In most bird families, males and females both participate in the raising of their young. In 8% of cases, the female does everything related to care of eggs and raising offspring. And in just 1% of bird species does the male do all of the work -- after the eggs are laid, of course.

Some species are polyadrous, meaning individual birds will have different mates during the same breeding season. In the case of the Spotted Sandpiper, females will often have two clutches, the first of which she leaves after the eggs are laid. It's up to her mate to incubate the eggs and rear the chicks. She will then find a new mate and help to raise her second clutch with the new male.

Emus exhibit similar behavior, though male Emus go through a more extreme experience during incubation. During the approximate 8-week period, he does not leave the nest for any reason. He may lose up to a third of his bodyweight while he forgoes eating, drinking, and even defecating, standing up only to turn the eggs. Once the chicks are hatched, father Emu will protect his young for up to seven months, which is about how long it takes for them to fully grow. The group may stay together as a family for up to two years.

The paternal (father) duties of the Emperor Penguin are widely known. After the female lays the pair's one and only egg, she carefully transfers it to the male. And then she leaves him for two months. While she is out to sea, feeding, the male remains behind, incubating their egg between the brood patch on its underbelly and its feet. When the egg hatches, the male may have been fasting for over 100 days since he first arrived at the breeding colony. Once his mate returns, she cares for the chick so the male can finally go to the sea to find food.

Hornbills have an unusual breeding strategy that involves the female being practially sealed inside the nest cavity with the eggs, with only a small slit left open. This small opening allows the male to transfer food to his mate and to the chicks, once they hatch. During incubation and the hatchling phase, the family relies entirely on the male to provide food. The mother and chicks only leave the nest once they are too large to remain inside.

Happy Father's Day to all of the dads out there, avian and otherwise!

Traditionally, April Fools' Day is a time to play pranks, share hoaxes, and tell jokes. April Fool stories published by newspapers and other media outlets may trick readers into believing tall tales -- until they realize the date. Here are some bird-themed funnies that have come out on April Fools' Days in the past.

A lot of April Fool jokes involving crazy bird stories originated from photo manipulation -- an old-fahsioned version of "photoshopping". Examples of this include a German paper exposing a penguin as tall as a man in 1931; that time in 1941 when a newspaper revealed a military plan to plant bombs on crows; and the strange and silly rare human-legged ostrich that reportedly puzzled scientists in 1953 Australia.

Google is known to reveal a prank each April Fools' Day, often involving a new product or service in their technology offering. In 2002 they introduced PigeonRank to the world, exposing the truth behind their search technology. Pigeon Clusters (PCs) were the true power Google used to rank and sort web pages. The somewhat elaborate story behind PigeonRank was shared in detail, including graphs and diagrams and a FAQ.

A popular video was released by the BBC in April Fools' Day 2008 which showed Adelie Penguins taking flight. At the time it was one of the most viewed internet videos.

A mysterious physical April Fools' Day prank was played on the town of Portage, Wisconsin in 2012. Plastic lawn geese dressed in different outfits were placed around businesses, homes, and services in the city. In all, 132 geese were found. Although the perpetrators were not made known, no one who received a goose seemed to mind. Read this extremely wholesome newspaper report on the incident.

Then there was that time when we revealed a new species of crane that was discovered in South America. We even shared a colorful Birdorable image of the new species, which we dubbed the Painted Crane (Grus pictus). This April Fool prank came out just as we were celebrating Crane Week -- it was an incredible coincidence!

Watch out for more pranks and hoaxes as you go about your day and keep in mind the date! Happy April Fools' Day!

Today, March 14, is traditionally celebrated as Pi Day -- because when the date is written 3/14, it represents the first three significant numbers of Pi. Pie day may be celebrated by eating pie, but since we like birds, today seems like a good day to celebrate the family of birds that has pie right in the name: Magpies!

There are three groups of true magpies. The four species of magpie in the genus Pica are the Holarctic, or black-and-white, magpies. The nine species of Oriental magpie are generally blue-green and are in the Urocissa genus and the Cissa genus. The azure-winged magpie belongs in the genus Cyanopica. Here are some fun facts about this group of intelligent and curious birds.

• Magpies belong to the Corvid family, which makes them closely related to birds like jays, crows, and ravens.
• The cartoon characters Heckle and Jeckle are a pair of magpies.
• There are several collective nouns used to describe a group of magpies, including "a gulp of magpies" and "a mischief of magpies."
• Magpies aren't the only birds with "pie" in their name. Another group in the Corvid family is the treepies. One bird in this group has a confusing name: the Black Magpie of Asia.
• Another bird with a confusing name is the Australian Magpie. This species isn't a magpie at all! Although its black-and-white plumage is very magpie-like, this species belongs in a different genus and is closely related to the Butcherbirds of Australasia.
• A recent taxonomical split may have added a new species of magpie to the list. The Azure-winged Magpie has an usual fragmented range with part of the population in southwestern Europe and part over in eastern Asia. Some ornithologists consider the two populations to be separate species, naming the European bird the Iberian Magpie.
• The Javan Green Magpie is the most endangered species of magpie. Endemic to Indonesia, it is considered to be Critically Endangered by the IUCN. Other endemic species of magpie include the Sri Lanka Blue Magpie, found only in Sri Lanka, and the Yellow-billed Magpie, found only in the U.S. state of California.
