Hornborgasjon spring 2008

While on a business trip to Gothenburg, I managed a return to Hornborgasjon making this something of an annual pilgrimage for me.

The trip was a little later than last year, but the timing seemed spot on, with birds, flowers, dragonflies and butterflies all vying for attention.

I spent all of 8 hours out in the field there, but it felt like I really needed another day to do it justice. I only covered about a third of the area. The size of the place is awesome. On a sunny Sunday, I only past a handful of other birders.....yet another plus for the mighty Hornborga.


the quite thin strip of reed held the singing great reed warblers




the lake is mostly surrounded by swamp and wet grassland

I have not managed to id this plant yet - found at the edge of marshes all round the lake. Looks a bit bittercress-like


Birds of note were several singing great reed warblers, common rosefinch, calling wryneck, a small group of black tern and 100's of arctic tern, along with the regulars such as wt eagle, several osprey, 10's of rn and bn grebe, whooper swan, nesting cranes, 60+ wood sandpiper, spotted redshank, temminck's stint and flocks of raven. Surrounding woodland held pied flycatcher, and garden warbler.



No snaps of anything exotic, but the yellow wags were obliging again.



in almost everything, the swede's seem to have it sussed and do it much better than us. But they do have a goose problem that they have not yet solved - just like us.

There was a mass emergence of dragon and damselflies while I was there. They appeared to be mostly variable, azure and red-eyed damsefly, along with 4-spotted chaser, but several large white-faced darters with their bronzed wings looked stunning.

Butterflies included brimstone, comma, green hairsteak and a fast flying camberwell beauty.

The east side of the lake has limestone hillsides where the pasque flowers were almost finished this year. Not really sure if the pansy species here is mountain pansy or not amonst masses of stitchwort.
