Morgensol på himmelen

mandag 30. september 2019
af Henning Ettrup

Efter nogle dage med mørke skyer og til tider regnfulde morgener var solen atter fremme.

Vi er stadig mange på stationen – nu da der også er kommet gæster i lejligheden. Så vi delte os i et ringmærkerteam og observationshold. Yehonatan, og Laia startede tidligt med at åbne nettene, hvorefter Chris og Henning sluttede sig til ved Kabeltromlekrattet, ligesom Simon kom omkring et par gange. Laia fik sin første ringmærkning på stationen – en Fuglekonge. Koen og Judith tog sig af observationerne, mens der ikke blev mærket ved Jennes Sø.

Det blev en fin start på ringmærkningen, men efterhånden som solen kom højere på himmelen gik det helt i stå. Det blev til i alt 38 fugle – med Rødhals og Gransanger som hyppigste arter. Ingen overraskelser i dag. Eftermiddagen blev brugt til at klargøre 3 nye netbaner ved Kabeltromlekrattet.

Observatørerne havde ikke de store antal, men spredte observationer senere på dagen gav lidt forskellige fugle, bl.a. Lapværling, Stor Tornskade, Dværgmåge, Mosehornugle og Bjerglærke.

Om eftermiddagen skulle Chris, Laia og Judith absolut en tur i det 10 grader varme vand inden de skulle på tur med Simon og Køge Vinterbadeklub i Byfogedskoven inden dagen afsluttedes med en dejlig middag.

115 ringed birds in one morning

søndag 29. september 2019
af Judith Kloibhofer

We are many people at the station at the moment, so we can split up again. Yehonatan, Koen and I went to Jennes Sø to join Michael Ancher in ringing. Simon, Chris, Laia and Henning went to Kabeltromlekrattet to do the ringing there.

In Jennes Sø the ringing went very well. We had 66 birds, the most dominant species was Lesser Redpoll (Lille Gråsisken) with 44 individuals. Yehonatan was very happy about ringing his first Crested Tit (Topmejse). The observations between the rounds were also very good – we saw the Kingfisher (Isfugl) again, one Marsh Harrier (Rørhøg), some Goldfinches (Stillits), a flock of 60 Crossbill (Lille Korsnæb) crossing by and a Wood Mouse (Skovmus) trying to find some food in our backpacks. For Koen it was very interesting to study all the individuals of the redpolls as they show a big variety in the colouration.

The ringing group in Kabeltromlekrattet was joined by a 11-year old boy, Sander, from town. It was very exciting for him to see the ringing. After they catched a Barred Warbler (Høgesanger), more people came to the ringing side to watch the highlight. They were also very close to catch a Water rail (Vandriske) with the new trammelnets. So it seems like it is on the right place we just need some more luck. In total they caught 49 birds, which is a good number for Kabeltromlekrattet and the dominating species were Robins (Rødhals) and Blue Tits (Blåmejse).

Back at the station Yehonatan found a nice card from Rita on the table. She gave him regards for the New Year`s Eve that is in Israel today – Thanks Rita! We will celebrate it in the evening with some traditional apples with honey and wine ;).

In the afternoon Chris hold a presentation with the title “The birds of Svalbard”. There we got a nice insight in the most common and interesting bird species in the high arctic. Some of the species we can also see down here in Grenen in Autumn, like the Pink-footed Goose (Kortnæbbet Gås), the Arctic Terns (Havterne) and the Fulmars (Mallemuk). Another mentioned species was the Snow Bunting (Snespurv), which is kind of the “House Sparrow” of Svalbard. If you would like to here more about that species, you are welcome to join his next talk on the 25th of October at 19 o’clock.

Northern lights

lørdag 28. september 2019
af Chris Stolz

Friday night Yehonatan and I went night-catching at Grenen. Although it had rained quite a lot and puddles were on the beach, we didn’t meet any birds for the first hour. But despite that, two other observations were fascinating: First, when arriving at the waters edge, every single of our steps stimulated microscopic algae to exhibit bioluminescence, i.e. emittance of a greenish glow. The species is most likely Noctiluca scintillans, a planktonic dinoflagellate. We tried to take pictures or a video of this phenomena, but without a good camera our attempts were futile. I have tried many times to take pictures of northern lights with my mobile back in Tromsø, but the crappy phone-camera never managed to get them, which now was true regarding the mareel as well.

