An argument, as it seems to me, of great weight, and applicable in several other cases, is, that the above-specified breeds, though agreeing generally in constitution, habits, voice, colouring, and in most parts of their structure, with the wild rock-pigeon, yet are certainly highly abnormal in other parts of their structure: we may look in vain throughout the whole great family of Columbidae for a beak like that of the English carrier, or that of the short-faced tumbler, or barb; for reversed feathers like those of the jacobin; for a crop like that of the pouter; for tail-feathers like those of the fantail.
From these several reasons, namely, the improbability of man having formerly got seven or eight supposed species of pigeons to breed freely under domestication; these supposed species being quite unknown in a wild state, and their becoming nowhere feral; these species having very abnormal characters in certain respects, as compared with all other Columbidae, though so like in most other respects to the rock-pigeon; the blue colour and various marks occasionally appearing in all the breeds, both when kept pure and when crossed; the mongrel offspring being perfectly fertile;--from these several reasons, taken together, I can feel no doubt that all our domestic breeds have descended from the Columba livia with its geographical sub-species.
Considering all the environments sampled, the families with the highest richness were Tyrannidae and Psittacidae, with 32 and 16 species, respectively, followed by Columbidae
, Picidae and Emberizidae, each with 13 species.
The results of this study show that pigeon adults in Algeria are infested with a multitude of parasites, as is the case for most Columbidae
in Europe [18,37], although the results show a high prevalence of lice and Low presence of other ectoparasites.
By quoting Shakespeare towards the end of this carefully structured oeuvre - "two strengthless doves will draw me through the sky" - he draws parallels with the portentous cooing of the collared Columbidae
and the lymphoma that laid low his father.

Like rest of the pigeons it is mainly herbivore, but it has adapted very well to the agricultural ecosystems, which provides it an agro-ecological feature different from other species of the family Columbidae
