The beak, bill, or Rostrum (anatomy), rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, wikt:grasp#Verb, grasping, and holding (in wikt:probe#Verb, probing for food, eating, manipulating and carrying objects, predation, killing prey, or fighting), preening, Courtship in animals, courtship, and feeding young.

Western Gulf Coastal Grasslands
The Western Gulf coastal grasslands () are a tropical and subtropical grasslands, savannas, and shrublands, subtropical grassland ecoregion of the southern United States and northeastern Mexico. It is known in Louisiana as the "Cajun Prairie", Texas as "Coastal Prairie," and as the Tamaulipan pastizal () in Mexico. Setting The ecoregion covers an area of , extending along the shore of the Gulf of Mexico from southeastern Louisiana (west of the Mississippi Delta) through Texas and into the Mexican state of Tamaulipas as far as the Laguna Madre (Mexico), Laguna Madre. Specific areas include a number of barrier islands, and the ''Resaca (channel), resacas'' or natural levees of the Laguna Madre. The coast is vulnerable to tropical storms that can seriously damage habitats. This ecosystem, in part, has Edaphology, edaphic origins: the soils of this ecoregion are largely dominated by vertisol clays, the mechanical properties of which make it difficult for many tree species to grow an ...

Color Phase
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Laughing Gull
The laughing seagull (''Leucophaeus atricilla'') is a medium-sized gull of North America, North and South America. Named for its laugh-like call, it is an opportunistic omnivore and scavenger. It breeds in large colonies mostly along the Atlantic Ocean, Atlantic coast of North America, the Caribbean, and northern South America. The two subspecies are ''L. a. megalopterus'' — which can be seen from southeast Canada down to Central America — and ''L. a. atricilla'', which appears from the West Indies to the Venezuelan islands. The laughing seagull was long placed in the genus ''Larus'' until its present placement in ''Leucophaeus''. Taxonomy The laughing seagull was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Larus atricilla''.

Goat
The goat or domestic goat (''Capra hircus'') is a species of Caprinae, goat-antelope that is mostly kept as livestock.

It was one of the first animals to be domesticated, in Iran around 10,000 years ago. Goats have been used for milk, Goat meat, meat, Animal fur, wool, and Animal skin, skins across much of the world. Milk from goats is often turned into goat cheese, cheese. In 2022, there were more than 1.1 billion goats living in the world, of which 150 million were in India.
