The black-chinned hummingbird (Archilochus alexandri) is the bird species known to have the smallest genome among birds, which is only 0.91 Gb long.The genomic evolution of birds has come under scrutiny since the advent of rapid DNA sequencing, as birds have the smallest genomes of the amniotes despite acquiring highly derived phenotypic traits.
Evolution generally occurs at a scale far too slow to be witnessed by humans. However, bird species are currently going extinct at a far greater rate than any possible speciation or other generation of new species [citation needed]. The disappearance of a population, subspecies, or species represents the permanent loss of a range of genes.
A turning point came in the early twentieth century with the writings of Gerhard Heilmann of Denmark.An artist by trade, Heilmann had a scholarly interest in birds and from 1913 to 1916, expanding on earlier work by Othenio Abel, [12] published the results of his research in several parts, dealing with the anatomy, embryology, behavior, paleontology, and evolution of birds.

Chukar Patridge from United Arab Emirates. The chukar partridge (Alectoris chukar), or simply chukar, is a Palearctic upland gamebird in the pheasant family Phasianidae.It has been considered to form a superspecies complex along with the rock partridge, Philby's partridge and Przevalski's partridge and treated in the past as conspecific particularly with the first.
