When winter turns to spring

February 2012 will be remembered as one of the coldest on record in Catalunya. Waterfalls and rivers froze solid, and thin layers of ice even covered the ponds in Barcelona’s parks. The bitter Siberian air finally abated, and the sun felt warm again. One of the Montjuic castle sparrows was airing his feathers and singing non-stop in celebration.

A prize piece of territory on the Cami del Mar is the corner where people sit and look at the view, and quite often eat at the same time.  The robin that rules there looks sleek and smooth, no longer a ball of fluffy insulation.

Across the road from the Funicular station, there’s a tall row of shrubs, with glossy, laurel-like leaves.  Rustling and squabbling sounds emanate, as blackcaps have taken up residence there.  They are coming to the end of a copious supply of berries.

On the Cingles de Berti, small tokens of spring are visible: the first grape hyacinths and liverwort.  A common toad surprised on the path tries to ward off attack by inflating itself and standing on tiptoe, before deciding to bury itself in the leaf mulch.  Then, spotted in the distance, a long strand of birds crosses the sky, forming an immense curve: a hundred cranes powering their way north.

 

Birds on Migration in Barcelona

The three Honey buzzards soaring over Montjuic Castle run into a swarm of Alpine swifts, and start circling to gain height.  When they are specks they continue southwards. They are the most notable of the raptors who take the Catalan coastal route.

Montjuic overflows with birds during autumn migration.  Swallows are swooping low over freshly cut grass. The robin population has multiplied.  One feisty individual is jostling other birds out of a stand of trees. The woods and parks become incredibly crowded with them: too many robins in the broth, so inevitably some have to keep moving further south or inland.

Another redbreast is in evidence, the Common redstart, far from common in Barcelona, and only glimpsed on spring and autumn passage. Unlike its not particularly close relative, the Black redstart, who arrives to spend the winter, its destination is tropical Africa.

Flycatchers – spotted and pied – make protracted stopovers in the city’s parks, breaking up the long haul south. The warm weather ensures plenty of insects so they can fatten up for the tough journey ahead: the sea followed by a desert that’s expanding year by year. Slim, sprightly birds, you notice them as they repeatedly launch themselves to scoop up prey and return to the same perch.

In the woods, firecrests are back, travelling with the tit flocks, always in the lowest branches, and last to move on. There was lots to eat in this holm oak infested with gall midge larvae.

Unusual bird sightings: migration

It’s the time of year for unusual sightings in unexpected places. Recent observations recorded on Ornitho.cat include 28 Booted Eagles heading northwest and 2 Ospreys southwest, seen by an observer on a roof in the middle of Barcelona. In Sallent a goshawk was seen eating a mallard and a Black Stork was wheeling over Tordera.  And someone snapped this Griffon vulture on a structure over a busy road near Montserrat.  

Peregrine falcon chicks on Montjuic get ringed

The two agentes rurales had the difficult job of abseiling down Montjuic’s inaccessible cliff face and retrieving the three Falcon chicks from their nest, while one of the adult Peregrines repeatedly dived towards them, calling in alarm. The fiddly work was then in the hands of Eduard Durany, general overseer of Barcelona’s Peregrine population, with help from Josep García, an expert on herons among other things.

First out of the bag was a male, identified by its smaller size.  At just over three weeks old, it was still covered in sparse white down.

Peregrine Falcon chicks stolen from Sagrada Familia

Shortly after being born, this year’s brood of Peregrine falcon chicks were stolen from their nest in one of the Sagrada Familia towers.  The robbery took place out of range of the web cam installed. Visitors have no access to this tower, but there are always plenty of workers milling around, since the Sagrada Familia is still under construction. Eduard Durany, responsible for monitoring Barcelona’s Peregrine falcons, emphasises the need for better security.  Last year suspicious individuals were spotted trying to take food up to the falcons, who fetch a high price on the black market. After the theft, two chicks born in a wildlife recuperation centre were placed in the nest, but sadly the intended foster parents rejected them.  See also the report on the ringing of Montjuic’s young falcons.

A walk on the edge: spring

On the outskirts of Aiguafreda, the Cingles de Bertí loom up rather dauntingly, but the climb isn’t as bad as it looks, especially if you begin early in the day.  At the side of the track was a Dappled White, keeping perfectly still.  Its green underwing markings are like the mottled pattern of lichen on a rock.

There’s a short cut near the top cutting through dark damp woods where shadows are purple with liverwort.  Then abruptly you emerge, like a prisoner out of an escape tunnel, and look wonderingly over the top of the precipice at the flat table land.

Spring comes at full tilt with a range of sounds not heard since the previous year.  A cuckoo starts up from the valley below.  I can hear a flock of bee eaters somewhere over the fields.  A nightingale sings, still rather tentatively, from deep inside the evergreen oaks.  Then a Tawny owl starts hooting in the bright morning,  disconcertingly, like a clock striking thirteen.

Zooming in on Montjuic (iv): early insects

It was the first really warm day in February and quantities of Hummingbird Hawkmoths (Macroglossum stellatarum) were restlessly hovering in front of the castle wall, as if searching for something. They engage in this mysterious activity every year when they reappear at the end of winter. I spotted one sitting quietly, something apparently rare, but who knows how many others there were, flattened on the wall, blending in with beige-grey wings and just a hint of iridescence.

