed in Essex previously.
While (as you might expect) most of the colour ring sightings were relatively close by (SE England and the Channel coast), a few were noteworthy I think, and demonstrate how far, and relatively how quickly some birds travel - even birds under mature breeding age.
Two Herring gulls, ringed as 5 (second calendar year) in Dec 15
1. seen Batsfjord, Finnmark, Norway 2586km NNE in Jun 16
2. seen Helsingborg, Sweden 944km NE Apr16
It seems likely these were argentatus HG's, but ID-ing this in immatures is virtually impossible with certainty
An adult LBBG ringed Oct 15 seen Praia de Mira, Portugal 1387km SSE Nov16
Two BHG, both adult
1. ringed Oct 15, seen Hakalanniemi, Finland 1790km NE Jun 16
2. ringed Jan 16, seen Ojebyn, Sweden 1938km NNE Apr 16
I see a BHG (JJ03) that commutes annually between breeding near Oslo and Swanbourne Lake, near Arundel in West Sussex. Been doing it for at least 3 years.
Nothing earth-shattering here I know, but serves to demonstrate the 'internationality' requirement of bird conservation.
