Montpellier snake

A montpellier snake in Doñana

This photo of a young Montpellier Snake ( Malpolon monspessulanus Culebra bastarda) was sent to me by Dutch photographer Gerard Beersma to identify. It was about 80cm and was taken in Doñana. Once again thanks to the expert Cyberlizard, Reptiles and amphibians of Europe, and his mates Chris + Roger, the latter of whom wrote:

This is a Malpolon monspessulanus and is just like the one that fell out of a tree ( in Spain ) that my wife and I were sitting under having our dinner. I did not believe my wife when she first said a snake has just fallen onto the table and slithered off and had gone under a pile of nearby stones. It was not until I dismantled the pile of stones that I found it. It was very similarly marked to the one in the photo.

The Montpellier Snake is the largest snake in Iberia (up to 2m) and probably the commonest snake in the Mediterranean region and in Spain. This is despite the numerous deaths on the roads to which it is attracted in search of heat, and its persecution by man - it is seen as a threat to small game species and farm birds because of it size. On the contrary the Montpellier appears to be on the rise, as it easily adapts to humanised environs, which push out its competitor snake species. It is present throughout Spain , with the exception of the Atlantic strip of Northern Galicia , Asturias , Cantabria and the Basque Country. The snake is a generalist, feeding particularly on lizards* but also small mammals, birds and even small rabbits.

*In parts of Castilla it is known as culebra-contra-lagarto - Gerard Beersma tells me in Dutch it is known as a 'hagedis-slang', which means 'lizard-snake - and notes ' I remember I found once a dead one, on the road in the Spanish Pyrenees , in Aigues Tortes de Lago de San Mauricio. While I wondered if this animal had eaten something I opened it with a sharp knife, and I found a complete lizard in it. '

It is in theory one of the five venomous snakes in Spain , though the back position of its venom fangs means poison injection is unusual. Lifted from Cyberlizard's site (www.nafcon.dircon.co.uk):

This snake is one of the back-fanged colubrids which have a certain venomous capability: not usually enough to kill a human, but certainly enough to dispatch its prey (lizards, snakes or small rodents) and bad enough to inflict a good deal of pain on a person. Owing to its prey preferences it inhabits dry stony areas heavily populated by lizards, such as piles of stones on the edges of fields or near ruined buildings. When hunting it will occasionally rear up and look around, making it somewhat resemble the cobra. If it feels threatened it hisses loudly and attacks with the mouth closed. Unusually for a snake, this colubrid possesses good vision.

Aggressive and good-sighted it might be, but its frequency means that it is a common prey for a number of Iberia 's birds and mammals: a number of birds of prey particularly the short-toed eagle ( Circaetus gallicus) for which the Montpelier represents an important part of its diet), magpie, mongoose, fox and wild boar.

A Montpellier snake in La Manga

There was some debate as to this Montpellier snake taken in La Manga

I was sent these photos of what is probably (see below, there is some debate) a Montpellier snake by one Jill, who wrote:

This snake has just wormed it's way inside the front wheel of our van! It is about a metre long fully stretched - and when it stretches out and goes for it, it can go as fast as we can run! It is no thicker than my finger. It has round eyes. It rears up and hisses. Is it dangerous? Could it hurt / kill an eight-year-old / the dog?

The Montpellier snake was in La Manga, that ten mile long strip of sand which divides the inland sea of the Mar Menor from the Mediterranean in Murcia . It's arid with low scrub vegetation. Jill again: " The snake was on some wasteland (of which there is hardly any left here). There are grasshoppers, very small lizards, and crested larks and not much else on the wasteland. "

The erudite Cyberlizard, Reptiles and amphibians of Europe, and his mates Chris + Roger, noted in a series of mails:

Not sure about the wriggling Jill mentions - most colubrid snakes, I think, "glide".  I wonder if the ground was very hot or there was some other irritation?  Wriggling like a worm would normally be associated (to my mind anyway) with snakes that don't have the flat ventral surfaces, usually sea-or freshwater species.  

Roger was emphatic that it was a young or subadult Malpolon as he has kept Coluber hippocreppis and he thought the shape of the head on the photos did not match.  I must admit I was not sure as I did not think the eye looked right for Malpolon, but maybe the "scowl" is something that develops later.

If it is Malpolon, it is unlikely to be dangerous to a human, although obviously a bite should be avoided.  If it's Coluber hippocreppis, well, they're apparently a bit crazy (according to Roger) but harmless, ie probably just "act up" a bit and then shoot off into the undergrowth.

Finally Juan R. Fernández Cardenete from the Plan Andaluz de Aves Acuáticas wrote to me, confirming that:

"the colubrid in question is a subadult of Malpolon monspessulanus, with a contrasted librea that is not habitual in this species".

Note: Jill informed me that the snake disappeared from the wheel. She said it must have sneaked out the back while they were watching the front.
