Silkehaler og en sen genmelding

Der  har i dette efterår været registreret et par småflokke af silkehaler her i Gedser, så stor var glæden, da der den 24. november pludselig var den ringlende lyd i luften af disse pragtfulde skabninger. Heldigvis satte de sig kortvarigt i naboens grantræ.



Der er masser af røde bær på træer og buske, så vi byder flere af dem velkommen!

 . . . og i aftes lidt før kl. 20 var der igen lyde i luften - denne gang fra 1-2 traner, som fløj rundt i fuldmåneskæret. Håber de fandt et godt sted at sove for natten.

Der kommer løbende genmeldinger ind vedrørende de fugle, vi har ringmærket. Men denne her har været længe undervejs:

En sivsanger, som Jens Christoffersen ringmærkede ved Kroghage, Gedser 7. august 2002, blev genfanget og aflæst 10 dage senere på Po-deltaet i det Nordøstlige Italien.

Genmeldingen har med andre ord været tretten år undervejs!

Heldigvis plejer det at gå meget hurtigere med at få besked!

Trækket er bestemt ikke slut – ingen tid til vinterdvale

Den netop overstået weekend var endnu en påmindelse om at ved Gedser kan der ses på træk hele året. Tro aldrig at træksæsonen er slut. Der kan altid ses trækfugle ved Gedser! Såleds blev det to nye højste dagscifre for to arter i weekenden (hvinand og stor skallesluger)

Således kan der fra nævnte weekend nævnes:
Fløjlsand med 190 trækkende er det den tredje højeste dagscifre.


Ride med 10 trækkende er tredje højeste dagscifre.




Hvinand antallet opnåede den højeste dagscifre på træk med 720 – og det er 160 mere end den tidligere højeste dagscifre!



Rødstrubet lom med 861 når lige ind i top fem med en femte plads (højeste dagscifre er 1510!) også sortstruber lom med 52 ryger ind i top fem med en anden plads.



Og lidt uventet når knopsvane med 426 ind på en femte plads i en top fem med højeste dagscifre.



Endnu en første plads opnår stor skallesluger med 144 trækkende som højeste dagscifre ved Gedser.



Dværgmåge med 1209 når ind på en fjerde højeste dagscifre.



De næste to dage mandag og tirsdag kan rykke en del om på dette – da der masser af kulde, sne og nordlige vinde på vej.

Kom til Gedser og oplev trækket 365 dage om året – pludselige vejrskift og på denne årstid specielt når der kommer temperaturfald og sne – gerne hårdt vejr!

Our last day ringing at Gedser

This was to be the last full day of ringing at Gedser, but rain continued until well after midday so nets were not dropped until around 2pm. That meant that we could use tapes as it was much too late to do a standard session.

We caught a few birds, quite a lot of Blackbirds, with many being recaptures.

 Age 3 male Blackbird (1k Solsort)

There wasn't too much damage after the storm, we had one net down due to the net working too far down the pole until it went over, but the other nets were still safely furled with nothing more than leaves caught on a few. 

 A fallen tree just missed the storage shed.

We have thoroughly enjoyed our autumn at Gedser and have met some wonderful people who put so much time and effort into making the observatory a success. It is a superb ringing site with plenty of nets and sheltered areas so that it is usually possible to open some nets, whatever the direction of the wind. It has been fantastic to monitor the progress of birds on migration, processing mainly passerines, with such obvious visual migration going on all around us. During the time we have been here, 10th September to 15th November, a total of 7547 birds were ringed, 5881 of these by Chris and myself with 2745 of those being Goldcrests. It has been brilliant! 
Thanks to everyone involved with the fuglestation - you are all fantastic.

 
 Chris in the ringing lab - such a luxury, we usually ring out of our car boot.
One of my favourite birds of the autumn.

We hope to come back again one day.

Best wishes to you all,

Stor Tornskade after the storm

We couldn't do standard ringing again. After a start to the day when we thought there may not be any sheltered nets, we were extremely excited to find that we had caught a Great Grey Shrike (Stor Tornskade). Not bad when we only got 13 birds.

