SAKER FALCON. NEW SPECIES FOR EXTREMADURA

 
Saker Falcon (Falco cherrug). Piros, a juvenile female born in Hungary and photographed in Palencia by Juan Sagardía (photo taken from his personal blog). 

The news is not exactly hot off the press but the Rarities Committee has just confirmed the presence of a Saker Falcon (Falco cherrug) in Extremadura in 2009, the second record ever for Spain, after the first in Cádiz back in 10.04.02, and the first ever for Extremadura. The curious fact in this particular case is that no one has knowingly seen this satellite-monitored individual in Extremadura territory: a young female called "Piros" tagged with a satellite transmitter on 03.06.09 in Hungary. Piros set off on her juvenile-dispersal journey on 25.07.09, passing through Croatia, Slovenia and, Italy to the south of the Alps (27.07.09) and the south coast of France. It entered Spain on 30.07.09 via Girona, then crossing Lleida, Tarragona, Zaragoza, Navarre and Burgos. It then settled down for a month and a half in Tierra de Campos (Palencia, Valladolid and Zamora) until mid September, barring a brief foray into Portugal (districts of Guarda and Castelo Branco) from 30 to 31.08.09. The following map, taken from the Rare Birds in Spain Blog, traces its movements within the Iberian Peninsula.


According to the detailed info of the website www.sakerlife.mme.hu its brief passage through Extremadura broke down as follows:
- 14.09.09. 10:00-12:00 hours, Palencia. 13:00-18:00 hours, near Puerto de Béjar (Salamanca). 19:00 hours, centre of Badajoz, where it spent the night.
- 15.09.09. 07:00 hours, still in the centre of Badajoz. 08:00-12:00 hours, moved southwards. 13:00-18:00 hours, north of Seville. 19:00 hours, Doñana.
- 16.09.09 and 17.09.09. Still in Doñana.
- 18.09.09, reached Cádiz. From 19 to 20.09.09 it crossed the Straits of Gibraltar and continued through Morocco, Western Sahara and Mauritania, where it was found dead, from unknown causes, shortly after 24.09.09.


The Saker Falcon is an open-country raptor whose range spreads from central Europe to China. Europe hosts a very threatened population, closely monitored since 2006. Up to 2010 47 were tagged (43 juveniles and 4 adults) with satellite transmitters. This research has shown that the adults stay put while the juveniles make dispersal journeys of varied length. Most stick to central Europe and a sizeable share shift eastwards to the Caucasus and Belarus, and southwards to Italy and above all Sicily. Only four birds reached Africa, one of them (Piros) passing through the Iberian Peninsula. Later on, another bird in 2011 moved to the west of France, brushing the Spanish Pyrenees but without actually crossing to the Spanish side.

Birding Independently

Finally, the day has arrived. Max has his P's! No more restrictive parental driving, we are free birdwatchers! A celebratory trip was needed, though my parents refused to let us drive all the way to Botany Bay, so we had to stick with a Northern Beaches run.

I'd been up until 3:30 the night before, but I managed to rouse myself at 5:30 in the morning to meet Max out the front of my house. 40 minutes later we arrived at the Chiltern Trail, which was a bit brisk and windy to say the least. While the walk down the trail was relatively slow, the walk back provided some good birds brought out by some welcome sunshine, including Scarlet, Brown-headed, New Holland, White-cheeked, Yellow-faced, Yellow-tufted, Lewin's and White-eared Honeyeaters, plus Eastern Spinebill, Little Wattlebird and Noisy Friarbird - which was just about all of the regular Northern Beaches honeyeaters save two. A Bar-shouldered Dove back near the entrance completed our walk.

Next stop, Warriewood Wetlands, and almost as soon as stepping out of the car we were greeted by a pair of Powerful Owls, sitting in exactly the same spot (within a metre) of where we saw them late last year. 3 Varied Sittellas were seen briefly by Max while I was off in the bushes doing my best Lewin's Rail impersonation. Scarlet Honeyeaters were everywhere, and so were the lorikeets. Musk and Rainbow proved plentiful, but we couldn't get eyes on even one Scaly-breasted, even though we could hear them calling.

Pair of Powerful Owls and an unlucky Ring-tailed Possum

Across the road, the main wetlands were a little emptier than normal, but a high flying Grey Goshawk, an unseen Little Grassbird, and a Darter doing a very convincing Black Bittern impersonation helped break the monotony of hybrid Pacific Black Ducks x Mallards.