Shortly after, when I looked to the skies, my jaw dropped. There were actually northern lights visible! Not very strong, but clearly the moving bands of aurora borealis, which I have seen so many times further north. We were getting excited, even though the aurora had basically no colour whatsoever and it was only visible towards the northern part of the sky. We called back to the station and Michael and Koen went out to Grenen parking and managed to see it as well. Unfortunately, nobody took pictures – I’m sure that a good camera would have managed to catch some colour. Later, I looked up the solar activity and disturbance of the earth’s magnetosphere during the time of our observation. The Kp index, which is a way to measure the energy input of the solar wind hitting earth, was up to 5+ on Friday night, indicating a geomagnetic storm. Only at around this value the northern lights can be seen at Skagen, so we got really lucky with being out at that time and having clear skies. To be honest, I would have not guessed that I would see the northern lights once more this year.

After all the excitement due to the special light from below and above, we managed to catch a first year red knot (islandsk ryle) at the tip of Grenen, too!

The next morning, the observatory’s team split up in two groups to ring in both Jenne’s Sø and Kabeltrommelkrattet. Henning, Michael, Simon, Judith and I went to Kabeltrommelkrattet after the rain in the morning stopped and were happy to not get wet afterwards. The ringing itself was average, but in the meanwhile to hen harriers (blå kærhøg) and at least one calling penduline tit (pungmejse) were indeed fine birds to observe.

Michael, Yehonatan, Koen and Laia unfortunately got really wet at Jenne’s Sø and had to come back to the station to switch into dry clothes. After the rain stopped, they however got many birds into their nets – mainly lesser redpolls (lille gråsisken), which were attracted by their own calls played from speakers.

Laia also found some commom toads (skrubtudse), which she was really happy about.

On the afternoon, Rita came by and provided us with apples, pomegranate, honey and chocolate in anticipation of the the next day Jewish New Year celebration. Yehonatan told us that it is a tradition to eat fish heads on that day, but we will see if that is going to happen. Apples, pomegranate and honey seems to be the better (and also traditional) alternative.

The afternoon was dominated by indoor work – Laia, Yehonatan and Judith were working on our radar, while Koen and I developed the protocol for night recordings further. I also sat down to prepare my talk about Svalbards avifauna for the next day.

Lovely weather for ducks..

fredag 27. september 2019
af Michael Fink

Morgensobservationer og ringmærkning gik helt i vasken på grund af regn tilsat en kuling fra sydøst.

Tiden blev brugt på diverse indendørssysler indtil vinden ved frokosttid var aftaget til under 10 sekundmeter, og så var det ud.. Der var tydeligt flere småfugle i krattene og midt i regnen blev der fundet en Hvidbrynet Løvsanger i Ellekrattet nedenfor Klitbo, sammen med Fuglekonger, Broget og Grå Fluesnapper. Dagens regn medførte at strandsøen på ydersiden af klitten genopstod fra Nordstranden og helt ud mod Grenen.

No ducks in the trap

torsdag 26. september 2019
af Yehonatan ben aroia

After leaving the duck trap all night i woke up even earlier than usual and had to go and check the trap before going to ringing. in this time Michael and Koen went to open the up the nets at Kabeltroumell. I walked to the lake and saw that we didn’t had enough luck to catch a duck and went to the ringing area to also try the Quail nets that Simon recently got for the station. Also didn’t have luck with these…. Also the ringing was very slow with fewer birds than usual.

71333393 697966784046516 4825482747323613184 n

A nice second year Jernspurv. the very most of them that we catch are first year so far we only had 2-3 Adult birds in this Autumn


After the very long morning for me, going from place to place and doing a lot of stuff we came back to the station and had a power nap so we will be fresh for cleaning. We had a very quick cleaning day, very nice to have 6 people cleaning around and it is also much faster.

After the cleaning we got a call that someone found a kingfisher pretty close to station so we maybe will go and try to ring it, but we all were too busy and didn’t had enough time for that today, maybe if he will stay for tomorrow….

After that we all had a nice time together having dinner and usual routine in the station.

We also received a nice text that our neighbors wrote about the week they had here and what they have experienced living in the station for a week so u we can share it.

