Some nice photos

It’s been a busy winter. It’s not that I’ve not had the time to post something on the blog, the problem is that there has been so much stuff going on that I’ve not been able to sum it up. It’s quite easy actually: Borolo’s sheawater things in the Canary Islands and twitching in Catalonia.

The project with the shearwaters is going well and the first two birds have been successfully tagged, both reporting data about their unknown foraging range. Since all the information about this is already in the project’ blog post, I’ll focus on some other experiences. First of all, while trying to mistnet shearwaters, we caught several Grant’s storm-petrels. This species is not formally described yet and… oh wait, Stephen already spoke about that too!

Should I write about the twitching then? Much ink has been already spilled about the Brown shrike at Ebro Delta, the Isabelline shrike at Marjal d’Almenara, the Pygmy cormorant and the Ring-necked duck at exactly the same locality in Aiguamolls de l’Empordà and the local megas (almost first twitchable ever) Rock pipit and Purple sandpiper (both at Ebro Delta and surrounding areas).

So, what’s left? 3 months without posting and you end up showing some lichen photos to add some freshness. Here they go, Lepraria sp. and Xanthoria sp.:

Both photos were taken at Fuerteventura. The Eastern Islands are bright like I had never seen them before, both full of flowers that create a stunning carpet. Keeping in mind most of these plants are endemic, the ecological benefits of this year’s rain are invaluable. The photo shows the currently violet surroundings of El Golfo village, due to the flowered Echium lancerottense.

Fuerteventura shows a similar aspect, but what always impresses me the most are the sharp colors of the spurges Euphorbia canariensis. While Stephen was chasing some stonechats, I was taking photos of the scene.

So this has ended up being a crappy post with no information and just some nice photos. Trust me, it’s not been that bad…

Interesting shearwater

17 12 2012

“I believe in a long, prolonged, derangement of the senses in order to obtain the unknown.”

– Jim Morrison

A new project has born in the Canary Islands! I am talking about Cetavist, a net of observers on board the ferries between islands. The project is carried by the University of la Laguna and its main purpose is to describe the distribution of both cetaceans and seabirds within the Canary Island archipelago. In the last years, there have been many changes in both the occurrence and abundance of some of the species such as Bryde’s whale and Barolo’s shearwater. To describe that processes, it’s important to be prospecting almost every week, so the project count with the help of volunteers. If anyone is planning a birding trip to the Canaries and wants to try the Barolo’s shearwater (nowadays the hardest bird of Spain!) from the ferries (the best ones are between Tenerife and La Gomera and between Tenerife and El Hierro), please contact me and you would obtain free tickets! The only thing you have to do in exchange is to count birds and cetaceans and take the position of each sighting. The datasheet is very simple… You can check the news about the project (in Spanish, for the moment) in the new blog cetavist.blogspot.com.

The coordinators of the project have been all the last week aboard, evaluating if it was possible to detect animals from the fast ferries of the Fred Olsen company. The results were the expected and we managed to see Bryde’s whale, Short-finned pilot whale, Short-beaked common dolphin, Bottlenose dolphin and Cuvier’s beaked whale. Birds where also present, although they were very scarce. We saw at least 4 Barolo’s shearwaters and 1 Leach’s storm-petrel.

However, the best sighing of the week was that interesting shearwater. It shows a Barolo’s-like structure, maybe a little bit more long-tailed and thick-billed. These features match both Audubon’s and Cape Verde Little shearwater, as well as the coloration. The dark leading edge in the underwing is larger than in Barolo’s, the face is black and the upperwing lacks the pale panel in the GCs.

All these features seem to rule out Barolo’s shearwater and point to the other 2 candidates, which would be both a first for Spain. Of course, comments are welcome!





Start!

“To step out into the dark
Now I’m ready”

– Ready to start, The Arcade Fire

Tomorrow is the day! I take off at 18:45, landing at Vigo airport at 9:30. The whole day feeling nervous, anxious… The Cornide de Saavedra, an old but warm research vessel, will be my home in the next 17 days. Wake up early in the morning, take a coffee and go out to the deck. The first image of each day being a flock of great shearwaters, some pomarine skuas, terns, gulls, gannets, storm-petrels. I couldn’t be happier.

I would like to share some of the highlights of last year’ campaigns since I didn’t have the blog yet. I prospected the Mediterranean coast, the Atlantic coast, the Cantabric coast, the Gulf of Cádiz, Moroccan coast and of course the Canaries, seeing most of Iberian seabirds and meeting unforgettable people. I will be out in the sea for a few time this year, so I will try to take profit of each minute.

