Domestic hybrid (Khaki Campbell x Swedish)

We have a (Khaki Campbell x Swedish) ,identified by Liam!!

Oh yeah:)incredble beauty but massive problems allarround the globe,it's what i see

Thanks Antonio. I agree it is important to avoid loss of genetic diversity. Seems like a massive task though!

Emma,i copy this for you,if you seach about your zone i presume you find more info,maybee Liam noes something about

Abstract Abstract
The widespread occurrence of free-ranging domestic or feral carnivores (dogs, cats) or ungulates (pigs, goats), and massive releases of captive-reproduced game stocks (galliforms, waterfowl) is raising fear that introgressive hybridization with wild populations might disrupt local adaptations, leading to population decline and loss of biodiversity. The Widespread occurrence of free-ranging domestic or feral carnivores (dogs, cats) or ungulates (pigs, goats), and massive releases of captive-reproduced game stocks (galliforms, waterfowl) is raising fear That introgressive hybridization with wild Populations Might disrupt local Adaptations, leading to Population decline and loss of biodiversity. Detecting introgression through hybridization is problematic if the parental populations cannot be sampled (unlike in classical stable hybrid zones), or if hybridization is sporadic. Detecting introgression through hybridization is problematic if the parent can not be sampled Populations (Unlike in classical stable hybrid zones), or if hybridization is sporadic. However, the use of hypervariable DNA markers (microsatellites) and new statistical methods (Bayesian models), have dramatically improved the assessment of cryptic population structure, admixture analyses and individual assignment testing.

In this paper, I summarize results of projects aimed to identify occurrence and extent of introgressive hybridization in European populations of wolves (Canis lupus), wildcats (Felis silvestris), rock partridges and red-legged partridges (Alectoris graeca and Alectoris rufa), using genetic methods.

Results indicate that introgressive hybridization can be locally pervasive, and that conservation plans should be implemented to preserve the integrity of the gene pools of wild populations.

This means that the Mallard can wipe out other species of ducks by invading their gene pools!

This certainly calls for an expert on Genetics and Hybridization.

it's good idea to document them,i put the link in my favorites to see later ,but forom whath i see in the link, it´s a spreaded problem,because some of this birds can mate whith normal varietys and transform gradualy the original genetics of the species,that kind of cases ocurred allready in several places in the world

Here is a link which states that Mallards are prolific and undiscriminating ducks.

Beats me!!t may seem quite boring to see duck after duck. But I thought that it might be a good idea to document these.
We need some duck expert to comment on why so many hybrids.

Emma,your zone as an incredble quantity of mallard variants,i dont see that here,do you have any idea whath can cause that?
