I know it doesn't sound very likely, but an office twitch for a Lapland Bunting at Staines Reservoir last month produced an interesting aside. A female Tufted Duck there was sporting a blue 'nasal saddle'.
We've just got the details back from the scheme and the bird was ringed way back in July 2005 at Jubilan in western France. It had only been seen locally up to 12 January 2007 and then disappeared.

It's a bit surprising a bird with a big obvious saddle on its beak could go missing, but there we go! I also wonder how many of the others Lap Bunt twitchers saw and reported the bird...
