Willow Warbler (Phylloscopus trochilus)

OTHER NAMES: Willow Wren

Adult Willow Warbler (subspecies P. t. trochilus) at Brent Reservoir, London - August 2010

One of the commoner warblers in the UK, it can be found in woodland most commonly. As with most warblers however it is prone to flit in and out of cover which can make it harder to photograph. As with most things some populations will be much more skittish than others. The hardest challenge with Willow Warblers is differentiating them from the very similar looking Chiffchaff, to the point where it is best done through their different songs.
