Oostende and Zeebrugge

An afternoon visit to both breeding colonies of Oostende and Zeebrugge today, with a total of 43 rings! Many of these were juvenile birds, some of them not yet able to fly. Now I hope to see some of the young birds of today later on in autumn/winter! Sadly, also several dead birds, most of them because of traffic... Three of the dead juvenile birds were ringed, of which one with a colour-ring.

Vlissingen-Oost

Last weekend I went to Vlissingen-Oost, where Roland-Jan Buijs has ringed many gulls in the previous years (and also some young birds this year), in order to see some of these birds. Not as succesfull as last year in May (when I read >80 rings), but I was happy with every ring I could read. In the nearby port I could read some Oystercatchers too, and a Belgian-ringed Herring (metal ring) was at Westkapelle.

Wing-tagged Marsh-harriers in Belgium

This year, the Research Institute for Nature and Forest (INBO) has started a research project on Marsh harriers Circus aeroginosus in Belgium, and adjacent areas in the Netherlands. For this project, young birds are ringed and wing-tagged on the nest. Until now about 55 birds have been tagged, and the expections are that we will end at 65 - 70 birds for this first year. As I am participating in this project, some pictures can be found below. More info about the project can be found at
http://www.inbo.be/content/page.asp?pid=FAU_VO_BruineKiekendief

Each bird has one tag on each wing, with different tags on the left and right wing. The colours used are white, yellow, orange, purple, red, green and blue, and the symbols (which can be black or white) are X, -, I, /, 0, 8, a full dot and a triangle. Some tags have no symbol.

The first birds have already left their nests, and are flying around, so keep your eyes open for these birds! It will be very interesting to see if some will be recored in southern Europe this winter.

Colony of Zeebrugge

Last week I did 2 attempts to see Belgium's 3rd King eider, in which I unfortunately did not succeed. Since I was in the harbour of Zeebrugge, where our largest colony of large gulls is located I tried to read some rings and take some pictures. All birds seen were locally-ringed.
