Monday, September 1st will mark the 100 year anniversary of the death of Martha, the last of her species, the Passenger Pigeon. With her death our planet lost another species forever to extinction. This week we'd like to share some of the commemorative events and educational opportunities that are taking place to mark this important centenary.

We know the exact moment that the Passenger Pigeon went extinct, because the last of the species was a known captive individual named Martha. The last known individual of a species (or sub-species) is sometimes known as an endling.

Martha is not the only endling known to the world. Here are some other notable individuals that were the last of their kind.

The Tasmanian Tiger was extinct in the wild by 1930. The last captive individual died at the Hobart Zoo on September 7, 1936. Since 1996, Australia has annually commemorated the date as National Threatened Species Day.

Very recently, a Pinta Island Tortoise named Lonesome George passed away on the Galapagos Islands. He was the last of his kind, a subspecies of Galápagos Tortoise. He was thought to be at least 100 years old when he passed away on June 24, 2012.

The Quagga was a subspecies of the Plains Zebra that lived in South Africa. Dutch settlement of South Africa doomed the Quagga as it was in competition for food with domestic animals. The last wild Quagga died in South Africa by 1878. The last individual Quagga on earth died at the Artis Zoo in Amsterdam on August 12, 1883.

The Carolina Parakeet is another species of bird that went extinct in North America in the early 1900s. The last known wild bird was killed in 1904, while the last captive individual, a male named Incas, died at the Cincinnati Zoo on February 21, 1918.

Passenger Pigeons once ranged across a wide part of eastern North America. Their preferred breeding habitat was deciduous forest; winter roosting sites were either in swamps or pine forests. Here are some more interesting facts about this species.

1) When Europeans first arrived in North America, there were an estimated 3 to 6 billion Passenger Pigeons on the continent. They were certainly the most abundant bird species in North America, and possibly the entire world.

2) Passenger Pigeons could fly 50 to 60 or more miles per hour. They had very strong breast muscles and long wings for strong flying.

3) Passing flocks of Passenger Pigeons would darken the sky and take days to pass an area.

4) Passenger Pigeons were larger than the familiar Mourning Dove. From head to tail they measured 15 to 16.5 inches long and weighed 12-14 ounces.

5) Adult Passenger Pigeons pairs would raise just one chick per year. Both parents would incubate the egg and care for the growing chick.

6) Passenger Pigeon chicks were called squabs (as are other pigeon and dove babies). Fat Passenger Pigeon squabs would fall from the nest before their first flight. The baby would remain on the ground until it was able to fly, usually a few days later.

7) Passenger Pigeons nested in huge colonies, some covering up to 850 square miles or more. A single tree may have held up to 500 nests at one time.

8) Passenger Pigeons dined primarily on nuts: acorns, chestnuts, hickory nuts, and beech nuts.

9) The term "stool pigeon" originates from the culture of hunting Passenger Pigeons. A single captured pigeon would be tied to a stool and then dropped onto the ground. Pigeons flying above the unfortunate captive would take this as a sign to land in the same spot. In this way, entire flocks could be easily captured or shot.

10) After decades of decline due to both over-hunting and rapid deforestation, the last Passenger Pigeon, an individual named Martha, died at the Cincinnati Zoo on September 1, 1914. Her exact age was unknown, but she may have been as old as 29.

There's no shortage of books written about Passenger Pigeons. Their journey from incredible abundance to shocking extinction is well-known. Here are just a few titles relating to Martha and her species.

This book about the Passenger Pigeon, the first new major work about the species in over 50 years, was published earlier in 2014. A Feathered River Across the Sky: The Passenger Pigeon's Flight to Extinction by Joel Greenberg tells the epic story behind the extinction of the Passenger Pigeon while drawing ties to our current relationship with the natural world.

The Passenger Pigeon by W. B. Mershon was first published in 1907. Unlike modern works, here the author gives a first-hand account of interacting with the species, its decimation at the hand of man, and its apparent impending loss.

The Passenger Pigeon by Errol Fuller is another title being released in this anniversary year. Fuller has experience writing about extinct species; he has authored books about the Dodo, the Great Auk, and other Lost Animals.

The Silent Sky: The Incredible Extinction of the Passenger Pigeon, first published in 1965, tells the extinction story in readable novel form. The book follows the life and death of the last known wild Passenger Pigeon.

Fold the Flock is a project to help us remember the amazing Passenger Pigeon flocks of the past. The project involves participants folding origami pigeons; their goal is to accumulate a virtual flock of one million folded pigeons by the end of the year. The flock is now just over 300,000 400,000 birds strong.

