Total Length: 61 to 68 cm; Wingspan: 132 to 137 cm (Ref. 8812). Occupies the continental shelf; <300 km (Ref. 356). Ground nesting species. Nests on grassy areas or slopes. When spotting threat, adults give out alarm calls to warn chicks who respond by moving to a nearby hiding place (Ref. 87784). Displays dipping and surface-plunging behavior (Ref. 356).

Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | Eggs | Fecundity | Larvae

Laying of third egg which is variably smaller than the first two eggs in the same clutch is correlated to the facilitation of brood reduction (when beneficial) and sex-biased investment decisions, i.e., hormonally-mediated female reproductive recrudescence (Ref. 95045).
