Gulirisk, 12. maj 2017, Gjerrild Nordstrand Øst

En rigtig fin morgen med trækkende Gulirisk ved Gjerrild Nordstrand Øst, hvor blev til tre forskellige trækkende øst.

Dagens tredje fugl:

Kom trækkende i modlys og blev derfor ikke fotograferet. Heldigvis fangede den digitale lydoptager kaldet idet den passerede forbi obsposten.

Hærfugl, 13. maj 2017, Gjerrild Nordstrand Øst

Hærfuglen blev fundet af Lars Keller, hvor den sås trække øst over havet ret tæt på kysten, trak ind ved klinten og gik til rast ved den lille hytte øverst på klinten, hvorfra den fortsatte videre ind i landet i retning mod Gjerrild Fyr.

Jeg fandt min første Hærfugl på præcis samme dato og præcis 30 år siden, nemlig på min fødselsdag den 13. maj 1987 på Læsø.

Trak ind ved klinten, hvor den gik til rast ved hytten. Her ses den krydse ind over stranden.©: Kent Olsen.

Dette er det sidste billeder i serien, men anbragt øverst som appetitvækker for en super dejlig fugl. Billederne herunder kommer i kronologisk rækkefølge. ©: Kent Olsen



Fuglen kom trækkende til øst fra og landede på stranden i nogle minutter sammen med to Hvide Vipstjerter. ©: Kent Olsen

Fuglen blev siddende på stranden i to minutter inden den fløj lidt længere mod vest. ©: Kent Olsen

Efter rast på stranden trak den lige ind over obsposten. ©: Kent Olsen

Forsatte videre mod vest, men gik ned igen ved bækken vest for obsposten. ©: Kent Olsen



Rastede nogle flere minutter ved bækken inden den fløj ind i den nordøstligste sommerhushave, der kort efter blev gennemfløjet af en Spurvehøg. Hortulanen sås ikke igen er formentlig trukket videre mod vest. ©: Kent Olsen

Cat somewhat similar til Wildcat in Białowieża



During a spotlighting session in the Białowieża Forest on March 3, 2017, we found a cat with phenotypic characteristics similar to European Wildcat Felis silvestris, at least somewhat similar to individuals seen in northeast France earlier.

According to IUCN, the Polish wildcat population forms a continuum with Slovakian and Ukrainian populations and the current Carpathian population, mainly found along the borders with Slovakia and Ukraine, constitute the current northernmost distribution in Poland. Wildcat used to have a population in Białowieża, but is believed to have gone extinct.

We acknowledge that domestic cats may appear very similar to Wildcats and we are not claiming that we have seen a European wildcat in Białowieża. Nevertheless, we found our sighting sufficiently interesting and decided to distribute the photos so that other mammal watchers can have it in their mind when visiting the area. We will see what the future brings. Recolonization has already occurred in Belgium, Czech Republic and Slovakia, France, Germany, and Switzerland.

Please feel free to comment on the subject or the photos.


The tail was bushy with clearly divided black rings around the tail (the tip of the tail being completely black).

Possible Siberian Accentor (Prunella montanella), 13.11.2016, Glatved Beach, Norddjurs, Denmark

Today was my second day searching for Siberian Accentor at Glatved Beach on Djursland. The habitat is indeed very similar to other places in Scandinavia from where sightings have been reported during this massive influx. After one hour of using playback of Siberian Accentor call, there was a bird responding with the right tone to its call. There had been several Dunnocks responding to the playback, but this one was different. I immediately stopped using playback and began recording instead (two of the best recordings are available here and further down).

The bird was calling from within dense bushes and was not visible. After several minutes of waiting without anything happening I used playback once again. This made a bird fly from the busk from where the putative Siberian Accentor call was heard; the flying bird was less than twenty meters away and looked like a Siberian Accentor with obvious black mask and broad yellow eyebrow and yellowish underside. However, even though it was seen in bright sunlight it was only seen very briefly and without binoculars. When it dropped down it was immediately gone as it went streight into another very dense bush.

