Emu

~ joannerambling ~ 4 Comments

This week we are looking at the Emu they are the second-largest living birds in the world, native only to Australia, and known for their speed, endurance, and unique breeding habits.

They stand up to 1.75–2 meters tall and weigh 50–55 kg (110–121 lbs), with brownish feathers with a shaggy texture; long legs adapted for running. They have three forward-facing toes, which help them sprint and manoeuvre quickly.

Some may know and some may not know but emus can run as fast as 50 km/h which is 31 mph, and they can jump up to 2 meters which is 7 feet and to that they are damn strong swimmer and move through water damn fast when they want to.

These birds are omnivorous with their diet consisting of seeds, fruits, flowers, shoots, and insects like beetles and grasshoppers. They will travel long distances to find food and water, often forming loose groups called “mobs.”

They will mate for life in the wild, the female will lay 7–10 large dark green eggs, each about 13 cm long, but it the male who incubates the eggs for ~60 days and raises the chicks, while the female often moves on to mate again.

Now are you wondering what they sound like, well the female makes a deep, low-pitched sounds that can sound like drumming and often described as a hollow and resonant sound. These calls can carry for long distances and are used for communication, especially during breeding season. Males tend to sound like a soft grunt.

These calls are used to attract mates, signal territory, or keep contact with other emus.

Have you heard of the Emu War of 1932 this was a war us humans lost, the Australian army tried to cull emus damaging crops, but the birds proved too elusive. Despite firing 10,000 rounds of ammunition, fewer than 1,000 were killed, and the “war” was considered a failure.

Cockatoo

~ joannerambling ~ 3 Comments

Last week I wrote about birds in general, this week I am writing about the Cockatoo.

Cockatoos are intelligent, expressive parrot’s native to Australasia, known for their dramatic crests, powerful beaks, and deep emotional bonds with humans. They’re among the most affectionate and long-lived pet birds.

There are around 21 recognized species, including the Sulphur-crested, Galah, Palm, and Major Mitchell’s cockatoos

They are native to Australia, New Guinea, Indonesia, and the Solomon Islands.

Typically white, black, or pink with dramatic crests; less rainbow-coloured than other parrots

Their beak is strong, curved with a unique “three-way bite” for cracking nuts and gripping objects

They live in flocks and form lifelong pair bonds, they are loud and expressive, you wouldn’t want one if you lived I an apartment due to their volume.

They like to eat seeds, nuts, fruits, roots, and insects; use their beaks and strong tongues to forage.

They have a lifespan: 25–60 years, with some living over 70 years in captivity, in the wild they live in tree hollows and both parents care for their young.

They reproduce through internal fertilization, followed by egg-laying and a dedicated incubation period of about 28–30 days. The female lays 1–3 eggs per clutch, typically spaced a few days apart. Eggs are laid in a nest cavity or nesting box lined with wood shavings or soft material. The eggs are white and oval, and both parents may take turns incubating them.

Incubation lasts 28–30 days, during which the eggs must be kept at a stable temperature (~37.2°C) and humidity (55–60%).

Eggs are turned regularly to ensure even development and prevent the embryo from sticking to the shell. They are born blind and featherless, relying entirely on their parents. Their feathers start appearing in a few weeks and by 10 to 12 weeks they are ready to leave the nest.

They are highly social and attentive parents, often forming lifelong bonds. They teach their young vocalizations, foraging, and social behaviours essential for survival.

Birds

~ joannerambling ~ 3 Comments

Hello everyone, this week we are looking at birds, did you know there are over 11,000 species of birds throughout the world and 800 different species in Australia.

Now I expect everyone knows that all birds have feathers, beaks and wings but not all can fly. I will talk about those that don’t fly next week.

The country with the largest number of different species in Colombia with about 1,917.

This remarkable avian diversity is due to Colombia’s unique geography and climate.

The country with the fewest bird species is Vatican City, due to its extremely small size and limited natural habitat. However, if you’re considering larger countries with more ecological context, Iceland is often cited as having notably low avian diversity.

