The last remaining kakapos, heavyset flightless parrots that only live in remote parts of New Zealand, got busy this year.
A total of 37 kakapo chicks have survived so far in 2016, signaling the most successful breeding season since conservation efforts began for the critically endangered species more than 20 years ago.
That baby boom is a much-needed boost for the 123 adult birds remaining.
"The future of New Zealand's own giant flightless parrot is looking much brighter," New Zealand Conservation Minister Maggie Barry said in a statement.
Centuries ago, kakapos were plentiful across New Zealand, but the introduction of predators such as ferrets and weasels led to their decline. By the 1900s, the green-feathered birds were thought be to extinct, but in 1970 about 40 kakapos were found on Stewart Island, just off the southern tip of New Zealand's South Island.
Beginning in 1995, kakapos were transported to three predator-free islands, where the birds are monitored. The last egg hatched April 8, and all the hatchlings will be checked and weighed regularly until they fledge from the nests at about 10 weeks old.
They won't be added to the official kakapo count until six months after their birth, said Barry.
This year marked the first time successful hatches took place on all three islands, as kakapos are notoriously picky breeders, according to the New Zealand Department of Conservation. They only reproduce every two to four years, depending on the availability of fruit from trees—their primary food source.
Deidre Vercoe, the conservation department's kakapo operations manager, told The Guardian that improvements in remote-sensing data and monitoring equipment that allows for a more "hands-off" approach to kakapo management could be part of the reason for the successful breeding season.
"This is a turning point for us," she said. "These kinds of technological advances are enabling us to look after more kakapo in a non-invasive way, and as the population grows, these tools will be crucial."

Three black footed ferrets huddle in a temporary housing unit as animal keepers at the National Zoo's conservation center in Front Royal, Va., on Wednesday, Sept. 28, 2011. This shipment marked an important moment in the recovery of a species once declared extinct. Researchers rediscovered the black-footed ferret in 1981 and collected the last 24 in Wyoming to try to save them. Now 1,000 are again living in the wild. (AP Photo/Cliff Owen)

Investigators have begun a search in hopes of finding what may be the last free-roaming axolotl. Not one axolotl was found during last year's effort at finding them in the wild in Xochimilco, their only natural habitat. The axolotl is known as the "water monster" and the "Mexican walking fish."

A conservation group says the federal government hasn't done enough to save the endangered dusky gopher frog because it has yet to write up a rescue plan. The Center for Biological Diversity's legal notice of plans to sue comes about three months after a property rights group filed such a notice claiming the Interior Department has gone too far in protecting the frogs, which spawn in ponds so shallow they dry up in the summer.

A giant soft-shell turtle which is considered a sacred symbol of Vietnamese independence is guided into a cage for a health check by handlers at Hoan Kiem lake in the heart of Hanoi. Thousands of onlookers cheered in central Hanoi on April 3, 2011 when rescuers captured for treatment the ailing and ancient giant turtle. Legend has it that the turtle is the guardian of a magical sword once used in the 15th century to drive out Chinese invaders. Concern has mounted in recent months over the health of the animal likely to be over 100 years old and one of the last of a critically endangered species -- it is one of only four Rafetus swinhoei turtles known to exist in the world.
