Coming soon to a golf course near you?

This week, the American Birding Association Checklist Committee voted unanimously to accept the Egyptian Goose (Alopochen aegyptiacus) as an established exotic in south-eastern Florida and added it to the official ABA Checklist.  Birds have been present in Florida for 20 years and there have been numerous records of breeding; without doubt the population is now self-sustaining. Although the species is found elsewhere in North America (e.g. Arkansas, California and Texas) those populations are not yet regarded as being established and presumably therefore are not ‘tickable’ but it seems likely to be just a matter of time.

Egyptian Geese were introduced to Britain as early as the 17th century and have bred in the wild for over 200 years.  Until comparatively recently they were more or less confined to Norfolk but there has been a gradual increase in numbers and fieldwork for Bird Atlas 2007-11 has shown a significant recent range expansion including scattered winter records from Shetland, west Wales, Cornwall and even Ireland.

In Holland, too, there has been considerable expansion and the population there has been estimated at about 11,000 pairs, or 50,000 individuals post-breeding.  There are also breeding populations in France and Germany.     

This week’s Noticiário Ornitológico included a record of 13 Egyptian Geese at the Alqueva reservoir near Évora in eastern Portugal, close to the border with Spain.  This continues the trend that we have seen this year for increasing reports of this exotic species in Portugal.  In June and July birds were seen in the Algarve at Lagoa dos Salgados.  These latest birds were seen on 23rd August south of Roncão and they represent the largest flock seen so far.  Not so long ago reports of Egyptian Geese were referred to as escapes from captivity but this description has now been dropped and the reality surely is that these birds are arriving from the established and expanding feral populations in Northern Europe.  

Two of the most obvious field marks of the Egyptian Goose are the chestnut eye patches surrounding its yellow eyes, and a brown chest patch.  There is also a brown stripe that forms a collar around the nape of the neck.  The bill is pink, with a black tip and a dark base. The male has green secondaries, but a large portion of the adult wing is white. The white usually remains hidden when the bird is at rest, however, the white wing feathers are easily seen when the bird is in flight. The under tail coverts are cinnamon colored:  the upper tail is black.  The sexes look alike, but the female is slightly smaller.  Juvenile birds are similar to adults but lack the distinct facial markings.

Of course, the Egyptian Goose isn’t really a goose at all; it is believed to be most closely related to the shelducks (genus Tadorna) and their relatives, and is placed with them in the subfamily Tadorninae.

Egyptian Geese are native to sub-Saharan Africa where they are widespread and numerous; we have seen them on most of our visits to Africa.  In many areas they are regarded as agricultural pests because they sometimes feed on or trample crops and in South Africa they occur in large numbers on golf courses where they cause physical and financial damage to the courses and are a nuisance to golfers and golf course managers.  In Holland they are reported to be aggressive towards breeding waders.  We do wonder therefore whether we should be looking beyond the novelty of having these birds arriving and instead considering the potential for them to quickly become an unwelcome nuisance.

Norfolk & Lincolnshire

It would seem that on Sunday the only rarities seen along the North Norfolk coast were June and Peter.  However, although there was nothing very unusual to see, we had a decent day’s birding and the weather was kind to us throughout.  We were strangers in what was once very familiar territory, visiting for the day with friend Keith Lievesley. 
 
We began at Titchwell (RSPB), moved on to Cley Marshes (Norfolk Wildlife Trust) and later on the way back had a good walk over Blakeney Freshes (National Trust).  Each area showed signs of the damage caused by the exceptional storm surge that took place on 5th December last year but it was remarkable to see how well they seem to be recovering.

A fairly relaxed day in this relatively uniform habitat produced a modest 72 species.  One of the most numerous of the waders was Ruff and it was the only one that we photographed.

So infrequent are our visits to Titchwell that we hadn’t previously seen the much-maligned Parrinder Hide.  We had read about it and seen it described as, amongst other things, “too posh”, “ridiculously expensive” and “a monstrosity” and certainly it does seem a bit over the top.  Just the size of it was a surprise!  Who would have imagined something like this when Norman Sills first came to Titchwell as the first warden in the early 1970s?

The hides at Cley Marshes are probably more to our liking - Daukes Hide is surely a much more attractive structure.  However, the visitor centre here, like the Parrinder Hide at Titchwell, is also a building that divides opinion.  The mere fact that it can be found on TripAdvisor is for some people enough to view it as a tourist attraction in its own right and it certainly houses a seriously commercial operation.  It was the first time we have been asked to sign for Gift Aid when paying an entrance fee for a reserve - but why not?

