Creature Feature: Vasa Parrots.

Oh! A Creature Feature! It's been a while, hasn't it? Let's look at the weirdest parrot you've eeeeveer seen:



This long-legged, uncanny parrot is a Greater Vasa parrot (Coracopsis vasa). Vasa parrots of all species are native to Madagascar (AKA "that African island with lemurs that got a movie series." Yes, you can get them as pets, but please do your homework.

First of all, these parrots are black. Not gray like an African Gray, not iridescent - gray-black. It's not glossy black, like a crow, but more of a matte black - charcoal black, if you will. That's virtually the last color one expects from a parrot. The pinkish bill stands out, too, making for a striking bird on the whole.

Vasas are thought to be among the most primitive of parrots. Some of you who keep up with animal news might remember a deal a while back when it was found that not all "raptors" - that is, eagles, falcons, hawks, and owls - were related. In fact, parrots are quite closely related to falcons, and the vasa's got some pretty good evidence of this, starting with being a hunting parrot. Females are also larger and dominant, as they are in birds of prey. They also have another very primitive trait that I will get to later, but

Then these parrots start showing their mating colors. What, do I mean that the black suddenly erupts into multicolored plumage? Oh, I wish; vasa parrots have a much stranger mating patterns. Mating groups are open, to say the least, with any given female having 3-8 males in her non-exclusive manharem. The skin of the female turns yellow-orange beneath her feathers while she's tending young...and then she becomes bald so that everybody can see it:



Vasa are also the only parrots to have hemipenes. The cloaca, usually dickless, everts when the birds are mating. The lock can last for up to an hour. That's probably more than you ever wanted to know about parrot sex, but there you go. 

Creature Feature: Giraffe Weevil.

Insects are automatically nightmare fuel when it comes to creature design. With the possible exception of butterflies, there is no insect on the planet that cannot be made into an object of terror. Even harmless, annoying things can be magnified into monsters. Weevils, which are already terrifying if seen up close, reach the peak of their horror monster potential in this fellow:



This bug-meets-Apatosaurus creature is called a giraffe weevil (Trachelophorus giraffa) . It is native only to Madagascar, second only to Australia for the title of "World's Weirdest Island." They are herbivorous like all weevils, partial to seeds and fruit. New Zealand also has a "giraffe weevil," so just to be clear, this one is from the island with happy lemurs.

The giraffe weevil cannot help but stand out. That long neck on the males is 2-3 times the length of the females. It is almost an inch log - not the record for weevils, but still quite big for one. It has a striking, red and black palette. No, it is not poisonous as far as my sources know. Seeing a giraffe weevil in the wild must be amazing. The bright  color and long neck both make it unforgettable.



This long neck is for one very important purpose: Mating. Specifically, male giraffe weevils fight each other with their long necks. The females have much shorter necks, and referee the neck-fights between the two males. The winner gets laid. Fair enough.

This is not to say that the ladies of the species are not at all interesting. Unusually for insects, the female lays exactly one egg after mating. She then encases it in a tube cut from a leaf. The leaf is then cut such that two edges mesh together-  effectively, primitive Velcro. The leaf nest then drops to the forest floor, where the weevil will hatch, grow, and repeat the process.  Giraffe weevils: males look freaky, females invented Velcro before people.
