| Occurrence Remarks |
The documentation form by Carl J. Bendorf forms the basis of this record. Another documentation form by Thomas J. Staudt was submitted. | Elimination of similar species: The obvious possibilities are both Common or Forsters' Terns. At the very most, this bird was perhaps half the size of the gulls. This would put the body length in the general range of 8" long with a wingspread of 24" (according to size of Ring bills in the Natl. Geo. Guide) The Natl. Geo. Guide gives the general size range of Least Tern as 9" long with a wingspread of 20 ". The sizes of the other terns are given as Common L 14 1/2', W 30", and Forsters' L 14 1/2, W=31". Thus on size alone, Least Tern seems to be the only reasonable choice. The short but deeply forked tail also indicates Least Tern. Harrison's SEABIRDS says, on page 182, "Size and hurried flight,..., usually sufficient to clinch identification in northern hemisphere". The flight of this bird was much quicker and fluttery compared to my experience with the slower, deeper, and more deliberate flight of Common and Forster's Terns. | The original documentation form event lasted from 09:30:00/09:32:00. |
