The oxpeckers are two species of bird which make up the genus Buphagus, and family Buphagidae. The oxpeckers were formerly usually treated as a subfamily , Buphaginae, within the starling family, Sturnidae , but molecular phylogenetic studies have consistently shown that they form a separate lineage that is basal to the sister clades containing ...
Whatever the net result, mammals generally tolerate oxpeckers. [8] The yellow-billed oxpecker is 20 cm (7.9 in) long and has plain brown upperparts and head, buff underparts and a pale rump. The feet are strong. The adults' bills are yellow at the base and red at the tip, while juveniles have brown bills. [10] Its flight is strong and direct.
The preferred habitat is open country, and the red-billed oxpecker eats insects. Both the English and scientific names arise from this species' habit of perching on large wild and domesticated mammals such as cattle and eating ticks. [4] This species's relationship with rhinos gives the Swahili name Askari wa kifaru meaning "the rhino's guard". [5]
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be
Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
