Less Beans
Yesterday saw lovely blue skies, no wind, dry air and
temperatures just below zero whilst today was cloudy, misty, rainy and
temperatures were hovering just above zero. Neither day did much to encourage
migration but yesterday’s un and todays rain has caused the thaw to start
although temperatures are forecast to fall below -10C next week so we will
still have to be patient in our wait for spring.
Yesterday I returned to the Glomma River. Only 55 Taiga Beans
were now present, and I would not be surprised if the other 23 from yesterday
have returned to Denmark. There were now lots of droppings on the ice which
were absent yesterday and help confirm that the birds did arrive yesterday
morning. The geese were frequently up on the ice picking at something – whatever
it was too small for me to see and I wonder if they were eating insects. Whatever
it is they will surely lose weight until they can start feeding on the fields
which may be in over a week?
I visited other sites on the river and found
Slavonian Grebes, Long-tailed Duck and Scaup along with my first two migrating
Wigeon of the year but there was no viz mig to witness.
In the evening Per Christian and I went owling. It
was perfect conditions in that it was windless and with temperatures “only”
dropping to -4C it was actually quite comfortable to be out. We had a very good
start with 5 singing Tengmalm’s Owls in the first 2-3 kilometres but then after
this we had nothing. I had hoped to be able to get some good photos of a Tengmalm’s
but despite our best efforts we only observed one in flight in the light of our
torches and never managed to see it perched.
Today I visited Bygdøy and Fornebu where Greylag
numbers are slowly building up and a flock of 22 was on a snow-covered field
feeding under a large tree where the snow had melted. Small flocks of Starlings
at both sites were the only real sign of passerine migration and a couple of
birds were singing and mimicking other birds including Redwing which did
suddenly transport me into the spring until they flew off and I abruptly returned
to winter.
the sun was shining on the ice. The Taiga Beans can be seen on the ice
there were only 3 ringed birds. One had a neck collar : 7U who I first saw here in March 2014. One had a green leg ring having lost it GPS collar and can be identified as 10 who I also first saw here in March 2014. The third bird only has a metal leg ring having lost its neck collar and unfortunately cannot be identified.
what are they picking at?
"7U" can just about be seen in this picture
here is the single Pink-footed Goose (kortnebbgås) that is together with the Beans and which acted as those it maybe paired with one of the Beans
Whooper Swas (sangsvane)
three Slavonian Grebes (horndykker)
Greylag Geese that have found the only snow free ground at Bygdøy
