BIRD GUIDING AROUND OSLO

Crests

I have, as expected, visited Fornebu both yesterday and today. Yesterday I failed to find the Firecrest (and it was not reported by any of the other people looking) but today I found it after much perseverance (and after others had given up).  Snow fell on Wednesday night and this has caused the bird to change its behaviour once again to feeding very low down in the bushes or on the ground. It seems strange that it finds more food on the snow that higher up in the pines (where it fed in the sun on Tuesday and Wednesday) but that would definitely seem to be the case. It was once again feeding on its own although there were a couple of Goldcrests, Treecreeper and Blue Tit in the area. One of the Goldcrests fed at eye level less than 3 metres away and gave me my closest ever views of the species – if only the Firecrest had been that cooperative!

Water Rails and Bearded Tits were still present and I managed some pictures of Beardies for the first time in a couple of weeks. They were feeding on the ground at the edge of the reedbed and at times they would disappear in holes under the snow and fallen reeds.


Despite being quite cloe all the branches made photos of the Firecrest (rødtoppfuglekonge) very difficult and meant I had to use manual focus. In these conditions a bird in habitat photo is always a good option ;-)

Treecreeper and Firecrest

Yesterday offered blue skies and sun and I hoped a chance to enjoy the Firecrest in good light. I was clearly not alone in that thought and when I arrived the bird had already been seen which at least meant that I didn’t need to spend too much time searching for it. The bird eventually showed very well and was feeding high up in some small pine trees and calling frequently which was very different behaviour to my previous observations. I believe that this difference in behaviour was driven by the sunlight which was making small insects easier to find in the pines. It was in constant movement and could be frequently seen grabbing microscopic food items. It moved around quite a lot and at one stage was together with a Goldcrest. These two birds were chasing each other around although I couldn’t work out who was the chaser and who was the chase.

The bird made a variety of calls today but only on a couple of occasions did I hear the characteristic call which attracted me to the bird when I found it last week. Otherwise it was making calls very similar to Goldcrest and also Treecreeper. Indeed, it was in the same vicinity as a Treecreeper for a while and I found it difficult to separating the quite contact calls of both birds.

I'm on Fire

As usual my weekend was not spent birding but it looks like a number of people were out at Fornebu looking the Firecrest but there were no reports of it after Thursday afternoon. This was just the sort of motivation I needed to visit Fornebu today J It took quite a bit of work but eventually I found him about 400m away from where he was on Wednesday and Thursday. He was all alone and feeding mostly on the floor. There were a couple of Goldcrests not too far away and these were feeding 3-4 metres up in bushes and calling quite a lot whereas their cousin made very little noise. He was quite confiding but there were far too many twigs in the way to get any decent pictures and I had to use manual focus all the time.

Bearded Tits were calling in two of the reedbeds and there were four calling Water Rails in total one of which showed itself on two occasions. A calling Chiffchaff from a reedbed was quite a surprise but if a Firecrest can survive then a Chiffchaff should also manage to.

Back at home there was a mini influx of House Sparrows into the garden after they had been mostly absent for a few weeks. One bird caught my attention and after a bit of study I have concluded that it is a female hybrid between House and Tree Sparrow. I have seen a fair few pictures of this hybrid combo before, but these are always of assumed males whereas this bird was clearly a female due to a yellow bill base and pale supercilium (features of female House Sparrow) and a quick google search has yet to reveal any other photos of females. It was quite a subtle bird which mostly resembled a female House Sparrow but had a prominent white collar, a black smudge on a white chin, a small grey bib and a crown that was a mixture of grey and brown.

Firecrest video

The firecrest was still present today and had a number of admirers but was much more difficult to observe than when I found it yesterday and it hardly made any noise. There were also two Goldcrests in the area which made things a bit more complicated. It was feeding exclusively on the ground during the 25 minutes that I saw the bird but then vanished for a couple of hours before being found again later. For an insect eating bird of more southerly climes it must be a challenge to stay alive!

Now we are talking!

