Red-throated Loons overwinter in large numbers on the Western European coast. On Texel you can sometimes see hundreds of birds fly by on a sunny winter's day. Regularly the much scarier Black-throated Loon is also seen, but often no more than one or a few birds. Both species breed in Northern Europe from Scotland to Russia. Good places to spot them are the harbors of Oudeschild and the NIOZ.
