@wathingsmecca @spurnbirdobs @RareBirdAlertUK @BirdGuides Wow! But surely it must be a Pacific with those barred flanks and limited white on breastsides?

@JamesRMcCallum1 @Arcticprince Nice find! Fits right in with the hybrids we're used to seeing in NL.
@9stan Allright, thanks Martin! Should be just a YBW then, but quite a tough nut to crack.
@9stan Thanks Martin! Any recordings available? Hume's does have a short call which can be almost identical to YBW.
@MarkFra64259515 @RareBirdAlertUK @BirdGuides Wow! How did you exclude a White Tern?
@ironfists67 Willow Warbler it is. Note the contrasting supercilium, saturated yellow colour, light underparts and long primary projection.
@SteveMcDonnell4 @PaulCave3 Thanks! Good that you took a photo. Would you mind trying to upload the observation to waarneming.nl? Would help us, local bird reviewers, a lot! Thanks in advance!
@BlaenavonNature Wow! That looks close! Congrats!
@DagChaseBirder @dutchbirding Still there today. Proves to be very reliable, following the exact same pattern every day.
@RIAllison62 There's little out of the ordinary. For UK birders Short-toed Treecreeper and Caspian Gull may be nice to see? There's also a Baikal Teal near Alkmaar and a Pygmy Cormorant near Lelystad that should be doable on the same day if you don't stay for too long with the Eider.
@bobjstinger @01000011S If you've got a car it's a 10-min ride.
Went back this morning for better views of the SPECTACLED EIDER. What. A. Bird. ~600 twitchers managed to connect, with the first foreigners from Germany and Belgium joining in. Probably a 3cy male, based on grey (not white) tertials.
@01000011S Are there more twitchers from the UK coming? I'm always available for questions and information, just drop me a message. I'll be back in the weekend as well.
@davybosman De poten zijn gefotografeerd en ongeringd.
F*ckin Spectacled Eider on Texel!! Stressful drive from Groningen, but managed to tick it in the last light. #351 (CSNA) or #341 (IOC) for my Texel list, but definitely the most memorable one yet!
@DirkStraalen Inderdaad! Ontbreken van flankvlek vond ik ook relatief makkelijk vast te stellen in het veld.
Very relaxed twitch of the 1st Pacific Diver for The Netherlands this morning! Particularly interesting how the birds' appearance changed with behaviour and distance (see the differences between both clips attached).
