How curious, found another European officially registered “roan” Thoroughbred also so registered here. The name of this juvenile is ZAMBESO (FR) (roan c 2011) by Zambezi Sun out of Oubliette, by El Prado. He arrived 5th in the Prix Prestige behind:

1st. APACHE SPIRIT (#9)
2nd IMPERIATOR (#5)
3rd. HONEYMOON COCKTAIL (#2 ---a grey colt)
4th MILOW (#1)
5th ZAMBESO (#6 ---partial angle)

See photo and finishing order (fifth, partially visible) at:

But he looks like a normal “grey” to me.

According to Weatherbys (bold black and underlined):
http://www.weatherbys.co.uk/sites/defau ... ooklet.pdf
these are their definitions:


“Grey: The body coat is a mixture of black and white hairs, with the skin black. With increasing age the coat grows lighter in colour. As there are many variations according to age and season, all of them should be described by the general term ‘grey’. The majority of grey
horses are not grey as young foals. All foals should be described with their predominant coat colour, but any white hairs should be noted
in the narrative.”


“Roan: The basic body colour is a mixture of many white and brown or chesnut hairs and the intensity of this is subject to seasonal variation.
The description ‘roan’ is now acceptable to Thoroughbred Authorities,
but Thoroughbreds are rarely roan. Most of those, which appear to be so,
are in the transition period of going grey.”


In addition to the pair of aforementioned basic definitions they also included the following sentence in parenthesis with these definitions:

“(This section lists the additional colours not commonly occurring in Thoroughbreds)”

“Blue Roan. Where the body colour is black or black-brown, with an admixture of many white hairs, which gives a blue tinge to the coat.
On the head and the limbs from the knees and hocks down, the black hairs usually predominate; white markings on limbs may be
encountered.”



“Bay or Red Roan. Where the body colour is bay or bay-brown with an admixture of many white hairs which gives a reddish tinge to the coat.
On the head the bay hairs usually predominate. On the limbs from the knees and hocks down, black hairs usually predominate: white
markings may be encountered.”



“Strawberry or Chesnut Roan. Where the body colour is chesnut with an admixture of many white hairs. On the head and limbs from the knees and hocks down, chesnut hairs usually predominate; white markings may be encountered.”


I suppose that all the aforementioned definitions have nothing to do
with the Catch A Bird phenotypical roans.

A new officially-registered European so-called "roan" case has appeared.

His name is:
BUSHIDO (roan c 2011) http://www.pedigreequery.com/bushido10

It must be clarified, though, that the visual appearance sported by
this case has no tangency with the genuine phenotypical
"roans" descending from the lineage of Catch A Bird.

The genuine phenotypical "roans" (up to this day,
the ones coming from Catch A Bird) are the ones
sporting a darker-head, darker points, with sprinkled
hairs that never whitens with age (contrary to what
usually occurs with greys).

The Australian stud book does not have a category for roans. Pheno type roans of the catch a bird pedigree are registered as their underlying base color ie bay; chestnut etc. catch a bird did produce a number of true roan types, but due to them being registered as base colored horses they were never highlighted. An example is wild dove by catch a bird who was also a pheno type roan. She is still not recognized as being a roan. These progeny are producing phenotypical roans in their offspring as well. We now have four generations of them. They too are registered as bay or chestnut even though they are true roans.

Fluer,

Thank you so much for your very valuable and
informational participation on this topic.

You are bringing up great information for all of
us who avidly want to study more on this theme.

Many of us would really love to read more on the
fascinating roan lineage and even on the non-roan
lineage of Catch A Bird.

Can you please inform us more at the following thread?:
