Between 1990 and 2002 we trapped and ringed 1,158 birds. Additionally from spring 2000 until spring 2002 they
were colour ringed with
combinations as follows:
Left leg: 2 colours. Right leg: Metal ring over 2
Colours that were used are red, yellow, lime green, white,
It is unlikely that any of
these birds are alive now as it is 31 years since the study ended.
This 12 year study showed that birds on passage in March are
predominately the nominate race O.o.oenanthe. Greenland race
wheatears O .o.leucorrhoa begin to arrive in mid April and then the ratio of
Greenland:nominate is approximately 50:50.
In May, Greenland wheatears predominate and
outnumber the nominate race.
The ultimate destinations of these Greenland race birds,
whether it is Greenland or Iceland is not known as there have been no
recoveries from the breeding grounds!
An analysis of wing lengths and weights of Wheatears
Oenanthe oenanthe caught on the north west Norfolk
coast in spring to determine the incidence and timing of the Greenland race
between 1990 - 1996 was undertaken and a Pdf file can be downloaded
