Like most versions until the late 19th century, it had only the first stanza and dealt with a hare, not a fish, with the words: One, two, three, four and five, I caught a hare alive; Six, seven, eight, nine and ten, I let him go again. [1] The modern version is derived from three variations collected by Henry Bolton in the 1880s from America. [1]
Wing clipping. Wing clipping is the process of trimming a bird's primary wing feathers or remiges so that it is not fully flight-capable, until it moults, sheds the cut feathers and grows new ones. This procedure is usually carried out by avian veterinarians, breeders, or the bird's owners, and primarily on pet birds like parrots.
Flying fish use their pectoral fins to glide above the water's surface. Certain species of fish and birds are able to locomote in both air and water, two fluid media with very different properties. A fluid is a particular phase of matter that deforms under shear stresses and includes any type of liquid or gas.

The tools, on average, were about 60 cm (24 in) long and 1.1 cm (0.4 in) in circumference. The chimpanzee then jabbed the spear into hollows in tree trunks where bushbabies sleep. [ 37 ] There was a single case in which a chimpanzee successfully extracted a bushbaby with the tool.
Birds and mammals (including humans) normally adjust focus by changing the shape of their lens, but fish normally adjust focus by moving the lens closer to or further from the retina. Fish retinas generally have both rod cells and cone cells (for scotopic and photopic vision ), and most species have colour vision .
Aquatic locomotion. A great cormorant swimming. Aquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals.
There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge. [1] Which techniques are appropriate is dictated mainly by the target species and by its habitat. [2]
