Could this winter Redstart be an Ehrenberg's?

The intriguing 1cy male Common Redstart was still present today on December 15, 2014 along the south side of Vesteroe Harbour on Laesoe in Denmark. The bird shows some features (pale wing panel and whitish washed feather tips to the underparts) that may indicate the subspecies P. p. samamisicus (Ehrenberg's Redstart). However identification of this race in 1cy plumage is still in its infancy and unfortunately the bird has not been heard calling. Several faecal samples have been collected today as faecal samples from a target species can contain epithelial cells from its digestive tract walls and I thus hope to have these samples tested for DNA.
