The hunt for a Yellow-browed Warbler

I am on a mission this autumn to find a Yellow-browed Warbler on my patch. Surprisingly (perhaps) there are fewer records of these Siberian waifs in Denmark than in the UK but they must pass through in reasonable numbers undetected. A handful of records each year from the western tip of Denmark (Blåvand) and the odd one scattered elsewhere are all that turn up in the average year. My patch has some potential YBW habitat so I was out checking it this morning. Sadly no luck this time but highlights were a Merlin, several 'eastern chiffchaffs' giving the two-tone downward inflected call, a couple of Crossbills, a few Goldcrest, a late Pied Flycatcher and a good passage of Meadow Pipits moving south-west. Bit cooler today - almost needed gloves for the first time this autumn...
