Trophic Strategy
Food Habits
The Bahamas Hutia is mostly a vegetarian. It eats bark, leaves, nuts, fruits, and the occasional insect or lizard. Geocapromys ingrahami is a good climber but tends to eat the vegetation closer to the ground.

Reproduction
Reproduction
The females breed all year round. The gestation period is 17 - 18 weeks. The female may have one to four young. The young are born full of fur and with their eyes open. They are able to eat solid foods, like leaves, a few days after they are born. The young tend to stay with their mothers for up to two years. Geocapromys ingrahami lives up to 12 years and the reproduction rate is low. Sexual maturity is two years old.

Conservation Status
Geocapromys ingarahami is an endangered species. It was once believed that it was extinct. The causes of their endangerment include hunting, habitat destruction, predation by introduced cats, dogs, and mongoose. Scientists have relocated some Hutia to other small islands of the Bahamas.
The animal is protected under the Wild Animals Protection Act of 1968. This prohibits killing and capturing of Hutia. The Bahamas Hutia has the most abundant population of all the Hutia species. One species is extinct, and all are endangered or threatened. A program is reintroducing the Bahamas Hutia to the island of Exuma.

Wikipedia
Bahamian Hutia
The Bahamian Hutia or Ingraham's Hutia (Geocapromys ingrahami) is a species of rodent in the Capromyidae family.
Geocapromys ingrahami is endemic to the Bahamas.
Contents |
Habitat
Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical dry shrubland, and rocky areas. It is a nocturnal species, remaining underground during the day. It is threatened due to land clearance.
Extinctions
Two subspecies became extinct in modern times. The Crooked Island Hutia (G. i. irrectus) and the Great Abaco Hutia (G. i. abaconis) were mentioned by early European voyagers, and are thought to have become extinct by 1600. This is thought to be due to land clearance rather than direct hunting.
