Rhodes - May 2013

Over 20 years ago I visited the Greek Island of Rhodes with my wife for a holiday, this year we decided to go back. We were thinking of staying in England, but with the weather being what it has been of late....we needed some sun. My birding activity was generally limited to walks around the resort of Kolymbia, where we stayed, but we did hire a car for a few days and were able to explore farther afield, something we did not do on our last time. The sites I visited were based on information gathered from the Fatbirder website, the link to it is here.

On reading that information it was apparent that April was the best month to visit the island, but that wasn't an option, so our trip was scheduled for mid May. My trips to eastern Turkey in May have been excellent and birds have still been on the move, so I was optimistic of seeing some migrants, whilst still mindful that this wasn't a birding trip. Rather than produce a day by day diary I have grouped my sightings under site headings as has been done on the Fatbirder site.

Appolakkia Reservoir
The incentive for visiting this site was that it was cited as the only deep and permanent freshwater that can be found on the island. Although according to the map we bought, the reservoir north of Ghadhoura Dam would also appear to be permanent freshwater, and larger, but we did not make it to this site. I have to admit that we arrived at the dam around lunchtime, so not the best time for birding, and that may explain the lack of birds recorded. On and around the reservoir we recorded little egrets, grey heron and little grebe, with long-legged buzzard, hobby, golden oriole, northern wheatear, eastern olivaceous and sardinian warbler and jay either overhead or in the nearby scrub. We didn't stay for more than an hour so with more time and at the right time of day the area could be more productive I am sure.

Kolymbia
Most of my birding was done on the headland to the north of the resort. To be honest there wasn't too much to see bird wise, other than the resident hooded crows, crested larks, Sardinian warblers, greenfinch's, linnets and goldfinch's. But on occasions there was a small passage of migrants with European bee-eaters recorded and occasional red-footed falcons passing through.

Other species recorded included white wagtail, black-eared wheatear, common kestrel, raven, a squacco heron, which looked well out of place on a headland, and a flock of 10 little egrets. Hirundines were well represented with barn and red-rumped swallow, house and crag martin and common swift all recorded.

Common Raven Corvus corax recorded on two occasions on the headland

With the bird life being fairly limited my attention was drawn to other species groups. The most notable moth species was what I presumed to be white-collar burnet, at least 20 were recorded daily feeding on nectar. This is not a species I had seen before and I note that there are several similar species, but white-collar seemed to be the most similar.

White-collar Burnet Zygaena carniolica

There were plenty of reptiles to catch up with too, it is always fun trying to get a good shot. Starred agamas were numerous, not just on the headland near Kolymbia but at all the sites we visited around the island. This species is one that I have regularly encountered in Turkey where they vary greatly in colour...that was the case here on Rhodes too.

Starred Agama Laudakio stellio

A species that was new to me was Lacerta oertzeni. I assumed that this individual was a Balkan wall lizard when I found it, but on checking with a reptile enthusiast mate, I was informed it was most likely L. oertzeni.

Larcerta (Antolalarcerta) oertzeni

Apparently this species is not strictly a wall lizard (Podarcis) but belongs to the rock lizards, although in the Eastern Aegean it fulfils much the same ecological niche as wall lizards. A cracking beast whatever role it fulfils I think.

Larcerta (Antolalarcerta) oertzeni

Another species that was very common around the resort was Turkish gecko. Every time we got back to our room after dark, this species was all over the walls. They were surprisingly translucent and are easily identified since the adhesive pads do not extend to the tip of the toe.

Turkish Gecko Hemidactylus turcicus


Kremasti
I was drawn to this site because there were previous report of a white-tailed plover and Baillon's crake here, admittedly that was a few years before and in April, but you never know. The site is located just north of the airport and before you arrive at the centre of the town. On arriving I immediately picked out a little stint in the middle of the river.

Little Stint Calidris minuta

Several species of heron were also present, squacco was the most numerous, with seven recorded.


Squacco Heron Ardeola ralloides

They were generally very confiding but occasionally birds would take flight, showing the contrasting white wing feathers. Grey and purple herons were also present and reed, Cetti's and eastern olivaceous sang from the scrub and reeds.

Heading down stream I came across a cracking black-crowned night heron roosting in a nearby tree, but no sign of any crakes or plovers.

Black-crowned Night Heron Nycticorax nycticorax

On the way back to our accommodation we stopped at an amazing species rich meadow. European bee-eaters, hoopoe, European turtle dove and woodchat shrike were present. But the highlight for me was a stunning cricket. It was predominantly dark in colouration, but with white and red patterning and a green ovipositor.


