Anonymous comments + Teaser

My blog has recieved almost 600 comments by now, which is awesome. I appreciate each of them and am thankful for the vivid interest in my posts!
But one thing is that a lot of commenters here write anonymous comments. That's not a problem per se, but confuses me because I don't know with how many people I am dealing with and who I wrote something already or not, with the result that I wrote the same stuff multiple times. That's a bit impractical. Therefore I would like to ask my commenters to pick a consistant name for their comments, just for me to know who I am dealing with to maintain a useful mode of communication. When posting, there is a function "Comment as" where you have a lot of options - one of them is "name/URL" where you can type just any jibberish as "name" if you prefer not to reveal your true identity. Or you could simply write your name or "name" below or above your actual text in the comment. I prefer pseudonymous over anonymous. 
But again, I appreciate each comment that I recieve and am very happy that a number of posts created a lot of fruiteful discussion. This request is just for my orient myself easier with all responses that I recieve. Thanks, folks! 

And now a little teaser: 
My next post is going to be on the European water buffalo and buffalo in Europe. I have been planning to write on that for ages, but I never got to it.

An illustration of 20 aurochs-like breeds and more


What I am going to present to you now is the work of several weeks. I am sure that a lot of my readers will know my table of a selection of aurochs-like cattle I did for Wikipedia, showing breeds used in the Tauros Project in comparison to the aurochs. However, looking at it now it is unsatisfying. Some of the drawings are anatomically imprecise and sloppy, and not always artistically convincing. Furthermore, out of laziness, some of breeds are just modified versions of the aurochs drawing at the bottom. Also, many of the drawings are “too optimistic” over proportions, body conformation or size of the respective breeds. And there is another problem since the table was originally meant to be an illustration of the Tauros breeds: Highland cattle and Tudanca are missing. So I felt I had to do a new one.



But I wanted to draw way more breeds than just the cattle used in Tauros, therefore I decided to split the images up: one table showing a selection of aurochs-like breeds in general, and one showing the breeds of Tauros. Then I had the idea to do one for the Uruz Project as well. And also my aurochs vs. Heck cattle drawing desperately needed a remake. All in all I decided to do 23 breeds plus the aurochs as a reference – both male and female, therefore 48 individuals.



I believe that one cannot make a useful distinction between “aurochs-like” and “non aurochs-like” cattle because there is a fluid continuum, therefore the level of primitiveness I chose is arbitrary. As on the original version, optics are the main criterion, otherwise I had to include feral but not that aurochs-like cattle as well. I chose to do the primitive landraces, so Heck cattle is not included, because it is a result of the first “breeding-back” attempt and therefore another story. But I did this breed as well, on the “Heck vs. aurochs” table. (I could have illustrated Taurus cattle as well, but for now this “breed” is a bunch of recent crossbreeds, many of them still half-pure, and there is a continuum to non-crossed Heck cattle, what is why I regard it as a special, advanced form of Heck cattle) This highly heterogeneous breed was a bit of a challenge, because my intention was to present average, representative individuals and there are just so many possibilities.

Actually I faced that problem in a lot of breeds. I did not want to do the “best of the best” individuals, but animals that give a balanced impression for the whole breed. However, I excluded the really ugly and derived or obviously crossed individuals from my consideration. My Limia bull has a light colour saddle, although there are Limia bulls that do not – I gave my bull a saddle not to implicate that the colour of this breed is always the same as in the aurochs. The same goes for my Lidia and Heck, although there are members of the breed with a fairly accurate aurochs colour. The same goes for horn shapes. I had to pick those traits that are prevalent, and if these are very aurochs-like but not always, I included some minor “flaws” in my drawing. Otherwise the image would be blurred.

All animals are drawn to same scale. My aurochs bull is meant to be 180cm at the shoulders, because I intended to take the Eurasian, specifically Central European, aurochs as a reference, which is usually the target of “breeding-back” projects. For some breeds, deciding for the right size was tricky, especially those which bear a lot of variation. I mainly took the Domestic Animal Diversity Information System as a reference, but also other sources and what I some breeders told me. For some breeds I was not able to find precise information, so I had to guess.



My drawings are pencil drawings that were painted with GIMP. Each individual was painted separately, but I did not do a pencil drawing for all of them: I edited the pencil drawing of the Pajuna bull and cow into Modicana, the Casta-Navarra bull is the Lidia bull with head of my Alistana-Sanabresa, both Serrena are a plumper version of the Sayaguesa, and the Tudanca cow is the Limia cow with a fitting horn shape.