 Adult Great Grey Shrike (2k+ Stor Tornskade)



 We had not been able to open any nets until 10:00am, and even then we had to close twice due to squally showers. Earlier, it was really looking as though there was no chance of any birds, and certainly not a new species! Neither of us had ringed Great Grey Shrike (Stor Tornskade) but this bird was processed by me, Denise.

When I recorded this video I would never have imaged the day could bring such a fantastic bird!

Good birding!

A blast of Winter

Another day of strong wind. The direction had shifted slightly so that even the two sheltered nets where we'd been using audiolures were being affected, particularly by the strong gusts that definitely exceeded the forecast.

 The observatory garden looking much less leafy due to strong winds.

We did make a attempt to encourage some finches in first thing in the morning but soon gave up and closed for the day.

Good birding.

A slow, slow day with wind and sun..............and some control details

Yet more very windy weather, but this time with some sunshine. Birds seemed to be more willing to make the crossing and, as we've seen before little alighted in the garden. Hence the very low total for the day.
It really does feel as though migration is almost done. We noticed that the snow poles have been put out alongside the road - it's soon be time for us to be making our way back to the UK too.

Gråsisken with a difference

For the second day running we have been unable to complete a standard session due to the weather, however today we did drop a couple of sheltered nets and play for Redpoll as flocks were heading down to the tip, then working their way North again having decided not to cross the Baltic.

We recaptured three Goldcrest (Fuglekonge) and encouraged some Redpoll (Gråsisken) and Sisken (Grønsisken) down to the nets. The catch included a partially leucistic Lesser Redpoll (Lille Gråsisken) with  patchy white colouration on the head, no black leg colouration and pale flanks.

 The lack of black colouration in the legs was quite stricking 
although claws were the usual dark colour.

Westerly winds - new birds not likely

Adverse weather again - strong winds after much rain during the night. We managed to open enough nettage for a standard session, choosing the most sheltered nets next to vegetation where most of the leaves were already on the ground, but the large numbers of thrushes and finches reluctant to migrate in the conditions stayed high and most avoided the nets.

The first two birds of the day were a couple of 2nd winter Sparrowhawk (Spurvehøg). These were interesting to compare as they were moulting their feathers in slightly different sequences.

 New secondaries, retained primaries.

 One outer tail feather, on each side, retained.


 Second 2nd winter Sparrowhawk male (2k Spurvehøg han) with
head and breast looking more adultlike than first bird.

 Tail moult less advanced - total of six retained retrices

After standand we tried some sound and attracted some Redpoll before the point in the afternoon where the garden was seemingly lifeless, three rounds had produced nothing and nets were closed with no prospect of opening after dark due to the strengthening wind.

However, one of the Lesser Redpoll (Lille Gråsisken) had a golden rather than red poll. This is quite unusual and may be due to a dietry deficiency although the precise cause is unknown.

Spurvehøg day

The rain and wind overnight were terrible so there could be no ringing until the wind calmed. We had a lazy start on this Sunday morning and, after breakfast, Chris went to the tip where he enjoyed watching the passage of Common Buzzard and Sparrowhawk.

I hadn't fail to notice the numbers of Buzzard and Sparrowhawk drifting above, or hurtling around the house on a couple of ocassions, so decided that by 10am it should be possible to drop the large mesh nets on the lawn. I arrived to find one net down due to a peg having pulled out - that really had been some bad weather last night! So, only one net was dropped while I returned to the house for some cord to get the second net properly secured and back in working order. The first  Sparrowhawk    (Spurvehøg), a big female that weighed in at 291g with wing length of 249mm (that's only the measurement from the carpel joint to feather tip) was already in the net when I got back.

When she had been processed I went back to do my net maintenance and had only just completed that when the first net check found another captured female Sparrowhawk, this time an adult

I had just finished collecting all her data when Chris got back so we were able to photograph her before release.

With the wind a little less strong now, Chris opened a few very sheltered nets and used an audiolure for Goldcrest (Fuglekonge), we only got a couple (and there were technical difficulties as the MP3 player kept turning off) so we tried a different player and played Redpoll (Gråsisken) later in the afternoon. There was a bit more success from that - the Redpolls even brought a few other finches with them.

