Ever think about which one is the largest bird in the world? Some birds can fly and some of them cannot. While being largest also meant it’s harder to fly – then the few largest birds also fall in the categories of the flightless bird.

But before we go through more details you might need to check the flying birds ever – where some of the largest flying birds already extinct. Because it’s not the size of the bird that restrict them from flying – but their physical and the volume of their flying muscles.

The largest birds fall from both categories of flying and flightless birds. From the list we can go further details about their nature of the lives that explains more about their physical shapes. While in this article today we just want to know which birds include in this category.

Below are the 10 largest birds that still exist today:

Beautiful Sound of Superb Lyrebird

Most of the birds have beautiful colours and shapes, but when it comes to Superb Lyrebird there are more qualities to be looked at: the super skill of mimicking sounds rather than just unique plumes that gave them their name.

Lyrebird has two species of ground-dwelling Australian birds. They are from genus Menura, and the family of Menuridae. The male Superb Lyrebird has a beautiful tail feathers that they will fanned out in courtship display. Two of its tail feathers are curved, in display it resembles the shape of a lyre.

The two species of lyrebirds are superb lyrebird (Menura novaehollandiae), and Albert’s lyrebird (Menura alberti). Both species inhabit the areas of the south-eastern Australian mainland and southern Tasmania. They are ground-dwelling species in the moist forest, yet they still roost in trees at night. They rarely move far from their areas that usually within a range of 10 km in diameter.

Superb lyrebird popular with its ability to mimic other sounds, whether natural sounds or mechanical sounds. It is believed that 80% of its songs are the result of this mimicry. They sing throughout the year, with its peak during the breeding season, from June to August. They can sing for four hours a day. They have been recorded mimicking human sounds such as a mill whistle, a cross-cut saw, chainsaws, car engines and car alarms, fire alarms, rifle-shots, camera shutters, dogs barking, crying babies, music, mobile phone ring tones, and even the human voice.

As any ground-dwelling birds it mostly feed on insects such as cockroaches, beetles (both adults and larvae), earwigs, fly larvae, and the adults and larvae of moths. Other preys include centipedes, spiders, and worms. Less commonly prey on stick insects, bugs, amphipods, lizards, frogs and occasionally, seeds. It finds food by scratching with its feet through leaf-litter. Lyrebird tends to forage alone, while females and young males may be seen feeding together.

Lyrebirds are not endangered in its natural areas. Albert’s lyrebird however, had been listed as vulnerable by the ICUN, but then with carefully managed habitat, the species was re-assessed to near threatened in 2009. Nowadays superb lyrebird is classified as common. Their main predators include cats and foxes, other than increasing in human populated areas.

More About Salmon

Salmon is one of the fish largely farmed these days. The farming technologies help more people from all around the world to enjoy eating salmon at the same time avoiding wild salmon to recover from overfishing, loss of habitats due to dam constructions deforestation and development. No one knew the exact numbers of the ideal salmon in the wild, but avoiding further damage to the wild population in important before it’s too late.

There are more interesting things about salmon that we need to know. As the salmon that grows for commercial purposes only few types that suitable for the farming industries. While there are many other salmons included in this family and some of them not even migrate to the sea as other salmon do. So what happen to them? Are all of them threaten as the common salmon (Atlantic salmon: Salmo salar and Pacific salmon: genus Oncorhynchus)?

Salmon is the group of fish in the family Salmonidae that also includes trout, char, grayling and whitefish. But the salmon that we are going to talk about are mostly the two popular group of North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus) and few more species in the same family.

The main group of salmons show in the table below with their genus, names, scientific names, maximum length, common length, maximum weight, and maximum age. These are also the salmons that use as farming salmon for commercial purposes. From their maximum age, we will know their life cycles and how long it would take for the salmon to restore their population.

