Getting better
Today started with less wind and high cloud. Birds calling from the bushes as it got light. We had more variety today with a Reed Warbler, Garden Warbler and 13 Dunnocks. A sign of an increase in migration were the 13 Dunnocks that we caught.
There was a strong movement of raptors throughout the day and we caught 5 Sparrowhawks in the raptor nets. Follow the migration watch at Gedser Odde on the Træk pages from the home page.
Here are todays slightly better results.
Spurvehøg 5
Jernspurv 13
Sangdrossel 1
Rørsanger 1
Havesanger 1
Munk 2
Gransanger 5
Løvsanger 2
Bogfinke 1
Tomorrow the wind is forecast to move round to the North West. Much better for migration. But the wind speed may be too high to erect all of the nets. I think we will have to consider what to do in the morning.

Windy and wet
Today was a very sad day, we had to say a fond goodbye to our resident Dane.
But, the very windy weather kept any birds low in the bushes, we could only manage 102 net metres, with nets in the more secluded rides. Several rain storms passed over after we had finished the standard netting.
Here are todays totals:-
Rødhals/Robin 1/1
Gransanger/Chiffchaff 2/0
Blackbird 0/1
Great Tit 0/1
Cups of Coffee 10+ (some of the subspecies med mælk)
Jimmy, our new resident Dane, had an excellent day at the tip with, as well as others:-
1900+ Swallows
220 Kestrels
550 Eiders.
Many thanks to Jimmy and his company over evening meal (and Dr Nielsen's)
Here is today's little joke for you, especially for our departed Dane:-
How many therapists does it take to change a light bulb?
One, but the light bulb must want to change.
Hilsen, Ta-ta etc.
Wind
Today we woke with great hopes and the knowledge that it is the first day of the rest of our lives.
But it was like groundhog day.
The wind was stronger than yesterday.
Here are todays totals:-
Spurvehøg 1
Rødhals 1
Rødstjert 3
Munk 1/1
Gransanger 3
Grå Flueshapper 1
Broget Fluesnapper 1
Blåmejse 0/1
Of the observations at the point were 640 Scoter, 142 Wigeon and 94 Eider. Overhead were 120 Swallows. The observers do a magnificent job out at the point, they are there in all weathers. Today well over 1000 individual birds have been counted of over 30 species. We ringers are comparative softies, being able to shelter inside and have a fresh cup of coffee whenever we want. I'd like to salute our trækers.
The weather is forecast to change on Sunday evening to a northerly wind. The winds from the south-west have been stopping the migration. Somewhere there are birds waiting to come to Gedser next week. Or was that a dream I have just had?
The poet is too depressed today for his ditty and the photographer is fast asleep in bed, so there are no images. Our colonial colleague is "discussing" a point with a friend of GFU on the interweb thing. A point I fear will run and run. Knowing both parties I am backing the Danish team.
Here is a poor English joke.
What do you call a deer with no eyes?
No idea.

More of the same
Another quiet day with sunshine and a westerly wind that made us delay opening the nets for an hour.
Our Five Star accomadation taken a few years ago. The observant of you will have seen that it was taken before the alterations. Especially for those of you who have never visited Gedser.
Here are todays birds:-
Sparrowhawk 1
Robin 5/1
Redstart 1
Blackcap 2
Great Tit 1
Blue Tit 0/1
Blackbird 0/1
Luckily around 14:00 we caught a female Sparrowhawk in the raptor nets.
No pictures of birds today, so an image taken a couple of years ago of Gedser´s main street just after the stage coach has left.
Here is todays little ditty:-
There were thre men in a fuglestation, They each came from a different nation, From Canada, England and Denmark, Like brothers they made their mark, Despite being no relation.
Another quiet day at the observatory

