Costa's Hummingbird

Calypte costae (male)
The Costa's Hummingbird makes its home in the southwestern United States and in northern Mexico. They live in arid scrub areas, and feed on plant nectar and small insects. The body size of this species is quite small, measuring only about 3in.

Male Costa's Hummingbirds are brilliantly colored little guys, sporting green backs, black wings, and a vibrant purple head and throat. (Females are less colorful, with green backs and paler underparts). They use their flashy colors in order to attract females. Males perform elaborate zig-zagging passes and dives for viewing females, using the light from the sun to reflect off of the violet head feathers.

After mating, the pair separates, and the female will construct a small cup-shaped nest up in a tree. She lays two eggs which take 15-18 days to hatch. The young Hummingbirds are fully fledged after 23 days.

One especially amazing thing that I learned about these birds is that while awake, their heart can beat between 500 and 900 times per minute. And that isn't even while they are being especially active! They also have the ability to enter a torpor state (during cold nights). During that time the resting rate slows to a mere 50 times per minute-- what a huge difference!

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

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

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!
