Wing morphology correlates with flight performance and ecology among adult birds, yet the impact of wing development on aerodynamic capacity is not well understood. Recent work using chukar partridge (Alectoris chukar), a precocial flier, indicates that peak coefficients of lift and drag (C(L) and C(D)) and lift-to-drag ratio (C(L):C(D)) increase throughout ontogeny and that these patterns corr...

The Chukar Partridge (Alectoris chukar, Galliformes) is one of the most important game birds in its native range, spanning from Balkans to eastern Asia, and regions Europe, North America New Zealand where it was introduced. Previous studies found two main genetic lineages species forming an a western clade. Partridges are raised farms released supplement natural populations for shooting USA, Ca...

Present paper reports Home range and distance covered of Chukar partridge at mandal valley, Garhwal Himalaya from November 2018 to October 2019. During the study period, average home (altitude M) was 1756.75±7.75 water source 69.52±6.76 (M), maximum observed in month June (1812±8.0) while minimum (1708±5.0) respectively. Maximum August (99.04±11.42) recorded May (41.10±4.83). Seasonal variation...

The propagule pressure hypothesis asserts that the number of individuals released is the key determinant of whether an introduction will succeed or not. It remains to be shown whether propagule pressure is more important than either species-level or site-level factors in determining the fate of an introduction. Studies claiming to show that propagule pressure is the primary determinant of intro...

Introduction: Phasianidae is a non-migratory group of birds belonged to partridges family. One of the well-known species of partridge is Alectoris chukar, which is a medium-sized bird, larger than quails and smaller than pheasants. They are native to Asia, Africa, Europe and the Middle East and belong to the category of gallinaceous birds. Understanding the physiology and immunology of the lymp...
