A great northern diver at Blåvand !

fredag 27. marts 2026
af Hanelie Sidhu & Clara Delahaye & Mathilde Lundt Larsen

Observation : 

Under the Blåvand sun, there’s no more sign of fog at the moment… and the sunrise brings its own share of enchantment…

Today was truly a beautiful day.
We spotted over 3,000 common scoters [sortand] migrating north, which really marks the start of the migration season – much to our delight.
Through our binoculars, we were also able to spot more than a dozen sandwich terns [splitterne], some velvet scoters [fløjsand] and a great northern diver [islom] resting on the waves.

Then, in the afternoon, during the count of resting birds, there was a massive number of herring gulls – over 800 of them – lying on the beach !

Todays observations can be seen here.


Ringing : 

Today we woke up rejuvenated to get ringing again after a couple of days of bad ringing weather. So when the sun slowly broke through and we were catching a nice amount of birds in the first few rounds. 

There were a lot of recaptures today but also some new arrivals, which were nice to see - some indications of spring with a chiffchaff (gransanger) and the highlight of today: the first black redstart (husrødstjert) of the spring. This was a younger one (2k), so the sex was not identifiable.

We also caught quite a number of blackbirds (solsort) and a couple of yellowhammers, a male and a female, that were ringed in different years - one last year in spring 2025 and one back in 2022, that were now flying together.

Later, we enjoyed the sun and blue skies over Blåvand today by a walk by the dunes and the beach. Another great day in Blåvand!

A birdwatching trip to Tipmosen and Nyeng

torsdag 26. marts 2026
af Clara Delahaye & Hanelie Sidhu

Observation :

Today the weather was finally favourable for the migration count - youpii- !
Above the churning waves, we spotted over 600 common scoters [sortand], 4 gannets [sule], 2 velvet scoters [fløjlsand] and 1 sandwich tern [split tern] .

It was a wonderful morning of birdwatching, as there were four of us counting from the dunes today. Indeed, Hanelie and Mathilde joined Thomas and me [Clara] because the wind was too strong to set the nets ! 

Todays observations can be seen here. 

 

After the obs we heated up at the station, had some lunch and took some naps, I got a nice fire burning in the stove and moved a cozy chair in front of it where I also napped a little, very warm and comfortable.

For the afternoon, we had planned a birdwatching trip to Tipmosen and Nyeng. Sharing a Flextaxi we did not need to fight against the wind on bikes and got there quite comfortably. At Tipmosen the highlight was an adult male Hen Harrier “Blå Kærhøg”, that Mathilde spotted first and that showed very nice so we could all enjoy it. We also had some passerines, although expected, my passerine highlight was two Mistle Thrushes “Misteldrossel” on the Golf fields. It is beautiful Thrushes.

At Nyeng there were many waders and it was a (windy) pleasure to be birdwatching out there: lot of Dunlins “Almindelig Ryle”, Curlews “Storspove”, also Pintails “Spidsand” we saw a flow of Brent Geese “Knortegås” and Bar-tailed Godwits “Lille Kobersneppe”, Goldeneyes “Hvinnand”, Golden Plovers “Hjeile” just turning into summer plumage… Bevor the high tide arrived, the sandbanks were full of birds.

It was a really nice trip, although the landscape here at the tip is beautiful, from time to time it feels very good to also get out a bit.

Tomorrow the wind will finally be good for ringing, so we are looking forward to hopefully a good day, now after some days with closed nets.

Windy day brings forth the sandpipers

onsdag 25. marts 2026
af Mathilde Lundt Larsen

I (Mathilde) arrived to the station on Monday to stay until the end of the week. I have been spending the time so far getting reacquainted with Blåvand, which I have missed over the winter. It is so nice to be back for a taste of early spring birds and spent time with people at the station.

Today was another windy day - with wind up to 14 m/s as well as rain we could not open the nets today either. Instead, I went on a walk when the rain stopped mid-morning out over the heath and through to Reginevej, where I found a singing robin.

Hanelie saw a woodcock (skovsneppe) in the station garden, so hopefully we could catch one in the nets soon enough!