Poecilimon hamatus

After a bit of research I was able to pin it down to Poecilimon hamatus. Apparently this species occurs in Turkey and on the Island of Rhodes only. It is quite different to other Orthoptera in that the female responds to the male acoustically. For more information check out the following link http://naturewonders.piwigo.com/picture?/1191

Poecilimon hamatus

I did manage to get a few pictures of some other Orthoptera but have not yet had the time to sort them out, so they will have to wait for another post.


Plimmyri and Southern Tip
The southern tip of the island was quite spectacular. It was much lusher than the northern half of the island, with more dense scrub and less development. Our first stop was Plimmyri; on arrival there did not seem to be much to see, but after a bit of effort I saw a couple of squacco herons, a great reed warbler, woodchat shrike, spotted flycatcher a very confiding eastern olivaceous warbler.

Eastern Olivaceous (Isabelline) Warbler Iduna opaca
Black-headed buntings were relatively common and a male and female red-footed falcon hunted over the nearby fields. The usual Sardinian warblers and crested larks were as abundant as ever. Moving on we headed on to the southern tip of the island, the scenery was great and the crashing waves were very popular with wind surfers. The only new bird species of note was a cracking male black-headed wagtail.

After lunch we headed north up the western coast stopping at various view points on the way. At one stop I wandered off into the dunes and immediately stumbled across the remains of a dead turtle.

Remains of a Turtle Species - Both Loggerhead Caretta caretta and Green Chelonia mydas turtles
breed in the Mediterranean, unfortunately it was not possible to identify the remains of this one

Apparently, there are two species of turtle that breed in the Mediterranean, loggerhead and green. The loggerhead has been the subject on many studies in the Ionian Sea and its breeding success studied. One of the highest causes of mortality is fishing, but these remains were too old to look for any cause of death. The shell was at the highest point of the tide line, and could have just been washed in or the tide, or maybe this beach in the site of a small breeding colony and the turtle had rolled over whilst coming ashore.

Snake-eyed Lizard Ophisops elegans

Another new species for me was snake-eyed lizard, so called because it has an unusual eye adaptation. Looking closely it is possible to see the unusually large and shiny appearance of the orbit.

River Ghadhouras
I think that any of the river valleys are worth a look if you are travelling around, unfortunately I only had time to look at one. The River Ghadhouras is down stream of the aforementioned dam, and partly because of recent storms, and being fairly early in the year, there was still plenty of water and mud present.


Black-winged Stilt Himantopus himantopus

I hadn't brought any sturdy footwear with me and parts of the river bed were quite muddy, nonetheless I was able to navigate my way through. Eastern olivaceous warblers were common, as were crested larks. Red-rumped swallows foraged overhead and a couple of stone curlew gave tantalising glimpses, but called frequently. Two wader species were present, three black-winged stilts and a sanderling, but despite extensive searching there were no other species. This area has previously supported little-ringed and ringed plover, wood, green and marsh sandpiper and collared pratincole...but not today.

Sanderling Calidris alba

A broad scarlet or scarlet darter was the only species of dragonfly to settle long enough for me to photograph it.

Broad Scarlet Crocothemis erythraea

A couple of European bee-eaters hunted from some overhead wires, one of them caught a large grasshopper (most likely an Egyptian grasshopper) and preceded to throw it in the air to break of all the legs before swallowing it....presumably just in case a sting was present.

So despite this not been a birding trip, I was able to catch up with a few regular European bird species and some excellent reptiles and invertebrates. I have not had the time to add up the species tally but that was not really the point of the trip.

The Göksu Delta, Southern Turkey - May 2011(Part 1)

The trip began with a flight from London's Heathrow Airport to Adana in Southern Turkey, via Istanbul, and after a couple of hours driving we arrived at the Lades Hotel, Tasucu which was to be our stop for three nights. This trip was going slightly earlier than many previous trips to the area, (30th April to 9th May), but that added an element of surprise to our trip which made it quite exciting. The first full days birding began with a visit to the Goksu Delta, and a chance to explore the lakes and surrounding wetland and farmland. The Goksu Delta consists of a large flat area where the Goksu river enters the Mediterranean Sea, and includes two lakes, Akgol and Paradeniz, and a huge sand spit which extends into the sea.


