Ranges stay general on purpose. Witness never publishes a location that could help someone find an animal already under pressure.

What threatens it

  • Mosquito-borne malaria
  • ʻIo predation on releases
  • Cats, rats & mongoose
  • Toxoplasmosis

Life cycle

Pairs mate for life. One to five greenish-blue eggs come between March and July, incubated by the female for three weeks; usually two chicks survive. Since 1996, breeding centers on two islands have carried the species.

Field notes

Every passage carries the number of the source it came from. Nothing here is written from memory.

The ʻalalā is Hawaiʻi's largest surviving forest bird: a soft-black crow with brownish wings and stiff throat feathers it raises in display.Source 1

It speaks in at least 34 distinct calls — shrieks, howls, whoops, and cries that sound almost human.Source 1Source 2

It was the forest's gardener, carrying and planting the seeds of native trees.Source 3Source 1

In 2002 the last wild birds were gone, and the species was declared extinct in the wild.Source 1Source 4

It survived indoors: from fewer than twenty birds in the late 1990s, conservation breeding has grown the flock past one hundred and ten.Source 4

Wildness is harder to restore than numbers. Releases on Hawaiʻi Island struggled, in part because the ʻio — the Hawaiian hawk — was waiting.Source 1Source 5

So in late 2024 the project tried a new island: five juveniles flew free in East Maui, where no ʻio live.Source 5

They wear GPS backpacks and visit feeder boxes while they learn to be wild.Source 5

In Hawaiian culture the ʻalalā are ʻaumākua — spirit guardians. Like our ancestors, a recovery specialist says: the forest wouldn't be there without these birds.Source 5Source 6

To witness the ʻalalā is to hold a door open — e hoʻolāʻau hou ka ʻalalā: may it thrive in its forest once again.Source 3

Did you know

A 2016 study showed the ʻalalā naturally makes and uses stick tools — among crows, a talent shared only with the New Caledonian crow.
