Red-breasted Merganser in Tavira

Red-breasted Merganser is a scarce winter visitor to the Algarve and one that we have never seen around Tavira so it was a surprise to hear that one had been seen this week from the Estrada das Quatro Águas.

 Red-breasted Merganser

The bird, a female, seemed quite settled in a deepwater pan and we watched it feeding successfully for about 20 minutes during which time it didn’t seem at all bothered by our presence.  At one point it actually flew for no apparent reason and came to rest back on the water quite close to where we were standing.

For months the Estrada das Quatro Águas was subject to road improvements and other redevelopment works, most of which were completed earlier this year.  It seems odd that we have ended up with a very wide pedestrian pathway and a rather narrow road between the town and the ferry.  Parking by the roadside is now impossible and the days of driving along this road and birding from the car are well and truly over.  It really is a pity that no birdwatchers were consulted during the planning stage of this work.  We might well have done things differently!

Our visit to see the Red-breasted Merganser again highlighted the fact that in future it will be necessary to bird this area on foot.  We don’t mind walking, in fact we enjoy it, but now it will take much longer to cover the area and no longer will we be able to sit in the car and watch Bluethroats or read the rings on the Audouin’s Gulls and that's a pity!

Bad light fails to stop play!

After an enforced absence from the Algarve that lasted several long weeks, we returned to Tavira on Monday evening.  Those unproductive and frustrating weeks with very little birding or photography are the main reason why there has been no recent update here on the blog.

On Tuesday we managed a couple of hours birding around Tavira and Santa Luzia and it was good to see all the familiar species still in their regular places.  When we are here all the time it is easy to take for granted the Spoonbills, Greater Flamingos, Slender-billed, Mediterranean & Audouin’s Gulls, the Bluethroats and Caspian Terns but a few weeks away gave us a fresh appreciation of them.  We sat and watched Dunlins, Little Stints and Greenshanks and even took a few photographs!


 Greenshank

Yesterday, we spent the day in the Castro Verde area where we saw most of the species that we might have hoped for.  Great Bustards and Black-bellied Sandgrouse were easy to find but we didn’t see Little Bustards until three were flushed by a Red Kite.  That was one of perhaps thirty or more Red Kites seen during a day when raptors of one species or another were in view most of the time.

Great Bustards

We have seldom enjoyed a day with so many sightings of Black-winged Kites and after all the talk and debate in the UK about Hen Harriers it was good to have several opportunities to actually watch them.  It was also a treat to be able to watch a Golden Eagle but sadly there was no Spanish Imperial Eagle on this occasion.

It was reported here last week that a Spanish Imperial Eagle was one of the victims of a recent poisoning incident in the Castro Verde SPA.  Eight Red Kites were also found dead.  To say that this is disappointing is a massive understatement.  After being absent from Portugal for many years, Spanish Imperial Eagles have been making a comeback and they had become birds that we would expect to see on most visits to the Baixo Alentejo.  This latest one is the fourth to die there this year from poisoning.

Common Cranes

We went to the Alentejo particularly in search of Cranes and we were not disappointed.  They were difficult to count but there were more certainly than 1,000 of them.  Unfortunately, they were too far away for worthwhile photographs and the light was very poor but that was the story of the day so we’re already thinking about when we can go again!

Back in the Algarve at last!

We’ve been back in the Algarve for just a week now and seem to have timed our return quite well.  The weather is very pleasant but no longer uncomfortably hot, children have returned to school and birds are migrating!

 Short-toed Eagle

Already we have been to Castro Marim, Ludo, Quinta do Lago, Parque Ambiental de Vilamoura, Lagoa dos Salgados (twice) and Sagres (twice) and seen more than 120 species.

Castro Marim, usually one of our favourite reserves, proved to be something of a disappointment.  There are plenty of birds there, particularly in the Cerro do Bufo sector but with access to the site restricted it is difficult to get close to many of them.  Highlights were Black-necked Grebes, Audouin’s & Slender-billed Gulls and of course there are hundreds of waders and Greater Flamingos but a telescope was definitely a necessity.  The salt harvest is in progress and it looks to have been a productive season.

There was also much salt-related activity at Ludo.  As so often, it was raptors there that proved most popular with five Booted Eagles putting on a show and a single female Marsh Harrier quartering the reedbed.

At Quinta do Lago, Little Bitterns were the stars.  We saw seven or maybe eight different birds.  A Water Rail showed well; a juvenile Black-crowned Night-Heron and a Whiskered Tern were unexpected treats.  We lost count of the number of Western Swamphens but nine of them were together, completely in the open on the golf course; two Glossy Ibises took off and left before we had much chance to look at them.  Five species of gulls were on the lagoa de São Lourenço and two or three Kingfishers were chasing each other about.

Lagoa de São Lourenço from the hide

The Parque Ambiental de Vilamoura has become a favourite place at this time of the year and it didn’t disappoint – it was full of birds!  Most numerous were Willow Warblers and Chiffchaffs and Yellow Wagtails with one or two Northern Wheatears and Pied Flycatchers but we know from past experience that all sorts of rarities can and do turn up here at this time of year.  We will be back for another look very soon.  A Black-winged Kite here was reasonably approachable.

