Submission No
473: Pin-tailed Snipe Gallinago
stenura, Broome, WA, 31st January 2004. Submitted
by: Chris Hassell.
Verdict:
Accepted
This case relates to a Pin-tailed Snipe Gallinago
stenura caught during a mist-netting exercise at the sewage treatment plant
in Broome, WA on the 31st January 2004.
The submission concentrates on measurements and the
number of tail feathers to determine the identification. The bill was 57.7mm
and the wing 131mm. Measurements overlap with Swinhoe’s Snipe (Leader &
Carey 2003). However, the bird had a shorter wing and bill than many that were
measured in Hong Kong. The moult was 0:10
indicating that it was a first year bird. The number of tail feathers (28)
clinched the identification. Pin-tailed ranges between 24–28, Swinhoe’s G. megala 18-26, Common G. gallinago 12-18
and Latham’s G. hardwickii 18. The outer 7 tail feathers were very
narrow (hence the name) with dark brown rachis and mostly brown inner and outer
vanes.Their tips were white and the inner vanes of the 4 outer feathers had
varying amounts of white.
Members agreed with the observer’s findings and voted
unanimously in
favour of acceptance. Although
other reports exist and historically the species is known to occur as a very
rare vagrant this is the first record to be accepted by BARC.
