The "passenger pigeon" was once the most prevalent bird in North America, with populations soaring to around 3 billion. They typically traveled in large flocks. Their decline began in the 19th century as they were hunted for food due to their affordability and taste. Additionally, they served as a valuable protein source and were easy to capture because of their numbers despite their fast flight. Some were killed to prevent crop damage, and their nesting habitats faced disturbances, leading them to leave forests. Over-hunting, exacerbated by technological advancements, resulted in more pigeons being killed than were being born, leading to their extinction, with the last one dying in 1914.
Lycopodium is part of a group of plants known as fern allies. They are primarily non-flowering plants characterized by their extensively branched structure, featuring small and simple, needle-like leaves that densely cover the branches and stem. In contrast, Equisetum, commonly referred to as horsetail or snake grass, resembles a horse's tail and is the sole surviving genus within the Equisetaceae family, known for vascular plants that reproduce using spores instead of seeds.
