How to draw Parrot for kids step by step
How to draw Parrot for kids - step by step - Fact - Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured.
How to draw Parrot for kids - step by step - Fact - Most parrots exhibit little or no sexual dimorphism. They form the most variably sized bird order in terms of length.
How to draw Parrot for kids - step by step - Fact - The most important components of most parrots' diets are seeds, nuts, fruit, buds and other plant material. A few species sometimes eat animals and carrion, while the lories and lorikeets are specialised for feeding on floral nectar and soft fruits.
How to draw Parrot for kids - step by step - Fact - Almost all parrots nest in tree hollows (or nest boxes in captivity), and lay white eggs from which hatch altricial (helpless) young.
How to draw Parrot for kids - step by step - Fact - Parrots, along with ravens, crows, jays and magpies, are among the most intelligent birds, and the ability of some species to imitate human voices enhances their popularity as pets.
How to draw Parrot for kids - step by step - Fact - Trapping wild parrots for the pet trade, as well as hunting, habitat loss and competition from invasive species, has diminished wild populations, with parrots being subjected to more exploitation than any other group of birds.[6]
How to draw Parrot for kids - step by step - Fact - Measures taken to conserve the habitats of some high-profile charismatic species have also protected many of the less charismatic species living in the same ecosystems.
How to draw Parrot for kids - step by step - Fact - Psittaciform diversity in South America and Australasia suggests that the order may have evolved in Gondwanaland, centred in Australasia. The scarcity of parrots in the fossil record, however, presents difficulties in confirming the hypothesis.
How to draw Parrot easy - step by step - Fact - A single 15 mm (0.6 in) fragment from a large lower bill (UCMP 143274), found in deposits from the Lance Creek Formation in Niobrara County, Wyoming, had been thought to be the oldest parrot fossil and is presumed to have originated from the Late Cretaceous period, which makes it about 70 Ma (million years ago).
How to draw Parrot easy - step by step - Fact - Other studies suggest that this fossil is not from a bird, but from a caenagnathid theropod or a non-avian dinosaur with a birdlike beak.
How to draw Parrot for Beginners - Fact - It is now generally assumed that the Psittaciformes, or their common ancestors with several related bird orders, were present somewhere in the world around the Cretaceous–Paleogene extinction event (K-Pg extinction), some 66 Ma.
How to draw Parrot for Beginners - Fact - If so, they probably had not evolved their morphological autapomorphies yet, but were generalised arboreal birds, roughly similar (though not necessarily closely related) to today's potoos or frogmouths (see also Palaeopsittacus below).
How to draw Parrot for Children - Fact - Though these birds (Cypselomorphae) are a phylogenetically challenging group, they seem at least closer to the parrot ancestors than, for example, the modern aquatic birds (Aequornithes). The combined evidence supported the hypothesis of Psittaciformes being "near passerines", i.e. the mostly land-living birds that emerged in close proximity to the K-Pg extinction.
How to draw Parrot for Children - Fact - Indeed, analysis of transposable element insertions observed in the genomes of passerines and parrots, but not in the genomes of other birds, provides strong evidence that parrots are the sister group of passerines, forming a clade Psittacopasserae, to the exclusion of the next closest group, the falcons.
