So few of these birds remained that their genetic diversity is a problem for reproducing the species 😕.
“inbreeding depression is a significant problem.[29] The recovery efforts are hampered especially by low fertility of the remaining birds. Genetic analyses have been employed to select captive breeding stock in an effort to preserve the maximum genetic diversity.”
This is a problem with cheetahs as well, where it’s theorized that only a small group survived the last ice age, and survived thru inbreeding. Because of this, they are essentially genetic “clones” of one another with almost zero genetic variability, and they have about a 50% chance to successfully receive transplants without the need for the medication typically required to prevent rejection.

Do cheetahs seem pretty healthy overall as a species even with low diversity?
