The smallest bird in the world is the bee hummingbird (Mellisuga helenae). The 5-cm beauty is found in Cuba, where they call it “zunzuncito”. Other amazing facts:
+ Weighs less than 2 grams
+ Has the second fastest heart rate of all animals (1,260 BPM)
+ Has the highest body temperature of all birds (40 degrees Celsius)
+ Flaps its wing up to 200 times per second
The budgerigar a common pet parakeet or shell parakeet and informally nicknamed the budgie, is a small, long-tailed, seed-eating parrot. Budgerigars are the only species in the Australian genus Melopsittacus, and are found wild throughout the drier parts of Australia where the species has survived harsh inland conditions for the last five million years. Budgerigars are naturally green and yellow with black, scalloped markings on the nape, back, and wings, but have been bred in captivity with colouring in blues, whites, and yellows, greys, and even with small crests. Budgerigars are popular pets around the world due to their small size, low cost, ability to mimic human speech, and playful nature.
The Kea is a large species of parrot (superfamily Strigopoidea) found in forested and alpine regions of the South Island of New Zealand.
Kea loves to sit on the back of rodents (sheep,cows etc) and make holes on the back by puncturing it. After that it feed on the kidney fats of that animal. Amazing 😉
A 520-million-year-old fossil has provided evidence that complex brains evolved much earlier than previously thought. The 7.6-centimetre preserved skeleton belonged to Fuxianhuia protensa, an extinct invertebrate related to today’s spiders and insects, and contains remnants of optic nerves connected to a three-segment brain. This is the earliest known fossil to show a complex brain, according to the paper published in Nature.
Many species use built-in ferromagnets to detect their orientation with respect to the Earth’s magnetic field. Some species of birds, like the Arctic tern, make a 25,000 mile round-trip journey every year.
Don’t mess with the blue-ringed octopus – its neurotoxin can kill a human in minutes. But before it bites, releasing venomous saliva through its beak, the octopus sends out a warning—bright blue rings that suddenly iridesce all over its body. How? By flexing its muscles. The blue rings are always there, but pouches of skin conceal their iridescence when the octopus is relaxed.
