Bald Eagle

Haliaeetus leucocephalus
Well, it's the Fourth of July, so why not talk about the national bird of the United States? The Bald Eagle is a large fish eagle that can be found throughout North America. They typically live near lakes, rivers, and oceans, as fish makes up a large part of their diet. Some Bald Eagles will migrate, especially if their chosen body of water freezes over in the winter months.

Bald Eagles are powerful predators, and can catch and carry prey that weighs as much as, and sometimes more than, they do. They are also prolific scavengers and thieves, and will steal prey away from other birds. They are one of the largest raptor species on the continent, and females are slightly larger than the males.

It is believed that Bald Eagles form lifetime pair bonds, though repeated unsuccessful breeding attempts can cause a pair to split up. Bald Eagles built the largest nests in North America. They are frequently over 6.5ft (2m) wide, and can weigh hundreds of pounds. The pair will use this nest year after year, adding on to it over time.

Juvenile in Flight
Two eggs are typically laid at a time, and are incubated primarily by the female while the male continues to hunt. Chicks grow quickly and fly within three months. Juvenile Bald Eagles are fully brown in color, and will not obtain their characteristic white head until they are 4-5 years old.

Bald Eagles were once an incredibly threatened species. Pesticides like DDT caused serious harm to the birds, including infertility and thin egg shells. Protection for the species and the banning of DDT in 1972 has allowed Bald Eagles to rebound successfully. They are no longer listed by the United States Endangered Species list, and are ranked at Least Concern by the IUCN.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a

Four!

For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
