The Scientific Use Area under Special Protection Cormorant and Justicia Islands was created in 1990 under provincial jurisdiction. The purpose of its creation is the protection and conservation of the different species, both birds and cetaceans, found in the area.

In Justicia Island, also known as Isla de los Pájaros, nest the imperial cormorant, the black-necked cormorant or rock cormorant, the biguá, the gull, the gull, the southern gull and the swallow tern, among other birds. It is a place of geomorphological and paleontological interest due to the large amount of mega and microfossils found in tertiary deposits and the presence of the remains of a Jurassic petrified forest. The island is also a site of historical and cultural importance. One of the mutineers during the voyage of Hernando de Magallanes in 1520 was executed there. It was also visited by prominent people such as Fitz Roy and Charles Darwin.

On Cormorant Island, also known as Penguin Island, there are different birds such as the biguá, the Antarctic pigeon, the black oystercatcher and gulls and terns, among others. It stands out for a colony of more than 120,000 individuals of the Magellanic penguin.

Among the islands, it is common to observe the Commerson’s dolphin, which uses the surrounding waters as a breeding site.
