Here is a request for birders to make an effort to read the 3-character "field-readable" codes on the bands of any terns they come across - but especially Roseate Terns:
Researchers really would like to know the identities and ages of the individuals that are being seen at that time of year that far away from the breeding colony sites at Falkner Island and Great Gull Island. Research on Cape Cod suggests that there are many more young nonbreeding 2- and 3-year-olds than we once suspected that are coming back to North America each year that are either not visiting at all, or only spending a little time at the colony sites.
Also, this past winter researchers had Pedro Lima put about 500 yellow field readable tags on ROSTs wintering in Brazil and would like to know how many of them show up in North America this year.
