Abstract

The author makes the following corrections: In line 19 of "2.3. Penguin feather" on page 3, “an average inner diameter of 11 ± 4 mm” should be changed to “an average inner diameter of 11 ± 4 μm”. In the note to Fig. 4g, “the average values of 11 ± 4 mm” should be changed to “the average values of 11 ± 4 μm”. The original article has been corrected.
