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.

and Thraupidae were the most responsible, with 23.34, 19.27 and 17.11% respectively of consumption.
The largest numbers of species corresponded to the Tyrannidae (34), Emberizidae (25), Accipitridae (12), Icteridae (10), Psittacidae (9) and Columbidae
Birds that utilize forest into which chickens roam and that have ecologic behaviors that might put them at risk of coming into contact with poultry and poultry feces include ground birds (or those that spend a significant amount of time on the ground), such as Tynamidae (tinamous), Columbidae
(pigeons and doves), Thamnophilidae (antbirds, antshrikes), Caprimulgidae (nightjars and nighthawks), Furnariidae (foliage gleaners and leaf tossers), Formicaridae (antpittas), Emberizidae (finches and grassquits), or Turdidae (thrushes), and birds that might either consume chickens or aggregate near foodstuff consumed by chickens, such as Cathartidae (vultures), some members of Accipitridae and Falconidae (hawks, eagles, falcons), Cracidae (guans), and Odontophoridae (quails).
Las familias con mayor riqueza fueron: Tyrannidae (18 especies), Fumariidae (10 especies), Thraupidae y Columbidae
(ambas con seis especies).
