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 ...
Butterflying pork loin. Butterflying is a way of preparing meat, fish, or poultry for cooking by cutting it almost in two, but leaving the two parts connected; it is then often boned and flattened. [ 1] Spatchcocking is a specific method for butterflying poultry that involves removing the backbone, and spatchcock as a noun may refer to a bird ...
An adult bird which has been beak-trimmed as a chick. Beak trimming (also spelled as beak-trimming; informally as debeaking), or beak conditioning, is the partial removal of the beak of poultry, especially layer hens and turkeys, although it is also be performed on some quail and ducks. When multiple birds are confined in small spaces due to ...
African fish eagle in Lake Zway, Ethiopia. The African fish eagle is a large bird. The female, at 3.2–3.6 kg (7.1–7.9 lb) is larger than the male, at 2.0–2.5 kg (4.4–5.5 lb). This is typical sexual dimorphism in birds of prey. Males usually have wingspans around 2.0 m (6.6 ft), while females have wingspans of 2.4 m (7.9 ft).

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.
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]
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 .
