Northern Spain Trip Report - Day 5

Day 5 - Thursday 17th April 2014

Our last day in Spain dawned, along with the daunting prospect of a mammoth 300km journey back from Zaragoza to Barcelona ready to catch our evening flight back to the UK. Arriving back at the car, we spotted a flock of swifts screaming and performing their acrobatic flight high above our heads, but they were just too far up to positively nail down to a species. 

Having cleaned up on all our key target species, but still lacking any Bustard sightings, we headed towards a site near the Laguna de Gallocanta to see if we could strike it lucky with these impressive birds. A Griffon Vulture perched on one of the telegraph poles on route gave absolutely amazing views, allowing a close approach and a great photo opportunity.
Griffon Vulture - Northern Spain
Upon arrival and scoping the huge lake, I was thrilled when Alex found two stonking Greater Flamingos in the middle of the water, surprisingly far north and showing just how far up Spain this species can occur. I wasn’t expecting to have flamingos on my trip list at all, so this was a great final lifer to add on the very last day.
Laguna de Gallocanta - Northern Spain
The many terns flitting around proved just too distant to ID, as did the majority of birds on the lake, although several Black-winged Stilts could be picked out feeding in the shallows. A local informed us that we had just missed a Black Stork that had circled round and dropped by on the lake briefly – another of our wanted species – but a search around the area unfortunately provided no further sightings of this majestic and huge winged bird.

There was no sign of the bustards either, and a check in Alex’s site guide told us this was only a wintering site for the two species – the birds would be back on their breeding grounds now and would have more than likely left the area. A small gathering of European Swallowtails, the same species we get back in Britain, was a nice consolation (I’m yet to see the ones in Norfolk) and we watched around 5 or 6 of these large butterflies busy drinking from the muddy puddles on the track.
Swallowtail Butterfly - Northern Spain
A Rock Sparrow on one of the stone huts provided great views for several minutes, especially after our earlier more fleeting glimpses of this species, and an incident in one of the fields involved a true “leg it!” moment which resulted in Alex driving us off at high speed from a seemingly disgruntled local!

Leg it!
It was soon time to head back to Barcelona however, although despite the long drive (including a 30 toll charge that we had no idea about!), no more species were added to our final trip tally. A stop off at a service station provided some likely Roller habitat in the middle of the Spanish Countryside, but to no avail.

With our three main species tracked down – Wallcreeper, Dupont’s Lark and Lammergeier – the trip had been a resounding success for all 3 of us, with tonnes of laughter and memories made along the way, complete with a bucket load of new birds. 
Massive thanks to Chris who planned the entire trip and was effectively mine and Alex’s guide for the week, his quick off the mark ID skills were second to none and we simply couldn’t have done it without him. Alex also did a sterling job doing the majority of driving throughout the trip - the car certainly had an eventful time as can be seen by the state of it at the end of it's journey, absolutely covered in layers of mud and sand!
The incredible Pyrenean landscapes that engulf northern Spain are simply fantastic, and one of the most beautiful areas I have visited – rich in bird life and highly recommended to everyone. The breath-taking mountain landscapes with the roaring crystal clear rivers gouging out the mountainsides, complete with the fresh alpine air just can’t be beaten in terms of beauty, although the incredible mix of snowy mountaintops, warm open plains, dry grassland and winding forest trails were all simply stunning in their own right – a truly magical place indeed.

Northern Spain Trip Report - Day 2

Day 2 - Monday 14th April 2014

After a stop in Zaragoza where we had unfortunately timed our arrival with a traditional Spanish Easter festival involving lengthy processions through the streets by black cloaked hooded figures banging large and very loud drums (that made parking or getting anywhere in the streets a nightmare – especially as the road to our hotel was closed!) we had an early 5am start ready to be back on site by dawn.
Spain
Setting up our scopes overlooking a favourable patch of ground near the car park, we listened in the cool, calm, dawn air for the larks to rise and start singing. Several Frenchmen joined us with our vigil, and before long the distinctive flutey song of the Dupont’s cut through the morning air to greet us, a beautiful chorus unlike anything I’ve heard before. With Dupont’s Larks choosing to spend a lot of time on the ground and concealed in bushes, they are renowned for being exceptionally hard to spot, and we spent a good while trying to locate one particular singing individual that sounded quite close by but proved impossible to spot. Therefore, we couldn’t quite believe it when one of the Frenchmen casually exclaimed “I have eet” as calmly as if he was merely ordering a beer at the bar, the Dupont’s Lark proudly centred in his optics. In complete contrast and in panic mode, we hurriedly peered through his scope to admire this fascinating lark, hardly containing our excitement that we had managed to track it down (this was Chris’s fourth visit to Spain in search of this species!).