Do you know the diet of birds, most eat plants and seeds but there are some that eat meat, meat eaters are considered birds of prey. However, there are some that are not like the Butcher bird and the Magpie both are native to Australia.

Birds that have musical voices are called songbirds; they have specially developed vocal cords which are called the syrinx which they use to produced sounds resembling songs. They also have a special section in their brain which helps them learn their songs.

The birds that fly do so to find food and avoid predators; birds have a very light skeleton and strong muscles and wings. The shape and size of their wings determine the distance between and type of flight they can do.

Birds have feathers for flight, insulation, communication, camouflage, and protection—making feathers one of the most versatile and essential adaptations in the animal kingdom.

However, their feathers are not just for flight, they have bright, patterned feathers are used in courtship rituals to attract mates. Males often display more vibrant colours than females. Birds fluff, spread, or raise feathers to signal aggression, readiness to mate, or submission.

Many birds have feather colours and patterns that match their surroundings, helping them avoid predators or sneak up on prey.

Some species molt into different plumage depending on the season for better camouflage.

Feathers protect birds from UV radiation, wind, rain, and physical injuries.

Dense feather layers help shield sensitive skin from harsh environments.

Rodents

~ joannerambling ~ 4 Comments

Hello everyone, it is hot here and it is the type of day that I feel like doing stuff for an hour or so then I need to have a rest.

Anyway this week we are looking at rodents they are the largest order of mammals with hour many species there are. There are around 2,500 different species around the world.

Rodents are found everywhere except in Antarctica.

The character traits of rodents are incredibly diverse, as they are the largest order of mammals. However, they share several key physical and behavioural characteristics that define the group such as.

They have sharp incisor teeth which never stop growing and are kept short by gnawing.

They lack canine teeth and some premolars, leaving a distinct gap (diastema) between their incisors and their cheek teeth (molars/premolars).

While most are small (mice, hamsters), the order includes the largest living rodent, the capybara which weighs up to 70 kg.

They typically have robust bodies, short limbs, and a long tail although tails vary greatly—some are bushy like squirrels, others are nearly hairless like rats, and some are short or stubby.

They rely heavily on their long, sensitive whiskers to navigate and explore their environment, especially in the dark, as their vision is often less developed with many being colourblind or have poor eyesight.

Also they lack sweat glands and dissipate heat primarily through their tails and ears, making them susceptible to overheating.

They are one of the most successful mammalian groups, inhabiting nearly every environment on every continent except Antarctica. They are highly adaptable to new and human-disturbed environments.

The majority are herbivores, feeding on seeds, nuts, fruit, and plants, but many are omnivorous (like rats), and some are specialized predators (like grasshopper mice).

They are known for their high reproductive capacity, having large litters and short gestation periods, which helps compensate for high predation rates.

Apes

~ joannerambling ~ Leave a comment

Ok this week we are looking still at primates but the ones we generally think of as being much larger. Those being apes which belong to different families and have key differences in their physical characteristics, behaviour, and evolutionary lineage.

There are 20 species of apes the smallest is the Gibbon with the gorilla being the largest.

The physical differences are such an ape’s tail is one straightforward way to tell them apart, what is the main difference apes do not have tails, generally speaking,

Apes are generally larger and have a more robust build than monkeys. Apes have a broader chest, a larger brain-to-body size ratio, and more mobile shoulder joints that allow them to swing through trees (a form of locomotion called brachiation). Monkeys are typically smaller, with a narrower chest, and are better suited for running and leaping on top of branches.  

When it comes to movement monkeys are mostly quadrupedal, meaning they walk on all four limbs, often running along branches. Apes, because of their broad chest and flexible shoulders, can walk upright for short distances, and many are known for knuckle-walking.

When it comes to facial features, Apes often have flatter faces with a wide range of expressive features, which allows for complex social communication. Monkeys tend to have longer snouts and less expressive faces.  

