Xingu Screech Owl
The Xingu screech owl (''Megascops stangiae'') is a species of owl in the family Strigidae. It is found only in the Tapajos-Xingu and Xingu-Tocantins of Brazil. The holotype was collected in Serra dos Carajás. It is closely related to tawny-bellied screech owl in both morphology and genetics, but could be differed by its longer song pace. This species was described in 2021, and thus recognized in Avibase Avibase is an online taxonomic database that organizes bird taxonomic and distribution data globally.

Strigidae
The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genera. The typical owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J. S.; Cannings, R.J. and Mikkola, H. (1999). "Family Strigidae (Typical Owls)". ''In'' del Hoyo, J.; Elliot, A. & Sargatal, J. (eds.) (1999). ''Handbook of the Birds of the World.

Tapajós–Xingu Moist Forests
The Tapajós–Xingu moist forests (NT0168) is an ecoregion in the eastern Amazon basin. It is part of the Amazon biome. The ecoregion extends southwest from the Amazon River between its large Tapajós and Xingu tributaries. Location The Tapajós–Xingu moist forests lie between the Tapajós river to the west and the Xingu rivers to the east, tributaries of the Amazon River to the north. They have an area of . The rivers act as barriers to the movement of plants, animals and insects to and from adjacent regions. In the south the rugged Serra do Cachimbo divides the ecoregion from other moist forest areas. There are urban centers at Santarém at the mouth of the Tapajós, Aveiro on the lower Tapajós and Altamira on the Iriri River. The ecoregion is crossed by the Trans-Amazonian Highway (BR-230) and the BR-163 highway from Santarém to Cuiabá. To the northwest the ecoregion adjoins the Madeira–Tapajós moist forests on the other side of the Tapajós River. To the north it ...

Xingu–Tocantins–Araguaia Moist Forests
The Xingu–Tocantins–Araguaia moist forests (NT0180) is an ecoregion in the eastern Amazon basin. It is part of the Amazon biome. The ecoregion is one of the most severely degraded of the Amazon region, suffering from large-scale deforestation and selective extraction of timber, particularly along the Trans-Amazonian Highway and in the higher and more populated southern portions. Location The Xingu–Tocantins–Araguaia moist forests ecoregion has an area of . It lies to the south of the Amazon River in eastern Brazil. The Xingu River defines the western boundary and the Tocantins River defines the eastern boundary. To the south the ecoregion rises into the Carajás Mountains, where it becomes interspersed with areas of seasonal forest and cerrado. Population centers include São Félix do Xingu on the Xingu, Porto de Moz, Oeiras do Pará and Gurupá on the Amazon, and Marabá on the Tocantins. The Marajó várzea at the mouth of the Amazon lies to the north. To the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tawny-bellied Screech Owl
The tawny-bellied screech owl (''Megascops watsonii'') is a species of owl in the family Strigidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.Holt, D. W., R. Berkley, C. Deppe, P. L. Enríquez, J. L. Petersen, J. L. Rangel Salazar, K. P.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the con ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megascops
Screech owls are typical owls ( Strigidae) belonging to the genus ''Megascops'' with 23 living species. For most of the 20th century, this genus was merged with the Old World scops owls in ''Otus'', but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data. Screech owls are restricted to the Americas. Some species formerly placed with them are nowadays considered more distinct (see below for details). Description Similar to other owls, the screech owl females are larger than the males of their species. They have a compact size and shape. They are small and agile, and about 7 to 10 inches tall and have a wingspan around 18 to 24 inches. They have prominent, wide-set feather tufts with bright yellow/green eyes. They have different brownish hues with whitish, patterned underside. This coloration helps them get camouflage against the tree bark. Ecology and behavior Screech owls hunt from perches in ...

Birds Of Brazil
Brazil has one of the richest bird diversities in the world. The avifauna of Brazil include a total of 1858 confirmed species of which 238 are endemic. Five have been introduced by humans, 96 are rare or vagrants, and five are extinct or extirpated. An additional 14 species are hypothetical (see below). Brazil hosts about 60% of the bird species recorded for all of South America. These numbers are still increasing almost every year, due to new occurrences, new species being described, or splits of existing species. About 10% of the bird species found in Brazil are, nonetheless, threatened. In June 2013 a simultaneous discovery of fifteen bird species in Brazil was announced, the first such since 1871, when August von Pelzeln described forty new species. The birds were from the families Corvidae, Thamnophilidae, Dendrocolaptidae, Tyrannidae, and Polioptilidae. Eleven of the new species are endemics of Brazil and four also inhabit Peru and Bolivia.