Cley Marshes Visitor Centres - the new and the old

It was the first time we have looked out to sea from Cley and seen not just passing seabirds but also about 90 wind turbines!  We still can’t bring ourselves to like them at all!  We preferred to look east along the shingle bank towards Sheringham.

Several times during the day we met people who have been birding with us either through Avian Adventures or Algarve Birders.  They were all first encountered at Titchwell, which has now perhaps replaced the East Bank at Cley as the place to bump into people you know or at least recognise.

The East Bank

After our walk at Blakeney we drove to Wells-next-the-Sea and as we struggled to negotiate the narrow section of the A149 through Stiffkey we were looking forward to fish and chips.  When we arrived, long queues at both shops on the front were another reminder (as if we needed one!) that this was a Bank Holiday weekend.  We quickly decided that continuing to Hunstanton might be a better plan and so it proved although we cut it fine, being the last to be served before closing time at the excellent Supafry in Greevegate.

Monday could not have been more different; it was a public holiday and the weather performed accordingly, pouring rain no doubt ruining countless events that had been a long time in the planning.  We were not immune and suffered a good soaking during our visit to Deeping Lakes, a Lincolnshire Wildlife Trust reserve, near Stamford.  We took a circular route through the reserve and along the bank of the River Welland, sheltering in a couple of hides while looking at various gravel pits where Great Crested Grebes were feeding young and Cormorants also seemed to be finding plenty of food.  An artificial Sand Martin nesting bank would have been more interesting to see earlier in the summer and we would love to see one like it in the Algarve.  June did at least get to see one of her favourite Green Woodpeckers, so our trip wasn’t all in vain.

This sign at Deeping Lakes appealed to us pedants.    

Birdfair 2014

We’ve just enjoyed another great weekend at the British Birdwatching Fair at Rutland Water, three days of talking birds, travel and photography with a bit of cricket and football on the side!

As usual we were on the Avian Adventures stand promoting tours all over the world but there were plenty of opportunities to talk about the Algarve ("lots of birds and sunshine and less than three hours away from most regional airports in the UK")!

It was really nice to meet up again with so many friends, a great number of them, like Mavourneen Pearce (above), from overseas.  We re-lived quite a few past birding trips but also made plans for several more in the next few months.

The cover of the Avian Adventures brochure for 2015 features a Collared Araçari photographed in Honduras by James Adams.  Here Gerry Griffiths drinks a toast with James to the success of next year’s tour there.  See here for details!

We were in Marquee 3, seen here during a relatively quiet moment late on Sunday afternoon.

At the 2011 Birdfair we sponsored the BTO’s satellite-tagged Cuckoo, Chris, not realising at the time that it was named after Chris Packham.  Anyway, it proved to be a good choice as Chris is the only one of that year’s Cuckoos still to be transmitting.  Chris is currently in Italy on the way back to spend the winter in Africa and we have our fingers crossed for his continued survival.  It’s great that our stand in Marquee 3 is directly opposite that of the BTO as it gives us the chance to pop across during any quiet moments to talk to their staff who are working on projects such as this.

It looks as though June is about to be attacked by Findlay Wilde's Hen Harrier!  There were frequent reminders of last week’s Hen Harrier Day and if you haven’t already signed Mark Avery’s petition, you really should.  It's good to see that well over 15,000 people have so far signed.

Television presenter and President of the BTO, Chris Packham, has been a great supporter of the Hen Harrier campaign; he signed countless copies of his latest book.

The SPEA stand was one of several promoting Portugal and its birds.  Currently SPEA is mounting a campaign against the illegal trapping of birds, which is becoming an increasing problem in Portugal.  Details of how you might make a donation to help with this campaign can be found here.

Amy and Sering Bojang enjoying a joke with Neil Glenn - Sering’s combination of rubber boots and sunglasses rather summed up the weekend weather.  Neil was much involved in collecting football strips for Kits 4 Causes.

Although it’s called Birdfair, increasingly we’re seeing wildlife other than birds being featured.  Butterfly Conservation, Buglife, Bat Conservation Trust and the British Arachnological Society were just some of the organisations trying to get birders to look at a bigger picture, which most of us probably do.

There is a really good nature reserve and lots of birds at Rutland Water or at least that’s what we’ve been told!  Year after year we go the Birdfair but somehow never seem to find time for any birding.  Nevertheless, we are already looking forward to Birdfair 2015!

