With most having long departed for Africa, there are probably fewer than ten Garganeys left in the UK at present. I first found this one at Ravensthorpe Reservoir on 20th September and, though not reported for a couple of weeks in late September/early October, it has a poorly marked face pattern and is readily identifiable as the same individual. It was still present yesterday.
To my eyes, juvenile Garganeys stand out from the crowd of Teal – with which they often loosely associate – even when the face pattern can’t be seen. That combination of dark, oily-rust breast and flanks, contrasting sharp, whitish edges to the tertials and no white line along the outer edge of the under tail coverts is really quite eye-catching. The feeding habit of swimming around with the head partly submerged and rarely up-ending like Teals do is also a useful initial pointer.
As it’s been present for a month it will be interesting to see how long this bird stays around. Wintering birds are rare but not unheard of!
