Before introduction of invasive predators, monitor lizards & raptors main predators of adults w/ crows taking young. Accidentally introduced brown tree snakes from S Pacific have taken disastrous toll on these birds as well as cats, rats, & pigs.
Became extinct in wild in late 1980s due to introduced predators (especially brown tree snakes but also cats/rats/pigs) & habitat loss. All remaining birds were placed into captivity.
Very shy/secretive in wild.
Only found in captive facilities in N America & Guam.
Have loud raspy call.
They’re cavity nesters.
Pairs usually lay 1-3 eggs (most often 2) but often only 1 chick survives, often due to siblicide.
To capture prey, they swoop down & beat it side to side on branch to stun/kill before swallowing whole.
Sexually mature at 1.5 years.

Fun Fact(s):
Known as Sihek in Chamorro language spoken on Guam.
Less than 150 of these birds left in the world.
Though small, they’re highly territorial & often attack other bird species as well as conspecific. This means they don’t mix well w/ most bird species in captivity.
