Comments: alarm call.   This 11 second recording documents 14 alarm vocalizations of an adult Spotted Sandpiper. There appear to be two variants in this recording. The first type is a higher pitched squared-off note that peaks at approx 4.5kHz. The second type is a lower pitched smooth arch-shaped note which peaks at approx 3.5kHz. Both notes have a similarity to the call of a Pygmy Nuthatch. This vocalist was perched on driftwood on a beach. And was alert to and seemed agitated by my presence. There may have been eggs/young in the area but this bird did not perform a broken-wing act as I wandered around. However I did note a second Spotted Sandpiper silently scurry away. This is an unedited and unmodified recording of the natural spacing of this bird’s utterances.     This could be the call that the BNA calls the alarm call. The BNA account described it thus: Alarm Calls. Consist of weet weet and peet peet peet and are given on the ground or in flight. When flushed, typical call is an extended series of the same notes: tweet-weet-tweet-weet-weettweet-weet-weet-weet-weet (Smith 1914, Stone 1937, Knowles 1942). When alarmed by an intruder, call changes to metallic spink spink if chicks present (Stone 1937), a louder version of Pink Call (see below).     Additional details regarding context may be found at: http://ebird.org/ebird/view/checklist?subID=S24148474     This recording was made with an iPhone 5s with stock microphone and Røde Rec application.     bird-seen:yes   Citation: Elias Aristides Elias, XC255373.