I was a little bored, so here is a little limerick to go to bed on:-
hundredevis af fugle - fløj over haven i dag
Trækket på Odden var ikke imponerende: de største tal stod Sortand/ Black Scooter (330) for sammen med Landsvale / Swallow (200) og Bogfinke / Chaffinch (300).
Rainer Ebel fra Canada har igen i dag et indlæg om fangsterne her på Gedser Fuglestation - her Kommer det:
Migration Blues
September’s newly ringed birds are compared between last year and this year (See graph).
For the most part, both years reflect each other at least until 14 September. But this year, from the 7th to the 11th we almost discovered the abyss of the Marianna Trench The 10th, 13th, and 16th represents an off phase oscillation. What it means is anyone’s guess. With missing data and weather data not at the finger tips for 2017 it is impossible to compare. Thereafter numbers of netted birds increased reaching the ultimate peak of 358 netted birds on the 18th . What happened?
This year we just managed to bump along, our nets sitting essentially empty, waving to the birds flying overhead. We did everything within our power short of the mystic Canadian rain dance that appears not to work in Denmark. But do blame our lack lust performance on the wind or more generally, on atmospheric conditions of the day.
Vi havde i dag besøg af 3 Nøddekriger, der kredsede over haven en tid og samtidig havde vi også besøg af Lars Peter Bærendsen fra Næstved. Han var kommet for at fotografere Duehaler i vores sommerfuglebusk.
Vi var så heldige at han fik taget et foto af den ene Nøddekrige og heldigvis også fik Duehalen i kassen.

What ? another day of nothing ??
I dag var en almindelig gennemsnitlig dag, hvad angår trækket. På stationen var vi noget skuffede over antallet af fangne fugle. Flere forskellige arter passerede haven højt, der i blandt Bogfinker og Korsnæb.
Vi haved en flot solnedgang over Østersøen til aften:
Rainer Ebel has some comments on Eurasian Sparrowhawk (Spurvehøg) sex ratios netted at Gedser Birdstation:
We were curious as to how effective the “raptor nets” were at capturing both sexes of the Eurasian Sparrowhawk at the station. Upon reviewing the capture data from April, August, September, October, and November 2016 to 2018 there were 96 males and 54 females captured. This represents a male to female ratio of 16:9 suggesting that the 55mm on the diagonal favours the capture of the smaller male over the larger female. To compensate for this differential capture the use of a larger mesh with the similar thread size of the existing nets should be used.
Eight nets set in a pattern of four inner and 4 outer 10metre nets would be ideal for the garden site. A more even sex ratio capture would be more representative of the migrating sparrowhawks we witness flying over the station.

En dag med fugle i haven
Natten var præget af vind fra Nordvest og den bragte fugle til Gedser Fuglestation. Rødhalsen dominerede totalt med næsten halvdelen af fangsterne.
Ude på Spidsen var det Bogfinkerne (Chaffinch) som dominerede småfugletrækket med næsten 1500 fugle.
Rødstjert (Redstart) 1k han bemærk de lyse spidser, som slides af i vinterens læb, så denne han til foråret fremstår med et flot orange bryst.

Emty nets ?
The migration at Gedser Odde was dominated by 48 Honey Buzzards, 41 Sparrowhawks, 28 Kestrels, 2 Hobby's and one Pallid Harrier. Of passerines they counted among others 360 Swallows. Over the Garden we observed large numbers of passerines. These birds were present all day.
The bird on the graph is a Willow Warbler, as we did not have a useful image of a Chiffchaff. However, you will notice that the numbers of Willow Warblers has decreased since the 1. September, as illustrated by the black trend line. The Chiffchaffs have moved in, and the blue trend line suggests that we can expect more Chiffchaffs in the days to come.
Strong wind all day and the rain came through about 4 o'clock and the wind dropped. Suddently we saw a Nutcracker in the garden, and luckily we found it in the high net on our normal net round. Measurements indicated that it was a thick-billed Nutcracker ssp caryocatactes.

Quiet day with lots of sun and fresh wind from the southwest
The small numbers in the morning faded at about 8.30 o'clock. The highest number was Chiffchaff (8) with the Robin (7 + 2) in second place.
There are 3 peaks in the movements at Gedser. The low numbers occured because of the "bad" weather from the 8th to 11th of September. The last lower peak suggests that the migration of the Robin is fading, but we know by previous experience that the Migration is at its beginning.
At the Tip 145 Black Scoter and 660 Barn Swallows was the most numerous. At 10 o'clock a Black Kite passed by and later a single Osprey. The 46 outgoing Sparrowhawks we did not noticed much of at the ringing station.
