History of Bird Extinctions in the 18th Century: Réunion Fody
The Réunion Fody (Foudia delloni) was a small, colorful songbird native to the island of Réunion in the Indian Ocean. This bird went extinct in the 18th century due to human activities and the introduction of invasive species.
Taxonomy
Scientific Name: Foudia delloni
Family: Ploceidae
Order: Passeriformes
Description
The Réunion Fody was a small, finch-like bird with bright red plumage on the males, while the females had duller brown or greenish hues. It had a short, conical beak adapted for eating seeds and insects. The bird was similar in size and shape to other fodies, around 12-14 cm (4.7-5.5 inches) long, with a stocky body and a short tail.
Behavior and Ecology
The Réunion Fody likely lived in forested areas and open woodlands, where it foraged for seeds, fruits, and small insects. Males were known for their vibrant red color, especially during breeding season, and would often sing to attract mates. The fody was social, living in small flocks, and played an important role in controlling insect populations and dispersing seeds across the island.
Food
The Réunion Fody’s diet consisted of seeds, fruits, and small invertebrates. Its strong beak allowed it to crack open tough seeds, and it was likely a frequent forager on the ground and in the trees.
Strength
The bird’s strength was its adaptability to different food sources, including seeds and insects, which allowed it to survive in various habitats. Its bright plumage and vocal nature made it an active participant in the island’s breeding season dynamics.
Extinction
The extinction of the Réunion Fody was primarily caused by habitat destruction and the introduction of invasive species, including rats, cats, and monkeys, which preyed on its eggs and young. Deforestation to make way for agriculture reduced its habitat, and hunting further decreased its population. By the mid-1700s, the Réunion Fody had disappeared, likely due to a combination of these factors.
