Earlier this week, I then went and saw another Hume's Warbler in a park in Ghent, where it seems to be overwintering. Amazingly, though, birders looking for the Hume's Warbler also discovered a Pallas's Warbler, which seems to be overwintering in the same city park. It took me a long time to see anything, the first bird I found being a very vocal, female Firecrest, but I then heard the distant calls of the Hume's Warbler and managed to locate it. It was very mobile so I followed it to another section of the park, where a small group of birders were already watching the spritely Pallas's Warbler. This was only my third observation of this species and my first in Belgium, and it put on a great show, at times hovering so close to me I couldn't even use my binoculars. As I was enjoying that, a Goldcrest also appeared and, although I know the 'crests are no longer officially considered as warblers, I still think of them as such, thus making it a 4-warbler day in Belgian city park in late December!