Not a Black Bittern, but a Darter... Damn

Over to Narabeen, where the resident Ospreys showed nicely for Max, as did Great, Intermediate, and 12 Cattle Egrets. More impressive however, was the group of 4 COMPLETELY PURE MALLARDS! Finding even one pure Mallard in Australia is a near impossible task, and to find 4 at once is essentially a miracle!

The miracle - ignore the dodgy bird second from the top

Nearby Deep Creek failed to give up it's Brush Bronzewings, but a pair of Rose Robins was a great way to brighten our spirits. A Dee Why sea-watch proved unsuccessful with only a few Gannets, but a very confiding Peregrine Falcon gave us both the best views we've had of this species.

Dee Why Lagoon had recently been emptied, so we decided to pay it a visit - which was a wise decision. Not only did we spot a Caspian Tern roosting with the Silver Gulls, but a Little Egret also surprised us with it's presence - a very good bird to see in Sydney. Long Reef was last, and with most of the waders gone for the winter, the best birds were Double-banded Plovers, 2 out of place Cattle Egrets, Sooty Oystercatchers and a flagged Red-necked Stint (banded in Bohai Bay, China, in 2009).

And so, our first day of independence ended, with a respectable species tally, some great birds, and no car crashes! All in all, a success.

TAGGED AND RINGED GRIFFON VULTURES SEEN IN EXTREMADURA

More and more tagged and/or ringed Griffon Vultures (Gyps fulvus) are now turning up in Extremadura. This species is marked in two ways: wing tags and colour rings, both with alphanumeric codes. As with other bird species the local group SEO-Cáceres has begun to record observations of tagged/ringed birds seen in Extremadura. In most bird species the number of birds is too low to be representative. This is not the case of the Griffon Vulture, which has by now produced enough observations to make a provisional analysis of the sightings.

Griffon Vulture (Gyps fulvus), a 4th year bird ringed at the Wildlife Refuge Centre of Burgos on 12.11.07 and photographed in Serrejón, Monfragüe, on 10.08.10 by José Luis Rivero/Objetivo Verde

Griffon Vulture (Gyps fulvus), a 4th year male tagged in Carcastillo, Navarre, on 09.11.11 and observed at Salto del Gitano, Monfragüe, on 21.02.12 by Javier Prieta and Sergio Mayordomo. 

The culled information now adds up to 49 different birds seen between 2008 and 2011. In some cases the information is partial: for eight birds the ringing site is unknown and for another twelve the age. The mode case is the observation of each individual once or several times in the same site in a single year. The longest stay was 2.5 months; two birds were seen two years on the trot; and four birds were seen in two different sites within the region (three in Monfragüe and Canchos de Ramiro and one in Monfragüe and Las Hurdes). Most records have come from Monfragüe (41 birds, 84%), with some records from Canchos de Ramiro (5), Hornachos (3), Las Hurdes (2), La Vera (1) and Valle del Jerte (1). Monfragüe's majority share of the sightings is due to the fact that it hosts the biggest regional population of Griffon Vulture (about 800 pairs in 2008) and is also the site most visited by birdwatchers. Griffon Vultures (Gyps fulvus) and Cinereous Vultures (Aegypius monachus).

4th year bird tagged in Alcoy, Alicante, on 18.10.06; seen in Barcelona on 01.07.07 and photographed at Mirabel, Monfragüe, Cáceres, on 05.02.09 by José Luis Rivero/Objetivo Verde

Origin of tagged vultures. In Extremadura tagged birds have been seen from two countries: 47 from Spain (yellow tags) and two from Portugal (green tags). White tagged birds from France have also been seen but without being able to read the code. The Spanish birds came from 13 different provinces, mainly from the northeast, pride of place going to Navarre with 11 birds. Fourteen of the birds came from wildlife refuge centres, including all the birds from Burgos, Cáceres, Andalucía and Portugal. Another three birds came from a reintroduction scheme in Alicante and the rest from diverse wing-tag monitoring programmes from Castellón, Aragón, Basque Country and Navarre.


Age of tagged/ringed vultures. Expressed in calendar years, i.e., the year of birth is the first calendar year and another year is added on each 1st of January thereafter. Thus, a bird born in 2008 would be in its fifth calendar year by 2012. Few birds were tagged as chicks in the nest, so the ageing is based on plumage; it is therefore guesswork in some cases. The graph therefore shows the certain ages in red and a minimum known age in blue. Birds aged two to four are the most commonly observed age range; there are no records of birds in their first calendar year. Observations fall away after the fifth year. As for adults, only two birds from the Los Hornos Wildlife Refuge Centre (Sierra de Fuentes, Cáceres) have been proven to be breeders, hence possibly born in Extremadura.


