A Little of Everything.
do you happen to know why bearded vulture's sclera (scelrae?) are red?

….That’s an excellent question, Anon.

To be honest, I always though that the red ring was just a marking around the eye, sort of like what you’d see on a raven, but closer inspection reveals that it is indeed part of the eye itself. So naturally, I had to do some googling, and here’s what I came up with!

It’s a thing called the scleral ring. It’s red because it’s actually full of blood, and it functions in the vultures’ threat displays. When a bearded vulture is stressed or feels threatened, it will force more blood into the scleral ring, causing it to expand and turn more of the eye a red color. (Source.) I guess this is meant to intimidate their aggressor, which seems pretty effective to me. Frankly, I’d be intimidated if someone’s eyes suddenly started turning bright red when we were having a disagreement.

Compare these different scleral rings:

So there we have it. Yet another reason why bearded vultures are boss-ass bitches.

The Kakapo

is largest, heaviest parot in the world. He’s flightless and it made him very vulnerable to predators introduced by mens in its habitat. It’s also nocturnal and won’t mate for life unlike many other parrot species.  But things are getting better for that species and their number almost doubled in the last 10 years. When calling for a mate, males will stand on a hole dug in the ground and do a very special “booming” sound you can hear there. The Kakapo have been getting a lot of attention lately and that is good cause that species really, critically need help.

The Kea

is closely related to the kakapo, but it still have the ability to fly. They are also very destructive as many parrots are and it goes as far as killing sheep! They would bite on the skin of the sheep’s back and make then bleed to death or get infections. They do awesome little noises though!

The kaka

look a lot more like the parrot we’re used to see, but it’s still related to kakapos and keas. He can fly, but he also have some nocturnal habits. Like the kakapo, this bird’s populations have been badly hurt by predators introduced by man, but it is slowly getting better. It seems they have 2 different “dialect”; One for the south and one for the north.

Belted Kingfisher (Megaceryle alcyon)
In Greek mythology Alcyone found her husband drowned and cast herself into the sea. The gods rewarded her devotion by turning her into a kingfisher and forbade the winds to blow during the “Halcyon Days” when legend has it that the kingfisher lays its eggs. 

Hey guys, I saw these at comic con and thought they were really neat. I know a lot of people follow me for animal art so I thought I’d reblog in case you guys wanted to check it out!

he Bearded Vulture (Gypaetus barbatus), also known as the Lammergeier or Lammergeyer, is a bird of prey, and the only member of the genusGypaetus. Traditionally considered an Old World vulture, it actually forms a minor lineage of Accipitridae together with the Egyptian Vulture (Neophron percnopterus), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks, and differs from the former by its feathered neck. Although dissimilar, the Egyptian and Bearded Vulture each have a lozenge-shaped tail – unusual among birds of prey.

It eats mainly carrion and lives and breeds on crags in high mountains in southern Europe, the Caucasus,Africa, the Indian Subcontinent, andTibet, laying one or two eggs in mid-winter that hatch at the beginning of spring. Populations are resident. This bird is 94–125 cm (37–49 in) long with a wingspan of 2.31–2.83 m (7.6–9.3 ft). It weighs 4.5–7.8 kg (9.9–17.2 lb), with the nominate race averaging 6.21 kg (13.7 lb) and G. b. meridionalis of Africa averaging 5.7 kg (13 lb).In Eurasia, vultures found around the Himalayas tend to be slightly larger than those from other mountain ranges.Females are slightly larger than males.
