New Twite Colour Combinations

Hopefully, Twite will begin arriving on passage at Heysham Harbour very soon.  Colour ringing that has been undertaken here since 2002 will be continuing.  From now onwards however, a new scheme of site colour plus numbered colour rings will be utilised such that each bird will be uniquely identified.
 

The combination for this winter will be:  Right Leg below tarsal joint – Pale Blue over BTO Metal,  Left Leg below tarsal joint – White with dark engraved number between 1 and 99.

Sightings where the colours only are recorded will be attributable to Site and Season, but individual birds will be identifiable too if the numbers can be read (by telescope, digital camera etc) so I urge everyone to keep their eyes open for Twite wearing colour rings and report any combinations, and hopefully engraved numbers to Alan Draper.

All sightings will of course be eagerly awaited whether or not the colour ring numbers are known.  There will also hopefully be birds wearing the colour combinations from previous seasons (Right Leg: BTO Metal,  Left Leg: Pale Blue over a two-colour striped ring) and sightings of any of these are also very welcome.

Thank you in advance.
