This is a very interesting post. It has lead me to do some more research into this and the small production numbers is mainly due to the slow reproduction. Cahows only mate once a year and incubation periods are approximately 51 days. Another thing is, this endangered species which lives on the small islets where there isn't much soil, making it difficult to burrow. They will also be further affected by the erosion due to rises in sea levels and global warming. Just a little thing I learnt after reading this. Thanks for sharing.
