New Rings

Dutch bird ringer Frank Majoor is now using a new set of color rings for ringing Black-headed Gulls in The Netherlands: a white ring with two characters separated by a dash (-).

Black-headed Gull, >1cy, W[H-E]

These have been introduced in November this year, after having run out of the usual red rings which have been used between 2004 and 2010.

The color rings are placed on the left leg (tarsus) and should be read upwards. A metal ring is placed on the right leg (tarsus, ringing station ‘Vogeltrekstation Arnhem’).

Used codes are:

  • A-A to A-Z
  • 0-0 to 9-9
  • A-1 to Z-9
  • 1-A to 9-Z

More information can be found on Frank’s website (scroll down to ‘codes which have been used’).
Details for sending in observations can be found on www.cr-birding.org.
