Ectopistes (2,5 million years ago – up to 1914 year)

What does the name mean: The Latin genus name Ectopistes comes from the Ancient Greek words ek (“away”) and topos (“place”), and is also associated with the verb ektopizō — “to move about” or “to wander.” Literally, it means “wanderer” or “migrant.” The species epithet migratorius (Latin for “migrating”) essentially repeats this meaning: both elements of the binomial name refer to the bird’s migratory lifestyle. The English common name, “passenger pigeon,” also reflects this characteristic.

The passenger pigeon (Ectopistes migratorius) was an extinct bird species once among the most numerous birds in North America. Before its extinction in the early 20th century, these birds inhabited deciduous forests from the Great Plains to the Atlantic coast. Their disappearance is regarded as a classic example of human impact on natural ecosystems. Fossil remains of passenger pigeons dating to the Quaternary Period (beginning about 2.5 million years ago) have been discovered, among other places, in North Carolina. For a long time, the species played an important role in forest ecosystems, contributing to seed dispersal and forest regeneration.

Adult male passenger pigeons were slightly larger than females and reached lengths of about 40 cm. The upper body was bluish-gray, becoming paler on the underside. A characteristic feature was the iridescent bronze, purple, or golden-green feathers on the neck, which were used in courtship displays. Females were smaller and duller in coloration, lacking pronounced iridescence.

Passenger pigeons were highly adapted for flight. Their long pointed wings and wedge-shaped tail allowed them to reach speeds of up to 100 km/h and travel great distances during seasonal migrations. Movements of more than 500 km per day are known. These birds lived socially, forming enormous flocks that could number in the millions. Nesting took place in dense forests; sometimes up to 100 nests were located in a single tree. Their diet consisted mainly of tree seeds, as well as nuts, berries, and insects.

Mass hunting and destruction of natural habitats during the 19th century led to a rapid population decline. Despite conservation attempts, the last wild passenger pigeon was killed in 1900. The final known individual — a female named Martha — died at the Cincinnati Zoo in 1914.

The history of the passenger pigeon is regarded as an important example of species extinction caused by human activity. It highlights the importance of preserving biodiversity and maintaining the stability of natural ecosystems.
