Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species , between the sexes and depending on age and ...
The current population of wild kagus is about 250–1000 birds, and the species is the focus of a decades-long conservation effort. The kagu's initial decline was caused by subsistence hunting. The bird was trapped extensively for the European pet trade [5] and for museums and zoos until it was afforded protection. [14]

The long-tailed mockingbird is 27 to 29.5 cm (10.6 to 11.6 in) long and weighs 54 to 79 g (1.9 to 2.8 oz) with an average of 66.6 g (2.35 oz). Males are slightly larger than females. Adults of the nominate subspecies have a broad white supercilium and a black stripe through the eye that touches a black patch on the white cheek. Their crown and ...
