It digs a small hollow with its feet and gathers grass and other material into it to make a nest, and the male and female take turns keeping the eggs warm.
How the Black-tailed gull lives
They eat fish and bristle worms at the sea surface, and crabs on sandy beaches. They rest on sandy beaches and sea walls. Chicks spend time nestled against their parents to keep warm. In summer, the grown chicks begin practicing flight.

We check each fact against its source. The illustrations simplify how the real animal looks.
The classification (class, order, family, genus) follows Wikidata records, checked against GBIF. Classifications can change as research goes on.
The basic data are the values given in each source. They vary with how the animal is measured, whether it is male or female, and whether it lives in the wild or in captivity.
The conservation status in Japan is the category in the Red Lists of the Ministry of the Environment of Japan, which assess the risk of extinction for wild animals in Japan.