Phenology of the tagged/ringed vultures. Observation effort is uneven throughout the year so this introduces a bias in the results. The peaks in spring and troughs in summer may be as much a reflection of the number of birdwatchers visiting Monfragüe as the movements of immature Griffon Vultures around the Iberian Peninsula. The back histories of the birds seen often have gaps, indicating only the ringing dates and not the monitoring thereafter. Nonetheless, some of the more complete back histories do seem to show a displacement of birds from northeast Iberia to Extremadura in winter-spring, with a return flow to the northeast, even to the French Pyrenees, in summer-autumn. Publication of the results of these tagging and ringing projects will no doubt clear up these matters and other questions.


Acknowledgements: our thanks go to all observers who have taken the trouble to read the ring codes and wing tags and then pass on the information. To Javier Briz for compiling the readings and finding out the back histories. To everyone who has helped to fill in these back histories, especially Álvaro Camiña and Maquia Ambiental.

Very Quiet

I spent 4 Hours at the Reedbed site this morning and only ringed 2 Blackbirds very Quite with no sight or sound of Sedge Warblers having returned yet. I packed up and headed off to another site we have permission to ring at on the coast. Not many days when you can put a mist net up here with out the wind blowing. I have been placing corn down for Yellowhammer at this site as they have been ringed here before. I was hoping to Whoosh net here because of the wind.
Yesterday i went for a look and saw there were 4 Yellowhammers on the site, 2 Pairs. The wind was to strong to try and place a net and the birds were no where near the seed and quite happy to sit up on the Gorse and let me get a few shots.
So today a net went up and a cracking Adult male was ringed.
Yellowhammers on the isle of Man are very few and far between in the Manx bird Atlas it gives the population as between 122 >146.
I do not think it is any where near that now but hopefully with a feeding station now set up and birds about we will be able to monitor the numbers.

Spring not yet sprung

If the BTO tracked Cuckoos are anything to go by, it's going to be a while before any good number of migrants arrive in Norfolk. This time last year I was out looking at lots of migrants (Whitethroat, Lesser Whitethroat, Gropper, Yellow Wagtail, Cuckoo, hirundines, etc.) but it looks like the large area of low pressure covering much of central Europe is holding back many of the migrants. The diversity of summer migrants at Waxham today hadn't really changed since last weekend. A few Barn Swallows, good numbers of Willow Warblers and a single Wheatear was about it. The highlight of the day was 2 Short-eared Owls moving through the dunes (presumably fresh in off the sea), which paused for a while to rest in the Marram Grass before being harassed by Magpies and moving off south.
A party of 7 Common Cranes also put in a good overhead show at Horsey Gap.

A Taste of Fijian Birds

With my Grandma’s significant 70 milestone this year, the whole family headed over to Fiji, where she grew up, for a reunion. I was grateful at the privilege to be going to such a great place to get a spot of birding done.

Within a few seconds of the plane’s wheels touching the tarmac, a nicely breeding plumaged Pacific Golden Plover was seen on the grass. The drive through Nadi to Denaru reminded us of the devastating floods the week before – furniture strewn everywhere to dry out, huge puddles, broken bridges. Denaru was quite empty (like our flight in), as many people had cancelled their trips. Luckily, the things we were doing had remained unaltered, and life seemed to be progressing almost as normal.

At Denaru Port, I quickly got onto a mixed flock of Fiji Parrotfinches and Red Avadavats. After an early dinner, the port car-park yielded two Polynesian Trillers (the only ones for the whole trip surprisingly), Pacific Swallows, and a pair a Fiji Woodswallows.


The next morning, the Yasawa Flyer was to take us out to Octopus Resort on Waya Island, where we would spend the next three days. On top of a yacht mast in the marina, a bird of prey took off. To my surprise, it was a Peregrine Falcon, a very rare bird in Fiji, the field guide says there are only 40!
I spent the next 3 hours looking for seabirds, with Black Noddies, Black-naped Terns, Lesser Frigatebirds (40 of them! Not normally in the Yasawa Islands, probably blown in by the previous week’s bad weather), Brown Boobies, and some frustratingly bad views of what were probably Bridled Terns.

