Hybrids

[arthur]

oodles are cross breeds not hybrids. .

Wouldn't that only be until a kennel club, somewhere, recognized them a breed?????

Look at the Australian terrier crossed with the Yorkshire terrier, ie Silky Terrier, crossbreed or Hybrid??????

So it is different in birds?

Also, I feel towards the cross breeding of poodles, as people felt with, canary x gouldian, question...... it should not happen! Though, I do bite my lip on that one! Just trying to get better understanding, as to terminology in birds.

Like a split, means, bred to different colored bird?

Generally there aren't breeds recognised in birds (unless you look at the pigeons, chickens etc where human selection has been occurring for centuries), split is a term used to describe heterozygote or carrier birds of a particular genetic mutation, so a bird that carries the pied gene but doesn't express it is a pied split. Mutations don't change the species of a bird and don't make a new breed they are just a difference in one aspect, how people feel about mutations and their proliferation varies, In the wild most mutations would die out for one reason or another. As breeders we are able to proliferate the mutations but the question is should we keep pure lines of normal birds as well (I don't want to get into the debate here lol).
Poodles, rottweilers etc are all dogs but they are selected over a huge number of generations to look different from each other (so lots of different mutations that build up over time) breeds are a human phenonamon (sp).

Domestic dogs (Canis lupus familiaris) are a subspecies of the Grey wolf (Canis lupus). All domestic dogs are Canis lupus familiaris but the various breeds have different traits or gene mutations to give them particular characteristics. Something like a silky terrier would be more like crossing two budgey mutations or two different types of canaries.

So the hybrid is simular to, canary x siskin breeding?

Have somewhat of an understanding of canine gentics, though, I left it alone after "Genetics of the Dog," by Malcolm Willis. Just trying to transpose to birds.

My understanding of some of the terminology used in animal / bird keeping,

Breed...... A man made stabilised mutation of a single species (or multiple species,) eg. Single species, All domestic dogs, (Dalmatian, Pointer etc). chickens ( White Leghorn, Australorp etc), cats (Persian, Siamese etc), pigeons (Fantail, Tumbler etc) Canary ( Norwich, Yorkshire etc).
The only finch that I would consider a "Breed" using more than one species (debatable) would be the Bengalese (Society Finch) Going by this definition, though not in common use, all the different "Mutations" of Zebra Finches should be called breeds.

Species.... (Both singular and plural, there is no such thing as a "Specie".) A naturally occurring group of animals/plants/birds looking all pretty much the same and capable of breeding true to type. This can also be sub-classified into sub-species, local forms etc. My guess is that the three head colours in Gouldians would be classified as forms. There are no "Breeds" in the natural world.

Hybrid....( not Hybreed! there is no such thing ) A natural or human manipulated cross between two or more naturally occurring "Species" Sometimes fertile, sometimes a mule, usually depending on how far back their common ancestor was before they diverged into separate species.

Mule.... A non fertile hybrid.

Canarty X Siskin would be a hybrid until several generations later when the genetics have somewhat stabilised then it would be considered a "Breed " of canary (Red Factor)

It is interesting! This is an interesting topic viewtopic.php?f=90&t=8136" onclick="window.open(this.href);return false;