Interestingly, the lark was much further away than the sound would have led us to believe and we had been checking the bushes far to close – a good tip to locate them seems to be to always look behind where you think the sound is coming from.

This tactic did us well throughout the rest of the morning,  and a walk round the footpath revealed more snatches of song and an incredible 8 or so individuals in just a small patch, singing beautifully and showing considerably well in front of us, the distinctive long curved beak clear to see. 
Duponts Lark - Spain

The site was incredibly rich in small birds, with an abundance of Calandra, Lesser Short-toed Lark, Crested and Thekla Lark all present in huge numbers. Differing from the Crested Lark only slightly and being quite tricky to separate unless close views are obtained, Theklas have a shorter bill, with more contrasting patterns on the wing and head. The crests on Crested Larks are also slightly more pointed and raised than those of the Theklas, and it was these features that allowed us to separate the two.

Hearing the distinctive cry of a flock of Sandgrouse in the distance, we decided to drive further down the road in search of them. We soon picked up two stunning Black-eared Wheaters in flight in one of the earth-clodden fields which later perched on the dry stone wall, allowing us to watch them at length. 
Black-eared Wheatear - Spain

A walk through the area revealed 3 Pin-tailed Sandgrouse feeding in an adjacent field, providing fantastic views through the scope that revealed their stunning plumage, the beautiful metallic olive-green feathers glinting in the sun. We could see several flocks flying distantly in front of the incredible mountain backdrop, their calls echoing across the muddy plains and across the valley. Exploring the area, I turned to see two birds fly close in, and excitedly noted that their black bellies could only mean one thing – Black-bellied Sandgrouse! We watched the male and female pair quietly feeding and creeping around the hill in front of us for some time, before a low flying raptor spooked them and they completely disappeared amongst the foliage – sadly proving impossible to relocate.
Northern Spain
Ecstatic with the mornings finds, we headed to a nearby site at Belchite to explore some bombed ruins in the search for any avian inhabitants. A Black Redstart immediately greeted us from under the pines in the car park before perching on one of the broken walls, whilst I caught sight of a Rock Sparrow flitting about one of the tumbling down towers. We soon spotted a magnificent jet coloured male Black Wheatear, the sooty plumage standing out a mile away in contrast to the orange toned brick. A cracking male Blue Rock Thrush also danced around the top of one of the crumbling turrets – a really striking bird and one that I was pleased to catch up with – only one of two from the trip.

Heading back to the car park, we spotted a gorgeous Scarce Swallowtail butterfly flitting amongst the vegetation, and a quick hop down to its level saw it pose brilliantly for photos – one of the few species we could positively identify on the trip!

We were soon back on the road and heading north to our stopover destination of the brilliant Casa Boletas in the high Pyrenean town of Loporzano, spotting several new raptors for the trip in the form of an impressive Black Kite, our first Booted Eagle and a majestic Golden Eagle that was circling at the side of the road. With eagles and large raptors being high up on my list to see on the trip, I was thrilled to watch them gliding effortlessly along the thermals – having only ever seen a distant Golden Eagle at Haweswater in Cumbria before now.

Deciding to head towards a large freshwater lake that was on route, we were rewarded with incredibly close views of a Booted Eagle feeding on a rabbit right next to the side of the road before it took its prize in to the nearby trees. An exploration around the thicket of scrub surrounding the clear water’s edge revealed a colony of Mirror Orchids, my only orchid of the trip and part of the Ophrys genus – related to the Bee and Spider Orchids we get back in the UK. We soon picked out a Western Bonelli’s Warbler in the trees, as well as a beautiful male Cirl Bunting – far more common in these Mediterranean climes than in Britain, although a Western Orphean Warbler, despite its large size, managed to elude us – we could only hear its distinctive call through the branches. Another Rock Sparrow made a brief appearance, and a second flock of Bee-eaters called overhead, just about visible through the trees.

