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 ...
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).
Different terms have been given to the tool according to whether the tool is altered by the animal. If the "tool" is not held or manipulated by the animal in any way, such as an immobile anvil, objects in a bowerbird's bower, or a bird using bread as bait to catch fish, [7] it is sometimes referred to as a "proto-tool".

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.
Roseate spoonbill. The roseate spoonbill ( Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo .

The word is, more broadly, used as a pejorative [1] catch-all term for experimentation on live animals [2] [3] [4] by organizations opposed to animal experimentation, [5] but the term is rarely used by practising scientists. [3] [6] Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture. [7] [8]
[7] The term "fish" describes any non-tetrapod chordate, (i.e., an animal with a backbone), that has gills throughout life and has limbs, if any, in the shape of fins. [8] Unlike groupings such as birds or mammals, fish are paraphyletic, since the tetrapod clade is within the clade of lobe-finned fishes. [9] [10]
