OK, so I might not be seeing be seeing many wingbars or “megas” at the moment but one of the joys of birding is that the idea of rarity is a relative thing. A rare bird in Norway will be a common bird somewhere else and what gets us excited all depends on the geographical boundaries we are operating in. So, a Cape May Warbler will be common in certain parts of the US (although apparently not in Cape May where it really is a mega) whilst it causes people to travel overnight in Norway.
The Azores islands are in the middle of the Atlantic and could
equally be included in the Americas or Western Palearctic. They have ended up
being included in WP and this drives many European birders to travel there
every autumn to see the American birds that regularly turn up. It would be
cheaper and easier to travel to the east coast of the USA and see the same
birds but then they wouldn’t have the same relative rarity value that is all
decided by the geographical area one has chosen. Those who have a local patch
can get very excited about birds that are just common a few kilometers
away - I for example would throw a party
if I saw a House Sparrow in Maridalen but wouldn’t bat an eye lid if I saw one
in my garden just 5 minutes drive away.
Today, I had one of those relative days. Whilst bemoaning
that I am stuck in Oslo and closely following the antics of people on Værøy,
Røst or Utsira there is always something to find out there. A dog and family
walk in Maridalen started off very quietly. It was a wonderful autumn day with
no wind and great colours on the trees but there were hardly any birds either.
As we sat down for some refueling I heard what I was sure was a Grey-headed
Woodpecker calling from the otherside of a bay on the lake. This is a species I
see barely annually (although occurs over most of Norway) and have seen just
twice before in Maridalen so this was a big thing. After a bit of waiting and
some encouragement if flew across the bay and landed in the trees behind where
we were sitting and carried on calling. Mrs. OB and Jr Jr couldn’t quite work
out was the fuss was about but I filled my boots for as long as it lasted.
Another interesting sighting was of an injured juvenile
Whooper Swan on the lake. This will be missing youngster who clearly isn’t dead
as I assumed but its drooping wings testify that it cannot fly and has been abandoned
by the family. I have no idea what has caused the injury but my best guess
would be flying into the wires over the bridge at Dausjøelva which one of its
parents also did last spring. It is perhaps surprising that they have already
abandoned one of their young but the ability to fly is key for a migratory
species that will head south in a few weeks. Many large species lay few eggs
and put a lot of effort into raising maybe only one youngster every other year
but the fact that Whooper Swans lay 8 eggs suggests that they expect to lose
many along the way.

Nice one Rixy!
ReplyDeleteI've always regarded GH Woodpecker as something of a migrant and your record fits right in. Although they are said to not cross water I see them on an offshore island quite regularly and there is a definite peak in records out where I live in late(ish) autumn. Although the species breeds in small numbers locally they turn up all over the place in autumn - without doubt birds from elsewhere - I have also seen them on direct migration both at the coast and in the mountains.....
There is some (albeit now a little outdated) info about this here:

I agree with you Jules. I have had one on Værøy and have just posted on Twitter that I wouldn't write off the chances of the species turning up in the UK
ReplyDeleteI thoroughly agree about the Azores and I finally added House Sparrow to my BRU patch list this year - you should have seen me running as if I'd just found a Tennessee Warbler! Had a nice few days lately with a Yellow-browed Warbler which returned to my neighbouring park almost one year after I last found it. Ste
