The Oldest Saint


As I dropped down onto the Lasithi Plateau a Buzzard launched itself from a telegraph pole, narrowly missed my windshield and crashed into the undergrowth to my left where it had obviously spotted its unwary breakfast. That was a good omen as I was taking my little group of intrepid strollers to the heights above Agios Charalampos to look for Grifon Vultures. The saint, after whom the village is named, was reputedly 114 years old when he was martyred for his Christian preaching in the 3rd century, thus making him the oldest saint and his claim to fame was that, whilst being tortured, one of his torturers arms miraculously fell off and another had his head put on backwards. I think that I am more inclined to believe in Betty's black snake but more of that later.



As our little band negotiated the steep, narrow alleyways through the village and emerged on the hillside above the plateau we did indeed see Grifon Vultures and other high flying birds but it was the smaller passerines that really brought the day alive, particularly the flocks of Goldfinch. These birds are resident here in Crete but in the autumn they gather in flocks, their numbers swollen by birds migrating south from eastern Europe. As we exited the top of the village however, it was domestic fowl that caught the ever observant Betty's eye.


“Oh, look,” she said, looking up to where a group of birds were admonishing us from their pen on top of a house “turkeys!”

“Actually,' I said, not wishing to dampen her enthusiasm, “I think you'll find that they are guinea fowl.”

“They're too tall for guinea fowl,” Betty challenged.

“They're standing on the roof,” I pointed out.



Meanwhile, back to the chaffinch. The tall plant upon which she is perched is a Wavyleaf Mullein and the landscape was littered with them in various stages of life. Apart from providing staging posts for the goldfinches, leaf warblers, stonechats and sparrows, all of which were gaily flitting about on this fine autumn morning, I noticed that one had also attracted a tachinid fly. Not the nicest of flies; their maggots chew their way into unsuspecting caterpillars and eat them slowly from the inside, making sure to keep them alive as they do so, until they are almost ready to leave their host. At this point they feed indiscriminately, the caterpillar dies and the maggot wanders off to pupate in the ground without so much as a by-your-leave.



Caterpillars that are not devoured from within eventually become butterflies, of course, and these were dancing around at our feet, enjoying the nectar rich Sweet Scabious that grew by the side of the track. The name of the plant derives from the fact that it was used to treat scabies (an itchy rash caused by a mite infestation under the skin) in the middle ages. The Small White butterfly is a male which has only one spot on each forewing whereas the female has two. The other butterfly is the amazing Painted Lady which, although resident here, occurs in larger numbers in autumn and winter like the Goldfinches and the reason is the same: they migrate. Over six generations they make an incredible 9,000 mile round trip from Africa to the Arctic and back (see Secrets of Painted Lady migration revealed ).




Noticing a sign at the side of the road pointing the way to the Cave of Charalampos, Bert decided to go and investigate. Seeing her loving husband peering into what appeared to be a very large hole in the ground Betty thought that she had better go and join him to 'make sure he doesn't fall in' (at least, I think that she said doesn't). I trailed on behind, pausing to take a photograph of an old friend, Chorthippus bornhalmi. The 'cave' turned out to be a rather unimpressive hole in the ground. Presumably the roof had caved in since the 18th century BC when it was a seven chambered ossuary. Besides the bones, archaeologists also found clay figurines and musical rattles called sistra about which, I expect, they got very excited.


Having quickly exhausted the thrill of the cave I took to my favourite hobby; rock flipping (there used to be an annual rock flipping day but it seems to have died a death in 2009) and discovered a lovely little Green Toad.

“Amphibians and reptiles are often put together,” said Bert, getting down to take a closer look, “is that because they are closely related?”

The toad and Bert looked at each other with mutual interest whist I wracked my brains to remember who evolved when.

“Yes,” I replied, “Amphibians evolved from the early fish and have both lungs and gills. Reptiles are an offshoot of Amphibians and have only lungs. Mammals, such as ourselves, and later, Birds, are offshoots of reptiles.”

“Talking of reptiles,” interjected Betty, “I saw a huge black snake here on Crete once and I was told that it must have escaped from a private collection. What do you think?”

“How big is huge?” I asked.

