Sind Sparrow

Passer pyrrhonotus

Sind Sparrows look very much like the House Sparrows that live throughout Europe and Asia, though they are a tad smaller, and are located only around India and Pakistan. It is easiest to tell the two species apart when looking at the males. Sind Sparrows have short black bibs on their throats. House Sparrows have the same bibs, but they are much larger. Females are much harder to tell apart, tricky birds! They do have different calls though, with the Sind Sparrows having higher, more staccato-like voices.

So why so much similarity? Well, the two birds are definitely relatives-- the share the same genus (along with about two dozen other species). The original thought was that the Sind was a newer species that evolved from populations of House Sparrows cut off during the last Ice Age (around 15,000 years ago). But now, new genetic studies are showing that the Sind Sparrows may have split apart millions of years ago, rather than thousands.

Sind Sparrows live in small little groups that number around half a dozen birds, though these groups can swell to larger numbers during the winter (the non-breeding season). These groups forage for grass seeds in areas near rivers.

When it comes time to reproduce, both sexes help to build the nest, which is an untidy collection of sticks placed a few meters up into the trees. Both parents also help with the incubating.

Oriental Dwarf Kingfisher

Ceyx erithaca

Today's animal is an absolutely stunning little bird, sporting bright yellow, red, and bluish-black plumage. Though we'll refer to them as the Oriental Dwarf Kingfishers, they are also sometimes called Black-backed Kingfishers, due to the darker colors that contrast with the bright feathers elsewhere.

If you're looking for a Oriental Dwarf Kingfisher, you'll find them (well... maybe... they are very elusive) in south and southeast Asia, where they live in dense forests near small bodies of water. Water plays an important role in their lives-- they breed during the very wet monsoon season and they feed on aquatic animals. And while were are speaking of breeding, these Kingfishers build tunnel-like nests that can measure over 3ft in length!

At present, the Oriental Dwarf Kingfisher is listed as being of Least Concern, but the population is on the decline. Habitat loss is the number one threat to their numbers.

Mountain Pygmy Possum

Burramys parvus

The Mountain Pygmy Possum is a tiny little Marsupial whose prehensile tail is actually longer than the rest of its body! They are only about the size of a mouse, measuring only a few inches in length, and weighing just 45g. They have dense dark fur on the top, with lighter undersides.

Mountain Pygmy Possums are rare and critically endangered. They were actually considered extinct until 1966, when the first live one was found (before then they only known from fossil forms).

Only three populations of these little guys are known to science, and it is believed that there are less than 2,000 individuals left. All three of these populations are found in southern Australia, in either New South Wales or Victoria. The Possums live in rock screes and boulder fields of high elevation areas. They are the only Alpine Marsupials in Australia.

Mountain Pygmy Possums also have the distinction of being more terrestrial than their other Possum cousins. While they are still excellent climbers, they spend most of their time on the ground. They are a nocturnal species, and hunt moths during the evening hours. During the winter months they hibernate, surviving off of stored up fat reserves.

Yellow-spotted Millipede

Harpaphe haydeniana

Not all Millipedes are gigantic like the big, 15in long African Millipedes. Today's animal is one of those Myriapods on the smaller side of the scale-- it doesn't get much bigger than 2in long!

The Yellow-spotted Millipede is found along the Pacific coast of North America. They are very important members of their ecosystem, as they help to break up leave litter and release nutrients.

As adults, have these Millipedes have predominantly black bodies with yellow patches that run along the sides. When full grown they have 20 body segments. Females have 31 pairs of legs, while males only have 30. The difference in number has to do with the placement of the males' reproductive organs.

Did you know that Yellow-spotted Millipedes have very few predators? Though they live in an area with lots of invertebrate-eating creatures, they remain very safe. This is because they have the ability to secrete Hydrogen Cyanide! The species is sometimes called the Almond-scented Millipede, due to Cyanide's almond-like smell.

Brown-throated Sloth

Bradypus variegatus

There are four species of Three-toed Sloth in the world, and the Brown-throated Sloth is the most common of the bunch. They can be found in different forested areas of Central and South America, typically living at elevations below 4,000ft.

Brown-throated Sloths can walk on the ground (kind of...), and they can even swim, but they spend almost all of their time up in the trees. They sleep as much as 18 hours a day, though 14-16 is more common. They are active the rest of the time, feeding and moving and protecting their territory, but only in 2-3 hour bursts.

The home range for a Brown-throated Sloth is pretty small-- only around a dozen acres. In this range they will move from tree to tree, feeding slowly on different leaves and fruits. Their metabolism is so slow that it can take a month to digest a single meal! In fact, the Sloths will usually only descend from their arboreal homes in order to go to the bathroom. This happens only once every eight days!

Brown-throated Sloth

Brown-throated Sloths have some interesting anatomical features, including their hair-- each follicle has multiple cracks on the surface. These cracks are the prefect places for algae to grow. The algae get a nice host to live on, and the Sloths get some extra camouflage. But the algae aren't the only passengers that the sloth has. A species of moth, Cryptoses choloepi lives in the Sloth fur and lays its eggs in the Sloth's dung.

Other strange anatomy facts? Brown-throated Sloths have 10 cervical vertebrae, and can rotate their necks 270 degrees. They also have a lot of trouble regulating their body temperature due in part to their small hearts and lack of muscle mass. This is why Sloths are only found in tropical warm areas.

Females sloths will make loud vocalizations in order to attract a mate. A male will come to her, and she will usually mate with the first one to show up. After copulation the male leaves, and the female goes through the 5-8 month gestation period alone. They give birth either on the ground or in trees, and the young sloth will cling to its mother's underside for up to 5 months. They wean quickly but stick around for much longer to learn important Sloth skills from mom, including motor skills and which leaves are best to eat.

Green Ibis

Mesembrinibis cayennensis

The Green Ibis is a short little wading bird that also happens to be the only member of its genus. It can be found in Central and South America, living in wetlands and swampy woodland areas. These birds are typically residents of an area, though some may make very small migrations during the dry season.

Though it may not look it, depending on the light, the Green Ibis is actually green. It's a dark green, and sometimes it appears black, but it's green nonetheless. Juveniles have the same coloration, only it is more dull. They look quite a bit like the Glossy Ibis, but are more broad and have shorter legs.

You will find the Green Ibis living either alone, or in very small groups. Pairs are monogamous, and will build large platform nests in the trees, laying between 2 and 4 eggs each brood. They feed on water creatures like fish and frogs, and will take insects as well.

The species has a decreasing population, but it is still very large and they have an extensive range. They are currently listed as being of Least Concern, but that may change in future years.

Green Stink Bug

Acrosternum hilare

Today's animal is quite the stinker! Literally! The Green Stink Bug has a very large gland on the underside of its thorax. These glands discharge a huge (for a bug) amount of smelly liquid when the bug is disturbed.

You can find Green Stink Bugs across North America, and they are the most common Stink Bugs on that continent. They are actually considered to be pests in some places, due to their love of seeds, grains, and fruits. They are not at all picky when it comes to food, and can have many, many different types of host plant that they snack on with their needle-like mouths.

Green Stink Bugs are shield-shaped and vibrantly green in color, even as small nymphs. Nymphs come from tiny barrel-shaped eggs that are laid on the undersides of leaves. One new generation is laid each year in the northern range, while two are more common in the south.
