Occurrence Remarks The documentation form by Peter Ernzen is the only one submitted and forms the basis of this record. Other observers include Joshua Ernzen. | Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". | The original documentation form event lasted from 19:50:00/20:00:00.
Occurrence Status present
Field Number 1995-14
Event Remarks Viewing Conditions: [...] The sky was overcast, but sufficient lighting existed to identify numerous dunlins and sanderlings that were present on the Southeast mudflat. Scanning to the north mudflat with my Bushnell 7 x 35 binoculars, [...] While in flight the bird was about 25 - 50 feet in the air. The bird was any where from 300 to 100 feet from me - distance is estimated. When the bird flew away, it flew directly over me.
