birding at Aghia Triada

‘Aghia Triada’ is ‘Holy Trinity’, and it’s a monastery on Akrotiri. I went there not just to look at the monastery, but mainly to do birding.

It was a good birding day, I’m pleased to say. Lots of birds, but the most notable were the black-headed race of Yellow Wagtail, Golden Oriole and two which are new for me: Black-eared Wheatear and Collared Flycatcher.

Also lots of flowers; my first orchid of the trip, a serapsis of some kind, and some extraordinary huge dark purple arums that looked like something from Day of the Triffids. So that was all good.

Cloudy all day, which was good for my personal comfort but not so good for photography.

First Annual Blogger Bioblitz

blogger bioblitz buttonJust a heads-up for anyone who’s interested: the First Annual Blogger Bioblitz, ‘where bloggers from across the country will choose a wild or not-so-wild area and find how many of each different species – plant, animal, fungi and anything in between – live in a certain area within a certain time’ will be run from April 21-29.

You can read the annnouncement here, and they’ve set up a discussion group on Google Groups here.

I’m thinking of participating but some kind of weird bug in Google Groups means I haven’t registered yet. I’m going to be in Crete at the time, and I’ll be taking a bird guide (obviously!) as well as a guide to the wild flowers of Crete, but I won’t be able to do any insects or fungi or anything. I’m a little intimidated by the expertise of most of the people taking part, but on the basis that it’s an exercise in mass-participation rather than a rigorous scientific study, I thought I’d do what I could.

bird of the year 2006: best performances in a supporting role

Best Plant

All those rainforest plants were nice, and I enjoyed taking wildflower photos while I was in Spain. But, not least because it’s nice to pick a winner that I can actually identify, I’m going for the Galapagos Prickly Pear, Opuntia echios. On islands where there are giant tortoises and land iguanas, they’ve evolved woody trunks and have fierce spines; on other islands they don’t have the trunks and they have soft bendy spines. And I enjoyed taking macro pictures of them, like this bit of trunk:

Best Insect

There were some great butterflies in the jungle – notably spectacular blue morphos – and a particularly striking leaf-mimicking moth, but my winner is the Painted Locust.

Best Invertebrate (other)

The shortlist would include the tarantula I saw in the rainforest – a first for me – the Chocolate Chip Sea Star and Galapagos Slipper Lobster (curious-looking and tasty), but the undoubted star in this category was the Sally Lightfoot Crab.

Best Fish

Piranha deserves a mention, even if I didn’t see one actually in the water, and it was very gratifying to see sharks swimming long with just their fins sticking out of the water, like what they do in the movies. But I had two special fish in the Galapagos this year. For the first, we were anchored off an island at night. Lots of fish had been attracted to the boat’s lights, and they in turn had attracted sea-lions and turtles, so we were watching them splashing around in the phosphorescence. Every so often there would be a splash where one of the sea-lions was swimming and a trail of phosphorescence would shoot off, zig-zagging over the water. It took me a few occasions to realise that they were flying fish. Which was cool.

The other came when I was trying to track down something splashing in the distance — I thought it was probably a dolphin, but I kept missing it or not seeing it well enough to identify. When I finally got binoculars on it, I was stunned to realise it was a manta ray leaping clear of the water. Later on in the trip we saw them a bit closer, and it was an absolute thrill. They don’t look like the most aerodynamic beasties, and it’s extraordinary seeing them launch themselves and twist in midair before crashing back into the water. Manta ray and flying fish are both species I’ve wanted to see for a very long time, but the manta wins the award for best fish of 2006.

Best Amphibian

A teeny-weeny poison arrow frog in the rainforest.

Best Reptile

It’s all Galapagos in this category: the shortlist is Green Turtle, Land Iguana, Marine Iguana and Giant Tortoise. It’s always nice to see turtles, and especially to swim with them, but I’ve seen them before. The three Galapagos specialities are all among the most desirable reptile species in the world. The tortoises are fun, and even bigger than you expect; the land iguana is a striking-looking beast. But it’s the marine iguanas which really stand out.

The fact that they’re lizards which swim out to sea to feed would almost be enough to win them the category, but they’re one of the continual pleasures of visiting the islands; you have to be careful not to step on them, they’re so indifferent to your presence. And you see them in great scaly drifts draped all over the lava, occasionally sneezing out the excess salt or aggressively nodding their heads at each other but mainly spending their time basking in the sun like hungover English tourists. They have a rugged, rock-hewn saurian quality that makes them seem like survivors from a distant epoch, which is misleading since in fact the islands, by evolutionary standards, are relatively young.

Best Mammal

I saw squirrels and monkeys in the jungle, and in another year those might be in contention for Best Mammal. And then there was the dozens and dozens of Bottle-nosed Dolphins and False Killer Whales that turned up unexpectedly one morning and which swam around the dinghy for us to see, or the dolphins that rode the bow-wave of the ship, jumping and twisting. But there can be no doubt that the Galapagos Sea Lion is the winner this year. It’s such a treat to be able to just wander past these animals and have them pay you no attention but just get on with playing, suckling their pups (cubs?) or most often just lying around.

