The first record of Alder Flycatcher (an American Empidonax flycatcher species) for the UK. Present in Nanjizal Valley in West Cornwall for 2 days in October 2008. Yet another bird present in mid-week causing problems for those birders with jobs!
This species is almost impossible to separate in the field from its close relative Willow Flycatcher, indeed they were, up until recently, considered the same species, Traill's Flycatcher. Indeed some US birders still use this name for these two species. Fortunately this bird was trapped and ringed and identified in the hand.
In the field this bird did show some features, such as a thin eye ring which is thought may point to its identity as Alder.
