I didn't get chance to do my hour until Monday afternoon, it wasn't the best time of day but it was better than not doing it at all!
In the end I saw 9 species, though not in great numbers -
Starling 28 (this number is a garden record)
Coal Tit 1
Blue Tit 2
Great Tit 2
House Sparrow 1
Long-tailed Tit 1 (the rest of the flock turned up about twenty minutes after the hour was up!)
A few photos taken through the window.
