Last year was momentous at the Keauhou Bird Conservation Center in Hawaii. For the first time in over 20 years, alala (Hawaiian crows) successfully hatched and reared their own chicks in managed care, completely unassisted! Two chicks (a male and female) were raised by their mom, Po Mahina. To learn about her parent-rearing journey, read Alala: Does Mother Know Best? Another male chick was raised by a caring alala mom named Lolii. This gave us a total of three parent-reared chicks!
Before the species went extinct in the wild in 2002, young alala chicks were known to live with their parents until the following breeding season. Today I am happy to report that these three parent-reared chicks are doing fantastic. However, they just went through an experience that many animal species (humans included!) go through: the time to stretch your wings and move out of mom and dad’s house!
We wanted to move the chicks gradually and as stress-free as possible, so a few weeks ago we shifted them to the chamber next door to their parents. This way the chicks could still see, hear, and interact with their parents. Both the chicks and their parents hardly seemed bothered by this change! Then it was time for the big move. All of our alala are conditioned to come down to a hack box (a small room with sliding hatch doors) every day for their normal food pan. On the morning of the big move, the chicks were shut into their hack box, then quickly netted and placed into animal carriers. The chicks were then taken to their new home in a separate aviary, just a short car ride down the road. Once there, all three chicks were released into their new aviary at the same time.
Since Lolii’s chick was an only child, this was the first time for him to meet other chicks. We worried that he might have a harder time adjusting to living with other chicks, because getting used to new roommates takes some adjustment, whether you are bird or human! We also worried that Po Mahina’s chicks might gang up and bully Lolii’s chick, so we closely observed their interactions following the release. Our worry was needless, because everyone quickly worked out their differences, and at the end of the day, all three chicks were sitting together on the same perch!
What’s next for these three youngsters? For now, they will probably stay together for a couple of years until they become mature alala, around three years of age. During that time, their blue eyes will slowly start to transition to dark brown. Their bright pink gapes (corners of the mouth) will turn black like an adult’s. Instead of their boisterous begging vocalizations, they will soon sound like adults and call out to each other with an amazing repertoire of calls and songs.
What about those super moms? Po Mahina and Lolii’s breeding and nesting instincts are starting to kick back into gear. Now it’s time to turn on our alala video cameras so we can watch the parent-rearing process start all over again!