This wasn't taken on the boat, but when I was on Waya. What a sight it was!

The next 4 days were at Octopus Resort. In between snorkelling and relaxing, I managed Sulphur-breasted Myzomela, Collared Kingfisher, Vanikoro Flycatcher, as well as the ever-present Red-vented Bulbuls, Silvereyes and White-rumped Swiftlets.

On the third day, my dad and I joined a hike up to one of the mountains in the centre of the island. Now, the field guide says there are Golden Doves on Waya, but I didn’t find any evidence of them… Anyhow, the hike was extremely tiring, lots of it a hard slog, but the end was worth it. Panoramic views of the Pacific Ocean, dotted with various islands, and to top it off, a couple of Fiji Woodswallows hawking around at eye level against a backdrop of coral reefs! The places the birdwatching brings you are just amazing!

Two days later, after a boat trip back to Viti Levu and a late night taxi ride, I found myself waking up on the Coral Coast, at Korotogo near Sigatoka. Within the next 3 days, most of the family arrived and we had a wonderful time.

But that’s enough of that. The birds.

By far the standout of our accommodation at Tubaluka was the flowering tree 20 metres from our cabin. Collared Lory galore! What beautiful parrots they are. A large flock of Fiji Parrotfinches frequented the grass, and I saw them regularly.

On the second day, I went to check out the nearby Kula Eco Park, Fiji’s only wildlife park. As well as having some impressive native fauna and flora on display, it does some impressive conservation work (only here and at Taronga Zoo can you see Fijian Crested Iguanas being bred up for release), and with the cages and walkways set up in a nice rainforest, there are also some nice birds about. After a bit of searching, I located a small feeding flock, consisting of three Fiji Bush Warblers and a single Slaty Monarch. My grandma, being the kind and loving person that she is, introduced me to the manager, and so we arranged an early morning trip for me to look for Golden Doves in the park’s forest.

Take my word for it, it's a Fiji Bush Warbler

The next morning at 6:30, I met Pradeep, a great guy who has been working at the park for 9 years. He collects food from the rainforest, and regularly sees the resident Golden Doves there. 2 hours later, after a lot of slogging through rainforest, trekking up muddy banks and splashing through creeks, we had nothing to show for our efforts (and I literally mean not one bird was seen, of any species). Then, we found ourselves back at the gate (I had to leave for a family outing in 30 minutes), so I was ready to admit defeat, when Pradeep thought we should check out some bushes near the fence line behind the chook house, where he said the doves often feed. Sure enough, we had just turned our heads to look in that direction when a beautiful female Golden Dove flew up onto a branch. We crept round and had a look at the bird from less than two metres away at eye level as it fed on some small berries. Also feeding in these bushes was a flock of 7 White-throated/Metallic Pigeons (one sat very nicely in the sun), and it took me a while to figure out what a Reba was (apparently there was one sitting in the tree above us, and I eventually spotted the young Fiji Goshawk perched there). Sod’s law at its finest!

The family outing to Suva followed, and after a day of driving along the coral coast and being shown where grandma grew up, we headed for a very quick trip to Colo-I-Suva Forest Park (pronounced tholo-ee-suva). Now, we had originally been going to stay here for one night, but the warnings of rape and muggings on the internet had put us off. Let me tell anyone reading this, that there is nothing wrong with the park. We talked to the manager of Raintree Lodge, and he said that it happened once 15 years ago and they can’t get rid of it from the internet. Moral of the story – make sure you spend one night at Colo-I-Suva, not one hour at noon!

That said, I stilled managed some great birds – Masked Shining Parrots flew past, a pair of Pacific Robins sat quietly, a pair of Azure-crested Flycatchers flitted about, and the ever-present hoot of Barking Pigeons eventually allowed me to see a few birds well (after a fair bit of stress!), and a female Fiji Whistler regarded me quizzically. I heard a few more species, including a male Golden Dove and a few Giant Honeyeaters, but time was short and I had to be satisfied with what I had.
Blurry Male Pacific Robin

The next few days were taken up by games, food, snorkelling, and relaxation. Also I got the dreaded travel bug… ;D

In summary, 22 lifers, of which 10 were endemic to Fiji. The whole Pacific Ocean is an amazing place in itself, and the birds it contains are just beautiful. I have made it my resolve to see that male Golden Dove one day, so I will be back (hopefully seeing everything else while I’m at it)!!!

Holy Grail: The male Golden Dove eluded me in the wild... for now
