Sunday at Castro Marim

For the second day running we woke this morning to find that it had rained overnight but when we eventually started our walk at Castro Marim it was starting to show signs of brightening up a little. It was still shorts and t-shirt weather but it did seem sensible to carry the waterproofs just in case.

Although we walked for about four hours we covered very little distance at all, probably less than a couple of miles. It takes a long time because there are thousands of birds to look through. It’s a walk that we do regularly and it never disappoints. Today we noted 70 species, which is about the number we would have predicted.

Among the highlights it was good to find Little Bustards again in exactly the same place we saw them last Tuesday, even though there were only six of them today. Raptors included the same Peregrine Falcon, a female based on its size, that we saw last week. We haven’t yet seen this bird fly, it has a fence post that it likes where it sits surrounded by ducks and waders. Perhaps it hunts and feeds early before we get there; perhaps it just likes watching the Flamingos!

Although we didn’t cover anything like the whole site, there seemed to be fewer waders today and only 15 species. Amongst these we include Stone Curlews, which we always enjoy seeing. A group of 25 of them were seen in flight. We have seen as many as 80 here but they are very difficult to get near and a decent photograph of one remains a dream.

Again we saw six species of gulls including several Slender-billed and as well as the usual Little, Sandwich and Caspian Terns there was a single Black Tern.

Migrants included several Northern Wheatears, a couple of Willow Warblers, a Whinchat and a Pied Flycatcher. Robins are also migrants and along with Blackcaps, Chiffchaffs and Meadow Pipits are just now starting to arrive here on the coast.

Finally, a flock of eight Common Magpies was an unusually high number here. They aren’t common along the Algarve coast but they are gradually spreading west.

Rüppell’s Griffon

The long drive west is starting to become a habit! At least today we didn’t go all the way to Cape St Vincent. Our target this morning was a vulture roost site in the Serra do Espinhaç o de Cã o. There had been reports of a possible Rüppell’s Griffon in the area for a few days but last night the identification had been confirmed and the bird was reported to have gone to roost with about 100 Eurasian Griffons. Raptor passage and in particular the movements of vultures are being monitored in connection with a major wind farm development. The survey team are using radar to track the birds and so the directions to the lookout point were quite precise. We arrived there at about 8.30am.

We were quickly able to locate about 30 Eurasian Griffons sitting in the trees and we were expecting to wait until all the birds took to the air before we could look for the Rüppell’s. Although a few Eurasians did get up for a brief fly around, remarkably we found the Rüppell’s while it was still perched in a tree. It stood out amongst the Eurasians as being a very much darker individual and we believe it is probably a second year bird. Although the reference books tell us that Rüppell’s Griffon is a non-migratory species that is a resident of sub-Saharan Africa, there have been quite a number of records in Iberia in recent years and we know that one was seen at Tarifa in Andalucí a last month.

Eventually, after an hour or so, most of the vultures got up and began soaring around the wind turbines. At this point it was easy to pick out two Egyptian Vultures by their much smaller size and distinctive shape but the light was awful and once it was airborne we didn’t see the Rü ppell’s again. The turbines are not yet operational but it was easy to see the potential here for the vultures to have some serious problems. Two of them were seen yesterday to collide with the turbine blades and there is little doubt that birds would have been killed if the blades had been rotating. There is a suggestion that in future the turbines will be switched off at raptor migration times but we have our doubts (to say the least!).

On the way back to Tavira we diverted to Lagoa dos Salgados for another look at the Spotted Crake (the Pectoral Sandpiper seems to have gone) and this time, although the light was still poor, we managed to get a photograph.

Another ’grey egret’ here looked to us to possibly be a melanistic E. garzetta rather than a hybrid E. garzetta x E. gularis like the one seen earlier in the week. We photographed it alongside a Little Egret. It looks like one of those washing powder adverts - whose mother doesn’t know about Persil?

Lagoa dos Salgados

This morning we set out early for Lagoa dos Salgados located about an hour’s drive from Tavira. We had received a message late last night from Ray Tipper that a Spotted Crake and a Pectoral Sandpiper had been found there, two species that are rare in Portugal. Ray had already seen them and that was encouragement enough for us to set an early alarm and visit what is in any case one of the best birding sites in the Algarve.

