– very long legs, in limosa the feet and a part of the tarsus protrude the tail
– in BREED breast, neck and head rusty brown, distincly paler than in islandica

Black-tailed Godwit Limosa l. limosa, AD BREED
BIF3075, 02/06/2017, Ochsenmoor, Germany, Kai Bratke
same as BIF3074
valid for all ssp.:

Black-tailed Godwit Limosa limosa islandica, AD BREED
BIF3014, 04/06/2019, Snæfellsness, Iceland, Patrick Franke
distinctly differentiated from BREED mainland WP ssp. limosa by:
– rich chestnut coloured on head, neck and breast
– on average shorter-bill
– shorter legs

Black-tailed Godwit Limosa limosa islandica, AD BREED
BIF3015, 01/06/2019, Myvatn, Iceland, Patrick Franke

Black-tailed GodwitLimosa limosa islandica, AD BREED
BIF3017, 29/05/2019, Langanes, Iceland, Patrick Franke
– no white wedge on the lower back → Bar-tailed Godwit

Black-tailed Godwit Limosa limosa islandica, AD BREED possibly M and F
BIF3020, 29/05/2019, Langanes, Iceland, Patrick Franke

Black-tailed Godwit Limosa limosa islandica, AD BREED possibly M and F
BIF3018, 29/05/2019, Langanes, Iceland, Patrick Franke
– in ssp. islandica only the feet protrude the tail (compare with ssp. limosa on BIF3075)

Black-tailed Godwit Limosa l. limosa
BIF3026, 29/06/2010, Kiskunság National Park, Hungary, Mathias Putze

– moult in limosa starts earlier than in islandica

Black-tailed Godwit Limosa l. limosa
BIF3028, 29/06/2010, Kiskunság National Park, Hungary, Mathias Putze
– at greater distance the black and white wing pattern is a giveaway

Black-tailed Godwit Limosa l. limosa
BIF3027, 11/02/2015, Ras Al Kabbah, Oman, Mathias Putze
– NBREED plain grey upperside, head and breast

Black-tailed Godwit Limosa limosa melanuroides, 1CY

Sharp-tailed Sandpiper Calidris acuminata, AD BREED
BIF3078, 10/08/2019, Gun Galuut, Mongolia, Andreas Buchheim

BIF3079, 10/08/2019, Gun Galuut, Mongolia, Andreas Buchheim
– striking wing pattern
– much longer legs than Bar-tailed Godwit

>> ACOUSTIC ID >>>>>

– during migration usually single or series of short downslurs
– monophonic with inharmonic partials
– squeaky, a bit toy-like timbre reminding of Bar-tailed Godwit due to similar inharmonic partials, but at a lower frequency band and different call structure
– elements variable in length
– sometimes elements are linked, thus might appear as one broad modulated call in spectrograms

>> ACOUSTIC ID >>>>>

– most common on migration are single or fast series of dissimilar elements
– calls usually consist of noise parts and slightly modulated elements with harmonic partials
– clear, screechy or scratchy impression – depending on the length and quality of the calls
– series of calls may resemble Dunlin or Curlew Sandpiper – especially at greater distance or under bad acoustic circumstances
