The Alala Project Joint News Release-Eleven Birds Thriving in Hawai’i Natural Area Reserve, Jan. 24, 2018

Posted on Jan 25, 2018 in Latest Department News


Continual Monitoring & Preps Underway for Additional Releases


(HILO, HAWAI‘I) – You usually hear them before you see them.  There’s no mistaking the loud and often times synchronized cacophony of caws from eleven ‘Alalā released into a Hawai‘i Island Natural Area Reserve (NAR) last fall. These birds, seven young males and four young females, represent what conservationists hope is the beginning of a recovered population of the endangered Hawaiian crow on the island.  ‘Alalā have been extinct in the wild since 2002. Since the birds took flight from a remote forest aviary in September and October 2017, they’ve been under the daily, watchful eyes of a monitoring team from the Hawai‘i Endangered Bird Conservation Program, a field program of the San Diego Zoo Global (SDZG).  In partnership with the Hawai‘i Dept. of Land & Natural Resources, the U.S. Fish and Wildlife Service and others, SDZG reared the ‘Alalā at its centers on the Big Island and on Maui.


The ‘Alalā are tracked daily by using signals from the lightweight radio transmitters each one wears or simply by seeing them with the naked eye or through binoculars.  Their movements, their flights, what they eat, where they roost, their behaviors; virtually everything about these birds is closely monitored and carefully recorded. Of high interest to all the folks involved in The ‘Alalā Project is how the birds individually and collectively react to threats from predators. An initial release of ‘Alalā in 2016 was temporarily halted and surviving birds were brought back into the aviary after two were attacked by another native bird, their natural predator, the ‘Io or Hawaiian hawk.  Prior to their release, the birds now living in the Pu‘u Maka‘ala NAR received extensive anti-predator training.


“Similar to any predator-prey interaction there’s a lot that goes on that we don’t necessarily see, but the observations we’ve made indicate that the birds do identify ‘io as a predator and can take evasive action when needed,” explained Alison Greggor a post-doctoral research associate with SDZG. Last week the project team saw this in action.  Two members heard an eruption of ‘Alalā alarm calls and heard quick wing flapping. “A dark morph ‘io darted across an opening. Immediately after, a light morph ‘io crossed the opening with four ‘Alalā following it or chasing it above the canopy. All four ‘Alalā disappeared for about 15 seconds before the ‘Alalā came back to the release /feeder area.”  Dr. Greggor added, “At this stage we can’t be certain that the training is the crucial piece of the puzzle, but we like to hope that it helped.  Actually, being in the wild around predators, observing other forest birds and interactions with predators, is the best training they can possibly get.”


Another sign of how well they’ve accepted their new home in the forest is they are being observed foraging more often for native fruits, instead of relying on feeders placed strategically outside the release aviary. Joshua Pang-Ching, Research Coordinator for the Hawai‘i Endangered Bird Conservation Program noted, “In the beginning they would spend much more time at or around the feeders.  Now we see birds coming to feeders much less. We have seen an anecdotal shift in their use of the feeders and see birds daily foraging on the fruits and foliage of native trees.”  The supplemental feeders will remain in place for at least a year to ensure the newly “wild” birds have that extra helping hand they might need.


Greggor, Pang-Ching, and Jackie Gaudioso-Levita project coordinator, of The ‘Alalā Project, are all hopeful given how this released group of ‘Alalā is doing. Gaudioso-Levita said, “These birds have adjusted very well to their forest home and it’s just been really inspiring for all of us on the project to see and hear ‘Alalā in the wild again.”


It’s a sweet sound for the many people who’ve worked decades to get to this point. In time it’s hoped the distinctive caw of the ‘Alalā will again be heard loud and clear across broad landscapes of Hawai‘i island. Plans are underway to release additional birds in the NAR later this year.
