passagerargrupp

Passerargrupp, also known as the passenger pigeon (*Ectopistes migratorius*), was a species of pigeon that once inhabited North America in extremely large numbers. Historically, it was one of the most abundant birds on the continent, with flocks numbering in the billions during the 19th century. These birds were known for their massive, dense migrations, which could darken the sky for hours as they traveled across vast distances.

The passenger pigeon played a significant ecological role, particularly in forest regeneration. By consuming vast quantities of seeds and nuts, they dispersed nutrients across landscapes, aiding tree growth. Their presence also influenced human cultures, as they were a valuable food source for Indigenous peoples and early European settlers. However, their population began to decline rapidly in the late 19th century due to overhunting, habitat destruction, and deforestation.

By the early 20th century, the species had been driven to near extinction. The last known wild passenger pigeon was shot in Ohio in 1901, and the last captive individual, named Martha, died in the Cincinnati Zoo in September 1914. The extinction of the passenger pigeon is widely regarded as a tragic consequence of unchecked exploitation and environmental change, serving as a cautionary example of the fragility of biodiversity.

Efforts to conserve similar species today emphasize sustainable hunting practices, habitat protection, and public awareness. While the passenger pigeon remains a symbol of ecological imbalance, its story continues to be studied to better understand the factors contributing to species decline and the importance of conservation.
