Sunday morning

After a couple of days of much cooler weather with not too much sun and more than enough rain, it was pleasant to be out this morning in bright sunshine. There was quite a strong wind at times, which meant that it was never really very warm but it was a definite improvement on Friday and Saturday and better than the forecast. Unfortunately, the rain had made the trail at Castro Marim rather muddy but this gave us a rare opportunity to wear our wellie boots, brought from the UK for just such days.

From a birding point of view it was an unremarkable morning that yielded just over 70 species, none of them unexpected, but when they include Greater Flamingo, Spoonbill, Little Bustard, Audouin’s Gull, Hoopoe, Crag Martin, Southern Grey Shrike, Azure-winged Magpie, Spanish Sparrow, Serin, Spotless Starling, Sardinian Warbler and 16 different waders it’s impossible not to be impressed.

The numbers were also impressive. On the saltpans there were hundreds of Flamingos, Northern Shovelers, Pied Avocets, Black-tailed Godwits, Lesser Black-backed and Black-headed Gulls and on the river we counted almost 400 Eurasian Coots as we searched through them looking in vain for a Red-knobbed. On the surrounding farmland, Golden Plover numbered around 150 and there were big flocks of Skylarks, Goldfinches, Linnets, House Sparrows and European Starlings.

Marsh Harriers are common here but we never tire of seeing them and they often help us by disturbing the wildfowl and waders from the far side of the marsh to which we have no access. There were two of them this morning, struggling to cope with the wind. Eurasian Teal and Northern Pintail rose from the water as they passed over but the small handful of Greylag Geese remained unconcerned.

We stayed until lunch time and then made a brief visit to Altura tank before returning to Tavira for a welcome bowl of hot soup!

A Rocha

When Dave and Sue Smallshire were here recently they gave us two publications that Dave acquired on his last visit to Portugal 17 years ago. They were the A Rocha Observatory Report for the year 1990 and An Atlas of the Wintering Birds in the Western Algarve, published in 1987, also by A Rocha. Both of these have made really interesting reading and it is clear that the status of several species, not surprisingly, has changed significantly over the last 20 years or so.

Anyway, reading these reports prompted us to head west this morning to visit Cruzinha, the base from which A Rocha has been researching and monitoring the wildlife, particularly birds, of Quinta da Rocha and the Ria da Alvor for more than 20 years. Situated midway between Lagos and Portimã o, the Ria de Alvor is one of the most significant coastal wetlands in southern Portugal. It was designated as a RAMSAR site in May 1996 and it is also one of the Natura 2000 network of sites. However, if you thought that these titles implied a degree of protection for the area you would be wrong - this is Portugal! Right from the start A Rocha has been faced with the threat of building development and that threat continues, as does the fight to safeguard the future of an area the importance of which for wildlife has been amply demonstrated. Unfortunately, in these parts the interests of wildlife are considered much less important than those of developers even when internationally recognised and designated sites are involved.

Bird ringing by A Rocha began in 1985 and since then more than 60,000 birds have been ringed. Every Thursday visitors are welcomed to the observatory to watch the ringing activity or indeed, if qualified and licenced to do so, actually help. Marcial Felgueiras had already completed the first net round when we arrived and we watched for an hour or more as the birds were ringed, weighed and measured. The catch comprised mainly of Robins, Blackcaps and Chiffchaffs but there was one surprise, a Goldcrest, only the eighth of this species caught here. Slightly concerning was the generally poor condition and low weights of the Chiffchaffs, perhaps an indication that they were recent arrivals. The Blackcaps, on the other hand, seemed to be well fed.

Later we had a walk around the nearby marsh where we found the expected wader species, plus about 20 Greater Flamingos, a couple of Spoonbills, a Bluethroat and numerous Meadow Pipits and Spanish Sparrows. One of the Spoonbills was colour-ringed (lots of them are) and we have reported the details.

Back to Castro Marim

Yesterday was a photography day as a result of which we have added new images of Azure-winged Magpie, Black Redstart, Chiffchaff, Linnet and Dartford warbler to the slideshow on our website. Of the fifteen species that came within camera range the most remarkable, however, was a Pied Flycatcher, the first we have seen since 15th October. Although it was able to fly, it did seem to have sustained some damage to its left wing so perhaps had decided against going for the trans-Saharan crossing hoping instead to survive the winter here. We’ll keep an eye open for it.

Today we were at Castro Marim (again) and as usual recorded more than 80 species. On a warm sunny morning it was difficult to be surprised by Yellow Wagtail and Barn Swallow and really there was nothing unexpected. Almost the first birds we saw were three Little Bustards, a species that we have seen on six out of our eight visits since the beginning of October but in four different, widely separated areas of the reserve so that they are never guaranteed. Other highlights were a single Slender-billed Gull (a species that we are hoping SPEA will soon accept is not a rarity!), Lesser Short-toed Lark, 12 Little Terns, 2 Caspian Terns, Peregrine Falcon, 110 Black-necked Grebes, about 40 Shelducks and at least 25 Stone Curlews.
We ate our lunch by the Guadiana River and couldn’t resist trying yet again for flight pictures of Sandwich Terns. However, none were an improvement on the earlier, more easily obtained images of birds on the saltpans.