Participants can download a free PDF origami sheet to fold, or purchase origami kits containing 50 sheets. Folding a origami Passenger Pigeon is fun and easy! The PDF download has clear instructions; this animation of the folding process clearly shows all the steps.

Once you've got the hang of it, using recycled paper can make your flock colorful and unique as well as environmentally friendly. Once you've folded one or more pigeons, add your bird(s) to the flock - an online registry of all of the origami Passenger Pigeons folded by participants around the world.

Among other goals, Project Passenger Pigeon (PPP) was created with the aim to "familiarize as many people as possible with the history of the passenger pigeon and its extinction; raise awareness of how the issue of extinction is ecologically, culturally, and morally relevant to the 21st Century; encourage and support respectful relationships with other species; motivate people to take actions to prevent human-caused extinction, and to promote biodiversity through habitat preservation and restoration, captive breeding programs, government initiatives, and other measures."

There are a lot of educational resources and activity ideas available on the site. In order to reach as many people as possible, PPP has listed several different ideas for getting everyone involved. These include lesson plans for elementary and high school students; a shareable Powerpoint presentation; theatrical plays; a symphonic composition; and more. If you are looking for an easy activity for younger children, consider downloading our free Birdorable Passenger Pigeon coloring page.

A new documentary about Passenger Pigeons was created to coincide with this anniversary. From Billions to None: The Passenger Pigeon's Flight to Extinction follows the amazing demise of what was probably the most abundant bird species on earth. It also notes the threats facing species today and what we can do to avoid the human-driven loss of more species. Here is a long trailer for the documentary created for its fund-raising campaign.

From Billions To None is now complete and recently had its world premiere screening in Chicago. Soon the documentary will air on PBS channels across the United States. The program is scheduled to air tonight on WNPT in Nashville, and later this month on public broadcasting stations in Indianapolis, Kentucky, and Chicago. A partial list of airings can be found here; follow the From Billions to None on Facebook to learn of more airings and/or check your local listings.

Birds don't wear diapers. But in some songbirds, babies expel their waste in a membrane-filled sac, which is then removed from the nest by a parent.

Keeping the nest clean isn't just about good hygiene. Removal of waste reduces the chances that predators will find (by scent) the vulnerable nestlings. It may also help to prevent illnesses developing in the baby birds. Fecal sacs are removed from the nest, sometimes right as they are being produced! Some baby birds give a 'signal' to indicate they are about to eliminate (poop). The below video shows a baby American Robin shifting around in its nest to expose its backside. The adult waits for the sac and then removes it immediately.

Some baby birds leave their fecal sacs along the outer edge of the nest for later removal, as can be seen in this video of a Carolina Wren nest, though the adult happens to remove the sac immediately in the clip. Sometimes the need to eliminate comes immediately after feeding, which can be seen in clearly in this video. Most people aren't even aware that this amazing baby bird "diaper service" exists. But if you live among Common Grackles, and you happen to have a swimming pool, you just might be painfully aware of fecal sacs. Grackles are naturally inclined to deposit fecal sacs in water - streams, ponds or rivers, traditionally. However, if a swimming pool is convenient, it might just end up being a favorite "sewer service" for neighborhood grackles!

Earlier this month, scientists named the 100 most unusual and endangered birds in the world. The species on the list were taken from the world's approximately 10,000 bird species, and ranked by their evolutionarily distinctiveness and conservation status. Here at Birdorable we like to highlight both unusual birds as well as species that need conservation help.

Eleven of the birds on the top 100 list can be found here in our unique cute cartoon style. Birds on the list include the iconic California Condor, struggling back from the brink of extinction thanks to dedicated scientists and conservationists, and the unusual Shoebill, which is also known as Whalehead or Shoe-billed Stork.

The list of endangered and unusual birds also includes species in the parrot family, like the nocturnal and non-flighted Kakapo, endemic to New Zealand, and the Spix's Macaw of Brazil. Other Birdorable birds on the list: Philippine Eagle; Spoon-billed Sandpiper; Northern Bald Ibis; Red-headed Vulture; Secretary Bird; Egyptian Vulture; Kokako.

These birds and all of the others on the list are in conservation trouble, just like the Passenger Pigeon was over 100 years ago. This year marks the 100th anniversary of the final loss of this species. In September 1914, the last Passenger Pigeon died, and the species was lost forever. If you can, please support groups working hard to save species by conserving habitat, enacting regulations that help the environment, and other heroic deeds to help our fellow creatures of Earth. Share your love of birds and the environment so that others may share your passion and work to save those in trouble, too!
