Ruddy turnstones are a common migrant on many islands including Midway.
The Pacific golden plover often flies with turnstones but is noticeably larger.
Both species nest in northern latitudes like Alaska, but winter thousands of miles south on oceanic islands and elsewhere.
Shorebirds leave their mark in their feeding and resting sites.  
The rare bristle thighed curlew is fairly common on Midway, although many continue their migration south to Tahiti and beyond.
The curlew is unusual because it feeds on the eggs of other birds at Midway.
Although very wary, they can be lured in if you imitate their peculiar "curlew" call.
