Hello everyone!

As has been the norm for the past few weeks, for today's fieldwork we split into two teams.  Martina and I left for Kabeltromeln to go ringing at 4:00 am, and Rita and Nathan went to World's End 3 at Grenen to do the daily autumn migration seawatch.  Brief rains in the first two hours of the ringing hampered bird activity, but when the rains stopped we managed to catch a good assortment of resident species such as song thrush (sangdrossel), blackbird (solsort), reed bunting (rørspurv), chaffinch (bogfinke), and a gorgeous lesser redpoll (lille gråsisken), as well as a few migrants, such as willow warbler (løvsanger).  Interestingly, a high proportion of the birds today were recaptures, likely a result of us having ringed a decent number of this season's juveniles, and low rates of overnight migration.  Alice and her mother, who is currently visiting Skagen, came by the ringing for the last few hours, and not long after their arrival, the day's unequivocal highlight flew into our nets.  An after second calendar year (i.e., adult) reed warbler (rørsanger) is, on its own, no big surprise seeing that a lot of them breed around here.  But closer inspection of the aluminium ring already fitted around its leg revealed an exciting 9-letter word: "STOCKHOLM." 

Recapture Rørsanger from Sweden

Reed warblers (rørsanger), Acrocephalus scirpaceus, are common breeding birds in the wetlands around Skagen. They are very hard to distinguish from their sister species marsh warbler (kærsanger) unless they are singing since their songs are very distinct. The physical appearance, however, it very similar so on migration when they are not singing it is always a challenge to distinguish the two species and even when you hold them in your hand it can be hard. Both migrate from Sweden through Denmark to West Africa. Marsh warblers migrate quite a bit further and therefore earlier. They also almost exclusively use the „Eastern Flyway“ crossing the Arabic peninsular on their way to Africa, whereas reed warblers stay in the north longer and mainly choose the „Western Flyway“ passing the Mediteranean at the Channel of Gibraltar. Since reed warblers are very common breeding birds in wetland areas and most bird ringing stations in Europe are set up in such habitats, reed warblers are also a common species to recapture. This means that we have very good information on how and when and where they migrate. There are recaptures of birds as long as 12 years after they were ringed, which is quite impressive considering the small size and the amount of travel such a bird conducts each year! All we know about the bird we caught today so far, is that it was not born this year. Who knows how many times this small animal has flown across the equator in its life. It is genuinely marvelous that a minute feathered creature brings tales of Afrotropical scrublands shared with hornbills, sunbirds, and zebra, to cold windswept dunes here in Skagen. With regards to this blog's corny title, its unlikely our Swedish-ring-wearing warbler friend felt any admiration for its temporary captors (us), but its political-border-oblivious story sure held us captive with affection. We will report the bird to the Swedish ringing center and hopefully soon know more about its biography.

All the while, Rita and Nathan had quite an exciting seawatch, reporting a Manx shearwater (Almindelig Skråpe) passing by close to shore, black terns (sortterne), and a great skua (storkjove) that landed on the beach for a while!

The rest of the day was spent resting, inputting data, and repairing nets.  Tomorrow, we look forward to good migration conditions, which hopefully bring good birds into our nets and flying by the shore!

Once upon a time in the early morning hours, foreign bird banders up at KAB asked a local birder if there was ever a time of year in Skagen with less wind, and the local smirked and said ‘’no, it’s always windy’’. Though it is always somewhat windy, the past couple mornings have been windier than usual and have kept us from opening our mist nets up at KAB. However, members of our team were able to conduct a migration and roost count at the tip. Around 4:30 AM armed with their scopes, binoculars, seats, and counters Alice and Max trekked through the sandy beach to the little dune overlooking the tip, the wide beach dotted with colorful pebbles, and the seas. Once at the top, they set up their scopes in the hopes of catching a glimpse of the expected migratory species that usually appear this time of year. In the first hour of observation, the team spotted two black terns, alongside the many herring gulls and common terns usually present on the beach. By 7AM the team accompanied by Knud spotted a couple exciting species including different types of skuas such as: great skuas, arctic skuas, and a long-tailed skua that stole the show.

The morning observations ended at around 9AM after the routine 4 hour counting process, and Martina joined the group at the tip to attempt to resight some ringed gulls. With the aid of her scope she was able to get a good look at a couple different rings, but she soon started to feel the effects of the wind. As the wind started to pick up, the scope started to shake and as Martina held on and attempted to continue her work, the wind increased nearly toppling the scope. Unfortunately, the combination of strong winds, tourists enjoying the beach but often unintentionally flushing the birds cut Martina’s mission short, but fortunately she did not leave empty handed.