Trip to Saltum Strand

onsdag 25. september 2019
af Judith Kloibhofer

Today our team was split up. Koen and Michael went out for observations at worlds end 3 for doing some seawatching. The highlights were a flock of pink-footed geese (kortnæbbet gås) and one lapland bunting (lapværling) flying over. Koen was also impressed by all the common scoter (sortand) and velvet scoters (fløjsand) were nice, as he is not used to see so many of them and Michael saw a juvenile common tern (fjordterne) roosting on the beach. After two hours Koen went to Ellekrattet to continue the observations there, as the wind and the sand was very annoying today. On the way he heard a yellow-browed warbler (hvidbrynet løvsanger) calling! At Ellekrattet the counting included two tree pipits. After the observations they went back to the station and had some lunch and a powernap.

The other part of our team (Simon, Chris, Yehonatan, Laia, Judith) had a break from the usual daily routine and spent one night at Simon’s family summer house in Saltumstrand. The possibility to sleep as long as we want and waking up in another place felt like a short vacation. Laia woke up first and went for a walk and some observations to the nearby beach. A little bit later Christian joined her and did his daily swim in the north sea. When I woke up they just came back and told me about their nice walk. As I was still a little bit tired I decided to copy the idea and went to the beach. After running on the beach and a fast swim I felt fresh and joint the others having breakfast next to a warm fire in the living room.

Around 11 it was time to say goodbye to the beautiful and comfortable house. Following a “road” on the beach we headed for friends of Simon, William and Agnes. We used the allowance to go by car on the beach, of course, for some observations. Among others we saw one little stint (dværgryle) and two darkbellied brant geese (mørkbuget knortegås) roosting on the beach. Arrived at Williams house he showed us around. He is with 88 years the oldest active ringer in Denmark and uses several different traps to catch the birds. His garden is always filled with many birds, as the garden is very natural and domestic finches, which he keeps in his garden, attract them. So, he can ring many birds just in his garden next to his house. Then we enjoyed coffee, tea and lunch at their place.

IMG 20190925 123529

On the roadtrip back home we had a stop because Simon thought that he has seen a pallid harrier (steppehøg). Unfortunately it flew away and we could not find it again. However, we saw some red kites (rød glente), peregrine falcon (vandrefalk), golden plovers (hjejle) and lapwings (vibe) instead. In the late afternoon we came back to the station.

While Michael is preparing food for dinner Yehonatan and Laia went out to put a trap for ducks in the reed. Let`s see if it works that well than the traps in Williams garden.

A nice first day

tirsdag 24. september 2019
af Koen Stork

Today we were ringing at Kabeltrommelkrattet, Yehonathan and I were going up early to open the nets while Michael, Simon and Christian joined later. The ringing was actually quite fun! One of the first birds in the nets was a Snipe (Dobbeltbekkasin)! It is the first one to be ringed at Kabeltrommelkrattet. Apart from that we caught the usual species. Field observations from the ringing spot were also nice with Little Bunting (Dværgværling), Lapland Longspur (Laplandsværling), Great Grey Shrike (Stor Tornskade) (flying around the nets as well, exciting!) and a Great Skua (Storkjove) passing right overhead. We closed the nets at 10:30 which proved to be exactly the right time as it was our first round without a single bird in the nets.

71169748 2288135804647511 3990951970142683136 n

Judith and Laia were out doing observations with Knud from Verdens Ende 3. Their highlights included the lingering Black Scoter (Amerikansk Sortand) and migrating Brant geese (Knortegås).

71170222 375215176715582 3232385673935716352 n

After the ringing, Michael and I went to see the Black Scoter (Amerikansk Sortand) and we did! A life tick for us both! We’re enjoying a nice gin-tonic for celebration as I’m writing this.

At 13:00, Yehonathan, Simon, Christian, Judith and Laia left on a trip to Rubjerg Knude and Simons summer house in Blokhus. It was a foggy experience at Rubjerg Knude, which is a dune on a steep cliff to the ocean which slowly coming nearer to the lighthouse that is standing on top. There is already some construction work around the lighthouse going on and it is planned to move the lighthouse in around four weeks, as it otherwise will fall into the sea eventually.

Michael went out birding in the afternoon and saw some nice things such as the Yellow-browed warbler (Hvidbrynet Løvsanger) that was found this morning, a Snow Bunting (Snespurv) and a good number of ringed Great Black-backed Gulls (Svartbag): 11!

At Simons summer cabin, the others heated the house with firewood and Judith and Christian went swimming at the large beach behind the house. Birdwise nothing exciting happened to the roadtrip people during that day, except maybe the migrating Pink-footed Geese (Kortnæbbet Gås) at low height. The evening was dominated by making and having dinner and playing games.

