Before I recount the very successful and enjoyable weekend in Valdres I have a dirty little twitch to confess to. Whilst we were away Anders found a Citrine Wagtail at Årnestangen and with it still being present yesterday I had to go for it today. This would be an Akershus County tick for me and there have only been two previous records in Akershus plus one in Oslo, all being spring males.
As I arrived at the field where it was reported yesterday I
immediately heard a simple wagtail song that very much resembled the song of
thunbergi Yellow Wagtail but was perhaps a tad more zingy. It took a long time
to locate the bird but I eventually found him (because a singing wagtail has to
be a male?) on the ground in the middle of a field that had only recently been
ploughed and sown (and in the process taken out at least one Lapwing nest). Only
problem was that the plumage was very female like and in fact the only plumage
element suggesting male (to me) were the black(ish) “shoulders”. My reading of
the literature is that even a 1st summer male Citrine Wagtail should have a
more developed plumage although I think the only explanation for this birds
plumage is that it is a 1st summer male.
It spent nearly all of its time on the ground in the middle
of the field and one reason may have been that a male thunbergi Yellow Wagtail
was singing from bushes on the edge of the field. At one point though it did
fly up into the same bushes and I had both birds singing close to each other
(and close to me). The songs were very similar and I duly decided to record
them although I have since discovered that in familiar style I failed to press
the record button….
here I got very close to it when it sang from a bush but I was always below and in front so my pictures do not show any of the "interesting" bits |
the male thunbergi (Grey-headed) Yellow Wagtail that sang nearby. This bird has a slight white supercilium perhaps suggesting some other subspecific genes in its heritage |