“About two inches in diameter,” she indicated, joining thumb and forefinger together, “and it stretched all across the road with its head disappearing into the undergrowth on one side of the road and its tail out of sight on the other side.”

“Not one of the four Cretan snakes,” I ventured “but I know what it sounds like.”

“What?” asked Bert, carefully replacing the stone over the now disgruntled toad.

“A black plastic water pipe.”

“It wasn't a water pipe,” said Betty, indignantly, “it moved”.

“They can be quite lively,” I explained, “if they get an air lock.”

Betty was not convinced and I had to confess that, not being familiar with all the snakes in the world, an escapee remained a plausible alternative.





The Taverna Bit



Thanks to all at Spani's Taverna in Charalampos who hastily rearranged their restaurant furniture when we descended upon them en masse and they also provided an excellent menu. The barbecued chicken and roast potatoes were beautiful.

Sikia Beach – Frozen in Time

In previous weeks we've been back in time 800 years and joined the Venetians in their hill fort at Monte Forte and 2,000 years with the last of the Minoans at their place in Praesos. This week we're going back over 20 million years into the geological past to a beach that you will no longer find in any good beach guide to Crete. Lift a little patch of this massive slab of rock with your fingers (which is surprisingly easy to do) and you can rub the sand away from the underside with your thumb. It's covered with various lichens on the surface but let's go up and see what plants have colonised the edges. Plenty of Heather, as you'd expect on a sandy soil, and down among the roots some beautiful little autumn flowering Narcissi. We also have some spherical heads of Alliums. Garlic, onion, chive and shallot are all Alliums and we have about fifteen different species growing wild here on Crete. As to which these are I'd have to check with our botanist friend, Steve Lenton who is a man who really knows his onions. I never could get the hang of them: when I was a young man I disappointed my future father-in-law by confusing his onions with his gladioli but in fairness his vegetable plot did abut his flower border.

We also have plenty of stones and rocks for flipping which, as you know, can keep me amused for hours. Oh look, our first beetle of the autumn. In fact, this is quite a rare one called Pimelia minos, which is endemic to this end of the island and fairly easy to recognise as his back has the appearance of avocado pear skin. I've only come across this species twice before; on Koutsounari beach and at Bramiana resevoir. Pimelia may be a rare species but he is one of a group of 20,000 or more Darkling Beetles that can be found worldwide very often in dark places such as under stones which gives them their common name. 







Now who do we have here pollinating our heather? This is one of the Tachinids, a rather bristly bunch of flies as you can see. They have a tendency to lay their eggs in the larvae of other insects, particularly the caterpillars of butterflies and moths, but some prefer adult beetles or their larvae so it's no wonder our Pimelia friend likes to spend his time hiding under rocks. So would I.











I've found some old bricks over here. Let's rummage. You've got some little orange dots moving about on the bottom of that one. Here, take the hand lens and tell me what you see. They're sort of peachy? Nice. How many legs have they got? A very small, eight legged creature with peachy skin. May I take a look? What you have there is a Red Velvet Mite, quite pretty in their own way but rather predatory when they are adults. In their earlier life stages however they are parasitic on other insects. I've just found another Pimelia over here and look what's nestling in the crook of his front leg, a little velvety orange dot. Poor old Pimelia, he's not safe anywhere.







Well, what do you think? Quite a lot of life for a bare stone slab isn't there? But there's another strange creature that I want to introduce you to and you'll be pleased to hear that it is best observed from a small taverna in the nearby village of Sikia. You'd have thought that with so many wonderful creatures in the world there would be no need to make them up but mythology is full of them such as that lovely mermaid over there. If you are crossing the Aegean in a boat you may meet up with Alexander the Great's sister, Thessalonike, who was turned into a mermaid after her death. If she asks after her brother tell her that he's alive and doing well. This seems to pacify her. If you tell her he's been dead for centuries she gets all upset and starts churning up the waters.

The Extra Bit

The trailcam has been busy photographing Great Tits and Italian Sparrows galore during the day but this little fellow appeared overnight. He's a Black Rat, Rattus rattus. I'm not too worried about the occasional Brown rat around the garden but I'm not so keen on having the black ones about. However, as the trailcam also picked up three different cats investigating the bird table at night it is hoped that he won't stick around too long.