Clara counted the resting birds at the beach, when they returned after the worst of the stormy morning.

Todays observations can be seen here.

Later Hanelie and I went out to Grønningen where there were a range of birds foraging in the wet fields.

The golden plovers (hjejle) were numerous with a flock of 28 and currently changing to their summer plumage, as well as lapwings (vibe), turnstones (stenvender), wigeons (pibeand), teals (krikand) and starlings (stær).

Lapwing.jpegLapwing "Vibe", picture by Hanelie

We found a group of purple sandpipers, which were nice to see so close and interesting to see them not at the coast - perhaps they sought shelter because of the strong winds and high waves. On the way back there were grey herons flying and a multitude of gulls as we biked back against the wind.

The first Sandwich Terns of the season!

tirsdag 24. marts 2026
af Hanelie Sidhu & Clara Delahaye

Observation :

The fog continues to hang over Blavand... but at least, whilst counting the resting birds on the beach, we spotted the first sandwich terns of the season – five of them !

Ringing:

No ringing today due to heavy wind and rain. An opportunity to do some indoor work on my data project, datacheck and to wash the birdbags.

Less fog and a new moth species for the season: Grågul Frostmåler

mandag 23. marts 2026
af Hanelie Sidhu & Clara Delahaye

Observation :

At last, the weather conditions were more favourable today for observing the migration – phew!
Between counting red-throated divers and flocks of common scoters, we spotted several porpoise whales near the reef. We’ve been seeing their dark fins for several days now.
Did you know that ‘Marsvin’ means ‘sea pig’ in Old Norse? And that ‘Porpoise Whale’ (the English name) comes from ‘porkopiscis’, which meant ‘pig-fish’?
Apart from this amusing anecdote, we also saw a grey seal resting with its head above the water near the shore, and a common seal !

Today´s observations of observers in the area can be seen here.

Ringing:

This morning was less foggy, so it was a bit more fun to walk the rounds although still few birds. I walked around a bit, not so far from the station I saw some Linnets “Tornirisk” and a Woodcock “Skovsneppe”. I hope they will also find their way into the nets. The highlights in the nets today were a pair of Yellowhammers “Gulspurv”, male and female as well as a Goldfinch “Stillits”.

Two Redwings went in the nets, a juvenile and another 3k+, unfortunately the adult had hardly any fat or muscle and was very light.

I would like to give a small update on the moths, as in my last seasons here I have two traps out but with the often so foggy, cold or windy weather, the moth catching was not very successful so far. I have only caught four species in the traps and as always, there is Scoliopterix libatrix “Husmoderugle” in the bunkers. Today I had a new species for the season Agriopis marginaria “Grågul frostmåler”.

Of fog, birds, bats, birdwatchers and wolves

søndag 22. marts 2026
af Hanelie Sidhu & Clara Delahaye

Observation :

There was still fog everywhere this morning. Unfortunately, no standard migration monitoring today. Luckily, Henrik spotted one of his favourite birds… drum roll… the Caspian gull, [Kaspisk Måge] Larus cachinnans !

Ringing:

The third day in a row in fog. Morten joined me today for the first rounds but it was again very few birds. The highlight was a 3K+ Redwing “Vindrossel”.

Some of the Goldcrests” Fuglekonge” of the last days flew in the nets again, but there was also one that Lua ringed last November.

22-03-2026.png

DKU left Blåvand today, they successfully finished their meeting yesterday evening. On his way home from the meeting, Henrik was so lucky again to see even several wolves!

Later in the afternoon it cleared up and I went to my favorite bat bunker, the bog and the beach. Today I found a new bat species in the bunker. While it is mostly the Water bat “Vandflagermus” – Myotis dabentonii that is resting in the bunker, a bigger bat caught my attention. I found out, that it is the Pond bat “Damflagermus” – Myotis dasycneme. It is similar to the water bat but bigger and has larger nasal tubercles. A comparison with the nose of one of the water bats confirmed that. That was a quite cool discovery!