The shimmering blue lake itself surprisingly held very few birds, so we continued on to our destination, heading up extremely steep mountain roads that became increasingly and alarmingly narrow in some of the villages – expert manoeuvring provided by Alex as he heroically navigated the streets of one small town in particular that seemed built for bikes judging by the width of the alleyways! Congratulating ourselves that the car was still in one piece, I soon realised that Chris had sent us to entirely the wrong village – our hotel was situated some half an hour away in a completely different town! This meant we had to undergo the whole ordeal again, this time going downhill, and Chris was subsequently banned from any navigational duties.

Northern Spain Trip Report - Day 1

Day 1 -  Sunday 13th April 2014

After getting the evening flight from Manchester to Barcelona, a late drive to our hostel (which proved terrifying with a left hand drive and no satnav!) left no time for birding, the lone call of a Black-winged Stilt at the hire car centre the only hint of the avian delights awaiting us in Spain.
Flight from Manchester to Barcelona
Departing from the hotel in the early hours of Sunday morning, our ears soon picked up the loud screeching of Monk Parakeets in the area. A quick stop in the small park directly opposite to where we had left the car overnight revealed a handful of individuals, enjoying the peace and quiet before Barcelona truly woke up, playfully grasping large chunks of bread that a kind local had left out.

Our long drive to our stopover point of Zaragoza began, and the next bird to hit our lists came in the form of two fine Purple Herons flying directly over the car, long necks outstretched, doubtlessly heading for the large lakes in the nearby parkland. White Storks were plentiful, and having never seen them before I was left awestruck by their sheer size and majesty, soaring effortlessly on the breeze.

White Stork - Spain

Nearing Lleida, a small track off road gave a perfect opportunity to seek out more bird life. A Fan-tailed Warbler sprung up, its chirruping song serenading us, while a flock of Spotless Starlings perched in a nearby conifer, chattering away. A drive a little further along the track revealed the Spanish race (sharpei) of the Green Woodpecker, slightly differently marked than our own UK birds, while Red-legged Partridges scuttled along in the grass. A Crested Lark gave excellent views, perched on a stone wall next to the track, crest erect, singing its heart out.
Crested Lark - Spain
Heading back to the main road, our journey seemed to be on course – that was until there was a loud bang, followed by severe rattling which brought the hire car to a stop. It seemed Alex couldn’t handle roundabouts on the opposite side of the road, and had taken out BOTH right hand tyres in an argument with the curb. Despite his protestations, there was NO brick in the road that had caused the damage, purely his driving skills…… 
Flat tyre....
Alex's massacre on the tyres....
An eventful few minutes followed, with hysterical laughter from myself, accidental phone calls from Chris all the way back to a very confused owner of the Manchester airport car park, more hysterical laughter, and a struggled translation to the Spanish hire car company trying to explain what had happened. Miraculously, they agreed to send a replacement over free of charge (I don’t know what Chris had promised them in order to achieve this…) although it did come at the price of a lengthy wait by the side of a busy road surrounded by nothing but an empty garage and abandoned warehouses – at first glance seemingly barren of bird life.

However, this was not to be the case. A pair of White Stork had set up a nest on a nearby lamppost across the road, and a small group of finches flitting amongst the trees in the warehouse courtyard revealed two Serin amongst them, their yellow rumps flashing in the sunlight. A walk further down the track surrounded by a small reedbed and bamboo patch looked promising, but sadly revealed nothing.

However, a sharp eared Chris soon picked up the distinctive call of Penduline Tits in the area. A walk along the main road to achieve a better angled view of the reedbed revealed a pair had set up territory there. The curious duo left the thicket of reeds and approached us, at one point feeding in the small tree directly next to us. These stunning views followed for at least ten minutes, the pair seemingly oblivious and unconcerned to our presence. A walk to the river in search of Red-rumped Swallow proved fruitless, although another Serin gave much better views, posing in the tree for us to admire.