The southern watchtower, overlooking Akgol lake, was our first stop, and this gave us the chance to scan the lake and surrounding reeds in search of Purple (grey-headed) Swamphen and Marbled Duck, which are two of the local specialities. I did not see these species,  but enjoyed scanning over the reeds in search of different raptor species in amongst  the common Western Marsh Harriers.

The heat haze combined with the size of the lake made viewing difficult at times, and having to scan through hundreds of Common Coot in search of a Swamphen did not inspire me. However the mixed flock of White-winged, Black and Little Terns soon boosted the enthusiasm, and as I continued to scan a Great Bittern got up from the reeds and flew north whilst two White Pelicans soared overhead. Garganey, Ruddy Shelduck, Purple and Grey Herons were all recorded, and a flock of Alpine Swifts filled the skies above.

The nearby reeds and scrub were fairly dense and viewing was again difficult but we did end up with good views of a pair of Blackcaps, several Graceful Prinias, White-spectacled Bulbuls and a couple of Spur-thighed Tortoise.

After the southern watchtower, we continued through the dunes and pools in search of migrants. Apparently the lake was holding more water than usual and therefore most of the waders were on the pools, but unfortunately for us we had arrived on a Sunday, along with  most of the residents of the nearby village, so many of the birds had gone. Wading birds were still present in good numbers though with Little Stints being the most numerous. Little Ringed Plover, Spotted Redshank, Greenshank, Wood Sandpiper and Ruff were all recorded, but the most vocal and striking wader species were the Spur-winged Plovers.

Spur-winged Plover - T. D. Codlin

These birds were extremely photogenic, although they were constantly taking flight to 'see-off' the Marsh Harriers as they flew overhead. The Spur-winged Plover is considered to be a scarce breeder in South-eastern Europe, but in the Goksu Delta it was relatively common.


Spur-winged Plover T. D. Codlin

Of the passerine birds recorded in the Goksu Delta by far the most striking was the Yellow Wagtail, which in this part of Europe is represented by the subspecies Motacilla flava feldegg or Black-headed Wagtail. I have seen this subspecies many times before, but have never noticed the subtle white stripe between the black hood and the yellow on the cheek, at first I thought it might be a trick of the light but it was present on all the male birds I saw.


Black-headed Wagtail T.D.Codlin

For lunch we stopped near a narrow channel which links Lake Akgol with Lake Paradeniz; a sand bar extends in a southerly direction from this point, this provided an ideal roosting location for a few Yellow-legged Gulls, Sandwich, Common, a couple of Caspian Terns and a lone Grey Plover. A handful of Greater Flamingos fed in the lake behind. A chance meeting with a Belgian Birder tipped us off to the presence of a Cyprus Pied Wheatear in the area, and it was not long before we found the bird. Good views confirmed the identity of the bird, but it disappeared before I could get any photos.

Squacco Herons T.D.Codlin

Continuing east the farmland was an excellent area to explore, White Stork and Squacco Herons fed along the damp areas and Crested Larks were abundant along the tracks. Black Francolins were calling from the nearby fields, presumably from a suitably prominent perch, but despite our best efforts we were unable to find one.

White Stork T.D.Codlin

Our second days birding (2nd May) began with a visit to the north of Akgol Lake and the northern watchtower. Overnight rain had brought about a fall and migrants were everywhere. Whinchats, Red-backed Shrikes, Spotted Flycatchers, Lesser Whitethroats, Black-headed Buntings and European Bee-eaters were all recorded but the highlight was a flock of around 20 Red-footed Falcons.


Black-headed Bunting T.D.Codlin

The male birds were stunning and showed off their silvery primaries as they hovered over the fields, whereas the females showed off their pale rufous underparts. Six Short-toed Eagles, a 'Steppe' Buzzard, two Common kestrel and a Hobby were also present, adding to the spectacle.

Female Red-footed Falcon T.D.Codlin

As we continued along the track we encountered several Eastern Olivaceous Warblers, Common and Great Reed Warblers and a Plain Tiger Butterfly. A singing Moustached Warbler was present in the reeds by the northern watchtower. I have seen this species on Majorca before and therefore was slightly surprised to the see how pale the underparts were, and then noted that this part of Turkey is represented by the subspecies Acrocephalus melanopogon mimicus.

Moustached Warbler ssp. mimicus T.D.Codlin

We spent a while looking at this bird as it sang from a prominent perch, its distinctive song and short primary projection confirmed its identity, then it was time to move on. Finished with the Goksu Delta, we next headed inland to the village of Uzunchaburc for the afternoon, I will write about that in my next post.
