In fact I saw nothing out of the normal in the forest at all. The best birds were in Maridalen itself where I had in total 3 singing Roesfinches. The only one I actually saw was a brown bird so still no fine red male. Also good numbers of Spotted Flycatchers which looked to be newly arrived and a very distant singing Wood Warbler. Whilst sitting down to listen to the Wood Warbler, a Willow Warbler with a beak full of nesting material landed only a few metres away from me. After a couple of minutes it dropped down to the ground and after it had left I was able (after a bit of searching) to discover its tiny nest on the ground hidden under some long grass.
Also in Maridalen were 3 very small Lapwing chicks with a parent which was very satisying to see as they seem to get less common each year.