Magpies

How well do you know your magpies?  The three photographs below show three different birds; they were taken on three different continents.  Can you identify them?  We can’t say that they are three different species…but they might be!  Even those who identify birds by examining their DNA don’t seem to have reached a conclusion, so what chance for us?  Maybe you can at least suggest where each photograph was taken.

Here is another magpie.  This one’s easy - it’s obviously a Yellow-billed Magpie Pica nuttalli, which occurs only in California and which it seems everyone agrees is a distinct species.  Yellow-billed Magpies have declined in recent years with 50% of the population reportedly killed by West Nile virus between 2004 and 2006.

Not all magpies are black and white birds with long tails!  Below we have Red-billed Blue Magpie Urocissa erythrorhyncha from Asia, photographed in China and an Iberian Magpie Cyanopica cooki or perhaps an Azure-winged Magpie Cyanopica cyanus, photographed in Portugal.  Whether you choose to call the latter an Iberian or an Azure-winged will depend on which taxonomy you’re inclined towards.  We have blogged here on this subject in the past.

And not all black and white birds with a long tail are magpies!  Below is a Magpie Shrike Urolestes melanoleucus, a fairly common bird in savanna-woodland in eastern and southern Africa.  The photograph was taken in Tanzania.  Presumably the English name was given to the bird by a 19th Century European explorer who saw some similarity to the plumage and shape of Pica pica. 

Basket dweller

Cisticola juncidis is a very common species in the Algarve, one that we can expect to come across almost every day.  Although it is one of our smallest birds, not much bigger than a Wren, its aerial displays and distinctive but monotonous ‘dzip…dzip…dzip…’ song makes it hard to miss.  It mainly occurs in open, grassy areas, a habitat that is still plentiful.

But what should we call it?  You can still find field guides that use the English name Fan-tailed Warbler and rather surprisingly that is what you will also see on the BTO website.  It is little wonder then that we come across lots of birders who continue to refer to the bird by what we woud argue is a potentially confusing and therefore out-dated name. 

Surely there should only be one species in the world called Fan-tailed Warbler and that name belongs to Basileuterus lachrymosus, a bird that inhabits Central and North America. The counter argument, of course, is that most birders in Europe aren’t even aware of this New World species and that when one is talking about a bird this side of the Atlantic the meaning is obvious, context is everything.  

Whatever your view, it does surely seem more normal these days to use the name Zitting Cisticola.  Certainly, that’s what you will find in most modern books and recent field guides.  It is the name adopted by all of the recognised authorities, BirdLife, IOC, BOU, etc, etc.  and with roughly 50 other species in the genus Cisticola all having Cisticola as part of their English name, it does seem sensible that C. juncidis should conform.

We have a feeling that at least some people cling to Fan-tailed Warbler and hesitate to adopt the more logical name simply because they’re not comfortable saying Zitting Cisticola, they’re not quite sure how to pronounce it.  It’s hard not to have a little sympathy with that.  Someone even suggested to us that it sounded too much like a skin complaint! 

We tend to refer to the bird as a ‘sis-TIC-ola’ and this is the pronunciation favoured by Wikipedia and others.  However, it’s not hard to find alternative guidance and another example has just come to our attention, in the recently published Latin for Bird Lovers by Roger Lederer and Carol Burr.  In this we find ‘sis-ti-KO-la’ as the suggested way to say it.  It certainly trips off the tongue more easily than ‘sis-TIC-ola’ perhaps because it brings to mind that well-known carbonated soft drink!

Our conclusion would be that both ‘sis-TIC-ola’ and ‘sis-ti-KO-la’ are acceptable pronunciations but surely it is time we abandoned Fan-tailed Warbler.

The ‘Zitting’ part of the name of course refers to the birds’ song.  It follows other members of the genus that have similar names descriptive of their vocalisations: Bubbling, Chattering, Churring, Chirping, Croaking, Piping, Rattling, Siffling, Singing, Tinkling, Trilling, Wailing, Whistling and Winding are all names given to cisticolas!  The word cisticola apparently derives from cista, a woven basket and colo, meaning to dwell and refers to the birds’ basket-shaped nests.

We say that there are ‘roughly 50 other species in the genus’ because almost inevitably there isn’t taxonomic unanimity.  For the same reason, we should also say that there about 17 or 18 subspecies of Zitting Cisticola, which is the most widely distributed of the genus, occurring in southern Europe, Africa, southern Asia and northern Australia.  Although there has been a northward expansion of the species range in Europe, they are susceptible to hard winters and there have been only a handful of records in Britain.