I waited from almost half an hour without it showing itself again. Then I went closer and eventually ended up standing few meters from where the bird had dropped into the bush. I suddenly flushed a bird which went out on the other side of the bush and flew further away into an even much larger thicket. In this second sighting I only managed to see that it was a Donnock-type with a streaked reddish-brown back. Unfortunately it was not seen or heard again even though I waited until after sunset.

As the two sightings were only very brief, the only documentation that I have is the two recordings below. However, I am not sure that a positive ID can be made based on sound recordings alone. I will search for the bird tomorrow as I hope to be able to document the record with photos.

The best recording of the call are these two: XC342620 and XC342622.

Eastern Black Redstart (Phoenicurus ochruros phoenicuroides) on Djursland

1st winter male Eastern Black Redstart, Boennerup Harbour, Djursland, Denmark, 05.11.2016.

On 5 November 2016, a first-winter male Eastern Black Redstart Phoenicurus ochruros phoenicuroides was observed at Boennerup Harbour, Jutland, Denmark. It was actively feeding on and along the granite blocks bordering the harbour. It has turned out that it had already been present and photographed (photo unfortunately deleted) on 25 October when it was considered to be a late Common Redstart P. phoenicurus by the finder and local bird photographer John Mortensen who also managed to relocated the bird yesterday on 4 November. After the first photos were published on Facebook, it was re-identified as an Eastern Black Redstart.

Eastern Black Redstart is a long distance migrant from its central Asian breeding grounds to wintering areas in central India west to northeast Africa. Its breeding and wintering distribution is comparable to species that occur regularly in northwest Europe, including Desert Wheatear and Isabelline Shrike (Slack 2009).

When encountering an Eastern Black Redstart the possibility of a hybrid needs to be ruled out. The best way to assess if the bird is a hybrid is to take a look at the wing formula. Steijn (2005) proposed differences based upon the emarginations on p3-6 for phoenicuroides and a ratio for spacing between p5-6 and p6-7. The set of photos below provides a good indication that the bird in question is not a hybrid

There is an interesting paper on the taxonomy of Black Redstarts by Ertan (2006) which concluded that Eastern Black Redstart, phoenicuroides (and rufiventris) were the most divergent subspecies in the Black Redstart complex, and that they appear to be more closely related to Hodgson’s Redstart P. hodgsoni than Western Black Redstart gibraltariensis (and aterrimus) and as such may warrant full species status. Steijn (2005) also suggested there might be merit in treating phoenicuroides (and rufiventris) as a separate species. This is also reported in Slack (2009).

In summary, this very smart, distinctive bird represents potentially the first record of Eastern Black Redstart in Denmark.

1st winter male Eastern Black Redstart, Boennerup Harbour, Djursland, Denmark, 05.11.2016. The wing formula looks spot on for (Eastern) Black Redstart. Some hybrids Redstart X Black Redstart have wing formula closer to Common Redstart.

1st winter male Eastern Black Redstart, Boennerup Harbour, Djursland, Denmark, 05.11.2016. The Eastern Black Redstart can be aged as a 1cy bird due to the pattern on the outer tail feather which has a dark patch on the outer webm a pattern which lacks in adult plumage, and due to the colour of the feather shaft tip which is black in a larger extent than in adult males.

As seen in the photos the lower belly is cream/whitish, a character shared with hybrids Redstart X Black Redstart which have quiet extensive white here - male Common Redstart character. However on checking the character on live DNA-tested birds, it seems normal for young male phoenicuroides to have a white patch between the legs.


1st winter male Common Redstart, Vesteroe Harbour, Laesoe, Denmark, December 2014. It is shown her for comparison with the Eastern Black Redstart. Note the differences in wing formula where there is no emargination on p6 and were the spacing ratio p5-6:p6-7 = 1:1 in the Common Redstart.

Sortstrubet Bynkefugl, 21.10.2016, Anholt

blev fundet i regnvejr og hård vind, så den var meget svær at arbejde med. Virkede langvinget i felten, og muligheden for en mørk stejnegeri gjorde, at vi brugte ekstra tid på den.