Apes are generally considered more intelligent than monkeys. They have larger brains and exhibit more complex cognitive abilities, including problem-solving, abstract thinking, and self-awareness (many can recognize themselves in a mirror).  

Both monkeys and apes are highly social, but apes tend to have more complex social structures with hierarchies and alliances. Great apes also form strong family units and display a high degree of empathy and social learning.

They usually have a longer lifespan then a monkey and usually only have one baby at a time.

Some people find it hard to get their head around the fact that chimpanzees are not monkeys but are part of the ape family.

More next week

Monkey’s

~ joannerambling ~ 2 Comments

Today’s topic is monkeys, so what is a monkey, well a monkey is a tailed primate, excluding lemurs, tarsiers, and lorises. They are different from apes because apes do not have tails. Monkeys have narrow chests and specific skeletal features that distinguish them from apes. Most monkey species, of which there are nearly 200, reside in tropical forests and move on all four limbs.

Monkeys are divided into two main groups: Old World and New World monkeys. Old World monkeys belong to the family Cercopithecidae, while New World monkeys are platyrrhines, comprising five families. These groups are distinguished by their noses: New World monkeys have broad noses with wide septums and outward-facing nostrils, while Old World monkeys have narrow noses with thin septums and downward-facing nostrils.

Most monkeys have good problem-solving skills and can learn from experience, but they do not reach the cognitive levels of great apes. Monkeys are highly social animals that live in troops.

Monkeys are found in the wild in many countries across Africa, Asia, and the Americas. While they are most prevalent in tropical rainforests, some species have adapted to live in other environments, including snowy mountains and urban areas.  

How long do they live well that differs depending on the species, their environment (wild vs. captivity), and other factors. However, in general in the wild most live between 15-30yrs, baboons, can live up to 40yrs.

Monkeys in captivity often live much longer than their wild counterparts due to protection from predators, disease, and competition for food. It’s common for monkeys in zoos or research centres to live well into their 30’s or 40’s.

Monkeys are highly adaptable omnivores, and their diet can vary significantly depending on the species, their habitat, and the season. While the image of a monkey eating a banana is iconic, it’s not a primary food source for many wild species, and their diets are much more diverse.  

They are opportunistic eaters, and their diet reflects their ability to adapt to their surroundings and take advantage of any available food source. They eat a large variety of fruits and not just bananas, they also eat berries, mangos and figs to name a few. They also eat nuts and seeds, some are able to crack open hard nuts and seeds.

Many monkeys, especially larger species like howler monkeys and colobus monkeys, have specialized digestive systems to process fibrous plant material.  

They get crucial protein from a variety of animal sources, such as invertebrates like ants, termites, caterpillars, and spiders, as well as small vertebrates like lizards, frogs, bird eggs, and even small birds and rodents.  

Elephants

~ joannerambling ~ 4 Comments

Today we are looking at elephants which are the largest living land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant.

African elephants are the largest land animals, with males reaching up to 13 feet tall and weighing up to 14,000 pounds. 

The trunk is a multi-functional organ, used for breathing, smelling, touching, drinking, and even as a tool for digging and grabbing.

They have tusks, which are actually elongated incisor teeth that grow throughout their lives. 

While their skin is thick, it’s also sensitive and elephants often use mud and dust to protect themselves from the sun and insects. 

They are known to have an exceptional memory and are known to remember individuals and locations for years. 

They live in close-knit herds, primarily led by older females, and communicate through various vocalizations and body language. 

They communicate using a range of sounds, including trumpeting and infrasound, which can travel long distances.

African elephants are pregnant for an average of 22 months, whilst for Asian elephants it’s 18 to 22 months.1 You might think such a long pregnancy is because of what huge creatures they are – but you’d only be partly correct. Baby elephants do develop slowly in the womb because of their physical size but also because of the size of their intellect.

Baby elephants can stand and walk within minutes of birth, and they stay close to their mothers for support and protection. 

Both African and Asian elephants are facing threats from habitat loss and poaching, leading to conservation efforts to protect them. 