The history started in July 2011, at Castelló harbour. That campaign finished in Málaga, so I saw the Mediterranean species. Audouin’s gull was one of the commonest gull species. It was interesting to see some juveniles in Cabo de Gata area… maybe a breeding evidence? The Scopoli’s shearwaters were brightful, with some unexpected Cory’s in between.
Other highlights included an adult Long-tailed skua, an Eleonora’s falcon and lots of Mediterranean storm-petrels.

The next campaign was in september at Banco de Galicia, a mountain placed 120 miles off Galicia. This is a well-known good area for Band-rumped storm-petrels and I saw more than two hundreds of them among some Leach’s and Wilson’s. The fresh plumage shown by all the individuals pointed to the winter population, foraging in the area in their way back to breeding grounds. There I saw as well my first Fea’s/Desertas petrel, some White-faced storm-petrels, Long-tailed skuas, Sabine’s gull, an offshore Short-eared owl and the rest of commoner migrants. The last day, 3 hours before entering Celeiro harbour, a nice adult Roseate tern did culminate my work.

Without time to digest that sightings, I found myself again aboard, this time off Vigo and surrounding the Galician coast, heading north. The first days were promising: another roseate tern, Wilson’s storm-petrel… but when we passed Finisterre, it got even better! 2 South polar skuas and a Barolo’s shearwater… what else?

My next step was the Gulf of Cádiz. I didn’t know what to expect there… Mediterranean species, Atlantic species? The result was a nice mixture of both. I saw a Wilson’s storm-petrel and some Leach’s, but also 3 Yelkouan shearwaters and many Scopoli’s. My last 2 Sabine’s gull of the year and at least 5 great shearwaters, noting compared with the large amounts of them I had seen in the Bay of Biscay but good numbers keeping in mind they are still rarities in Andalucia.

An then… going south to the Canaries. The voyage was quite boring. Leach’s, band-rumped and white-faced storm-petrels near Banco de Dacia and la Concepción and a Green turtle off Casablanca were the best. In the Canaries, the story did not change too much, but cetaceans are always present in that waters and the sighting of 3 Killer whales in the Bocayna strait did compensate my efforts. A week after, in 2 consecutive days, a Fea’s/Desertas petrel each day were the only bird in 18 hours of census. I was lucky to take some pictures, maybe the first ones good enough for species identification in Spanish waters.

I don’t have target birds for this year, I just will be patient.





Swimming a lot for dying on the shore

“Energy in an isolated system remains constant over time”

– Law of conservation of energy, Isaac Newton.

The population of Tenerife is increasing and, as energy, it can’t disappear, just move from one place to another. When people left the middle heights, they colonized the coasts and, while pigeons were tooking profit of that, seabirds suffered the consequences. The gulls succeed in adapting to human presence and even found new sources of food such as rubbish dumps, but tubenoses were not able to do so. The Macaronesia is an extremely important breeding point for Little shearwater Puffinus baroli, Bulwer’s petrel Bulweria bulweri, Manx shearwater Puffinus puffinus and some stormpetrels such as White-faced Pelagodroma marina and Madeiran Oceanodroma castro. The destruction of their breeding  grounds is not only due to new buildings, some mammals introduced by humans are also dangerous: the rats have settled the coast and its hungry doesn’t know limits and the cats, instead of erradicating the rats, are preying on tubenoses’ chicks. However, maybe the main problem is the artifitial light. Each year, lots of chicks and some adults die disorientated when trying to leave the nest or even during migration. They fall into the streets, always under a strong focus of light. Some others can be rescued thanks to the help of sensible people.

More or less one thousand Cory’s shearwater and 35 Bulwer’s petrels are found grounded each year in Tenerife. The Barolo’s shearwater deserves special atention since it’s one of my favourite birds and maybe one of the more threatened species of the island. The graphic below is made out of data from Rodríguez & Rodríguez, Ibis 2009, 151, 299-310. It shows the distribution of shearwaters found per year from 1998 to 2006. The situation is quite dramatic and some measures must be taken the sooner the better.

I had never seen Barolo’s shearwater from the shore until last saturday, when I saw 4 of them. The following days, I’ve seen 2 more Barolo’s and 8 Manx. What will I see tomorrow?