Sandwich Terns

As usual, we stopped at Altura on the way home but nothing much there had changed since our last visit. Counting the birds on and around the tank is never easy but there looked to be about 100 Mallard, 50 Common Pochard, four Northern Shoveler, about 20 Little Grebes and ten Eurasian Coots.

Double Crested!

With an unusually high number of Yellow-browed Warblers occurring this autumn in Britain and other parts of Western Europe it was probably just a matter of time before the species was reported in Portugal. Yesterday afternoon we received word of one in the Algarve, at Barranco Velho. Apparently it was found alongside the main road by a lucky birder who was walking back to his car having stopped in the village to buy a bottle of water. Unfortunately, it has not been seen since but it has put us on notice (as if we needed it!) that treasures can be found amongst all the hundreds of Chiffchaffs.

Yellow-browed Warbler follows Dusky Warbler, Little Bunting and Wallcreeper in a list of recent rarities here in which Goldcrest has gone unmentioned. Although not as rare in Portugal as a whole as the other three, Goldcrest is definitely a scarce bird in the Algarve and several long time birders have been seeing them here for the first time during the last couple of weeks. Today we caught up with Goldcrest at Ludo where we were birding with our friend, Georg Schreier. We had seen three Firecrests before the ‘rare’ Goldcrest appeared!

Firecrest

One of the main reasons for going to Ludo was to try and photograph Penduline Tit, a mission that proved impossible. It wasn’t that we couldn’t find our bird, just that it (or possibly they) showed no signs of wanting to co-operate. Other species of note here before we went off to nearby Faro beach for a cup of coffee were Common Buzzard, Booted Eagle and Iberian Green Woodpecker.

Later we made a rare visit to the ETAR da Zona Noroeste de Faro - the water treatment works by the airport. Access is currently even more difficult than usual as building works are in progress but through the perimeter fence we were able to see that most of the ducks were Shoveler with a few Teal and Gadwall amongst them, plus a few Little Grebes and Eurasian Coots. Our reward for an otherwise unremarkable visit was a Great Egret, a scarce bird in these parts and maybe the same individual we saw in the Ludo area almost three weeks ago.

The temperature today again reached about 70º F. Amongst several butterflies seen was a Wall Brown.

Doñana National Park

Yesterday we crossed the border into Andalucía for a visit to Doñana National Park probably one of the best known birdwatching sites in Europe. It is a vast area and in a day trip it is possible to cover only a small part.

We chose to head for the José Antonio Valverde Visitor Centre and we timed our visit so that we could have our lunch there. On our way to the Visitor Centre we made numerous stops beginning at a lagoon that had thousands of ducks on it, the vast majority of which were Northern Shovelers. We spent quite a while searching for the local specialities, Marbled Duck, Red-knobbed Coot and White-headed Duck but found only the last of these. At least seven White-headed Ducks were comparatively easy to see even amongst the huge flocks. The lagoon also held maybe 100 Great Flamingos and Black-winged Stilts in numbers that were uncountable - thousands of them. Add Little Egrets, Cormorants, Eurasian Coots, Little and Black-necked Grebes and it made quite a sight, particularly when a Marsh Harrier or a Red Kite passed over and spooked a few hundred birds.

A short distance further on we found our Red-knobbed Coot at a fairly reliable sight for this species that we have seen only occasionally in Portugal. There were several of them wearing neck collars just like the one that occurred at Quinta do Lago earlier this year. Also here was the only Black-crowned Night Heron of the day.

Apart from the stilts it was surprising how few waders we saw. There was an occasional Greenshank but otherwise the most frequently seen species during the day was Green Sandpiper. As we drove along rough tracks with ditches on either side, we flushed Green Sandpipers on numerous occasions. Greenshanks and Green Sandpipers are two of our favourite species - we really are tringaphiles!

Of course there were plenty of White Storks and during the day we came across a dozen or more Black Storks. And eventually we found Cranes. Just how many Cranes there were is difficult to say but one flock that we saw in flight was estimated at about 700. They made a wonderful sight strung across the sky. Also see in skeins were hundreds of Greylag Geese.

It was quite a good day for raptors. As well as Marsh Harriers and Red Kites we saw countless Common Kestrels, a couple of Hen Harriers, a single Griffon Vulture, a Short-toed Eagle and a Merlin. The Merlin was getting amongst the flocks of larks and pipits. There were simply hundreds of Lesser Short-toed Larks.

It was particularly pleasing to find a Barn Owl. It was roosting in a derelict building that we have checked for this species on almost every occasion we have been to Doñana. Today, at last, we found someone at home!

When we eventually reached the Visitor Centre there were rather few birds there compared with the numbers we see in the breeding season but as always we enjoyed watching Purple Swamp-hen and there were several Penduline Tits in the bulrushes.