We had been disappointed only a few days ago to hear that Salgados had been drained again and it currently makes a bit of a sorry sight. The ongoing story of the battle to save Salgados, involving SPEA and the RSPB, has been detailed elsewhere but in spite of all the efforts that are supposedly being made to protect the site, seeing it today did nothing to cause us any optimism about its future.

Having said that, it has not yet completely dried out and there is quite an extensive area of wet mud that is proving attractive to Ringed Plovers and Dunlin and a few Common Snipe, Grey Plovers and Little Stints. And because the suitable habitat is limited, finding the Spotted Crake and the Pectoral Sandpiper didn’t prove too difficult. Also seen were one Purple Swamp-hen, four Caspian Terns, 17 Spoonbills, 24 Grey Herons, a Peregrine Falcon, countless Black-headed Gulls, several Northern Wheatears, a Whinchat and at least four Bluethroats.

From Salgados we headed back east, calling on the way at Vilamoura, a hive of activity ahead of a major golf tournament that starts there on 16th October. We had a walk in the Parque Ambientale, visiting both of the hides and then having a look at the lagoons at the adjacent water treatment plant. We had several sightings of Kingfishers, a Common Buzzard and a Marsh Harrier provided the raptor interest, Cetti’s Warblers were calling loudly everywhere, Willow Warblers were numerous and there was a flock of about 50 Yellow Wagtails. From one hide we had a brief up-close view of a Purple Swamp-hen, from the other just Eurasian Coots and Little Grebes. The lagoons held a few ducks (Gadwall, Common Pochard and Shoveler) and hundreds of Lesser Black-backed and Yellow-legged Gulls. Butterflies included a couple of Monarchs.

Brief stops at a couple of other sites on the way home produced Blue Rock Thrush, Green Woodpecker, Grey Wagtail, Sandwich Tern and Whimbrel.

Working the local patch

We were at Castro Marim again this morning. For the first time in a week it was quite cloudy and the temperature remained comfortable all day. We walked nowhere near as far as we usually do but probably saw just as many species.

The highlight was seeing a flock of 13 Little Bustards; they’re not uncommon here but can’t be guaranteed. Additional to the 19 wader species found in the same area last week were about 10 Northern Lapwings and a Wood Sandpiper. There were still a few Slender-billed Gulls; Mediterranean Gulls had increased to double figures and there were at least 100 Audouin’s Gulls. A few Northern Pintail had arrived to swell the duck numbers and in addition to the usual Caspian and Little Terns, about a dozen Black Terns were feeding over the marsh. One or two Marsh Harriers were around, a Peregrine Falcon was sitting on a post in the middle of the salinas and just as we were leaving a Booted Eagle passed over.

On the way back we checked our best local sites for Blue Rock Thrush and Bluethroat and were successful at both, although we had to be patient. It was a case of “come on out - we know you’re in there” as we sat in the car waiting for them to appear. The Bluethroat was our first of the autumn but was in exactly the same spot that we see them every year which, not surprisingly, we call ’Bluethroat corner’.

While we were looking for a Bluethroat we saw another grey egret. We weren’t able to say with any certainty whether it was the same bird we saw at Santa Luzia last week but the suspicion is that there are at least two birds that frequent the Tavira area. Ray Tipper is comparing the many photographs of these birds and we will be adding the one below to his collection. Also seen here was one of the pinkest Slender-billed Gulls we have seen. Not only were its underparts pink but also its rump, tail and primaries. Oystercatcher and Bar-tailed Godwit brought the wader species total to 24 since we arrived back here last week.

Sagres Pelagic Trip

We took a ride out to the west again this morning, to Sagres. We covered much of the same territory that we visited on Wednesday and some of the birds seen today, including the Golden Plovers at Vale de Santo, were probably the same individuals we saw during our earlier visit. There were fewer passerines today but still the odd Common Redstart and Pied Flycatcher here and there. Several Common Kestrels, a Peregrine Falcon and a Marsh Harrier were all seen before we even reached the raptor watch point.

At the watch point, where we stayed for only half an hour or so, we saw a Black Stork, three Short-toed Eagles, seven Booted Eagles and a Sparrowhawk. We heard later that 40 Griffon Vultures and an Egyptian Vulture were seen there in the afternoon but we had other plans and we have accepted now that we can only be in one place at a time!