The winds do not only affect our ability to open the mist nets, but also have an impact on migration depending on their direction and intensity. The effects of the wind can also been seen on the tourists attempting to walk to the tip, bikers biking to town at a snails pace, and on the sand as well as dunes near the beach. So, for all of those still out there braving the winds, cover up and hold on! Coz what’s Skagen without a little wind?

The beach around here is always nice for bird watching, however, on days with so-called ‘bad’ weather it may be especially so. You never know which rarity a storm might wash to shore. So when it is stormy and rainy it is always good to go take a look at the beach. It is not quite as peasant, of course, as doing a bird count in the sunshine.

This morning started just after midnight for Max and me, since we had decided to try our luck with night catching. Rain at night should have made it possible, however, the forecasted rain didn’t come at the time it was forecasted, so visibility was too good and birds could get away from us. It was a good chance to get used to using the thermal binoculars, however.

After one hour of sleep, I got up again to check the weather forecast and contrary to what was expected last night, in the morning it seemed like most of the rain would pass just south of us. So I told Nathan an Rita that it was okay to try and do the count and myself went to open some nets in Grenen (not all of them since it was unclear if it was going to rain or not and I needed to be prepared and able to close quickly if necessary. That’s also what I did after an hour, as it already started to rain.

The forecast said it would stop after two hours, so I took my chance to check out the beach and saw a small flock of sanderlings next to a lot of roosting gulls and terns. When the rain stopped, I went to open the nets again because not only on shore but also inland a storm could have brought nice birds. And maybe it did, or it was just coincidence that just after the rain there were two rosefinches (karmindompap) in the net. One juvenile and an adult, possible a young and a parent travelling together.

Other than that, not a lot of birds have been called, although downscaled to the lower number of nets and hours the number of birds was comparable to the last few days. And the mix of species was similar too. Tomorrow winds will drastically change and the clouds between Norway and us will clear up so as to allow migration to finally get moving for real. It will probably be too windy tomorrow to find out, however, on Wednesday we will be prepared for larger numbers of birds again.

In the afternoon, our guests for this week arrived – a little later than usual because of illness. Also, we did some data entry while it was raining outside. While at work at the computer we also received some recovery data on birds ringed by this station and found in Spain. It is always nice, when one of your birds gets reported somewhere else, even though this may not be the main use of bird ringing any more, it is still just amazing to see how the birds travel such long distances. Especially when it is a tiny bird like a chiffchaff (gransanger), which was ringed at the end of September 2009 in Skagen and recovered at the end of November in the same year 2500 km away in Córdoba, Spain. Whyever the information took more than 10 years to arrive here, we do not know but we are happy to report that that chiffchaff was alive and well when it was captured and released in Spain.

The same is unfortunately not true for a songthrush which we ringed here in 2018 only for it to be shot in Spain 3 months later. It will always remain a mystery why anybody would shoot birds, unless they really need them for food – which is probably not true for most people in Spain, and if it were, wouldn’t you rather take a bigger bird?

In the evening Knud took Nathan, Max and me to Jerup strand to go bird watching there. It was a very successful trip as we saw lots of shorebirds, including grey plovers, dunlins and ringed plovers (all in the picture below), cranes (an adult and a juvenile in the picture) and we also managed to read some gull rings again.

Also, to make it a perfect day, we got rained on yet again, but the light after the rain was just amazing. I guess, it was exactly that which makes this area so famous for painters.

Hello everyone !

Like yesterday, today was a slow day for birds; but some nice divers (great and black throated) were spotted by Max, Alice and Erik.

Amazing high quality picture of a black-throated diver taken by Max

Another clutch of ring plovers has also been sighted on the beach and we are looking forward to ringing them !

When it comes to the ringing, we had few birds in quantity but 10 different species in the nets which is always enjoyable. On the way back to the light house, Martina spotted the Crested Lark near the parking lot near the dunes.

Later in the day, Alice went with Jørgen Kabel to see a Polygonia C-album; it only has been observed a couple of times in Skagen !

Tonight, Max and Martina are going to do some night catching on the beach and we all wish them good luck !

That is all for today folks !

See you tomorrow

Greetings!