I decided to shake things up a but today and be a bit rebellious – I visited Fornebu first and Maridalen afterwards!! I know, I know, I live life on the edge ;-)

Overnight wet snow had left the reedbeds partially flattened but this did nothing to make the Bearded Tits more visible although I was eventually able to ascertain that there were still at least two in Holtekilen and four in Storøykilen. I then decided to go out to Koksa which I haven’t done so much recently as there has been so little there. As I walked out I reminisced over the rare birds that I have seen at Fornebu over the years with two Isabelline Shrikes, a Siberian Stonechat, a Med Gull and Sabine’s Gull heading my list. I mulled over the fact that the chances of finding anything rare was getting less and less with the continued development of the site and it may be that Bearded Tits become the rarest species that the site hosts with any regularity.

When I arrived at Koksa a complete lack of life was confirmation of what my previous visits have told me. As I walked along hoping that maybe a Water Rail would call I heard a high-pitched call from the small copse by the path. There is often Treecreeper here but the call didn’t quite match and I had a feeling that it was something much rarer. I pulled out my phone and checked the call of Firecrest and got an instant match! This species has recently turned up in record numbers in Sweden, 7 have been seen in one area of Rogaland in west Norway and it looks like the UK has had very high numbers. I have had it on my mind for the last month and have always checked out Goldcrests when  I have encountered them away from the deep forests but was not planning on finding one today! But was it really one? It continued calling and I walked towards it without seeing anything and started to check the tree trunks for Treecreeper when I finally saw a small bird in a bush. Bins up and bang – Akershus County’s first Firecrest was a fact (following Oslo’s first record in May). This species was removed from the national rarity list this year due to a significant increase in records but they have been centred on the southern and south west coast.

I took a while to get any decent shots of the bird and melting snow from the branches above me kept falling on me and my optics, but I was happy with what I managed given the light and conditions. I didn’t get to spend much time with it as a message from my eldest meant I had to go and help her with something, but I got the news out and it was seen again later in the day.

Maridalen did get a visit later in the afternoon where a flock of 140 Yellowhammers is the largest flock recorded in Maridalen. I did not get to see them well but there must be a chance of finding a Pine Bunting amongst them…


It is fair to say that my case of birder blues has been (at least temporarily) banished!





the first picture I fired off - just what a record shot should look like!

the thin orane stripe within the yellow crown shows this to be a male and I believe a 1cy bird as an older bird should have an even more orange crown

food was clearly not east to come by for an insect eater in the snow but I was surprised to see it on the ground

Routines

I have said that there are few (if any) new birds to see at the moment but my current birding is not exactly designed to find anything new. I seem to be visiting the same locations all the time and seeing the same birds but the problem is that they are nice birds and I am always hoping to see and document some interesting behaviour. It is the Bearded Tits at Fornebu and Pygmy Owls in Maridalen that have captured my attention.

Both these are getting more and more difficult to find but I see it as a badge of honour to be able to find them when others fail, and it of course is good for guiding if I know where they are. The Pygmy Owls in Maridalen are clearly not settled anymore and this is because there is not a high density of rodents for them to find so they need to move around. Yesterday I found a single bird atop a spruce in the forest where he was being scolded by Coal Tits and a Great Spotted Woodpecker and he also sang a bit. I didn’t observe him hunting though which is the behaviour that I want to document.
Otherwise Maridalen was quiet and the lake is now 50% frozen.


At Fornebu the shallow salt water bays have been frozen for a long time and there is snow on the floor of the reedbeds, but this doesn’t stop the Bearded Tits spending almost all their time searching for food on the ground. They are very difficult to find because they also call very infrequently and if they do call it is normally a very weak contact call. Yesterday though I was very lucky though as a group of three birds were feeding right by the path and I was able to observe and document them over a long period. I had them high up feeding on the seed heads for about a minute but the rest of the time they were running around like mice on the ground feeding and for the first time I was able to properly observe this behaviour. There seemed to be very little food for them to find compared to when they were up on the seed heads so one must wonder why they choose to feed on the ground. My theory is that it is to avoid predation. When they are high up they must be easy targets for Sparrowhawks which could also explain why the number of birds always decreases as the autumn/winter progresses. So, they face a trade-off between easy to find food and the risk of predation.
