The alala, or Hawaiian crow, is a culturally and environmentally important species. Highly regarded in Hawaiian culture, this bird serves as a seed disperser vital to regenerating native forests on Hawaii island.
Declared extinct in the wild in 2002, collaborative work has led to an assurance population robust enough for some birds to be released back into the wild. That is a feather in everyone’s cap!
A clutch may contain one to four speckled, blue-green eggs about the size of a golf ball. By removing the eggs and artificially incubating them, the female may “double clutch” and lay more eggs.
Candling alala eggs regularly allows researchers to monitor the development of the embryos.
HATCHING A PLAN
The pink, featherless hatchling breaks its way out of the shell inside a “hatcher.” It is kept warm and humid so the chick remains hydrated during the strenuous process, which can take up to 36 hours to complete.
Newly hatched chicks require patient, frequent feedings. Every two hours, they are fed a precise diet including fruit, honeybee larvae, and cricket guts.
Staff at the Keauhou and Maui bird conservation centers (KBCC and MBCC) collect native berries and fruit for the growing alala.
Once the chicks’ eyes open, they are fed with alala look-alike puppets to prevent them from imprinting on humans.
Keepers maintain meticulous records on incubation parameters for each egg, and document the weight, food intake, fecal output, and developmental milestones for each chick.
SPREAD YOUR WINGS
At about two months old, when the birds can feed themselves, they are moved to an outdoor acclimation pen. This helps to prepare them for release into the forest.
