Østfold birding


Yesterday saw me teaming up with Jules again and we headed for Østfold. We arrived at Kurefjorden at 0840 and had acceptable light although it soon deteriorated as the sun shone strongly. There was a good selection of waders which even included a genuine Black-tailed Godwit (svarthalespove). Present for a few days now this bird was feeding on its own when we arrived but later joined a couple of Bar-tailed Godwits (lappspove). Little Stint (dvergsnipe), Curlew Sandpiper (tundrasnipe), Turnstone (steinvender) and Spotted Redshank (sotsnipe) contributed to a good selection of waders with Ruff (brushane) being the most numerous with around 70 individuals.

We spent some time scanning the edge of some reeds and this turned up trumps with a Water Rail (vannrikse), 3 Bluethroats (blåstrupe) and a few Reed Warblers (rørsanger) and White Wagtails (linerle) appearing from out of the reeds. The Water Rail was very aggressive towards the Bluethroats although it was unclear as to whether it may have been trying to catch them. We also had single Marsh Warbler (myrsanger) and Red-backed Shrike (tornskate).

Raptors were not so obvious but we did have a Hobby (lerkefalk) which was plucking a swallow and eating in flight.

After scanning for raptors from Burum which gave a few Sparrowhawks (spurvehauk) and Buzzards (musvåk) with the Sparrowhawks at least looking to be migrating I made a decision that surprises me but for which I am glad – to visit Øra (Jules hadn’t seen the Trumpeterfinch). When we arrived and opened the doors to a rather strong smell of cr*p I immediately regretted my decision but I breathed in, put a clothes peg on my nose and stepped out. Our initial target was the Trumpeter Finch (trompeterfink) which luckily fell within the space of 15 minutes. Another birder had just found it and it was feeding right by the side of a path on its own. The other birder had found it right under his feet and when we walked up to him it was less than 5 metres away. It was half hidden in some rocks though which made it a slight challenge to photograph.

Satisfied with our views we then set about finding some of the Red-throated Pipits (lappiplerke) that have been reported here the last couple of days. After seeing and hearing only Meadow Pipits (heipiplerke) we began to be a little doubtful but then suddenly a Red-throated Pipit flew over calling. Frustratingly it landed a long way off. We then scared another up but this one also landed in an area we couldn’t access. Things then began to go our way as the birds returned calling and eventually landed so they could be viewed. We had three birds together and they were holding themselves separately from the Meadow Pipits. These birds gave me my best views of autumn Red-throated Pipits (although the views were only brief and not too close) and I have to say that without the call they are by no means an easy bird to ID. The white “braces” on the back were not very noticeable and I did not get to see the streaked rump. I was reminded of the sentence in the Macmillan Field Guide to Bird Identification where they write “Records of non-calling individuals are likely to be very critically scrutinised by the BBRC”. Luckily though they did call frequently in flight.

Three birds here. The bird on the left is showing the white tram lines on the back but they are not that obvious
Øra also delivered a number of other good birds in the form of Bearded Tit (skjeggmeis), Peregrine (vandrefalk) and Marsh Harrier (sivhauk).

Øra did through up some unidentified birds aswell .Whilst watching the pipits we also heard (and saw as a silhouette) a bird that sounded good for Citrine Wagtail (sitronerle) but it never landed or allowed any plumage characters to be seen.

Some adult Lesser Black-backed Gulls (sildemåke) looked very black on the wings, long-winged and slender and immediately had me thinking of the fuscus race. There was also a juvenile bird with them that was very white and black and far more matched what a fuscus should look like rather than the local intermedius. Too far away for any good pictures they will have to go just go down as interesting birds.

Final interesting unidentified bird was a female duck that had the form and behaviour of a Wigeon (brunnakke) but the plumage of a Teal (krikkand). It associated with Mallards (stokkand) and Shoveler (skjeand) rather than the 400 Teal that were on sight and size wise seemed too large for Teal (it was noticeably smaller than Mallard but we never saw it next to another Teal for a direct comparison). We will never know what it was but I could easily imagine that it was a hybrid possibly Teal x Wigeon.

Photos from Nordland


Here are a selection of photos from around Bodø and Værøy.
11:55pm looking north from Værøy- the sun shines strongly

midnight. The sun sets (real midnight sun is restricted to a few days at the end of June at this latitude)


First some of the different Lesser Black-backed Gulls (sildemåke). First off, the fuscus from Valnes, notice the dark wings without any real border to the black wing tips.

presumed fuscus Lesser Black-backed Gull - notice how the light can change the appearance of the upperparts


Some from Værøy:
A fairly easy graellsii

An obvious graellsii in the middle with a Herring Gull (gråmåke) on the right and a darker LBBG on the left which I take to be an intermedius.

A difficult bird which could be dark graellsii or pale intermedius.

Another difficult bird which was quite small and cute so probably a female. The flight shot shows significant contract between the wing and wing tips so this is a graellsii I reckon. Also the photo was taken at 10pm so the grey back probably looked darker than it would have looked in the middle of the day.




I’ve read that the intermedius types in northern Norway might be the result of hybridisation between fuscus and graellsii. I don’t know about this but I can say that LBBG’s come in the whole range of colours up here. I also saw one dark graellsii type seemingly paired with a Herring Gull which could result in some even more difficult looking offspring.
EDIT: of course I had not considered the possibility of HEUGLINI when I wrote the original entry. I don't believe there are proven records of this sub-species in Norway but it is probably just as likely at this latitude and longitude as Graellssi

Some other pictures:

Also some scenic botanical shots from Værøy




A pale Whimbrel (småspove) – Slender-billed Curlew look alike


A group of five young Pintails (stjertand)
1k Pintails - the green on the wing of the right-hand bird shows it to be a males

The lack of green shows this bird to be a female

Tricky gulls

I see very few Lesser Black-backed Gulls (sildemåke) when I am in Northern Norway and there is a lot of uncertainty as to the sub-specific identity of many of the birds that occur here. One place where I do see birds is around Valnes to the south of Bodø. A few pairs appear to breed here amongst a loose colony of Herring (gråmåke) and Great Black-backed Gulls (svartbak). I have previously reported these as being fuscus (also called Baltic Gull) although I believe it is unclear as to whether fuscus still breed in Norway. I spent some time looking at the birds today and managed some half decent photos which i will upload later. For me these birds are fuscus. Plumage wise they are darker on the back than Great Black-backs, there is no discernible contrast between the black wing tips and rest of the wing, there is just one small white mirror on P10 and they have no discernible white tips to the outer primaries. Structure wise they are clearly smaller than Herring Gulls and appear long winged. The biggest clue for me though that they are fuscus is their behaviour. When feeding they fly like a small gull and swoop down and pick food off the water surface just like I have seen fuscus doing around Stockholm and in the Baltic. Both in size and behaviour they are also very unlike the intermedius that breed around Oslo. Also here Redstart (rødstjert) and Common Tern (makrellterne) but still no White-tailed Eagles (havørn) and the locals also say they have noticed far fewer eagles this year.