Genus	Common name	Scientific name	Maximum length	Common length	Maximum weight	Maximum age
Salmo (Atlantic salmon)	Atlantic salmon	Salmo salar Linnaeus, 1758	150 cm	120 cm	46.8 kg	13 years
Oncorhynchus (Pacific salmon)	Chinook salmon	Oncorhynchus tshawytscha (Walbaum, 1792)	150 cm	70 cm	61.4 kg	9 years
	Chum salmon	Oncorhynchus keta(Walbaum, 1792)	100 cm	58 cm	15.9 kg	7 years
	Coho salmon	Oncorhynchus kisutch(Walbaum, 1792)	108 cm	71 cm	15.2 kg	5 years
	Masu salmon	Oncorhynchus masou(Brevoort, 1856)	79 cm	cm	10.0 kg	3 years
	Pink salmon	Oncorhynchus gorbuscha (Walbaum, 1792)	76 cm	50 cm	6.8 kg	3 years
	Sockeye salmon	Oncorhynchus nerka(Walbaum, 1792)	84 cm	58 cm	7.7 kg	8 years

Other than the main species of salmons there are few more salmon that we should know;

• Black Sea salmon (Salmo labrax) - small species of salmon with 51 cm (20 in) in length on average and can reach up to 76 cm (30 in). This species inhabits the northern Black Sea coast and inflowing river. Same as other salmon they are also anadromous, lacustrine and resident river populations. Spawn in October - January. Parrs live in rivers for 2 - 4 years, then smoltify and migrate to the sea or mature in the freshwater. They can spend for another 2 - 4 years before return to the spawning areas. Their conservation status also showing least concern.
• Danube salmon (Hucho hucho) - also known as huchen, is a large freshwater fish. They never go to the sea as any other salmon. Huchen is endemic to the Danube basin in Europe. They also reported to be found in the Dniestr basin in the historic time and in big dam reservoirs on the mountain such as Lake Czorsztyn in Poland. Huchen is a big fish with size up to 1.5 m (4ft 11 in) and weight up to 50 kg 110 lb). The modern record for largest huchen is 34.8 kg (77 lb), caught in February 1985 in Spittal an der Drau in Austria, while older records reported weights in excess of 60 kg (130 lb). Unfortunately the conservation status for huchen already reach the level of “threatened”.
• Sabertooth salmon (Oncorhynchus rastrosus) - is an extinct species of salmon that can grow to very large sizes. They lived along the Pacific coast of North America in the late of Miocene Period, near California. The adults grew up to 2.7 m (9 ft) in length and also an anadromous like the modern salmon. They have a pair of small fangs protruding from the tip of the snout that also gave them their name. Even though so big they believe to be planktonic feeder. More about sabertooth salmon can be found here.

Yes there are many other fish in the same family of Salmonidae. If you want to know more details about the sub-species in this family the best place to look for them is through fishbase. While salmon farming get better in producing good quality of salmon every year and the wild salmon population getting increases. The sub-species of salmon too should be taken care off too. With more knowledge shares among publics the awareness of conservation will be taken more seriously by each individual.

How Nutrient From The Sea Ended Up In The Forest?

It’s hard to believe that trees deep in the forest get their nutrients far-far away from the sea. That what the wonder on nature when they work together accordingly. One of examples that we can see is the returning of salmon during the breeding season.

Salmon is one of few species of animals that start their life in the freshwater and spend their growing time in the sea then return back only to lay their eggs. As they return their journey back to the deep forest that might take few thousand kilometres as example of chum salmon (Oncorhynchus keta) that travel the longest journey far up to Yukon River and deep into the Amur River basin where the journey will take more than 3,200 km (2,000 mi).

Within their journey they will become meals for numbers of other animal species such as eagle, otter, water birds, and bear that waiting for their returning from the sea. Then for the surviving salmon will continue their journey to their breeding place far into the forest. Their journey up the river requires them to have strong muscles, with it they are capable to leaps more than 2 meters height.

Travelling far from the sea will make salmon lost lots of energy all of them will die after spawning their eggs. Their carcases might be taken by other animals out of the water and left the remaining alone. Then the remaining will become home to blow fly’s larvae that will eat on the remaining flesh.

Once they are ready, the maggots will buried themselves in the soil until they emerge as adult flies. These flies again will do another important thing for plants and trees in the surrounding areas; pollinating the flowers to make sure they can produce seeds for their next generation.

We might think that salmon just one species of animal and maybe important to those few animals that eat them. With closer observation we can see how all the ecosystem intertwine together with every single piece of them nourishing one another.

Even though each female salmon can carry from 2,500 to 7,500 eggs depending on size and species, only some of them will hatched. From that numbers less than 2 percent will return to the same location to spawn again in the next 6 to 7 years.