Northern Wheatear

The water level at Lagoa dos Salgados was lower than we would have liked but still there were impressive numbers of birds.  Notable were a Marsh Harrier, an Osprey, a Black-winged Kite, at least four different Bluethroats, a Little Bittern, several Western Swamphens and what appeared to be a thunbergi-type Yellow Wagtail.  Waders included Little Stint, Bar-tailed & Black-tailed Godwits, Common Snipe and Wood Sandpiper.  We searched through hundreds of gulls without finding anything other than fuscus, michahellis and ridibundus.  Glossy Ibises were especially numerous and on our first visit we estimated that there might have been as many as 1,000.  We managed to read colour-rings on several of them, which identified their origins as breeding sites near Sevilla and Huelva in Andalucia.  Two colour-ringed Spoonbills had travelled further – one from France and one from the Netherlands.

Both of our trips to Sagres produced reasonable numbers of raptors and importantly there were good, close views of many of them.  Most numerous were Black Kites (31 on the first visit, slightly fewer the second time).  Also seen were Egyptian Vultures, Short-toed Eagles, Booted Eagles, Honey-buzzards, Common Kestrels, a Sparrowhawk, a Goshawk and a Peregrine Falcon.  Two Black Storks came close overhead.  We saw just a single Little Bustard and a couple of Red-billed Choughs, while migrants included a Wryneck, several juvenile Woodchat Shrikes, Common Redstarts, both Pied & Spotted Flycatchers, Whinchats and Northern Wheatears.

So, not a bad start (for us) to the autumn migration period and still more than enough places to visit.

Birdfair 2016

We spent last weekend at the British Birdwatching Fair, generally referred to as ‘The Birdfair’ or simply ‘Birdfair’.  It’s one of the highlights of our year and we would hate to miss it.

As always, we were part of the Avian Adventures team, there to promote the company’s programme of birdwatching and wildlife holidays, some of which we expect to be leading in the months ahead.  Of course, we were also there to talk about birdwatching in the Algarve.

Birdfair is held at Rutland Water and is jointly organised by the Leicestershire & Rutland Wildlife Trust and the RSPB.  It encompasses the whole spectrum of the birdwatching industry whilst at the same time supporting global bird conservation. This is the event of the year if you’re into birds and wildlife.
One of the main attractions of the Birdfair is the opportunity it gives us to meet up with the countless friends we have made over the years through birding, many of them from overseas.

Birdfair has raised astonishing amounts of money for a wide range of conservation projects (£320,000 in 2015).  This year’s beneficiary will be the national NGO Asity Madagascar, BirdLife in Madagascar, which has been working since 2005 to save Tsitongambarika Forest.  This forest was the subject of the Birdfair mural painted by various artists who were exhibiting their work in the Art Marquee.

Birdfair can be a serious threat to the bank balance!  There are hundreds of stands selling the latest products for wildlife enthusiasts. From scopes to sculptures, binoculars to bird food, eGuides to eco-holidays, you can find almost anything you can think of.  Books tend to be Peter’s weakness, while June this year again came away with several items of clothing, mostly in her favourite colour – khaki!

Books - hard to resist!

A brand new book that seemed to be particularly well-received was Britain’s Birds: An Identification Guide to the Birds of Britain and Ireland, published by WILDGuides.  We haven’t always been keen on photographic guides but this one really is good with lots of useful text on identification features and there are surprisingly few missing species that will affect its use in Portugal.


Chris Packham was just one of several television presenters who were there, some giving talks, some signing books.  Chris took part in a well-attended debate about the issue of Hen Harrier persecution associated with driven grouse shooting and was promoting the petition that it is hoped will result in getting this subject a debate in Parliament.


Because we’re usually too busy talking, we don’t manage to find much time at the Birdfair for actual birdwatching.  We did see a Great Egret while trying out a Swarovski telescope but we can’t wait now to get back to some proper birdwatching in the Algarve.

The Farne Islands, Northumberland

“There is something really special about colonies of breeding seabirds and no matter how many times one sees them on film there’s nothing like actually being there to experience firsthand the wonderful smell and the noise.”  That’s what we wrote five years ago (!) when we visited Bempton Cliffs RSPB reserve in Yorkshire.

Guillemots

Ever since then it has been our intention to visit another seabird colony with Skomer Island and the Farne Islands at the top of our list.  However, crossing to offshore islands to see breeding seabirds isn’t entirely straightforward, particularly if your starting point is in Portugal!  We needed to find an opportunity during what is always a busy time of the year and then we needed some settled weather for the boat crossing.

Atlantic Puffins - very cute!

Finally, this year, we made it.  After just a few days back in the UK we headed north to Northumberland and the Farnes.  Located just off the coast near Bamburgh, the Farnes are well-known as the home of thousands of breeding seabirds and were featured recently on the BBC Springwatch programme, so they need little introduction from us.