There were a couple more Sparrowhawks, this time much smaller males, but the birds that had been hunting in the strong winds of the early morning had disappeared by mid afternoon. Many probably migrated as Chris had seen about 20 birds leave from the tip in the short time he was there.

Between the rain and windstorm

We were up in time to drop nets well before first light but delayed our start as the rain had not quite cleared as the forecast indicated it would. When the time came to drop nets there were some nets that were too wind effected to use but we still had enough for standard and also deployed the large mesh sparrowhawk nets.

The species count was low but we finished on 80+ birds, mainly Fuglekonge (Goldcrest) and Siskin (Grønsisken) but thanks in part to some good afternoon captures of  Lille Gråsisken (Lesser Redpoll) with the assistance of audiolures.

5th November

There was rain at our usual time to set the nets and as the radar showed more rain at 9am we did not try for standard ringing this morning. When the rain had stopped we went out to take a look at our new noisy neighbours. It was difficult to estimate numbers but they certainly were enjoying what remained of the sugar beet, recently harvested.

There was clearly a new influx of Goldcrest (Fuglekonge) so we dropped just two nets and kept a very close eye on them in the rather cold wind. We were catching for approximately 75 minutes during which time there were no retraps.

Yesterday's Perleugle, Sprawks in black and white and a Swedish control

For anyone who missed the update on yesterday's blog - we did a second Tengmalm's Owl (Perleugle) last night. This bird had flight feathers of all the same age so it is a bird hatched this year.

 
 Tengmalms Owl Age 3 (Perleugle 1k)

 
After 5 hours trying for owls last night, with one caught and a second bird seen on a hawthorn bush close to nets, it was a very cold morning as we both found out when we dropped the nets before dawn. A bit later as we did our first round, it was to what sounded like a fanfare played on toy trumpets, by players who really needed some practice. From the repeated, monotone call, we knew that a small flock of Northern Bullfinch (Stor Dompap) were moving through the site. As well as being larger in size than either of the two species found in Denmark or the UK, they also have a louder and quite distinctive call. Four individuals were captured throughout the morning, all being first year (1k) birds.

The Sparrowhawks (Spurvehøg) juveniles we are seeing now include a morph different to the rufous ones seen in September and October.

 Juvenile female Sparrowhawk (1k hun Spurvehøg) with black and white colouration.


 Rufous colouration on two different individuals for comparison.


There were a lot of recaptures today, one being TM4755, a Goldcrest (Fuglekonge) with a Swedish ring.

Flocks were again seen heading for the tip intent on making the crossing. A large flock of Barnacle Geese (Bramgås) were feeding on the beet field just north of the observatory at the end of the day. There is rain forecast for the next two days so we shall wait to see whether ringing is possible.

Good birding.

Fog stops migration for flocks, and second Perleugle (up dated)

This morning was misty and cold. A few flocks were moving overhead but several, including a flock of circa 70 Sjagger (Fieldfare) did not migrate, instead staying in the local area although rather restless. None of the finch flocks or the Sjagger (Fieldfare) were very interested in the ringing garden and during standard we had to be content with mainly Fuglekonge (Goldcrest) and Rødhals (Robin).
Once standard ringing finished we could use audiolures and just one Sjagger (Fieldfare), the third for the year, was captured. This bird has small black centres to the grey feathers on the head indicating that it is a female. A second indication is that the tail feathers are dark brown rather than black.

 1k hun Sjagger (1st year female Fieldfare)


We also tried for Grønsisken (Sisken) and Gråsisken (Redpoll), attracting both species and some Kværkefinke (Brambling).

1k han Kværkefinke (First year male Brambling). 

The yellow axillary feathers can only be seen (with difficulty) when the bird is in flight.


Our daylight ringing was completed with the capture of four Gulspurv (Yellowhammer) coming in to roost.

2k+ han Gulspurv (Adult male Yellowhammer)


We are still playing for owls most nights, but had no success last night.
We caught our second Tengmalm's Owl (Perleugle), a first year bird at 20:30 tonight.
