Yesterday morning I successfully ignored the IKEA flat pack
furniture that needed un-flatting and went up into Maridalen. With no wind and
sun I had high hopes of seeing soaring raptors (and finally a Honey Buzzard)
and butterflies. This year has been poor for both of these groups but a day
like today should be as good as any for them.
Raptors were really hard work and apart from a single
hunting Sparrowhawk I had to wait 5!! hours before I finally (and a long time
after I had intended to return to the un-flatting) found some soaring raptors
when I had a group of three Common Buzzards. These were followed by another
Common Buzzard a little later but that was to be it. I have a feeling that
something has happened with the larger raptors around Maridalen this year –
hopefully it is just a bad breeding season rather than something more sinister.
I fared a better with butterflies. There were not large numbers
except for the whites (which I still struggle with) but I ended up with quite a
lot of variety although had no blues or hairstreaks. Here are the 15 species I
saw:
Queen of Spain Fritillary (solvkåpe)
Silver Washed Fritillary (keiserkåpe)
Lesser Marbled Fritillary (engperlemorvinge)
Dark Green Fritillary (aglajaperlemorvinge)
Red Admiral (admiral)
Small Tortoisehell (neslesommerfugl)
Peacock (dagpåfuglsommerfugl)
Painted Lady (tistelsommerfugl)
Comma (Hvit C)
Ringlet (gullringvinge)
Scare Copper (oransjegullvinge)
Brimstone (sitronsommerfugl)
Green veined White (rapssommerfugl)
Large White (stor kålsommerfugl)
Small White (liten kålsommerfugl)
Queen of Spain Fritillaries seem to have established
themselves in Maridalen after an individual I saw last year was the very first
to be reported from Oslo in ArtsObservasjoner and I had up to 4 together
including mating. I find that this species can vary a lot in size and also in
colour on the upperwing and I spent lots of time trying to see the underwing of
fritillary butterflies only to be “disappointed” to see the silver spots of
this species. I do suspect though that I had at least one other species of
fritillary (medium large) in addition to the ones I have recorded.
The copper butterflies were interesting. I was sure that I
had seen a couple Small Coppers (ildgullvinge) but the pictures I took show
(based on the underwing) that they were actually female Scarce Coppers
(oransjegullvinge) of which I also saw the very distinctive males.
I tried my luck with dragonflies and damselflies and
identified 3 species of dragonfly – Black Dater (svart høstlibelle), Four-spotted
Chaser (firflekklibelle) and Brown Hawker (brun øyenstikker) - and one of
damselfly - Common Blue Damselfly (stor blåvannymfe) although there were other
species that I never managed to photograph of dragonfly that I didn’t manage to
photo (ID in front of the computer is as far as I have come with these species
groups). Black Darter remains by far the commonest species with thousands of
them and I only saw a handful of large dragons.
What about the non-raptor birds though? On the lake there
was an adult and two juvenile Arctic Terns one of which was begging for food. I
had a couple of juv Red-backed Shrikes and 2 very fresh and presumably juvenile
Marsh Warblers where a male had been singing in the late spring strongly suggesting
successful local breeding. The Whooper Swan family is still going strong and I
found the remains of the missing youngster although couldn’t make out how it
had died. I also had a pair of Cranes and I reckon this species will attempt to
nest in not too many years.
More signs of migration were my first returning Meadow
Pipits.
I took a ridiculous numbers of photos. Here is jut a selection.
