Alala Hatching Update"”Heading for the Record
Posted at 11:14 am June 2, 2004 by Alan Lieberman
The 2004 breeding season for `alala is beginning to shape up as one for the record books. The best breeding season until now was seven years ago (1997) when there were nine chicks hatched and reared. Thus far this season, the Hawaii Endangered Bird Conservation Program has hatched and is now rearing nine chicks, and the season isn't over yet. No one likes to count their chicks before they hatch, so we must show restraint and merely say, " All is looking good for a double-digit chick season, the first ever!"
In the program, there are a total of 40 adult `alala plus this season's first 9 chicks. This makes a grand total of 49 'alala for the entire world, since the species is likely extinct in the wild. These 9 chicks represent a nearly 25 percent increase in the world population. There are 13 pairs of birds set up for breeding; of these, 11 females have laid eggs, with 8 females producing fertile eggs, showing that both the females AND males are doing their respective jobs. Three of the pairs are housed in the Maui facility and ten of the pairs are at the Keauhou facility on the Big Island.
The chicks are initially fed a diet of bee larvae, cricket innards, and hard-boiled egg. As they grow, items like mouse parts, papaya, and mealworm soft parts are added to the mix. As soon as the chicks' eyes begin to open (at about two weeks of age) they are fed using an `alala puppet to help them recognize themselves as `alala (and not as the humans who are doing the feeding). At a little more than one month of age, the chicks will begin to spend time in an outside aviary so they can listen and watch the adult `alala and begin the process of learning how to become a member of their species.

To the delight of the staff at the Maui Bird Conservation Center, a Maui parrotbill chick hatched on May 17, 2004. This is the first chick of this species to hatch at the center from a captive-laid egg. This egg was removed from the nest two weeks before, to avoid damage by the parents. They had already broken the first egg laid this year and the program did not want to risk losing the second egg. The mother of the egg was hatched in captivity in 1999 from a wild-collected egg and the male was brought to the Center for rehabilitation after it was injured in the field in a mist-netting mishap in 2001. The pair has been socialized together for the past two years but this is the first year they actually began to lay eggs.
One of the most useful tools in the management of captive pairs of birds is video observation. Not only do video observations satisfy one's curiosity as to who is doing what to whom, carefully managed observations can reveal very interesting patterns of behavior. These careful and methodical observations allow the biologists at the Keauhou and Maui Bird Conservation centers to record critical events in the breeding cycle of difficult-to-manage species like the `alala.
A flock of ten palila was reintroduced to the area of Puu Mali on the north side of Mauna Kea Volcano. This important event adds another species to the growing list of Hawaiian species propagated and released into native habitat. These ten individuals included three birds that were hatched in 1996 from wild eggs that were brought into captivity and have produced over 20 offspring since then. 
In addition to the new `alala aviaries being built at the Keauhou Bird Conservation Center, there have been significant renovations made to one of the `alala aviary complexes at the Maui Bird Conservation Center.
As the captive population of `alala grows, it becomes necessary to increase the number of aviaries to accommodate the additional birds. The species is now considered to be extinct in the wild, so every effort must be made to maintain and, indeed, increase the number of birds in the managed captive flock in preparation for the future release of the birds into protected managed habitat.
The aviculturists at the Hawaii Endangered Bird Conservation Program celebrated a " first" on June 3, 2003. The focus of our excitement was something small in size but significant nevertheless. We had propagated the world's first captive-hatched Hawaii `akepa!
The puaiohi Myadestes palmeri is an endangered cocoa-brown songster from the dripping forests of the Alaka`i Wilderness Area on the Hawaiian island of Kauai. The recovery effort for this bird relies on the cooperation of various organizations: U.S. Fish and Wildlife Service (USFWS), U.S. Geological Survey's Biological Resources Division, the State of Hawaii's Division of Forestry and Wildlife, and the San Diego Zoo. In a meeting held in Honolulu, Hawaii on June 30, 2003, representatives from each of the agencies and organizations presented the results of the past year, reviewed the status of the program, and agreed on common goals to accomplish for the next year.
Very often we hear the comment, " So ugly, only a mother could love it." Well, here at the Keauhou Bird Conservation Center we must all be mothers, or at least surrogate mothers, because we really do have an emotional as well as professional bond with these `alala Corvus hawaiiensis chicks. This year's `alala breeding program has been slower than we anticipated, but productive nevertheless. The three chicks being reared at the Center are now out of their hatchers and are being reared together in a box brooder. These youngsters are reared together, as they would be in nature, to help them develop the behaviors appropriate for an `alala. At about nine or ten days of age they are covered in pinfeathers and down with their eye slits just beginning to open. As soon as they can see, we will begin to feed them with an `alala puppet so as not to imprint the chicks on their human " mothers."