Arctic Tern

We spent just three days in Northumberland visiting Holy Island as well as the Farnes.  Our trip to the Farnes was on a boat from Seahouses operated by Billy Shiel.  We landed on Staple Island and on Inner Farne and had a little over two hours on each.

Bamburgh Castle - we stayed nearby

Seahouses harbour

Puffins (about 40,000 pairs) and Arctic Terns (about 2,000 pairs) are probably the main attractions but in recent years there has been a big increase in the number of Guillemots with more than 50,000 individuals counted.  What a nightmare it must be counting that lot - we have difficulty counting just two or three thousand birds at Castro Marim!  In all, about two dozen species nest on the islands, a total that includes several passerines.

Grey Seal - one of the many hundreds

Guillemot - numbers have increased dramatically in recent years

Northern Fulmar - Found only on St Kilda until the 1900s, now 500,000 pairs nest around the British coast

European Shag - the name apparently means 'tufted'

Rock Pipit feeding young

Common Shelduck - just a pair or two breed

Razorbill - one of the world's less numerous auk species

Settled weather and a healthy supply of food are the two important factors that lead to breeding success and from all the signs the auks were doing well.  All three species were bringing in plenty of their staple diet of sandeels.  Arctic Terns, on the other hand, were having a more difficult time finding food, we were told.  What the eventual outcome of the season will be only time will tell.

Arctic Tern - the longest of long-distance migrants

Eider Duck - about 600 pairs breed

Black-legged Kittiwake - said to be the world's most numerous gull species

Red Squirrel - not on the islands but not far from Bamburgh

Being in such close proximity to so many birds (and hundreds of Grey Seals) was a memorable experience and we won’t want to leave it another five years before we enjoy again that distinctive smell and the constant calling of Kittiwakes.

Lesser Kestrels & Rollers

Regular readers will know that we are frequent visitors to the Baixo Alentejo.  We love birding around the Castro Verde area and have got to know it well over the years.


We are members of the Liga para a Protecção da Natureza (LPN) and often call in at their Environmental Education Centre at Vale Gonçalinho.  Recently we spent a morning there watching and photographing Lesser Kestrels and Rollers from one of the hides.  Using a hide in this way not only helps us obtain better photographs but importantly it avoids unnecessary disturbance to the birds, many of which were feeding young still in the nests.


Lesser Kestrels and European Rollers are both species that suffered population declines in the second half of the last century.  However, there are indications now that population levels of both have at least stabilised.


The main cause of declines has been habitat loss and degradation, primarily the result of agricultural intensification but also afforestation and urbanisation.  The replacement of grazed grasslands and dry cereal cultivation with vineyards and crops such as maize and sunflower has reduced the abundance and accessibility of the large insects, reptiles and small rodents that are their main food sources.  Pesticide use has also had a negative impact on prey populations.


Thanks to the efforts of the LPN an extensive area around Castro Verde was designated in 1999 as a Special Protection Area (SPA) under the EU Habitats Directive.  In this SPA extensive agricultural practices predominate with cereals rotating with fallow lands, resulting in an annual mosaic of crops, ploughed lands, stubbles and fallow areas. The fallow areas are generally used as pasture for sheep and cattle.  There are also holm oak groves and olive plantations.


Loss of nest sites has also been an issue for Lesser Kestrels and Rollers and the LPN has addressed this by building a number of walls and towers, which are effectively nest-boxes.  These can be seen dotted around the area with two of them at Vale Gonçalinho.  Many of the farms in the area also have nest-boxes.


Lesser Kestrels can return to the Alentejo as early as February; Rollers arrive later, in early April.  Whether this puts the Rollers at a disadvantage when it comes to selecting a nest-site isn’t clear but what can be seen increasingly is that both species face competition from a growing population of Western Jackdaws.  Reducing slightly the dimensions of the entrance to each nest-box might help keep the Jackdaws out but may also prevent their use by Rollers.

Migratory birds are potentially more vulnerable to environmental change than sedentary species; they rely on different, widely-separated sites for breeding and for over-wintering and others in-between for ‘re-fuelling’ during their migration.  In the past we have been able to find out about their movements through ringing but in recent years much more information has come from the use of satellite transmitters and geo-locators.  We now know, for instance, that the Rollers from Iberia that carried geo-locators took a westerly route in the autumn along the coast of West Africa, avoiding as far as possible the Sahara Desert, and then had a stopover in Cameroon or Congo before continuing to Angola and Namibia.  What a journey!


Although some Lesser Kestrels winter as far south even as South Africa, satellite-tracked birds from Spain went only as far as Senegal.  In January 2007, a single roost was found there containing an estimated 28,600 birds.  Imagine how many grasshoppers and locusts those birds were consuming and what the effect on the population would be if that food source disappeared for some reason.


In addition to Rollers and Lesser Kestrels, the Castro Verde SPA is home to Great & Little Bustards, Black-bellied Sandgrouse, Calandra Larks and many more species including numerous raptors such as Spanish Imperial Eagle and Montagu’s Harrier.  In late October, Common Cranes come from the north to spend the winter and flocks of Lapwings, Golden Plovers and Skylarks arrive.

Just writing about it makes us want to be there!
