Foulshaw to Leighton Moss

A seemingly near perfect day for watching butterflies at Gait Barrows near Silverdale today did nothing to allay my fears for the health of the UKs butterfly populations. Hot and sunny all day with not a breath of wind, we spent two hours at the reserve and saw just a handful of species in very small numbers. Three or four pearl-borded fritillaries, two brimstones, a couple of whites, a couple of blues and a speckled wood were just about the lot. Not a single Duke of Burgandy, no green hairstreaks and no dingy skippers. There were reports of a single Duke being seen earlier in the morning, but seriously has it come to this, one butterfly seen on a perfect day in the peak flight period? More worryingly there were periods of 15 minutes or more when I didn't see a single butterfly of any species, not even a white.

It was a similar story at Trowbarrow Nature Reserve near Leighton Moss, even less butterflies here though we did at least add a couple of dingy skippers to the list. Also here, no fly orchids. Earlier we went to Foulshaw Moss in Cumbria where there were loads of large-red damselflies and a few four-spot chasers, but not a single white-faced darter.

There were two ospreys on the nest at Foulshaw and a couple of tree pipits, three spoonbills asleep on the Eric Morecombe Pools where we also saw three lesser whitethroats together and a Cetti's warbler just outside the hide.

At Gait Barrows, the plastic Lady's Slipper Orchids are currently in full flower, and are about as wild as a pelican in Cornwall.

Year: 229 (Osprey, tree pipit, nightingale (Whisby Nature Park), bearded tit (Blacktoft))

Being an East Atlantic Island off the coast of North West Africa, Madeira has a hot, wet climate and is very green. However during our week long stay we found that there were actually three quite different major climates on the island, depending on altitude, with a fourth encompassing the eastern peninsular of Ponta de São Lourenço and the nearby island of Porto Santos (and probably also the Desertas Islands, though we didn't visit these). This summary is based on a single one week visit in the middle of May and  is probably completely wrong so see it for what it is, simply an attempt to summarise our holiday.

Sea level to 600m

From sea level to about 600m it was often cloudy or at least partially cloudy and not much warmer than an average UK summer. The vegetation here was very lush and a clear indicator of the amount of rain the island gets. Despite the mountainous nature of the whole island right down to sea level, it seemed at times that every inch of available land especially on the south side was tightly packed with the terraces of small holdings growing their own crops. The birds typical of this area included Maderian race kestrel, Atlantic canary and plain swift, though the latter especially was not restricted to low levels and could be found anywhere on the island, even around the highest peaks.

 Fig, 2 the cliffs are generally steeper on the northern coast but there are still plenty of terraces.

The exception in this lush, green, low level zone, and in fact as far as I could see, unique to the whole of Madeira, was the very arid Ponta de São Lourenço in the east which along with the nearby island of Porto Santos had a unique flora and fauna quite unlike anything else we found during our short stay, with plants such as iceplant Mesembryanthemum crystallinum and the endemic Berthelot's pipit. Both these species were also common on Porto Santos.

Fig. 4 Far from green and lush, the flora at Ponta de São Lourenço is unlike anywhere else on Madeira.

The middle level - 600m to 1400m

Between about 600m - 1400m there was often thick cloud. In this belt of cloud on the north side of Madeira is the magnificent laurisilva, a type of rain forest also known as cloud forest and for good reason. Its a very moist, humid place often covered in a blanket of fog or low cloud, with consistant temperatures throughout the year. The laurisilva of Madeira is a very ancient woodland, a UNESCO World Heritage site, dominated by a variety of laurel trees, with a splendid understorey dominated by ferns and bryophytes, and is the largest remaiming example of a forest that once covered large areas of Southern Europe. Endemic birds such as Madeiran firecrest, Trocaz pigeon and the Madeiran race chaffinch are common here.

Fig. 7 The laurisilva is not always in cloud, but this bit was 30 minutes after I took the photo!

The mountain levels - 1400m to 1860m

Above 1400m we were often (though not always) above the clouds and into a mountain climate. However, despite getting up to around 1800m (around 6000ft), I didn't find any plants that I would recognise as tyipcally alpine apart from the occasional Saxifraga pickeringii or the spectacular Aeonium glandulosum. Perhaps this far south the mountains just aren't high enough for alpines. Typical plant species here included Erica arborea, a type of heather also known as tree heath which typically can grow up to 4m tall but sometimes can reach 7m. I've been above the clouds before in the mountains, in the Alps for example, but this was different, this wasn't just the occasional cloud drifting past below, this was often a whole belt of cloud for as far as the eye could see, the sort of view you get from an aircraft when approaching Manchester on your way home, bright blue sky above and dazzling white cloud below, the difference being that in this case you could also see islands in the clouds as the various peaks broke through. As you might expect, just like in Manchester, the best of the Madeiran weather was above the clouds, hot and sunny. This is where you had the best chance of getting a tan, or worse!