For the rest of the day here at the station, we just did the usual stuff, went shopping and had some good talks!

A windy day

IMG 0577

Today we split the team of the bird observatory in order to cover both ringing and observations.

While Yehonatan, Judith and I were ringing at Sardinkrattet, Christian was at Vardens Ende 3 doing observations. The highlights of today´s observations were that the American Scoter (Amerikansk Sortand) was still out there. Also, there were some Richard´s Pipits (Storpiber) in the area. And finally, the best bird of the morning was a Pomarine Skua (Mellemkjove).

The weather today was windy (SØ) and this didn´t help with the ringing and we had to close the nets early. We ringed only 10 birds this morning which you can find below.

It was nice to see the Goldcrest (Fuglekonge).KJMW0514

After lunch, Judith and Christian went for the daily swimming at the Kattegat Sea and I joined them as the previous days (but today just walking in the water).IMG 0588

Today arrived Koen and Michael to the station they joined us at lunchtime. Afterwards, we had a moult session where we studied the different moult strategies and we did a practical exercise with Eurasian Siskin (Grønsisken).IMG 3361

A hot day

søndag 22. september 2019
af Yehonatan ben aroia

The morning started in a very nice ringing with me, Judith, Laia and Morten. The morning was very foggy and almost no visibility which helped us in the ringing because the birds couldn’t see the nets very well as sometimes so the first round was busy with almost 20 birds and the other rounds where a bit slower but we still ended up with 34 bird. While we where out at Kabeltrommelkrattet, Michael Ancher was taking care of the ringing at Jennes Sø.


70689959 425469858077734 6247106807651631104 n

here is a Chiffchaf (Gransanger) that liked Judith very much.

In this time Christian was doing observation in worlds end 3 where we usually sit. It was quite a slow morning for seabirds, much slower than the days before but still a few skuas here and there, but a nice flock of around 50 Brent geese were the highlight.

When we finished the ringing, our new volunteer Laia and Judith joind Knud for a tour about the life project that started in the observatory and then the area around it. Many people joined the tour and Knud made it very interesting with his knowledge about the area.

After all the morning activities we all had some rest in the apartment and had some lunch together (leftovers from yesterday as usual…) and then Laia, Chris and Judith went for shopping so we can a have a nice evening BBQ while I was doing some of the indoor and computer work in the station and when they came back they went for a swim.

Later in the evening we had a nice vegetarian BBQ for dinner and then some sleep.

Trip to Råbjerg Mile

lørdag 21. september 2019
af Judith Kloibhofer

Today we were ringing in two places, Simon, Yehonatan, Christian, Laia and I went to Kabeltrommelkrattet and Michael Ancher did the ringing in Jennes Sø. With 43 species in Jennes Sø and 23 in Kabeltrommelkrattet it was a nice but not very stressful morning. In Kabeltrommelkrattet the caught birds slowed down after two hours, so we divided and Christian and Laia went for observations and joined Morten in Worlds End I. The highlights there were two shags (topskarv) and pendulin tits (Pungmejser). Afterwards they went for a walk to the beach to watch the seabirds closer.

71181930 457578114835872 3527805099491459072 n

In the afternoon all of us went with Knud to the Dunelakes (Milesøerne) next to Råbjerg Mile. Our guests in the apartment (Lis & Erik) joined us and enjoyed their last day up here in northern jutland. You can read more about how they have experienced their stay up here in Skagen in one of the following blogs. Knud seems not only being a keen birdwatcher he is also a very good tour guide. We learnt many interesting things about this region and saw beautiful hidden places, far away from all the tourists. The landscape and all the plants in the heaths and on the dunes were very impressing. When we arrived at one of Knuds favourite birdwatching places in this area next to the Milesøerne we startet counting. Unfortunately we could not see many birds there. But we still had some highlights: two adult cranes (traner), one little grebe (lille lappedykker) and some pintails (spidsand).

When we came back to the station we enjoyed the nice and calm weather while going swimming. This time Laia, the new volunteer, joined us. Let’s see if she will start participating in our challenge to go swimming every day till November. Not only swimming is very nice with sun and nearly no wind, also the radar is working well. So, we used the evening for observing birds flying over sea with the radar. In the meanwhile Yehonatan prepared some nice food and went to bed soon because all of us were really tired from that long day.
