[ 1] Spatchcocking is a specific method for butterflying poultry that involves removing the backbone, and spatchcock as a noun may refer to a bird ...
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
A wing-clipped Meyer's parrot perching on a drawer handle. While clipping is endorsed by some avian veterinarians, others oppose it. [7]By restricting flight, wing clipping may help prevent indoor birds from risking injury from ceiling fans or flying into large windows, but no evidence shows that clipped birds are safer than full-winged ones, only that clipped birds are subject to different ...
Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. [1] Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn; and catadromous, in which adult fish live in fresh water and migrate into salt ...

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]
The food is mainly fish up to 12.5 cm (5 in) long, but the average size is 2.3 cm (7 ⁄ 8 in). [7] In Central Europe, 97% of the diet was found to be composed of fish ranging in size from 2 to 10 cm with an average of 6.5 cm (body mass range from <0.1 g to >10 g, average 3 g). [17] [18] Minnows, sticklebacks, small roach and trout are typical ...
The smallest species of kingfisher is the African dwarf kingfisher (Ispidina lecontei), which averages 10 cm (3.9 in) in length and between 9 and 12 g (0.32 and 0.42 oz) in weight. [16] The largest kingfisher in Africa is the giant kingfisher ( Megaceryle maxima ), which is 42 to 46 cm (17 to 18 in) in length and 255–426 g (9.0–15.0 oz) in ...
