Penduline tit (Remiz pendulinus)

This season we've caught two penduline t**s, both in Flommen as they are a species that rely on reeds for nest sites. They have a characteristic "bandit mask" but in September it's a bit faded (slide 2).
One of these individuals had plastic rings on their left leg (slide 4), this helps us identify individuals in the field for a monitoring programme of penduline t**s in Skåne.

From our data we can see that the penduline tit population has decreased, in 1989 we had ringed a record number of 117 individuals! But since then the numbers have varied between 40-10 individuals per year until 2020 and then we've only caught one penduline tit per year - until this year!

🇸🇪 Pungmes (Remiz pendulinus)

Denna säsongen har vi fångat två pungmesar, båda fångade i Flommen eftersom de är arter som förlitar sig på vass för att bygga bon. De har en karaktäristisk "bandit mask", men i september så är masken lite blekt (bild 2). En av dessa individer hade plastringar på dess vänstra ben (bild 4), detta hjälper oss att identifiera individer i fält för inventering av pungmesar i Skåne.

Från våra data kan vi se att pungmes-populationen har minskat, 1989 hade vi rekordmånga ringmärkta pungmesar med 117 individer! Men sedan dess har siffrorna varierat mellan 40-10 individer per år fram till 2020 och sedan dess har vi bara fångat en individ per år - fram tills iår!

Long-tailed t**s (Aegithalos caudatus)

We've had crazy numbers since we caught our first long-tailed tit of the season on October 2nd, and 143 long-tailed t**s in one day being the record for the season... so far.

We mostly catch the Northern subspecies (Aegithalos caudatus caudatus) with the all white head, but sometimes a continental one (Aegithalos caudatus europaeus) with darker head has joined a family group.

Stjärtmes (Aegithalos caudatus)

Vi har haft galna siffror sedan vi fångade vår första stjärtmes för säsongen den andra oktober, och 143 stjärtmesar på en dag är rekordet för säsongen... än så länge.

Vi fångar främst den nordliga underarten (Aegithalos caudatus caudatus) med helvita huvudet, men ibland hamnar en kontinental underart (Aegithalos caudatus europaeus) med mörkare huvud i en familjegrupp.

Bearded tit (Panurus biarmicus)

The 14th of October we caught a bearded tit, after hearing a flock fly over the lighthouse garden. This individual was a first-year female and the first bearded tit since 2021. We don't often catch bearded t**s in the lighthouse garden, since the start of the standardised ringing in 1980, only six of them have been caught and ringed. In Flommen (our other ringing site in the reed beds) on the other hand, 360 bearded t**s have been caught and ringed since 1980.

Skäggmes (Panurus biarmicus)

Den 14e oktober fångade vi en skäggmes, efter att vi hört en flock flyga över fyrträdgården. Denna individ var en 1k hona och den första skäggmesen sedan 2021. Vi fångar de inte ofta i fyrträdgården, sedan början av den standardiserade ringmärkningen 1980, har bara s*x stycken blivit fångade och ringmärkta. I Flommen (vår andra ringmärkningslokal) å andra sidan, så har 360 skäggmesar blivit fångade och ringmärkta sedan 1980.

Blue tit eruption year!

This year has certainly been an eruption year for blue t**s, on our record day (12th of October) this season we ringed 1795 of them! These eruption years happen when there is low beech mast crop, and the last eruption year was 2012 (as some of our colleagues can remember).

Other species such as lesser spotted woodpecker (Dryobates minor) and coal tit (Periparus ater) follow this cycle as well, and we've caught record numbers of these too!

Since we caught that many blue t**s, there's been some interesting looking individuals (slide 2) with bleached feathers, some odd white feathers and the lack of pigment - in one completely! (slide 3)

In the video you can see how we process the birds on a busy day. A bird is taken out of the bag passed on to get a ring and get aged and s*xed, passed again to check wing length, fat score and lastly get weighed before getting released.

Pallas's leaf warbler / kungsfågelsångare (Phylloscopus proregulus)

Caught and ringed on October 12th, this species is a rarity from Siberia, and this is our 24th ringed one since the standardised ringing started here in 1980!

Tree sparrow / pilfink (Passer montanus)

The tree sparrow is a widespread species and for many people it's considered a "common" species, but the fact is that the species is declining, just like the house sparrow (Passer domesticus).

On the Falsterbo peninsula there are only a few places where the tree sparrow breeds, so it is always nice when we catch them in the nets!

Great tit / talgoxe (Parus major)

The extent of the great tit's "tie" is how we s*x the birds, slide 2 shows a male with an almost entirely black stomach, and slide 3 shows a female without a "tie".

The blackbird - the national bird of Sweden!

Everyone knows the blackbird, both their looks and their song - to no surprise as it's mentioned in a lot of literature, poems, and songs. One of the more widespread thrushes in Europe, that can also be found in Australia and New Zealand, as this species was brought over by colonisers.

Male blackbirds have a characteristic yellow bill but the intensity of the colour changes with age and overall health. As seen here on slide 2 (adult) and 3 (first year).

Idag fick vi uppleva en riktig blåmesinvasion – hela 2 036 fåglar ringmärktes, varav 1 785 var blåmesar! Det är den femte högsta dagsumman för blåmes genom tiderna här vid stationen.
Dagen började ganska stillsamt, men redan under morgonens första rundor fick vi en riktig juvel i näten – en kungsfågelsångare! Sedan tog det fart, och näten fylldes snabbt av blåmesar i strid ström. Tack vare ett väloljat team och ett fint arbetstempo hann vi med alla nätrundor utan problem. Samtidigt utspelade sig ett imponerande skådespel på himlen - en strålande sträckdag med 130 000 ringduvor och närmare 3 000 ormvåkar som samlades över Falsterbonäset i mäktiga skruvar innan många av dem vände in mot fastlandet igen. En dag fylld av fåglar, energi och naturupplevelser av bästa slag – precis som vi gillar det!

——————————————————————————————————

Today we witnessed a true Blue Tit invasion – a total of 2,036 birds were ringed, of which 1,785 were Blue T**s! That makes it the fifth-highest daily total for Blue T**s ever recorded at the station.
The day started off fairly quietly, but already during the first rounds we had a real gem in the nets – a Pallas's Leaf Warbler! After that, things quickly picked up, and the nets soon filled with a steady stream of Blue T**s. Thanks to a well-coordinated team and a good working rhythm, we managed to keep up with all rounds without any issues. Meanwhile, an impressive migration spectacle unfolded overhead: a brilliant day of visible migration with 130,000 Wood Pigeons and close to 3,000 Common Buzzards gathering in majestic spirals over the Falsterbo peninsula before many turned back inland. A day full of birds, energy, and nature experiences at their very best – just the way we like it!

🇬🇧 Lesser spotted woodpecker! (Dendrocopos minor)

Today we've had the pleasure to ring our fourth lesser spotted woodpecker, this one is a first-year (1cy) male.

🇸🇪 Mindre hackspett! (Dendrocopos minor)

Idag hade vi nöjet att ringmärka vår fjärde mindre hackspett, det här är en ettårig (1k) hane.