They can live almost as long as humans, African elephants have a maximum lifespan of about 74 years, Asian elephants can live to about 80 and the oldest known elephant in the world is thought to be an Asian elephant who lived to be 89 in captivity. 

Giant Panda

~ joannerambling ~ 2 Comments

This week we are looking at the giant panda, which is a bear, I never thought of them as being part of the bear family.

Giant pandas belong to the bear family, whereas red pandas are in their own family, and they are more closely related to raccoons. Interestingly, giant pandas are more closely related to polar bears than to red pandas.

Giant pandas are typically 4 to 6 feet long and stand 2 to 3 feet tall at the shoulder. They can weigh between 220 and 330 pounds, with males tending to be larger than females,  Newborn pandas are very small, about the size of a stick of butter. 

Giant pandas live in the mountain ranges of southwestern China, specifically in the provinces of Sichuan, Shaanxi, and Gansu. They inhabit bamboo forests at elevations between 5,000 and 10,000 feet. Their habitat is characterized by humid, wet conditions and is often shrouded in mist and clouds.

A panda’s daily diet consists almost entirely of the leaves, stems and shoots of various bamboo species. Bamboo contains very little nutritional value so pandas must eat 12-38kg every day to meet their energy needs.

Scientists are not sure how long giant pandas live in the wild, but they are sure it is shorter than lifespans in zoos. They estimate that lifespan is about 15-20 years for wild pandas and about 30 years for those in human care. Chinese scientists have reported zoo pandas as old as 35.

Pandas are dependent on their mothers for the first few months of their lives and are fully weaned at 8 to 9 months. Most pandas leave their mothers when she becomes pregnant again, usually at about 18 months. Gestation takes from 95-160 days. Pandas normally give birth to single young. Twins seem to be born more frequently in captivity, when artificial insemination is used. The reproductive rate is about 1 cub every 2 years.

They are friendly and cheerful, Pandas have bundles of energy and warmth. They are confident and love trying out new things. Sociable and party-loving, they enjoy seeing friends and often put their friends’ feelings ahead of their own.

While pandas are known for their clumsy and lazy behaviour often observed in captivity or during feeding, they are actually proficient tree climbers and swimmers. 

There are the only two panda species found the giant and the red.. Despite their similarity in name, the two are not scientifically connected. They share the same geographical area and similar food.

Andean or Spectacled Bear

~ joannerambling ~ Leave a comment

This week we are looking at the Andean Bear also known as the Spectacled Bear, this is a species of bear native to the Andes Mountains in northern and western South America. It is the only living species of bear native to South America, and the last remaining short-faced bear.

The bears are an endangered species, listed as Vulnerable, and it is illegal to kill them. The Andean bear is the last remaining short-faced bear spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae.

They are technically the largest land carnivore on that continent, although as little as 5% of its diet is composed of meat. South America’s largest obligate carnivore is the jaguar. Among South America’s extant, native land animals, only the Baird’s and South American Tapirs are heavier than this species. They are a mid-sized species of bear.

Overall, its fur is blackish in colour, though bears may vary from jet black to dark brown and to even a reddish hue. The species typically has distinctive, beige-coloured marking across its face and upper chest, though not all Spectacled bears have “spectacle” markings. The pattern and extent of pale markings are slightly different on each individual bear and bears can be readily distinguished by this.

They are relatively small compared to other bear species. 

Males typically weigh between 220-440 pounds and are 5.5 to 6.5 feet long, while females weigh between 80-180 pounds and are slightly smaller. They stand 2 to 3 feet tall at the shoulder. 

They have relatively large heads compared to their body size, as well as powerful claws and paws that help them climb trees and build nests.  Despite their size, they are known for their adaptability to different environments within the Andes, from cloud forests to coastal deserts. 

They inhabit mountainous regions of South America, primarily the Andes Mountains, from Venezuela to Bolivia. They are found in a variety of habitats including rainforests, cloud forests, grasslands, and even scrublands. They are known to build platform nests in trees for eating and sleeping and are generally active year-round.

