Hi Tp, Fapas have been using photo trapping for a while now. It's obviously a very hit and miss method of animal tracking but they've had great results with it. Their equipment is not as hi-tech as the system you describe though.

And I've just remembered, Fapas appear to be still looking for a certain model of Canon compact camera for their work if anyone has one.

Greetings Lisa and All,
Thanx for that link - excellent stuff which all should read (pdf and in Sp.). The following struck me (tying in with Lisa's previous posting on lordosis * ):
Quote
En el caso del lince, los autores del artículo publicado en la revista Quercus en diciembre de 2001 explican que lo más eficiente fue colocar un cebo de olor. Unos 2’5 ml de orina de una hembra, obtenidos de un ejemplar de un centro de recuperación, fueron suficientes para despertar la curiosidad de los linces y atraerlos a la trampa.
(In the case of the lynx, the authors of the paper published in Quercus explained that the most effective bait was to use a female's urine, which naturally attracted the lynxes' curiosity and drew 'em to the photo-trap.)

So I suppose in the case of JCM video they set up the cameras along the trail habitually used by lynx - as per scats found previously - dropped a few sex pheromones at strategic points (not facing sun) - tightened the trip-wire and went home in time for tea.


And to think I nearly got me 'ead chewed off by our overseas badger expert for kindly suggesting that Derek use peanuts (which he was perfectly willing to do) to bring badgers within snapshot distance in what would have been iberianatureforum's first scientific field study, way back before summer. It still rankles or smarts or whatever ... :-[

* I know I've mentioned it elsewhere, but for those of you who haven't read it, ¡Eres una Bestia, Viskovitz! by Alessandro Boffa is a must - pun intended!

For the record, in case anyone is taking Technopat seriously on this, the Junta de Castilla La Mancha's videos of the two lynx are def. hand-held and not remote-controlled!
I've been wondering exactly how one goes about taking a urine sample from a lynx. It's all very well blithely stating "take a sample" but it can't be easy, particularly from a female  :noidea: I suppose they're all territorial so a strategically placed receptacle would do the trick as they urinate in the same places as well as scent?
P.S. Is Derek still smarting/rankling?

I think they leave scent markings to attract lynxes.

Greetings All,
Wasn't too sure 'bout entering into the fray on this as it looks like leading to yet another iberianatureforum scatology-based thread, but b. that as it m., I don't suppose it has to be a particularly fresh, or even liquid, sample. Cleaning out the cages at the lynx house should be more than enough.
I base this on my (male) cat having marked 'is territory on the back seat of car in February. We are nearing end of October and even if the patch has since been cleaned, shampooed, ammoniacked on a twice-monthly basis, the moment there is the slightest bit of dampness in the air, the habitáculo (En. anyone? )is filled with fond memories ...

Lisa, if what you say is true - and I hasten to add (for the record) that I don't doubt it - then for me the whole JCM lynx thing (as it stands) is a scam. The director general of JCM in his wording (speaking here from memory) specifically leads us to believe that the images are the result of photo-trapping. I had just been harbouring that remote possibility of camera shake being due to primitive remote-controlled equipment. No longer. So back to initial scepticism.
Regs.,
Technopat

Hi all, Just managed to catch up with this topic... interesting

Here's that link you asked for earlier TP... Too much technology in Doñana!
http://www.iberianatureforum.com/index.php/topic,750.0.html

Of course the European funding for the newly discovered lince population will be huge...

'Scuse my ignorance (and poor grasp of Spanish) Tp, but do remote cameras follow and zoom in and out on an animal? The height is right for the filming to have been done humanly too. Anyway, I'll go back to the link to read it again. Whatever, if these lynx had just been released (as it looks like to me ie they're not chasing anything and they're not running away from the camera/person) and the Junta were planning on the press release to El País, wouldn't they have had/got a decent camera/camcorder to do the filming? Curiouser and curiouser.
Nick, in the article by the female biologist (can't remember her name) on the Fapas page it def. says "orina". Not that it matters really.
Clive, what can you be insinuating  ::)

Greetings All,
For those of you as yet unable to follow the Sp. on the ellinceiberico forum, here are a coupla (3) recent developments and points from yesterday/today:

1. they seem to be unfazed as to whether the photos are set up or not, basically taking it at face value that lynxes have been reintroduced or have managed to survive. Thus
Quote
La noticia no sería EL LINCE IBÉRICO VUELVE A MONTES DE TOLEDO, creo más bien que el titular debería ser LAS POBLaCIONES DE LINCE EN CASTILLA LA MANCHA VUELVEN A SER PROTEGIDAS Y ESTUDIADAS.
(Rather than "The lynx returns" (original newspaper headline) should read "Lynx in Castilla-La Mancha once again being protected and studied").

And similarly, but with a different take:

Quote
Aunque también pienso como otros foreros, que más vale que suframos creyendo que hay menos linces que los que hay que no sea una noticia de dominio público para que los lugares donde está se terminen convirtiendo en un parque temático.
(Like other forumers, I agree it's better we suffer thinking that there are fewer lynxes than in actual fact there are, rather than the news entering the public domain and the places becoming theme parks.)

2. They are also talking 'bout the importance of there being 3 neighbouring CCAA (Andalusia, Extremadura and Castilla-La Mancha) in which lynxes are protected and extensive enough for them to move freely - tho' highly critical of the several artificial barriers such as autovías, fences around private estates, etc.

3. Technopat is especially elated as one of the people on that forum (who shall be nameless) mentions the sighting of a lynx very near to where (which shall not be revealed, except that it was Castilla-La Mancha) Technopat was sure he had also seen a lynx paw print last winter. Roll on winter  :dancing:

Greetings All,
On the off-chance of me heading off to where X marks the spot before acquiring my Yuletide digital camera - with which to post pics. of scats, paw prints and what-not for you lot - methinks it might be a good idea if y'all give me a crash course in how to avoid confusing a lynx with a Felis silvestris tartessia. As the chances of seeing one in the fur, as it were, are remote, I think comparative paw prints and scats would be of more use than photos of the animal.

Optimistic regs.,
Technopat

PS.
Of course, if I actually get to get bitten by one, will do utmost to post pics of bite marks before heading off for those nasty rabies jabs, and the P-that-B will finally have to let me post on that Bites and Stings Only thread  :dancing:

In the interests of research, specifically Technopat's, I've found two very interesting pages with info on cat prints - Wildcat. Lynx and domestic.
Basically it's very hard to tell the difference, you have to look at the size and even then the tracks of a male Wildact can be easily confused with those of a female Lynx.
The first photo is from http://www.navalvillardeibor.com/LINCE.htm where they reckon the pic is of Lynx. Extremadura, not that far from the Montes de Toledo.


Next from http://www.barbastella.org/mastozoologia/gatos.htm a pic of Wildcat tracks. These are between 3,5cm - 4,5cm with Lynx being a couple of cm's bigger in length.


Ignore the pooh Tp, but I'm off to compare my photo of feline scat!

Hi Lisa,

You were right to qualify this with "they reckon the pic is of Lynx".
This isn't a lynx. Felines retract their claws and so don't normally leaves marks - (though they might in soft mud or when they jump) and also the print is rounder. This is a dog  - or wolf, and if in Extremadura, probably the former.

Have a look at these images