After a coffee break at the birder-friendly Pastelaria Marreiros in Sagres we headed down to the harbour to meet Ricardo of Mar Ilimitado with whom we had arranged for an afternoon boat trip. After last month’s 11-hour pelagic trip that took us 50 miles out into the Pacific Ocean from the Oregon coast, today we were at the other end of the spectrum with a two-hour trip that took us just eight miles out from Sagres. However, we saw plenty of birds: at least one Great Shearwater, one or two Sooty Shearwaters, several Balearic and Cory’s Shearwaters, two European Storm Petrels, two Great Skuas, countless Northern Gannets and of course lots of Yellow-legged and Lesser Black-backed Gulls. Not a bad return for such a short trip and all of the birds were seen really well. And neither of us was seasick!

Audouin's Gulls

There seems to have been a clear-out of migrants overnight. There are still one or two Willow Warblers in the olive trees outside but there was no sign of a Pied Flycatcher or Redstart when we went out this morning. It's amazing to think that they have headed off across the sea and the Sahara to spend the winter in West Africa.

This afternoon we checked out a few sites around Tavira starting with the saltpans to the west of town towards Santa Luzia and then working our way back to Fort do Rota. A ‘Grey Egret’ wasn’t seen well but was almost certainly the presumed hybrid Little Egret x Western Reef Egret that regularly spends the low-tide period feeding in the same channel at Santa Luzia. A Collared Pratincole and five Slender-billed Gulls flew over as we settled down to try and photograph some of the many Black-tailed Godwits, but it wasn’t long before all the birds were disturbed by some passing children and we decided to move on.

In the saltpans by the market in town there were more Black-tailed Godwits, plus Curlew Sandpipers, Dunlins, Little Stints and Common Redshanks and plenty of Lesser Black-backed and Yellow-legged Gulls but we were looking at them against bright sunlight so again we quickly moved on.

Taking the road to Quatras Aguas we stopped to look at the gulls that were roosting around the saltpans and were surprised to find so many Audouin’s Gulls. Some of them were bunched so close together that they were difficult to count but there must have been 150 or so. With a rapidly increasing breeding population in Spain and now a few pairs also nesting in Portugal, Audouin’s Gulls are regular here but today’s count was our best in Tavira. It is said that 90% of the European population breeds at just ten sites, which is why the species is still classified as ’near-threatened’. Four Caspian Terns, several Little Terns and a Sandwich Tern were with them.

At Fort do Rota a Whimbrel called but there was little else to see other than the many Northern Gannets passing just off-shore.

Day trip to Sagres

On Wednesday, along with Ray Tipper, we made the trip west to the Sagres/Cape St Vincent area hoping to see some of the migrants reported earlier in the week and, as always, to find a few birds that we could photograph.

We began in a small area of coniferous woodland where we were pleased to find that there were still numerous Pied Flycatchers and Willow Warblers. Some of the Willow Warblers looked exhausted and it seemed likely that they might be new arrivals. At least one Blackcap and small numbers of Spotted Flycatchers, Common Whitethroats, Garden Warblers and Common Redstarts were also present.

From the raptor watch point we saw half a dozen or more Common Kestrels, a couple of Sparrowhawks, a single Marsh Harrier and a Black Stork but it didn’t seem like a day when there was going to be much movement of raptors so we didn’t stay long. A juvenile Woodchat Shrike in this area was the only one seen during the day.

As we headed for nearby Vale Santo, we stopped briefly to try and photograph a low-flying Short-toed Eagle but without much success. There were just six Golden Plovers where on another day there might have been Dotterel but there were no complaints as we soon saw Choughs, Northern Wheatears, Whinchats, Spotless Starlings, Yellow Wagtails, White Wagtails, Skylarks and Thekla Larks. Three or four Short-toed Larks flew over and we found several Ortolan Buntings. A Peregrine Falcon was the cause of temporary alarm and a Black Kite became the sixth raptor species of the day.

As the usual the area by the lighthouse was well populated with tourists so a few minutes here was long enough for us see a few Northern Gannets heading south and the usual Black Redstarts on the cliff top. We looked for a Blue Rock Thrush but didn’t find one until later when we stopped at a regular spot for them on the way back towards to Sagres. We also saw Shags here.
We completed the day’s birding with a short diversion to Martinhal where amongst a small group of Dunlins, Little Stints and Ringed Plovers we found the ‘oddity of the day’ a leucistic Ringed Plover.
