Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 23.0 cm TL male/unsexed; (Ref. 8812); max. published weight: 60.00 g (Ref. 356)
Total Length: 20 to 23 cm; Wingspan: 46 cm (Ref. 8812). In open ocean (Ref. 356). In Alaska, fluctuations of upwellings off the continental shelf near Kodiak Island causes between-season variability in laying time of this species. Egg neglect mean cumulative duration is 11 days, with the variable degree of neglect resulting in incubation range of 37 to 68 days as intermittent periods of cooling of eggs result in prolonged embryonic development (Ref. 87784). Pattering and dipping displays (Ref. 356).
