In these early days of 2019, I thought it might be a good time to look back at some of the top bird-related stories of 2018. Here are my Top Five picks:
Mother of Mothers
Wisdom the albatross nested again at age 67. Wisdom, according to the Fish and Wildlife Service website, is the oldest known banded bird in the wild. She is a female Laysan albatross that nests within the world’s largest albatross colony on Midway Atoll National Wildlife Refuge. She is at least 67 years old and a world-renowned symbol of hope for all species that depend upon the health of the ocean to survive.
Famed ornithology expert Chandler Robbins banded Wisdom on Dec. 10, 1956. Forty-six years later, he banded her again.
Albatrosses and other seabirds return to the same nesting site each year. Wisdom has been using the same nesting site on Midway Atoll since she was first banded. Albatrosses lay a single egg and incubate it for a little over two months. After a chick hatches, it will still be another five months before it will leave the nest. In that time, Wisdom and her mate, Akeakamai, like all albatross parents, take turns incubating the egg or caring for the chick while the other forages for food at sea.
“Midway Atoll’s habitat doesn’t just contain millions of birds, it contains countless generations and families of albatrosses,” said Kelly Goodale, U.S. Fish and Wildlife Service Refuge Biologist, in a press release. “If you can imagine when Wisdom returns home, she is likely surrounded by what were once her chicks and potentially their chicks. What a family reunion!”
Wisdom’s also a real survivor. For instance, she survived, along with her chick, the earthquake and tsunami that killed many Laysan and black-footed albatrosses on Midway Atoll in 2011.
New birds continue to be discovered around the world. For example, a research team has described an unusual new songbird species. The bird was named the Rote leaf-warbler (Phylloscopus rotiensis) after the island where it is found.
This new species of leaf-warbler, which has an unusually long bill, was first discovered on Rote Island, Indonesia.
Each year, about five to 10 new bird species are described worldwide. The fact that this bird is the second novel species described from Rota last year is also noteworthy. The other species — the Rote myzomela (Myzomela irianawidodoae) is a species of Indonesian honeyeater endemic to the island of Rote. Although first noticed years ago, scientists only confirmed this past year the the bird is actually a distinct species.
On this one small island in the Commonwealth of the Northern Mariana islands live two other birds found nowhere else in the world: the Mariana crow and the Rota white-eye. These birds are testimony to both the resilience and fragility of the world’s birds.
In an example of the fluidity of some species of birds, experts have confirmed a rare three-species hybrid with DNA from three different New World warbler species. As the warblers are my favorite family of birds, I found this a fascinating story.
The bird found in Pennsylvania was the offspring of a hybrid warbler mother and a warbler father from an entirely different genus. This is a combination never recorded before now, which resulted in a three-species hybrid bird. The bird is the offspring of a female hybrid between a blue-winged warbler and a golden-winged warbler. Its father was a chestnut-sided warbler, which is not considered a close relative of the other two warblers
Condors Soar Again
California condors continue to climb back from the brink of extinction. For the first time in more than three decades, an endangered California condor chick successfully fledged from a cliff-side nest in Santa Barbara County in California in November of 2018. Condor number 933 took its first short flight after being raised by its parents for six months in the northern Santa Barbara backcountry of Los Padres National Forest. This chick represents another milestone in the condor recovery program: the first second-generation wild fledgling in Southern California. Its father fledged from the Santa Barbara backcountry in 1980.
The chick known as Condor 933 hatched in late April and was raised by six-year-old female condor 654 and 38-year-old male condor 20, more popularly known as AC-4.
Official USFWS statistics from December 2016 recorded an overall population of 446 condors, of which 276 are wild and 170 are captive. A key milestone was reached in 2015, when more condors were born in the wild than died.
The goal of the California Condor Recovery Plan is to establish two geographically distinct self-sustaining populations, each with 150 birds in the wild and at least 15 breeding pairs, with a third population of condors retained in captivity. As the Recovery Program works toward this goal, the number of release sites has grown. There are three active release sites in California, one in Arizona and one in Baja, Mexico.
Despite the success stories, birds are getting hit hard in the age of extinction sweeping our planet. Some of this year’s extinction casualties included a diminutive Hawaiian species known as the , as well as the Brazilian birds known as the cryptic treehunter and the Alagoas foliage-gleaner. Spix’s macaw — a parrot species made famous by Disney’s animated feature film Rio — is now extinct in the wild, although about 50 individuals survive in captivity. The announcement about the macaw was a formality. Scientists have suspected the species is extinct in the wild since 2011 when the last known female Spix’s macaw perished. The announcement in September of 2018 served as a mere formality. Unfortunately, things will probably only get worse for many bird species in the short-term future. We must never begrudge the resources needed to keep them all flying free.