Colourful Quartet

Our recent visit to the Castro Verde area produced most but not all of the regular species that visitors ask to see.  We didn’t miss many but unfortunately, as the season progresses some species become more difficult to find.  Birds that only a few weeks ago were singing and displaying, defending a territory or trying to attract a mate are now feeding young and trying hard not to draw attention to themselves or their offspring.  At the same time, the grass and other vegetation has grown taller and there are plenty of places to hide away.  It makes our task much harder!

Fortunately, in the same area where those uncooperative Little Bustards are lurking and where the Black-winged Kites have taken their young out of sight, there are four much more easily seen, brightly coloured species that will, at least for a few minutes, brighten anyone’s day.

Our experience is that Hoopoe, European Roller, European Bee-eater and Common Kingfisher are among the most popular birds that we find for our visitors.  Maybe it’s because of their flashy plumage or perhaps simply because they’re all instantly recognisable!

Each of these four species is the only representative of its family to occur in Western Europe other than as a vagrant but they are clearly related to each other and have much in common.  Have you noticed how they always appear bunched together in your checklist between the swifts and the woodpeckers?  And it’s not unusual to see them sharing a page in a field guide!

A Field Guide to the Birds of Britain and Europe (Peterson, Mountfort & Hollom) 1954

All four of them nest in cavities; Hoopoes and Rollers like to nest in holes in trees but most of the Rollers we see nest in artificially provided sites and Hoopoes also will occasionally take to nest boxes; Bee-eaters and Kingfishers on the other hand usually excavate a hole in a vertical bank and Bee-eaters will also use a hole in sloping or even flat ground.

We tend to think of Rollers and Bee-eaters as migrants and Hoopoes and Kingfishers as resident species but that really isn’t the whole story.  It’s true that Rollers and Bee-eaters do spend only the few months of the breeding season in Portugal before heading south to winter in Africa but Hoopoes and Kingfishers also make seasonal movements.  Of course, these movements are less obvious as they don’t involve the whole population; many Hoopoes do leave us during the winter but always some remain.  On the other hand, the number of Kingfishers in the Algarve increases in the autumn as birds arrive from further north and they are commonly seen from September through to February.  

If you would like to see all four of these birds during one visit to the Algarve, make sure to plan your trip between late April and August.  Also bear in mind that although Rollers can sometimes be seen as migrants in the Algarve, mainly in the west and in August, they do not breed here and a trip to the Alentejo will usually be necessary to be sure of finding them.

Hot Summer Days

We don’t expect to have much rain at this time of the year.  The average amount for the month of June here in Tavira is only about 8mm.  There was a brief shower a few nights ago but any trace of it was gone by morning and many people won’t even have noticed it.

Recently, temperatures have been rising to around 25ºC most days but the forecast shows an expected high at the weekend of a toasty 32º.  Everywhere the land looks baked and parched, a situation that is unlikely to change until well into September at the earliest.

If you’re a House Martin wanting mud for your nest, it’s definitely not much fun!  Mud is in short supply!  Of course, the breeding season for House Martins started early here; many birds were back in February and some didn’t leave at all, managing to find enough insect food in the Algarve through the ‘winter months’.  By now most will have raised at least one brood if not two.  But still there are birds that are busy collecting mud.  Probably they are repairing nests rather than building new ones from scratch, but who knows?

We always enjoy watching and photographing birds that are attracted to fresh water, whether they are collecting mud or just drinking and bathing.  Migration seasons give more chance for something unusual to show up but even now there can be a good selection of species.  The common seed-eating finches, Serins, Goldfinches, Greenfinches and Linnets, are the most regular but, as well as the House Martins and an occasional Barn Swallow, we have had Spotless Starlings, Blackbirds, House Sparrows, Collared Doves, Azure-winged Magpies and Yellow Wagtails.

It’s been both enjoyable and frustrating to sit watching these birds and at the same time listen to Nightingale, Blackcap, Cetti’s Warbler, Reed Warbler and Common Waxbill, all of them just a few metres away but none showing any inclination to come out for a bath and a photo session!

We haven’t been spending all our time cooped up in the car taking photographs - for one thing, it’s far too hot!  We’ve also spent time in the Castro Verde area watching Rollers, Lesser Kestrels, Collared Pratincoles and more, many of them feeding young.  And yesterday we helped with the monthly count of the birds on the Castro Marim Reserve, where the highlights as far as numbers are concerned were 1,200 Greater Flamingos, 780 Black-tailed Godwits, 147 Slender-billed Gulls, 116 Shelducks, 212 Black-winged Stilts and 175 Avocets.  As well as counting, we managed to read quite a number of colour-rings, mostly on Spoonbills and Audouin’s Gulls.