I continued to the beach where the ringed Plovers are already active. The bog was rather quiet but a Linnet “Tornirisk” was singing on a bush close to me, some Skylarks “Sanglærke” were singing, I saw two Stonechats “Sortstrubet Bynkefugl” and one Redwing “Vindrossel” without ring.

The second day of the DKU meeting

lørdag 21. marts 2026
af Clara Delahaye & Hanelie Sidhu

Observation:

This was my second day of birdwatching with Thomas, and the fog refused to lift completely. It prefered to envelop the whole of Blavand and hide the distant silhouettes of the scoters, red-throated divers and other delighted birds.
We were still able to count for an hour, perched high on the dunes, eyes glued to the telescope.
We really hope the weather improves over the next few days so that we can return to standard counting methods.
In the meantime, here is today’s drawing (we saw eight of them flying north in the early morning).

Ringing:


When we opened, the it looked like the sun would manage today to break thought the clouds Indeed, we could do our first round under rather clear sky and it was a quite good round. But the sea fog is fast ant Blåvandshuk and unfortunately, the Radar was right. When we left the lab, the fog had captured Denmark´s westernmost point and also the birds thought that this was not a nice weather to fly. So after, rounds were rather slow. We caught another Chiffchaff “Gransanger” today and as the observers needed to cancel observations, Clara followed us on some rounds later in the morning and saw her first birds in hand!

21-03-2026.png

Paula left the station today, we wish her all the best for her next adventures and hopefully she will get some more birds and especially better weather at her next stay.

While we were walking through the fog, DKU continued their meeting today.

Many birdwatchers and few birds in the fog

fredag 20. marts 2026
af Clara Delahaye & Hanelie Sidhu

Morning observations:

In the early morning, the fog refused to lift from the banks of Blavand. From the top of the dunes, all we could hear were the cries of the herring gulls, the horizon was shrouded in a thick veil of mystery. Few birds were to be seen, whilst the toads, for their part, were out in force.
We therefore decided to take a fresh look at the birds species we know so well at Blavand. Here is the drawing of the day.

Yesterday's sunny weather did not last til today. It was already quite foggy when we opened the nets, and the fog only deepened over the next few hours. Today, Xenia joined the ringing. Unfortunately, the bad weather also did not bring many birds. My highlight was a recapture of a  Yellowhammer "Gulspurv", a pretty adult male that Bent ringed in 2023.

With its bright yellow, it brought some light in the grey day! Some Goldcrests “Fuglekonge” were around, but it was also some recaptures from yesterday.

But we had some nice talks over some tea at the station, and after it was mostly an indoor day for us, as the fog did not clear…

In the late afternoon, the first members of DKU, the DOFbasn quality assurance, arrived for their meeting this weekend.

Birds are back!

torsdag 19. marts 2026
af Paula Feuchtmeyer

Yesterday’s hopes turned into reality. The clear night delivered exactly what we had been wishing for – finally some more birds again!

By the end of the ringing session, we had ringed a total of 27 individuals from 12 different species.

19-03-2026.png

The highlights of the day were two European goldfinches “stillitz”. These beautiful birds never fail to impress and it’s always nice to see one up close in the hand.

Another nice moment came with the capture of a redwing “vindrossel”. Unlike their relatives – the often caught blackbirds “solsort” and song trushes “sangdrossel” – redwings a rather rare.

The Chiffchaffs arrived

The morning started a bit windy and according to DMI it would stay like that for the next five hours. So we had a reduced number of nets open, but actually, the wind turned out to be lower than expected. Nevertheless, the birds did not come. We only caught three birds in the whole five hours, two of them Chiffchaffs “Gransanger” – at least a little spring feeling. Also the adders “hugorm” start coming out, when the sun manages to get through to Blåvand. So let´s hope for some more spring with more birds in the next weeks.

We also received a recapture letter of the Dunnock “Jernspurv” with foreign danish ring, that we caught some days ago. At Hanstholm Fyr at the ringing site of the Nordvestjysk Ringmækergruppe. Always exciting to get back recapture letters.

We are hoping that that the clear night will bring us some birds tomorrow.