The babies are fantastically cute, and the males are imposing, but the general impression is big furry bolsters — until you’re snorkelling along and suddenly a sea lion swims past underneath and looks up at you, and you realise that they’re sleek, graceful, muscular, and quite large. I found having a sea lion stick it’s nose up to my snorkel mask exciting but just a little bit intimidating. I think that’s a good thing; it’s good to be reminded from time to time that animals are not toys or pets or little furry people, but something quite alien. We tend to see animals in a human context, as food, pests, entertainment, ‘endangered species’; it’s good to feel like the outsider in their environment.

Best Ecosystem

Andalusia in spring was gorgeous. The marsh itself, with nightingales and Cetti’s warblers singing in every bush, and the sun on the water; the dry scrubby stuff with Dartford Warblers and Red-legged Partridge, and possibly best of all, sandy pine woodlands, with the amazing contrast between the glare of the noon sun and the deep shade, and the noise of bees and crickets in the heat.

And the lava fields of the Galapagos are like nowhere else on earth. It’s not a gentle landscape — uneven, sunbaked rock with the occasional cactus or thornbush hanging on as best it can — but the ripples and flows of the lava are endlessly fascinating. It’s geology made ridiculously simple; you can just look at it and see how it formed. And it brings home the endless capacity of life to find a way to live in unpromising places; the cacti colonising the bare rock before soil has a chance to form, the mangroves on the beach, and sea lions, seabirds, iguanas, sea stars, crabs and fish on the little fringe where the land meets the sea. And it’s not just interesting; it has a real beauty to it. It’s dramatic and odd and textured.

But my ecosystem of the year was none of those; it was the Ecuadorian cloudforest. I mean, it’s a rainforest with spectacular mountain views: how can you go wrong? The birds are actually sometimes at eye-level, unlike the lowland forest, and the temperatures are very moderate, even chilly sometimes. The humidity is such that plants just grow everywhere; you get the feeling that if you nodded off up on the mountain, you’d wake up covered in moss. There are trees up there which are so covered in epiphytes, bromeliads, moss, ferns and creepers that you can only roughly tell where the trunk and branches are. And every so often the cloud closes in, and instead of spectacular vistas, the world shrinks right down so it’s just you and the mist and a lot of weird calls from invisible birds.

I don’t have a photo which does justice to the vegetation (my camera batteries died), but here are some mountains:

In the Galapagos

I´ve got a couple of hours in Puerto Ayora (on Santa Cruz, in the Galapagos), so I thought I´d post a quick note.

I can recommend the Galapagos. For a start, the landscape is more varied and more beautiful than I expected; somehow in my head it was all rocks, but from island to island the colour of the rocks and soil changes, the vegetation varies – I mean it´s mainly pretty arid, and so it´s lots of cactus and thornbushes, but one island will be an expanse of rippled black lava with a few small cacti, and another will be densely covered with bushes. This afternoon we´re going to the highlands for the first time, where it´s actually quite green.

We´ve seen most of the Galapagos specialties now – the two iguanas, the flightless cormorants, the finches (5 of the 13 species so far). Wild giant tortoises this afternoon. I´ve snorkelled with sea-lions and penguins and turtles, I was particularly thrilled wih the penguins.

Actually though, apart from the special Galapagos stuff, it´s been nice just being at sea. I hadn´t really thought about it before I came, but it´s great just being able to watch shearwaters and storm-petrels from the boat. And we´ve had dolphins riding the bow-wave of the boat. But almost my most exciting marine sighting was watching manta rays jump clear of the water and tumble back with a big splash.

The famous tameness of the animals is quite interesting; I expected it of the endemic species that have evolved in an environment without predators, but species like Great Blue Heron, which are wary of people in the rest of the Americas, have been letting us get within about 10 feet. We watched one grab a newly hatched turtle from below the sand.

So it´s all good.

FSotW: Digital Dendrology

Sorry, I forgot yesterday, so Flickr set of the week is a day late, but worth waiting for. It’s the remarkable Digital Dendrology by phyredesign.

“I’m fascinated by how things are structured in nature. This year, I have begun taking samples from the branches I collect, and preparing slides for viewing under a microscope. After identifying the type of tree to which the branch belongs, I use a digital camera attachment on my microscope to photograph the samples. Piecing together over fifty photographs for each sample, each final image is a 100x magnification of a glimpse of life not seen by the human eye alone. They become abstract structures reminiscent of any number of things.”

More parasitic plants



Snow plant, originally uploaded by Ken-ichi.

Not that parasitic plants have exactly been a running theme on this blog, but I have mentioned broomrape once. Anyway, a photo came up on the ID Please group in Flickr, and it piqued my curiosity enough to poke around with Google and decide it was a Snow Plant, Sarcodes sanguinea. The picture above is a different shot of the same species. Apparently they don’t actually parasitise plants directly, they get their nutrients from fungi which themselves are growing on the roots of trees. Ain’t nature marvellous.

The other remarkable thing about this particular species is that it’s a member of the Ericaceae; i.e. the same family as the heathers, blueberry and rhododendrons.

And that in turn reminded me of a species of orchid I saw in Provence two or three years ago:

That’s Limodorum abortivum, or Violet Limodore; and like the Snow Plant it’s a myco-heterotroph, which is apparently the term for plants that feed on fungi that feed on plants.