They feed on fruits and bromeliads being there favored foods, but also eat berries, grasses, bulbs, cactus flowers and small animals such as rodents, rabbits and birds. Near settlements, bears sometimes raid cornfields. Andean bears climb trees and forage on the ground.

They have a lifespan of around 20yrs in the wild but up to about 38yrs under human care they have a gestation of between 160 to 255 days and can have between 1 and 4 cubs they are considered mature between 4 and 7 years.

They are the only bears are the only known to eat bromeliads. Has rings of white or light fur around its eyes. The rest of the bear’s fur is black or dark brown.

Andean bears, also known as spectacled bears, are generally considered one of the least aggressive bear species towards humans. While they are capable of defending themselves if threatened, they typically avoid encounters with people and are known for their shy and elusive nature. Attacks on humans are rare, with only one confirmed human death attributed to a spectacled bear. They can run up to 30 mph.

Asiatic Black Bear

~ joannerambling ~ 4 Comments

This week’s bear is the Asiatic Black Bear, these bears can be found in eastern Asia including Afghanistan, Bangladesh, Bhutan, Cambodia, China, India, Islamic Republic of Iran, Japan, Democratic People’s Republic of Korea, Lao People’s Democratic Republic, Malaysia, Mongolia, Myanmar, Nepal, Pakistan, Russian Federation, Taiwan and Vietnam.

They have long black fur with a distinct white patch on the ch

est that is often crescent-shaped. The fur around the shoulders and throat is particularly long, and their ears are relatively large. The tail is short and is barely visible under a long, coarse coat. The black pelage has a light beige to white “V” shape on the chest area, a small beige to white coloured crescent across the throat, and a small spot of white on the chin. The white fur on the muzzle seldom reaches the orbits of the bear. 

The size differs between males and females. Males typically weigh 110 to 150 kg, while females weigh 65 to 90 kg. The head and body measure 120 to 180 cm in length, while the tail is an additional 6.5 to 10.6 cm. The head is large and rounded, and the eyes are small. The ears are large and are set farther apart than on an American black bear. The body is heavy, the legs are thick and strong, and the paws are broad.

They are more carnivorous than their American counterparts, although only a small part of their diet is made up of meat. This includes small mammals, birds, fish, molluscs and carcasses. They also feed on grasses, fruits, berries, seeds, insects and honey. In autumn they fatten up for the winter by feeding on nuts. In northern climates they hibernate. In southern climates they do not hibernate.

Little is known about Asiatic black bears in the wild; most of what is known about their social and reproductive behaviour has been collected by observing the bears in zoos and environments other than their natural habitat.

In captive environments, the mating pattern of Asiatic black bears is classified as promiscuous. The gestation period is typically 6 to 8 months. This period includes a period of delayed implantation, where the fertilized egg floats freely in the uterus for a time before attaching to the uterine wall and developing further. 

In the wild, Asiatic black bears typically forage alone. However, during breeding season, pairs can be seen hunting and gathering together.

They have a lifespan on around 25yrs in the wild and around 35-40yrs in captive.

They are listed as “Vulnerable” by the IUCN, meaning they face a high risk of extinction in the wild. Their populations are decreasing due to habitat loss, poaching, and the illegal trade of bear parts, particularly bile for traditional medicine. Here are some regional estimates of numbers:

  • China: Estimates range from 16,000 to 50,000. 
  • Japan: Estimates range from 12,000 to 20,000. 
  • India: Estimates range from 5,000 to 7,000. 
  • Russia: Estimates range from 5,000 to 7,000. 
  • Iran: Around 100-200. 
  • South Korea: Approximately 40, following reintroduction efforts

They are generally considered dangerous to humans, with documented cases of both unprovoked and provoked attacks. While they are not as frequently involved in attacks as some other bear species, they are known to raid crops, damage property, and injure or kill people. Attacks are more common during late summer, coinciding with mating season.