Unfortunately, there is not much to report on the bird front today. While the past few days have been quite productive for ringing and seawatching (our two main fieldwork projects for the autumn), today was an exception. Overnight and throughout the day it's been quite cloudy, and for southbound migratory birds coming from Norway, Sweden, and perhaps elsewhere, making the flight across the Kattegat or Skagerrak in a dense grey fog with no visibility is far from preferable. Hence, few migrants arrived here in Skagen; Rita and Nathan reported a very inactive seawatch at World's End 3, and Martina, Alice, and I had a similarly slow day of ringing with 17 birds, the highlights being 2 Icterine Warblers (Gulbug) and 1 Reed Bunting (Rørspurv). However, days like today are fascinating displays of the relevance of weather conditions to bird migration, and truly, a day can never even be considered mediocre when there's birds involved!

After their seawatch, Rita and Nathan went into town (while Martina, Alice, and I rested) to do some grocery shopping and search for the continuing Little Auk "Søkonge" in the Skagen harbor. This bird was found a few days ago by local birders, and is quite a rarity for the summer! Little Auks breed in large colonies on islands in the North Atlantic within the arctic circle, including Greenland, Svalbard, Jan Mayen, Franz Joseph Land, and Novaya Zemyla among others (though there are some small colonies known in the extreme North Pacific in the Bering Strait). They regularly spend their winters in the waters surrounding Skagen, so in general they're not a rarity, but it's the time of year that makes this individual interesting, Perhaps this bird migrated prematurely, or got lost while on a foraging foray, but what's for certain is that this bird is behaving strange. After a short search, Rita and Nathan found the auk, and were surprised to find it approach within a few meters of them, allowing wonderful views and photo opportunities.

Later in the afternoon, Knud Pedersen drove Martina, Nathan, and I to Nordstrand so we could walk to the nearby Cormorant "Skarv" Lake to finish clearing lanes for mist nets at at a new CES ringing site. CES, which stands for "Constant Effort Sites," is a standardized bird ringing program which seeks to regularly ring birds at the same site every year through the breeding season. The data collected from CES ringing is incredibly valuable for estimating the survivorship and reproductive output of local bird populations, and documenting changes in those variables over time. After several hours of hard work, mosquito bites, and water logged boots, we finished cutting all of the net lanes, and are excited to begin ringing at this site next year!

Cheers!
Max

 Local observations of the day in DOFBasen

This morning had been very good for both the ringing and observations teams. The weather did not look promising at first with the sky completely covered in clouds, but it didn't stop the birds from coming. Martina, Rita, and Nathan, were at the ringing and enjoyed the lucky captures of not one but two Green sandpipers (Svaleklire), and one Red-backed Shrike (Rødrygget Tornskade). It was the first time for Nathan and Rita to get these species in the nets.

Early this morning while Nathan and I were doing our daily migration counts, we received an exciting message from the ringing team up at KAB. The team composed of Martina, Max, and Alice had caught something extra special in their mist nets, a wryneck (Vendehals), a first for many of us. The wryneck is part of the woodpecker family and is capable of doing extraordinarily strange movements with its neck. It is said that the movements the bird exhibits are a threat display to scare away predators. In fact, they can turn their head nearly 180 degrees and the snake-like movement has given them the nickname of ‘’snake bird’’ in parts of the world.

While Nathan rushed to catch a glimpse of the bird and take the necessary photographs after it had been rung, I caught three Common Kestrels (Tårnfalk) in my scope down by the beach. Much to my delight, the juvenile was practicing its flying abilities in the dunes and I was briefly able to watch it hone its skills. Over the course of the morning, over 20 individuals of the species were recorded in the area, perched on trees, flying above, and practicing the skills necessary to become an efficient predator.
In the early afternoon, Knud was kind enough to drive our team to the cormorant lake to begin the arduous but necessary task of creating new mist net lanes. Although it will take many days to complete the task and the location seems to be yet another favorite for mosquitoes, many bird species were heard over the course of the activity further confirming the potential of the location for future bird ringing. The location's proximity to a lake combined with a terrain compromising of dunes and reeds is prime habitat for many passerine species, it is, therefore, our hope that new nets at the location will enable us to continue the important work conducted by the Skagen Fuglestation in the form of ringing and data collection.

As ancient ringer’s wisdom says: where there are mosquitos, there are birds. We had a lot of mosquitos today probably due to the changed weather conditions and we had quite a few birds too in the ringing. Since Alice, Nathan and Rita took today off in order to explore a natural area (Lille Vildmoos) further south, it was only me and Max at the ringing today. Luckily, we were helped out by former volunteer Frederik who is staying in Skagen on vacation at the moment with family. We had a couple net checks where we were quite happy to have his help! Like other days, today has been quite windy, however, over night the winds have turned from west to south which made everything just a little different.

