MARTS / MARCH 2026
⬇️ English below ⬇️
Marts var i Blåvand-området en mild og relativt solrig måned med temperaturer over det normale, men lokalt ikke den varmeste i de seneste år. Nedbøren lå på et moderat niveau.
Der var fuld dækning på ringmærkningen med Hanelie som tilbagevendende hovedringmærker, men vi havde også besøg af Paula Feuchtmeyer (DE) og Morgan Jarmer (DK) som gæsteringmærkere.
I marts 2026 var ringmærkningen generelt præget af en langsom sæsonstart med meget tåge og blæst, mange små fangstdage og en høj andel genfangster, men med enkelte tydelige opblomstringer midt og sidst på måneden. Den bedste dag var 19. marts, hvor der blev ringmærket 27 individer fordelt på 12 arter, mens 8. marts gav 14 nye fugle, og 29. marts gav i alt 26 fugle, dog flest genfangster. Blandt de spændende ringmærkningsarter var månedens første rødtoppet fuglekonge og en lokal sjældenhed i form af sumpmejse den 3. marts, en grønirisk med norsk ring den 5. marts, sæsonens første vindrossel og gransanger den 14. marts, to stillitser og endnu en vindrossel den 19. marts samt månedens første husrødstjert den 27. marts. Samlet tegner marts sig derfor som en lidt træg, vejrpåvirket måned, men med flere fine forårstegn og enkelte virkelig interessante fugle i nettene. Martstotalen blev 246, hvilket er det laveste siden 2021 med kun 190 fugle og desuden langt under gennemsnittet for de seneste 10 år.
Trækobservationer blev dækket af Clara Delahaye fra Frankrig fra d. 20/3 og frem med assistance fra både David Manstrup, Thomas Kristiensen og Henrik Böhmer. Vi havde også besøg af Sverre Porsgaard, der var observatør sidste efterår. De første dage af perioden var præget af tåge og det gjorde betingelserne svære for standardtællinger. Da der først kom hul på bylden d. 27/3 var der endelig godt med sortænder, lommer og som sædvanligt lidt sydtræk af både ænder og vadere. Største dagstotal for nordtrækkende sortand var 4410 d. 28/3. Tallene generelt var dog ikke prangende og de store dage med sydtrækkende ænder udeblev helt.
Af andre observationer blev der set en nordtrækkende hvidvinget måge 14/3 og en sydtrækkende 4k middelhavssølvmåge d. 27/3. Der blev også set en rastende islom d. 27/3.
Noget andet der kendetegnede marts, var det relativt høje antal af kaspisk måge. Marts er typisk en måned hvor antallet af kaspiske måger falder markant på landsplan og vi ser typisk ikke ret mange i Blåvand heller. Igennem hele marts 2026 var der 9-10 rastende fugle og d. 31/3 hele 40 fugle, som er klar marts-rekord for arten på hukket.

March in the Blåvand area was a mild and relatively sunny month, with above-normal temperatures, though locally it was not the warmest March in recent years. Precipitation was at a moderate level.
Ringing coverage was complete, with Hanelie serving as the returning principal ringer, but we also welcomed Paula Feuchtmeyer (DE) and Morgan Jarmer (DK) as guest ringers.
In March 2026, ringing was generally characterised by a slow start to the season, with frequent fog and strong winds, many small catch days, and a high proportion of recaptures, though with a few clear upturns in the middle and at the end of the month. The best day was 19 March, when 27 individuals of 12 species were ringed, while 8 March produced 14 new birds, and 29 March yielded a total of 26 birds, though mostly recaptures. Among the more notable ringing species were the first Firecrest of the month on 3 March, along with a locally rare Marsh Tit; a Greenfinch carrying a Norwegian ring on 5 March; the first Redwing and Chiffchaff of the season on 14 March; two Goldfinches and another Redwing on 19 March; and the month’s first Black Redstart on 27 March. Overall, March can therefore be described as a somewhat sluggish, weather-affected month, but still with several encouraging signs of spring and a few genuinely interesting birds in the nets. The March total came to 246 birds, the lowest since 2021, when only 190 were ringed, and also well below the average for the past ten years.
Migration observations were covered by Clara Delahaye from France from 20 March onwards, with assistance from David Manstrup, Thomas Kristiansen, and Henrik Böhmer. We also had a visit from Sverre Porsgaard, who had been an observer the previous autumn.
The first days of the period were marked by fog, which made conditions difficult for standard counts. When things finally began to improve on 27 March, there were at last good numbers of Common Scoters and divers, and, as usual, some southbound movement of both ducks and waders. The highest day total for northbound Common Scoter was 4410 on 28 March. Overall, the numbers were not impressive, and the big days of southbound duck migration failed entirely.
Among other observations, a northbound Iceland Gull was seen on 14 March, and a southbound 4cy Yellow-legged Gull was seen on 27 March. A Great Northern Diver was also observed resting on 27 March.
Another feature of March 2026 was the relatively high number of Caspian Gulls. March is typically a month when numbers of Caspian Gulls decline markedly at the national level, and we do not usually see many in Blåvand either. Throughout March 2026, there were 9–10 birds present, and on 31 March as many as 40 birds were recorded, which is a clear March record for the species at Blåvandshuk.
