Pied Flycatcher rarity

in 32 years doing bird surveys in the forest I have never seen a Pied Flycatcher so when I stopped to look at a nice sunny corner that produced 7 Spotted Flycatchers and various warblers it was a slight shock to pick up this Pied Fly; it initially proved elusive but then took to hovering and feeding over a stony path in front of me taking small moths and the odd butterfly -- from the Birding World article I make it a first-winter and from the tail and uppertail covert colour possibly a male but sexing is said to be optimistic in first winters