As we were leaving the National Park, one of the day’s highlights was finding ourselves almost eyeball to eyeball with a Black-shouldered Kite. It was on a roadside post, no more than four feet high, eating a prey item and we managed to pull up almost alongside it before it reluctantly flew off, taking its meal with it. It isn’t often that we can get so close to a raptor in the wild.

Doñana is well know for its spectacular sunsets and as we headed for home the sky turned a marvellous mixture of orange and red that made a fine end to a most enjoyable day.

North to the Alentejo

After days out in the west and to the east, today we travelled north to the Alentejo. The excellent weather continues - although the morning started very cold the temperature rose to around 70° F by mid afternoon.

Soon after leaving Mértola we saw our first Eurasian Griffons, about 15 of them on the ground. It was presumably much too cold at that point for them to think about flying, but later we saw several birds rising on the warm air.

Bustards were among the targets today and we soon found a group of 11 Great Bustards. It was only after we had been watching them for a while that we saw that there were also 20 or more Little Bustards just a short distance from them. When a couple of Black-bellied Sandgrouse flew by we knew we had stopped in the right place! Further on we stopped at our favourite Great Bustard view point and saw another three of these elegant birds. We also saw several more Black-bellied Sandgrouse.

As always in this area raptors were a feature of the day. Common Kestrels, Red Kites and Common Buzzards are numerous but we saw just one Hen Harrier, one Peregrine Falcon and two Black-shouldered Kites. The star bird of the day, however, was a Spanish Imperial Eagle. We saw it first soaring some way off and in fact there may have been two different birds. We could not be 100% sure of our identification as we looked against the light but we were reasonably confident. Later, at our lunch stop not only did we see one much closer but also with the light behind us and having gained some height we were actually looking at it from above. Now there was no doubt what it was!

The road between Mértola and Castro Verde is well know for the many White Stork nests on the roadside telegraph poles. There are stretches of road where there is a nest on just about every pole - or at least there were nests. For some reason during the summer the nests have been removed and when the storks return they are going to be in for a shock. Instead of a bit of gentle nest repair they will need to start nest building from scratch and with no platforms on the poles to help them the likelihood is that they will have problems. Probably they will take to the trees. It will be interesting to see what happens.

Sunday is a hunting day in Portugal and so all day we saw men wearing camouflage gear with dogs and guns. We do wonder, though, whether the disturbance they caused resulted in us seeing more birds. Certainly the bustards and sandgrouse seemed quite mobile and we saw several groups of them in flight.

On the way home we made a brief stop at Altura tank. The light had all but gone but it was clear that the numbers of Mallard, Common Pochard and Eurasian Coot had all increased since our last visit. No doubt we will be there again quite soon.

West and East

Thursday was devoted to a trip out to the west: Cape St Vincent, Vale Santo, Sagres, etc. although it was another sunny, cloudless day again there was a chilly wind.

We began at the lighthouse where we quickly found a Blue rock Thrush and several Black Redstarts. We looked hard for Alpine Accentors up to about half a dozen of which have wintered here in the past. Last year our first was on 6th November but there was no sign of them today.
Looking back towards the raptor viewpoint we could see that there were Griffon Vultures in the air so we headed in that direction and eventually saw about 350 of them. There were also a couple of Egyptian Vultures, at least two Black Kites, maybe three Booted Eagles and a Black Stork. We stayed watching them for quite a while during which time at least 10 Short-toed Eagles and 10 Common Buzzards also passed over.

As we headed for Vale Santo, we came across a Ring Ouzel and later we saw three more, one of which at least seemed to be of the race alpestris. Vale Santo had a flock of 400 or more Golden Plovers; at one point they were panicked by two large falcons. Presumably they were Peregrines but we did recall that this was exactly where we once saw a Lanner Falcon. A large area of land had been ploughed and a tractor was still going back and forth with Cattle Egrets, White Storks and White Wagtails the main beneficiaries. There were lots of Meadow Pipits, Skylarks and Thekla Larks. Other birds of note seen during the day were Northern Gannets and a Shag, Crag Martins, Ravens and Red-billed Choughs.

Yesterday we went a short way east and spent the day at Castro Marim. It was far less windy than of late and we enjoyed some excellent birding. In the total of more than 80 species recorded the highlights for us were probably Little Bustards, Lesser Short-toed Larks, Yellow Wagtails and Northern Wheatear (both rather late), Hen Harrier and about 100 Black-necked Grebes. We were also pleased to see the Peregrine Falcon on its usual post. It is difficult, though, to pick highlights out of so many birds.

After several days with little but birding, today was earmarked for catching up on some domestic stuff - shopping, washing, etc. An Egyptian Vulture was seen over Tavira during the morning. Later we did find time to have a couple of hours around the Tavira and Santa Luzia saltpans where we counted 25 Audouin’s Gulls, the Grey Egret was in its usual place and we photographed a few waders. Bird of the afternoon was a Temminck’s Stint that flew in and dropped by the roadside. It quickly walked into water that almost covered its legs but you can just see that they are yellow.
