Kozue Shiomi (Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, Sendai, Japan) reports open access in the journal Ecology on a rare case that implies the upper limit of a seabird’s capacity to tolerate a storm.  A GPS-equipped Streaked Shearwater Calonectris leucomelas (Near Threatened) was caught in and survived a huge typhoon, showing swirling flight high (up to 4.7 km altitude) at speeds of 80-170 km/h for 11 hours over the mainland of Japan.

The paper concludes:

“The present study appears to demonstrate an example of the behavior of seabirds at the extreme edge between failure and success of survival during a storm.  Further accumulation of such data would contribute toward an understanding of whether and how seabirds manage to survive frequent but irregular weather events.”
