Alcids ‘fly’ at efficient Strouhal numbers in both air and water but vary stroke velocity and angle

Birds that use their wings for ‘flight’ in both air and water are expected to fly poorly in each fluid relative to single-fluid specialists; that is, these jacks-of-all-trades should be the masters of none.