A quick exchange of cars later and we were back on the road. The habitat and landscapes on route to Zaragoza were stunning, with huge rivers carving through the hills and plains. A stop by the side of the road near suitable habitat revealed another Purple Heron staking out the reeds, while Great White and Little Egrets flew across the millpond calm water. The scratchy chatter of a Sardinian Warbler caught our ears, and five minutes of frustratingly brief views of this dark warbler flitting from shrub to shrub eventually gave way to a fine male singing exposed on the top of one of the bushes. This was again my first view of this species, and the red eye, complete with dark plumage was very striking, with the song particularly distinctive.
Northern Spain
A large bird of prey gliding over the hills looked suspiciously eagle-like, but the views were far too brief to nail an ID. Several Crag Martins swooped along the cliff face, a consolation for the unfortunate timing of the Flamborough bird’s arrival coinciding with our flight out of the UK! We grilled all the hirindines feeding over the river and a Red-rumped Swallow was quickly picked out, its pale rump distinctive compared to the dark rumps of the Barn Swallows. This insight proved handy, and hopefully I’ll be able to pick out this migrant on our UK shores in the near future.

Another brief stop further along the Rio Segre also produced another new bird in the form of a Short-toed Treecreeper. Similar to our native birds, Short-toed Treecreepers are the only species that reside in this area of Spain, so there was no doubt in separating an otherwise difficult pair of species.
Northern Spain
The Spanish sun was beating down at this point and our stupidly unprotected skin was starting to suffer, forcing us to resort to shelter and a well eared rest at the nearby town of Mequinenza. Polishing off ice creams, a Spotless Starling gave excellent views on a nearby aerial, allowing us to fully appreciate its much glossier plumage and brighter legs. A Hoopoe also made a brief appearance, a quick flash before flitting out of sight around the corner.
Spotless Starling - Spain
One of my main targets for this trip was to see a Bee-eater, and if I’m honest this was one of my key points in travelling to Spain. Having dipped a Shropshire bird last year, I was keen to see these brightly coloured beauties, having been on my birding wish list since I was a small child. So, it was with great excitement when Alex spotted a small group flitting around a little way down the road - we immediately headed further down in an attempt to get closer and parked up before walking a short way down the gravel slope to where the birds were flocking and calling. Dancing through the air and with their magical calls echoing throughout the sky, we counted over 30 birds swirling around our heads, taking it in turns to perch on the wires in front of us.

With several Bee-eaters perched directly opposite, they provided absolutely amazing views and I really couldn’t have asked for more, it was fantastic to see the gorgeous electric blues and sunshine yellows of these amazing creatures – truly an iconic bird of the Mediterranean and an experience I’ll never forget!

Managing to tear ourselves away from these winged wonders, we continued on with our journey, heading west on the long drive towards Zaragoza. Some dubious navigating saw us heading the long way round via Caspe that was disappointingly lacking in birds, although a Southern Grey Shrike provided a point of interest on route, perched in one of the many spiky shrubs at the side of the road and our only one of the trip.
Southern Grey Shrike - Spain
The sun-baked earthy fields on the approach to Zaragoza seemed the perfect habitat for Sandgrouse and Bustards, but countless searching from the car drew an unfortunate blank, with just a strange fox-like mammal seen hurtling across the road behind us. Calandra Larks, another new species for me, swooped and displayed in many of the fields, this large lark distinctive in its flight and great to watch as we kept an eye out for any Sandgrouse.
Calandra Lark - Spain

Continuing along the dusty tracks and passing through increasingly remote and abandoned villages on route to our next target site – the Dupont’s Lark location near Zaragoza - we enjoyed brief views of a female Montagu’s Harrier banking over the slopes whilst a Hoopoe flitted around several paces in front of the car for a good portion of the journey.

With VERY vague directions (understatement…) we drove around the dusty dirt tracks for at least an hour before Chris had to bite the bullet and make an expensive phone call back home to get clarification on exactly where we needed to be. Eventually on the right track, we travelled up the dust road before reaching the car park, taking in the beautiful Spanish plains scenery glowing red and gold in the now evening sunlight – a stunning backdrop and truly extraordinary environment.
Northern Spain
With the light beginning to fade, we simply listened, our ears taking in the amazing sounds of what could be described as the “dusk chorus”, a collaboration of the beautiful songs from the many larks in the area, all the while on high alert ready to pick out the sound of the Dupont’s interspersed within. Sure enough, we picked up snatches of the distinctive song – quite easy to hear and tantalisingly within our grasp. We were so close! Sadly, the light quickly faded to beyond the reaches of the human eye and the skies turned dark - we would have to make a return journey the next morning in search of our elusive quarry.