Fig. 9 Pic do Arieiro. High above the clouds and home to the oceanic Zino's petrel.

Whilst we are in the high mountains it's worth mentioning another reason why these high peaks are different to any others that I have encounted, in that they hold the entire world population of one of the most Oceanic and endangered seabirds in the world, Zino's petrel. It's hard to put into words how awe-inspiring it is to be above the clouds on a bright moonlit night watching and listening to Zino's petrels flying around their nesting burrows, birds which otherwise you would only expect to see in the middle of the Atlantic ocean. Only around 70 pairs in existance, and they all nest here on Pic do Arieiro, above the clouds on Madeira and they have an eerie call, typical of so many of these sea birds at their burrows. With so few other birds up here, it's amazing to think that without doubt the evocative sound of Pic do Arieiro is the call of such an oceanic bird! Unfortunately, unless you're there at night, around midnight, you'll never hear it.
 
A few bryophytes and ferns of the laurisilva

However, exciting as these rare endemic sea birds might be, it is not they or any other bird which makes Madeira so important and special, it's the laurisilva forest and the flora, bryophytes and ferns it supports. While we were in Madeira I wrote many blog posts regarding the other flora and fauna that we saw and you can find them all by simply scrolling down the page. For the rest of this post I'm going to concentrate on the bryophytes and ferns because they deserve a special mention of their own and they are so often overlooked by the overwhelming majority of visitors, who actually probably consider the low cloud and fog an inconvenience to the their holiday rather than embracing it and recognising that it is the cloud and the moisture which is what makes Madeira and in particular the laurisilva such a special place.

There are so many endemic species on Madeira that I can't possibly put a name to all of the plants below, and it would be foolish to try. I'm not even sure that a book exists to help me name them, and I'm wary enough of putting names to British bryophytes and ferns let alone those in Madeira! Even so, I'll try to comment of those which look familiar (even if in reality they're not!). Please note, where I've suggested a name below it does not mean that it is that species, just that it looks a bit like it! I didn't even have a hand lense with me to help. The birding equivalent would be for me to say that a Fea's petrel looks a bit like a Zino's petrel without the aid of binoculars. Don't take it literally!

Looks like a thyme-moss.

Looks a bit like Plagiomnium undulatum.

Looks a bit like Mnium hornum.

I'm not sure what this is but I only found growing on waterfalls and it is the species I was photographing in the photos of the bryophyte wall above.

Some type of bristle-moss? I love the capsules they really look alien like!

This moss was not in the laurisilva, it was at an altitude of about 1800m in the mountains.

Ferns

The Laurisilva and Teixeira

We started off this morning at Ribeiro Frio in the heart of the ancient Laurisilva forest of Madeira. It's classed as rainforest and true to form, just like the tropical rainforest of Queensland Australia, it was more or less completely green and at times seemingly birdless.

What it did have was a lot of ferns  and bryophytes and a particular abundance of liverworts, and this was enough to keep me entertained. I'll be doing a separate blog post on the ferns and bryophytes I saw in Madeira in due course.

I probably only saw about five species of birds, and the most abundant was the beautiful Madeiran Firecrest.  We completely failed to see the endemic Trocaz pigeon, though to be fair I was looking at the bryophytes most of the time and whole flocks of the pigeon could have passed by and I wouldn't have noticed.

Madeiran speckled wood Pararge xiphia. Unfortunately I was unable to get an open wing shot of this butterfly but it can still be easily identified from the the photo.

Note the convex edge to the outer margin of the forewing and also the white mark halfway along the hindwing costa. Both of these features make this a Madeiran speckled wood, which is also a larger butterfly than common speckled wood Pararge aegeria aegeria which also occurs on Madeira . 

Speckled wood Pararge aegeria aegeria. This is the same species as we get in the UK but confusingly this is the Madeiran race. Note the concave edge to the outer margin of the forewing.

Madeiran Cleopatra Gonepteryx maderensis, possibly a female. This is a declining and endangered species on Madeira. I've never yet managed an open wing shot of any species of brimstone so this is about as good as it was ever likely to get!

Clouded yellow Colias croceus.

Eventually we moved on to Santana and then up into the mountains, above the annoying clouds and mist, and up into the sunshine. We were close to the summit of Pico Ruivo and only a few miles walk to Pic do Arieiro.  It was beautiful up here, lots of butterflies flitting around as well as plain swifts and Berthelot's pipits. Oh and a Trocaz pigeon flew across the road in front of the car on the way up. A great end to the day.
