This morning, after struggling through incredibly thick mud, I reached a huddle of birders all looking at a small Robin-sized bird with a faint blue crescent on its breast feeding on the edge of a large reedbed. It was a male Bluethroat, a fantastic record for the time of year and for Sussex.
The bird was first seen last Sunday at West Rise Marsh in Eastbourne and identified from photos on Tuesday. Luckily it stayed around and has since allowed many Sussex and national birders to see it although it has been elusive. Unusually for me, it was not as elusive when I went to see it as I immediately had it in my binocular view after arriving. Much better than standing around for hours in the biting wind which some birders have had to do over the past week!
It appears to be a White-spotted Bluethroat, one of two subspecies of Bluethroat that have been recorded in the UK. It seems to be the less frequent subspecies, with the Red-spotted Bluethroat being the other that sometimes reaches our shores. Due to the difference in latitude of the two subspecies’ breeding ground, they typically arrive at different times of year. The White-spotted is most commonly found in late March and April whereas the Red-spotted is more likely to be found in May. Although White-spotted is the earlier arriver, it is more likely that this bird has been wintering in the UK, rather than having overshot its breeding grounds on its spring migration.
Occasions of Bluethroats wintering in the UK are occasionally recorded, for example last year a bird was found in February in Lincolnshire which remained until the end of March. Presumably it then attempted to migrate to where it thinks its breeding grounds are. It will be interesting to see if this Eastbourne bird stays much longer and whether it tries to set up a territory here or flies elsewhere to breed.
Fantastically, this is not the first Sussex rarity that Eastbourne has had to offer this winter. Black Guillemots, although they breed on remote islands in the north of England, are even rarer in Sussex than Bluethroats, so for one to turn up in Eastbourne’s Sovereign Harbour was quite special. It has been present since late November, although I waited until the New Year before going along to see it. It’s a wonderfully confiding bird in a great setting!
