The International Wader Study Group requests help studying a shore bird called the sanderling

September 8th, 2011 by Glyn Young

The International Wader Study Group is asking birdwatchers and interested people to help with a study of sanderlings, Calidris alba.

A sanderling, Calidris alba, looks for food on the lower shore of Vazon, west coast of Guernsey (click image to expand - ©RLLord)

Anyone visiting beaches or other intertidal areas can help the International Wader Study Group with their research.

If you observe sanderlings, please report the following:

  • Date
  • Location
  • Time
  • Number of sanderlings

It would be especially helpful if you were able to report also:

  • The number of colour-ringed individuals you observe (the absence of colour-ringed birds is useful information too.)
  • The colour combination of the observed colour-ringed sanderlings. General help is available here on reporting bird re-sightings, and help is available here for reporting sanderling re-sightings.
  • The number of birds that you checked (one by one) for colour-rings (usually less than the total birds counted because it is often difficult to inspect the legs for rings of all sanderlings present)
  • The number of adult and juvenile birds. How to discriminate adults and juveniles in the field is explained here.
  • Any information about behaviour (how many birds were doing what?)

To help identify and count the sanderlings use a pair of binoculars, or a telescope with zoom objective, and bring a notebook and pencil or pen to record the information.
