Southern right whales have begun arriving at Puerto Pirámides in Argentine Patagonia as the annual migration season begins [1].
These migrations are critical for the species' survival, as the protected waters of the Península Valdés coastal zone provide a safe environment for whales to reproduce and give birth to their calves [2].
The arrival of the first specimens typically occurs in April [1]. The full whale-watching season extends from April through December [1], with the highest levels of activity and the majority of births occurring between June and August [1, 2].
Local estimates place the population of southern right whales in the region at more than 2,300 individuals [1]. The species is characterized by significant size, with some whales reaching weights of up to 40 tons [1].
Physical dimensions vary by gender and age. Females can grow up to 16 meters in length, while males typically range between 13 and 14 meters [1]. Calves are considerably smaller, measuring between three and five meters at birth [1].
The concentration of these mammals in the Península Valdés area makes the region a primary hub for marine research and ecotourism, providing a rare opportunity to observe the breeding cycle of these massive creatures in their natural habitat [2].

The predictable return of the southern right whale to the Península Valdés highlights the ecological importance of protected coastal zones. By providing a sanctuary for calving and reproduction, these waters support the population stability of a species that reaches weights of 40 tons, while simultaneously driving the regional economy through seasonal ecotourism.
