The weather continues fair

Suffice to say I’ve been a busy bee since my last post. My continued quest to identify roller pairs and nest sites has paid dividends though, as I now know of approximately 40 pairs breeding within my study area! However, rollers are sneaky creatures, being very wary around the nest site, which has meant that I’ve still only managed to locate the exact nest location of maybe half of these. Luckily most of the birds have now got chicks to feed, with the majority of eggs hatching over the past ten days or so. Once the adult birds are feeding young it does make nest location a hell of a lot easier, although it also unfortunately means that for many pairs we won’t have data on laying dates or hatching success. Never mind, there’s always next year…


Not pair number 50 unfortunately

Anyone for an omelette?

Dinosaurs!

Rollers are primarily
insectivorous...

We did have some drama at one of my nests though, located in the incredibly picturesque Theletra Gorge area. About two weeks ago I found a roller egg below the nest site which had obviously been predated. Nevertheless, mum and dad continued to valiantly tend their remaining clutch until the middle of last week when their behaviour changed suddenly.  During one of my daily checks I noted both birds repeatedly swoop at the nest hole and alarm call, but refuse to enter the chamber. Unsurprisingly, on my visit next day the nest entrance was dripping with egg contents and blood and I found two eggs containing near-to-hatching chicks smashed on the ground below. All in all very distressing, but this is the nature of field biology.

Aside from the nest checks I’ve mainly been carrying out vegetation and invertebrate sampling, which has been interesting and painful in equal measure, but most especially tick-filled! A few of my sweep net and pitfall samples have also produced some interesting catches for a closet entomologist like myself with a camel spider, scorpion, and mantis all collected from various sites.
My daily rounds have also continued to produce sightings of a range of interesting wildlife, a few photos of which are provided below. The second week in May was particularly noteworthy as the island was overrun by a deluge of migrating bee-eaters. Double figure flocks were encountered calling overhead or feeding from wires at practically every site I visited, which made for a colourful few days. Sadly this episode pretty much marked the end of avian migration on the island, with the resident birds now getting down to the business of breeding.

Having not had a day off in over three weeks I decided to free up a few hours yesterday morning and go for a short hike in the Avgas Gorge, which is located within spitting distance of Kritou Terra. Walking through the gorge is an amazing experience, with sheer cliffs looming overhead and only a handspan apart in places. Their walls are covered with a range of interesting plants, including the incredibly rare and range-restricted Akamas knapweed. This species’ global distribution is located entirely within the Avgas Gorge system and it is subject to one of the smallest ‘micro-nature reserves’ that I’ve ever come across! However, my main reason for walking the gorge was to look for one of the island’s charismatic dragonfly species; the magnificent emperor. This is Europe’s largest species of dragonfly and its European distribution is restricted to Cyprus and a few Greek islands. I was lucky enough to see at least four of the huge, blue, pink and black-ringed males patrolling the gorge’s central river, with one of them guarding a yellow and black female as she laid her eggs at the base of a riverside boulder!  All in all a good few hours off…

But I was soon back to work, as tomorrow I’m joined from the UK by Chris Hewson from the British Trust for Ornithology. Together we’ll be attempting to catch the adult rollers and attach geolocators and colour rings to them in the hope of tracking their migrations between Cyprus and sub-Saharan Africa this autumn and next spring.  Wish us luck!

All go

So, I’ve now been in Cyprus for five weeks and things are moving forward nicely (even if not in the manner I’d originally planned). I’ve spent much of the past few weeks trying to locate breeding roller pairs and then mapping the broad habitats surrounding their nest sites. As you can probably imagine, this is a somewhat lengthy process (especially in the absence of any previously produced field maps) but I’m just about getting there. The habitat types out here are surprisingly diverse and it’s meant that I’ve had to curtail my somewhat grandiose planned invertebrate and vegetation sampling regime in order to leave enough time to actually watch the birds!

The rollers are all nicely settled now and it looks like one or two pairs may already be laying. Many of the pairs in the study area though are still only examining nest holes so there’s probably going to be a fair spread date-wise when it comes to chicks appearing. It’ll be interesting to see if the birds become anymore territorial once the females are on eggs, as they’re already incredibly rowdy. I watched one pair this week having an aerial dogfight with a pair of hobby and another pounding on a somewhat innocuous pair of little owls that share their territory.

Chez Phil is getting more and more crowded with equipment, thanks to the arrival of 10 RFID readers and various large plywood offcuts, and the fridge is half full of dead insects. Luckily my landlady has a cosy little annexe in place in case I completely run out of room. Although my sole confidante on a day-to-day basis (the eponymous Brenda) may have other ideas, as she rules the courtyard.

Driving around my somewhat extensive study area does mean that I’m getting to see a fair bit of Paphos District and much of the really cool wildlife it supports. I’ve rescued two different chameleons from the road in the past week and the fields are full of very pretty butterfly-like Aschalaphids.  Another rather nice surprise last weekend was the sight of three (green?) turtles sculling around close offshore on a millpond sea. One thing that isn’t so nice to see is the number of dead snakes on the road. From what I’ve read, there’s a real hatred of snakes in Cypriot culture and I’m sure many of the animals are purposely run over as they bask on the road surface. Thankfully I’ve seen plenty of live ones too, so they seem to be doing okay.

As for the other birds, suffice to say that spring migration in Cyprus has to be seen to be believed. Below are a few photos of some of the more interesting sightings I’ve had lately. The red-footed falcons were part of a single flock of eighty birds(!) and there are actually fourteen pratincoles in that photo somewhere… Bee-eaters are a constant presence and the cheerful song of the black-headed bunting is now resounding around my upland study sites after their long journey back from the Indian Subcontinent.

And so it begins

As you’ve probably gathered by now, I’ve not been particularly hot on updating the blog of late… However, as I’m now in Cyprus carrying out my first season of field work (and with lots of pretty things to photograph) I’ll do my best to keep you updated over the next few months.

Suffice to say that the lead up to my departure from the UK on the 5th April was a little bit hectic, with most of my time spent running around like a headless chicken trying to organise kit and logistics for both me and my fantastic MSc student Alli (who’s now out in Portugal collecting data from our other study population). Unfortunately a lot of our equipment wasn’t quite ready in time, or hadn’t arrived in the post, prior to my departure but you can see from the photo below that I wasn’t short of a doo-hicky or two.

Having arrived in Cyprus, I thought it only fair to spend a couple of days acclimatising and exploring the island. This did ultimately also lead to me doing a fair bit of birding… A few of the more interesting feathered bits and bobs are pictured below.

The landscape and wildlife out here in general are wonderful. There’re wildflowers all over the hillsides, including Cyprus’s famously diverse bee orchid species and more tongue orchids than you can shake a stick at.

I’m now very much settled in my new home in the village of Kritou Terra. I share the courtyard with the Cypriot family next door, a plague of cats, and a particularly curious dog called Brenda. More importantly, I’ve got at least three pairs of rollers breeding within earshot of my front door (I can hear a pair of them chattering away as I type).

Finally, a roller!

A new nest site


Thanks to the previous census work carried out in the vicinity of the village by Derek Pomeroy and Frank Walsh I’ve been fortunate enough to locate several historical nest sites locally. After spending a few days driving around the study area I’ve managed to locate at least fifteen pairs; only another five to go to make the ideal study population size! Watch this space...
