==== Negative impacts on other birds ==== There are a number of negative effects of common pheasants on other game birds, including: [[Brood parasite|nest parasitism]], disease, aggression, and competition for resources.<ref name=":0">{{Cite book |last1=Hallett |first1=Diana L. |last2=Edwards |first2=William R. |last3=Burger |first3=George V. |url=http://worldcat.org/oclc/19288751 |title=Pheasants : symptoms of wildlife problems on agricultural lands |date=1988 |publisher=North Central Section of the Wildlife Society |oclc=19288751}}</ref> Nest parasitism, or [[Brood parasite|brood parasitism]], is common in pheasants because of their propensity to nest near other birds and the fact that nesting requirements are similar to those of other prairie birds and [[waterfowl]] that inhabit the same areas. This phenomenon has been observed in [[grey partridge]]s; [[Tympanuchus|prairie chicken]]s; several types of [[duck]], rail, [[grouse]], [[Turkey (bird)|turkey]]s, and others.<ref name=":0" /> Effects of nest parasitism may include abandonment of nests with a high proportion of foreign eggs, lower hatching rates, and lower numbers of eggs laid by the host species. Pheasant eggs also have a shorter incubation time than many of their nestmates, which may result in the individual watching over the nest to abandon her own eggs after the pheasants hatch, thinking that the remaining eggs are not viable.<ref name=":0" /> Pheasants raised in other species' nests often imprint on their caretaker, which may result in them adopting atypical behaviour for their species. This is sometimes the cause of hybridisation of species as pheasants adopt the mating behaviour of their nest's host species.<ref name=":0" /> Pheasants often compete with other native birds for resources. Studies have shown that they can lead to decreased populations of [[Colinus|bobwhite]]s and [[partridge]]s due to habitat and food competition.<ref>{{Cite journal|last=Errington|first=Paul L.|date=1945-01-01|title=Some Contributions of a Fifteen-Year Local Study of the Northern Bobwhite to a Knowledge of Population Phenomena|url=http://dx.doi.org/10.2307/1943293|journal=Ecological Monographs|volume=15|issue=1|pages=2β34|doi=10.2307/1943293|jstor=1943293|bibcode=1945EcoM...15....1E |issn=0012-9615}}</ref> Insects are a valuable food source for both pheasants and partridges and competition may lead to decreased populations of partridges.<ref>{{Cite journal|last=Potts|first=G.

While pheasants tolerate the infection well, other birds such as [[ruffed grouse]], [[Chukar partridge|chukar]], and grey partridge are highly susceptible.<ref>{{Cite journal|last1=Lund|first1=Everett E.|last2=Chute|first2=Anne M.|date=January 1972|title=The Ring-Necked Pheasant (Phasianus colchicus torquatus) as a Host for Heterakis gallinarum and Histomonas meleagridis|url=http://dx.doi.org/10.2307/2423877|journal=American Midland Naturalist|volume=87|issue=1|pages=1β7|doi=10.2307/2423877|jstor=2423877|issn=0003-0031|url-access=subscription}}</ref> Pheasants also have a tendency to harass or kill other birds. One study noted that in pheasant vs. prairie chicken interactions, the pheasants were victorious 78% of the time.<ref>{{Cite book |last1=Vance |first1=D.Russel |last2=Westemeier |first2=Ronald L. |url=http://worldcat.org/oclc/870462218 |title=Interactions of Pheasants and Prairie Chickens in Illinois. |date=1979 |oclc=870462218}}</ref>