When a Hummingbird Hawkmoth feeds, it slings in its lengthy proboscis from a distance.  Not so the Carpenter Bee (Xylocopa violacea), who hugs the flower close. These gentle giants were also out in numbers, bumping into each other around the Common Borage. Their wings are brown like old film negatives, until the light catches them and they turn blue. The males signal their sex with orange antennae tips.

Judging by the constant rustle of Chiffchaffs in the small evergreen oaks by the castle, there were plenty of small bugs to feast on.  They were being deftly picked off the leaves or snapped up mid-flight as the restless birds forayed out of the trees to retrieve them.

Natur-al-Andalus has an interesting post on Chiffchaffs, whose hovering skills allow them to exploit the nectar of extensions of introduced South African aloe that bloom in the mild Gibraltan winters.

Three winter birds in Barcelona

These three insectivores find winter feeding opportunities in Barcelona’s sheltered urban environment on the Mediterranean coast.  They also share an ability to go about their business undisturbed by human proximity.

White wagtails are a common sight on the pavements and in the parks, careering after their prey.  One theory for the constant tail wagging is that it gives an impression of alertness to potential predators.  This Wagtail, zigzagging along the paths in Pedralbes Park, wears a winter plumage, with white throat and chin, and a faint yellow tinge to the face.  In summer they look much more pied.

By the end of the winter the Black redstarts who’ve moved into town become quite approachable, though finding corners where they can stay aloof from the bustle and noise.  In comparison with the Wagtails, they’re often to be seen static on a vantage point, sharply scanning the vicinity for food.  A beautiful male was sitting on one of the fig trees of Montjuic, smoky grey plumage fluffed out on a crisp cold day.

This Chiffchaff was one of several who had gathered around the park pond, snatching insects while hovering over the water or scooping them off the surrounding wall.  Small and inconspicuous, one regularly comes to the balcony to pick off the tiny bugs that always seem to infest my plants.

Unusual sightings on Montjuic

First thing in the morning, when it was still dark at street level, you could see the gulls overhead burnished with gold by the rising sun.  When I reached the Cami del Mar they were pristine white, soaring in an intensely blue sky.

The sun had cast a blinding sheen on the sea, where cargo ships threatened to combust.  The fierce light probed deep inside the crevices of the castle wall, revealing toasting Moorish geckos and Praying Mantis oothecas.  A Painted Lady opened its brand new wings, glinting with copper dust, oblivious to the biting wind on the other side of the castle.  Only a light breeze ruffled its silky fur.

More Black redstarts have been arriving: some were drinking from the leaking pipe, others perched on the Agave masts.  These vanished, to be replaced by something stockier, with long yellow legs.  I’ve never seen a Sparrowhawk on Montjuic before, the terrain of cliff-nesting Peregrine falcons and Kestrels.  Accompanied by attentive magpies, the small raptor changed perch, and then took off, a soaring silhouette over the yellow cranes in the port.

Further along, an even more unusual sighting.  A bird flew up to the castle in an unfamiliar series of shallow swoops.  Tawny stipples on the breast, a yellow base to the bill and wings edged with white spots – it was an Alpine Accentor down at sea level.  The last time I saw one was in the Pyrenees at about 2,000 metres.

Montjuic is a tempting stopover for birds on migration, a small green island on their coastal route, full of feeding opportunities. The records on www.ornitho.cat this autumn show redwing, siskins, Meadow pipits, Song thrushes, Cirl buntings, Common redstarts, Tree pipits, Subalpine warblers, a hawfinch, skylark and the tail feather of a nightjar.

Autumn colours in Collserola

Though its woods are mainly evergreen, Collserola is livid with colour in the autumn. Blue-violet Rosemary flowers hum densely with bees, and yellow Mediterranean gorse shines against the rich blue sky of San Martín. As if decorated for Christmas, the Strawberry trees are hung with glowing red and orange fruit and clusters of bell-shaped flowers, creamy white like candles.

I found a Praying Mantis in almost exactly the same spot as last year, lightly clinging to a Narrow-leaved Cistus.  It had a contented post-meal air, probably having dined on the bees in the Rosemary bush next door. After cleaning them, it neatly folded its spiky “arms” and remained motionless.

Under the dense Holm oak canopy, in the dark, boar-raked mulch, knots of scarlet tentacles emerge:  Latticed Stinkhorns (Clathrus ruber), or in Catalan Guita de Bruixa – “Witch’s Vomit”. A fungal wonder, it attracts flies with its rotten stench to act as spore-dispersers.

From a fallen tree comes the sound of Pekin Robins – or Red-Billed Leiothrix – who are hiding among the dried branches and leaves. This escapee cagebird, native to the jungles of Southern Asia, feels at home in Collserola, with its overgrown gullies and impenetrable tangles of creepers and brambles.

When disturbed they can’t seem to control their curiosity. One by one, Pekin Robins begin emerging from the dead tree to get a closer look at the intruder, all the time scolding vigorously. I got a noisy close-up of coral-red bills, yellow throats and bright black eyes.   With a steadily expanding population, their colonisation of other areas in Catalonia is imminent.
