I resisted making a trip up into Maridalen last night as I couldn't bring myself to "twitch" a bird on my own patch. However, a bike ride today naturally took me though Maridalen. On the way out just after 9am there was no sound of the River Warbler but on the way back at around noon it was singing strongly as was a Marsh Warbler - who says you need to go out at night?
Not too much else to see on the trip except for Black Throated Divers on a couple of lakes. Water levels are now quite high and hopefully will stay this way such that they are able to breed succesfully although I would imagine that any nests would have been washed out over the last couple of weeks. I hope they will make second attempts.
