Gamebird hybrids
Encyclopedia
Gamebird hybrids are the result of crossing species of game birds, including ducks, with each other and with domestic poultry. These hybrid species may occur both naturally or though the intervention of man.
Charles Darwin
described hybrids of game birds and domestic fowl in The Variation of Animals And Plants Under Domestication
:
Hybrids have been obtained between the "ornamental" species of pheasants e.g. Lady Amherst's, Silver and Reeves Pheasants.
Natural pheasant
and grouse
hybrids have been reported:
Charles Darwin mentioned crosses between domestic fowl and pheasants in Origin of Species
(top of this page), where he mentioned effeminate behaviour in the male hybrids.
In her book Bird Hybrids, A. P. Gray lists numerous crosses between chicken
s (Gallus gallus) and other types of fowl. Domestic fowl can be crossed, and produce fertile offspring, with Silver Pheasant
s, Red Junglefowl
and Green Junglefowl
. They have also produced hybrids with peafowl
, chachalaca
s, Capercaillie
, Grouse
, Quail
, curassows
, pheasant
s and guans
.
Domestic fowl have been crossed with guineafowl
and also with Common Pheasant
(Phasianus colchicus). Domestic Fowl/Pheasant hybrids have also occurred naturally. Domestic chickens and quail (Coturnix coturnix subsp. japonica) have been hybridised using artificial insemination
.
The Peafowl
(Pavo cristatus) from Asia and the Common Guinea fowl (Numida meleagris) from Africa have been crossed.
female turkeys, both male and female embryos form, but the males are much less viable and usually die in the early stages of development. When male turkeys inseminated female chickens, no hybrids resulted although the unfertilised chicken eggs began to divide. According to Olson turkey-chicken crosses produced all males.
A supposed Turkey x Pheasant hybrid was reported by Edwards in 1761.
Charles Darwin
also described duck hybrids in The Variation of Animals And Plants Under Domestication:
Hybrids between mallard
ducks and Aylesbury ducks (a white domestic breed derived from the mallard) are frequently seen in British parks where the two types are present. The hybrids often resemble a dark coloured mallard with a white breast. Mallard ducks also hybridise with the Muscovy duck producing pied offspring.
Hybrids between the Ruddy Duck
and White-headed Duck
are undesirable in parts of Europe
http://www.wwt.org.uk/threatsp/hybrid/spain.htm http://www.rspb.org.uk/policy/species/ruddyduck/problem.asp where the introduced Ruddy Duck has bred with native White-headed ducks. The increasing number of Ruddy ducks and hybrids threatens the existence of the White-headed ducks, resulting in shooting campaigns to remove the introduced species. This is controversial as some believe that nature should be allowed to take its course, even though this favours the more successful introduced species

In the Convention on Biological Diversity a domesticated species is defined as a 'species in which the evolutionary process has been...

Mr. Hewitt, who has had great experience in crossing tame cock-pheasants with fowls belonging to five breeds, gives as the character of all 'extraordinary wildness' (13/42. 'The Poultry Book' by Tegetmeier 1866 pages 165, 167.); but I have myself seen one exception to this rule. Mr. S. J. Salter (13/43. 'Natural History Review' 1863 April page 277.) who raised a large number of hybrids from a bantam-hen by Gallus sonneratii, states that 'all were exceedingly wild.' [...] utterly sterileInfertilityInfertility primarily refers to the biological inability of a person to contribute to conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term...
male hybrids from the pheasant and the fowl act in the same manner, "their delight being to watch when the hens leave their nests, and to take on themselves the office of a sitter." (13/57. 'Cottage Gardener' 1860 page 379.) [...] Mr. Hewitt gives it as a general rule with fowls, that crossing the breed increases their size. He makes this remark after stating that hybrids from the pheasant and fowl are considerably larger than either progenitor: so again, hybrids from the male golden pheasant and female common pheasant "are of far larger size than either parent-bird.' (17/39. Ibid 1866 page 167; and 'Poultry Chronicle' volume 3 1855 page 15.)"

There have been attempted crosses between domestic turkeys (Meleagris gallapavo) and chickens. According to Gray in 12 studies no hybrids hatched. Other reports found only a few fertile eggs were produced and very few resulted in advance embryos. According to Olsen, 23 hybrids were obtained from 302 embryos which resulted from 2132 eggs.

Hybrids are often raised between the common and musk duck, and I have been assured by three persons, who have kept these crossed birds, that they were not wild; but Mr. Garnett (13/45. As stated by Mr. Orton in his 'Physiology of Breeding' page 12.) observed that his hybrids were wild, and exhibited 'migratory propensities' of which there is not a vestige in the common or musk duck.
