Finally I managed some birding with a couple of hours at Årnestangen on friday and was rewarded with a norwegian tick in the form of a Red Throated Pipit. No great veiws unfortunately just a flushed bird calling but the call is distinctive enough.
Unfortunately the water levels have risen very quickly lately so there was only a tiny amount of mud left which held just a single Dunlin and 2 Ringed Plover (a couple of days earlier there had over 100 waders of many species).
A late Cuckoo was the closest I came to a raptor and my first Great Grey Shrike of the autumn was nice. There were many hundred wildfowl and swans but as is often the case they were very distant and difficult to identify to species. 400+ Cormorants were feeding close in though in a fast moving flock that was obviously chasing a shoal of fish.
A very large caterpillar feeding on vegetation in a field was I presume a Swallowtail Butterly.
