Corfu and Paxos 2013

As in 2011 and 2012 I was invited back to Corfu by the Durrell School of Corfu to lead aspects of herpetology for Gerald Durrell’s Corfu 2013. However, this year I decided to stay on the island for a little longer once the field course had finished. In the company of Swedish ex-pats Bosse and Marie Stille (Bosse being a crazy herper like me and Marie a Botanist) we decided to spend several days on the island of Paxos, just south of Corfu. Indy, a young male husky also joined us for the majority of our time in the field. Many thanks to Bo and Marie for allowing me to stay with them at their home.

In total, I spent 14 days exploring Corfu, 7 of these for the Durrell School in the company of Dr David Shimwell, Dr Lee Durrell, Colin Stevenson, David Bellamy, Rosemary Bellamy and Alex and Dave Ashcroft. This allowed me to learn many aspects of other areas of flora, fauna and culture of the island that I am less accustomed to, and in turn I could introduce them to many of my favourite reptiles and amphibians during our explorations.

Although I was able to find many species whilst conducting the guided walks on Corfu I had a number of nice finds searching in the evenings by myself or after Gerald Durrell week, when Bosse and I explored the island.

After one of the wettest winters on record the vegetation all over the island was very high indeed, often over at least a metre high. This was great for the flora and the insects but spotting and then catching reptiles, especially snakes became very difficult. At times we became frustrated chasing snakes in the tall vegetation and not being able to even see let alone catch them. This resulted in a rather small ratio of caught snakes compared to the number we saw (usually 5-10 a day). Nevertheless we found and photographed the majority of species found on Corfu. We were especially pleased with finding an Aesculapian snake (Zamenis longissimus) a rare species on Corfu which I managed to snatch from the road on the last day before it was run over. Another highlight was finding five Nose-horned vipers (Vipera ammodytes), mostly out crawling at night. We saw some species in high numbers, for example over 40 Grass snakes (Natrix natrix persa) and over 30 Balkan whip snakes (Hierophis gemonensis). Although we didn’t count, we easily saw over 50 Glass lizards (Pseudopus apodus) which were more common than any of the snakes (excluding Natrix natrix around fresh water). Unfortunately road-killed snakes were a very common sight, often over 10 per day, some days over 20. But we did manage to save a couple.

Corfu

Balkan terrapin (Mauremys rivulata) found commonly at most fresh water sites we explored.

Juvenile Glass lizard (Pseudopus apodus)

Bosse ready to pounce for a snake!

Marsh frog (Pelophylax ridibundus) could not stay off the roads at night.

Our first snake was this huge 120cm Dahl’s whip snake (Platyceps najadum) found under a large tin. A few days later we found an adult Four-lined snake (Elaphe quatuorlineata) under the same tin.

I lost count of many of these I removed from the roads around wetland areas: Grass snake (Natrix natrix persa)

This angry female Nose-horned viper (Vipera ammodytes) was the only viper that I caught during the daytime.

Greek slow worm (Anguis graeca) was found commonly during my time on Corfu.

Orchids abound at higher altitudes.

And more..

One evening I found this juvenile Nose-horned viper (Vipera ammodytes) under a stone.

I enjoyed a privileged week at the Villa Alexina

San Stephanos

My favourite walk: right next to the sea I saw a large Montpellier snake (Malpolon insignitus) climbing a tall rock, sadly I slipped as I made a grab for him and broke my 3euro sunglasses…

Nice place to stop for dinner

I found this baby Balkan whip snake (Hierophis gemonensis) under a stone. Mummy and Daddy both escaped me on the same walk.

While in Corfu town I dropped by to see a friend.

They’re everywhere…

See?

Just too late: a banded Caspian whip snake (Dolichophis caspius). Not common at all on Corfu.

Bands of same adult snake, typical of around half of adults found on Corfu.

Montpellier snake (Malpolon insignitus)

Aesculapian snake (Zamenis longissimus) rescued from the road on the final day.

This Leopard snake (Zamenis situla) was found on a road at night. It behaved oddly when picked up and died soon afterwards. Despite not having any damage it must have been hit by a car. I only found a sloughed skin of these species during the rest of the trip.

This 60cm pre-shed male Nose-horned viper (Vipera ammodytes) was the last snake we found and was found again at night.

Same specimen

Paxos

We spent 3 nights on the small island of Paxos and was forced to spend a fourth night on the island after weather conditions were not suitable for our boat ride back to Corfu. Taking only twenty five minutes to drive from corner to corner we did not expect to find many species living here. Indeed we were correct but based on a small amount of literature we had some surprise findings. Like Corfu the island has a dense covering of olive groves whereas along the coast small areas of maquis still persist. Paxos seems to have a number of differences to Corfu geologically, and is generally a more rocky island. There are no natural fresh water sources on Paxos.

We found 5 species of reptile and no amphibians on the island during our stay. Two of these would appear to be new records. Dalmation algyroides (Algyroides nigropunctatus) was found everywhere, but never in large numbers and was the only lacertid present. An old record of Green lizard (Lacerta viridis) seems highly unlikely to us, as does a record for Starred agama (Laudakia stellio). To our surprise we found a number of Kotschyi’s geckos (Mediodactylus kotschyi) under stones. This species is not found on Corfu. We also found a couple of Turkish geckos (Hemidactylus turcicus). As for the snakes, 14 Balkan whip snakes (Hierophis gemonensis), half DOR, would indicate that this is a very common snake on Paxos. Twice we even encountered individuals being killed by feral cats, which are an even bigger problem on Paxos than on Corfu. The first species we saw on the island was a 120cm Aesculapian snake (Zamenis longissimus) crossing the road. Over the next few days we realized that they grow large on Paxos. We caught a female of 175cm and found a very fresh DOR male of 185cm. A further 120cm specimen was also found as a roadkill which would indicate the species is at least quite common on the island.