Only the great table shows a human (man, about 180cm tall) for comparison, I decided not to insert a human or scale bar into the other images to not distort it.



Table of the 20 breeds:


The table shows an arbitrary selection of breeds. I could have illustrated twice or thrice as much. Texas Longhorn is not on the table because I decided so – not that some of its individuals are not as aurochs-like as Camargue or Serrana negra and so on. Serrana negra, which looks like a stockier black version of Sayaguesa, is present while Berrenda, a piebald version of Lidia, is not – arbitrary. Betizu is not included because I primarily see it as a feral breed (which are another story) that does not have a resemblance to the aurochs that is as eye-catching as in most of the other chosen breeds. Chillingham cattle is not on the list because I do not consider them aurochs-like enough, and I even do not regard them as truly feral. I did not include the ominous “Maltese ox” because there I do not have enough information on it – not even a clue on how many herds there are, I only know of one and I fear there are not many more. Some of you might wonder why I did separate illustrations for “Podolian cattle group” and Hungarian Grey. Of course the latter one is a member of the former, and there is a continuum between all the breeds of that cattle family. But I decided to do a separate drawing for Hungarian Grey because the almost completely white, bulldog-faced members of the breed are certainly rather distinct from the less derived Podolian cattle and I needed one for the Uruz table anyway. My Podolian bull and cow are a generalized type of what we find many of the less-derived Podolian strains, such as Maremmana, Italian Podolica and Boskarin.  


Breeds of the Tauros Project:




These are the main breeds of the Tauros Project. You might point out that one of their Sayaguesa cows is 25% Alistana-Sanabresa, but I do not consider that relevant – otherwise I would mention that breed as a founding breed for Taurus cattle as well. The “Podolian cattle” are representative of Podolica, Maremmana and Boskarin, and whatever they are going to work with from that group. From what I have heard they are also going to use local breeds in Eastern Europe, but so far there is nothing official that I know of.



Breeds of the Uruz Project:




Well there is not much to say. The Uruz Project also intends to do breeding projects with Maronesa, Barrosa and Lidia, but only by selection within the breed alone. My table shows the breeds that are used for crossbreeding for now.



Heck cattle compared to the aurochs:

I chose normal Heck cattle size of about 142 cm (bull) and 132 cm (cow) at the shoulders. There were about a dozen possible colours for both sexes in sum, and the level of sexual dichromatism ranges from as strong as in the aurochs to nil. My Heck bull has a light colour saddle, to show that a considerable number of Heck bulls has it (probably about the half or so) and that the sexual dichromatism weaker than in the aurochs after all. This colour saddle could have had a reddish tone, but I decided to give it a light beige tone to show that Heck cattle often have a more or less diluted colour without exaggerating it. The cow however is undiluted. It is a little bit darker than what we imagine most aurochs cows to be. All in all I think that both individuals display colour schemes that are very widespread in Heck cattle, and that I was neither too pessimistic nor too optimistic regarding sexual dimorphism. Some Heck cattle have small white spots on their belly or in rare cases are completely piebald, so I was not sure whether one of my Heck individuals should show a little spot or not. I came to the conclusion that, although it is very apparent in a number of individuals, they are not common enough in the population to be necessarily included into my illustration.

There are also a lot of possibilities of what the horns of a Heck bull or cow looks like. Either the horn shape is more or less reminiscent to that of the aurochs or not at all – either their size is as large as in the aurochs or even really large, or rather small. Often the horns are as upright as in Podolian cattle, sometimes about 90° relative to the skull and very rarely below. I chose to give my Heck cattle “usual” horns that are common in the breed: medium-sized horns, with a curvature that is basically reminiscent to that of the aurochs but too weakly pronounced, to much upwards and outwards, which the bull having horns facing slightly more forwards than in the cow. Regarding body shape, proportions, dewlap, udder and skull shape, I tried to avoid the extremes and to show what is most common in the breed.

Honestly I have to admit that I think I did a good job at illustrating “typical” Heck cattle and that my comparison with its ancient predecessor is fair.



Overall I am very contended with my new illustrations, both regarding authenticity and also artistic quality. It was a lot of work, but also a lot of fun. I hope you like them too!