We were not overwhelmed with birds nor were there any other species than what we are used to by now, save the robin (rødhals) which appeared in the nets to remind us that winter is not that far away.

We also had a juvenile bearded reedling (skægmejse) which was quite a treat, another one calling from the reeds. All of them are probably local birds, though. Migration is still very slow but the fact that we catch a lot of common whitethroats (tornsanger) and very few of them are ringed now also means that we can get a rather good impression of how big the population really has to be. And I am glad to announce that it is big. Of course, there are big variations between years but this year seems to be rather good for common whitethroat, as other years have been particularly good for blackcaps (munk). And Whitethroats are pretty, like this adult male shows:

Apart from birds it was a very nice morning in nice weather out at Kabeltromlen, hanging out with nice people, catching up with old friends and eating ‘rundstykker’, that a visitor kindly brought to introduce us to traditional Danish breakfast.

The rest of the crew had a fantastic day at the Lille Vildmoos and they managed to see moose which was one of their goals:

Hello everyone !

Today was a great day for birding and for us; we divided in 2 teams so we could both ring in Grenen and count the migrating birds at the beach. Max and Alice went sea watching and they spotted a red phalarope resting on the sand.

Martina, Rita and I ringed a decent amount of birds; a few willow warblers (løvsangers) among them. It is a sign of the beginning of the migration !

I hope everyone had a day as nice as ours and see you tomorrow !

Nathan

Hi all!

Our original plans for today were for Martina, Rita, and Nathan to go ringing at Kabeltromlen, and for myself and Alice to do a seawatch at the tip of Grenen.  Early this morning however, Martina awoke to find rain on the forecast, so ringing had to be cancelled.  Nonetheless, Martina joined me to conduct the seawatch at 4:45.  Compared to the past few days, it was fairly slow.  Foggy conditons overnight likely inhibited most nocturnal migrations, so migratory waders / shorebirds were essentially absent, save for a single Dunlin (Almindelig Ryle), looking stunning in breeding or alternate plumage high up on the beach.  In the first hour of the seawatch, I was able to spot a handful of Northern Fulmars (Mallemuk) distantly arcing over the horizon, simply silhouettes in the intense amber glow of the sunrise. 

A beautiful sunrise from Grenen

Northern Gannet (Sule) numbers were also fairly high, I tallied at least 160 at most, our highest count from the past few days.  Though the offshore realm wasn't at its most active, after the seawatch I spent an hour combing through the mixed gull flocks on the beaches at Grenen searching for color-ringed gulls.  Ultimately, I was able to succesfully read the codes on 6 birds' (2 Great black-backed gulls (Svartbag) and 4 Lesser black-backed gulls (Sildemåge) ) color rings.  We will have to wait a bit until we receive the data from the lessers' rings, but we were able to learn that while one of the great black-backs has remained around northern Denmark its whole life (as far as we can tell), the other was originally ringed in Norway, and has journeyed at least as far as the Netherlands in the past few years!

One of the color-ringed lesser black-backed gulls (Sildemåge) observed today.

While Martina and I seawatched, the others slept in to 6 am or so (that's sleeping in for our standards), and did some work repairing torn mist nets, among other things.  In the afternoon, Simon lead a ringing tour for a large group of tourists in the lighthouse garden.  One Greater Whitethroat (Tornsanger) was caught, and hopefully provided an excellent opportunity to demonstrate to the public the importance of the ringing we conduct here at Skagen Fuglestation.  Soon after the tour, Simon for left for his road trip to Norway: we wish him a wonderful adventure!

The highlight of today was unequivocally celebrating the birthday of Alice, who has been here at Skagen Fuglestation since March!  Before he left, Simon lead us in a Danish birthday song to celebrate Alice.  I can't say the rest of us understood the words we were singing, but it was fun nonetheless!  In the evening, we went to beach for a while, where we played a fun bowling-like game (shamefully, Martina & Rita absolutely obliterated Alice, Nathan, and I's team), and enjoyed a dinner picnic.  Nathan went for a quick swim in the Kattegat, but apparently the water was underwhelmingly not cold.  And, as always, we paid attention to the feathered beasts that surround us, and got to see a juvenile Black Guillemot (Tejst) floating offshore.

Again, we wish Alice the happiest of birthdays, and are so happy to work with her here at Skagen!

Cheers!

Max
