Scientific Reports 6: Article number: 38154 ; published online: 30 November 2016; updated: 28 April 2017

The original version of this Article contained an error. The authors reported the maximum flight speed of Whimbrels (Numenius phaeopus) as the fastest recorded for shorebirds flying over the ocean, but this was not the case.

As a result, in the Abstract,

“Using geolocators to track the migration of Icelandic whimbrels (Numenius phaeopus), we show that they can complete a round-trip of 11,000 km making two non-stop sea crossings and flying at speeds of up to 24 m s−1; the fastest recorded for shorebirds flying over the ocean”.

now reads:

In the Results and Discussion section,

“During the post-nuptial migration in autumn 2012, all four whimbrels flew non-stop to their wintering areas in west Africa (Fig. 2), covering distances of ~3900 to 5500 km in 5 days (Table 1) and, on occasion, achieving the fastest recorded speeds for terrestrial birds on long-distance flight over oceanic waters (up to 18–24 m s−1)”.
