Bird of the Week – Bonelli’s Eagle

Bonelli's Eagle (Aquila fasciata) by Ian

This is the last in this series of raptor photos from the Pyrenees: Bonelli’s Eagle taken at another feeding station managed by Birding in Spain. Like last week’s Northern Goshawk feral pigeons from a local council culling programme are used to attract the eagles. It’s brown and white plumage reminded me rather of the similarly sized Osprey particular that of the male, first photo, which is paler than the female. In size it has a length of up to 73cm/28in, a wingspan to 180cm/71in and weights up to 2.4kg/5.3lbs. That makes it much smaller than most of the other Aquila eagles, such as the Golden and Wedge-tailed but larger than the Little Eagle of Australia.

There the resemblance to ospreys ends, as Bonelli’s Eagle is found in hilly or mountainous country in warm regions and eats mammals and birds – in Spain it eats mainly rabbits and partridges. The second photo shows the view from the hide. The stone wall on the left is where the food is tied in place, as is done with the goshawks to prevent them from carrying the food away. The bird arrived quite promptly after set up: you can see in the first photo that the reflection of the sun in its eye is just above the horizon.

The third photo is another one of the male with the remains of a pigeon. On the back just below the neck a white spot is visible – this is a diagnostic feature of adult Bonelli’s Eagles and fairly conspicuous in flight though the birds arrived and departed so quickly from the rocky ridge in front of the hide that I didn’t get any decent flight shots.

They were fast eaters too. The fourth photo was taken 25 minutes after the third: very little of the pigeon remains and the crop of the bird is quite full. The adult goshawk also took about half an hour to demolish a pigeon, but the immature goshawk took the best part of two hours and remained long after the adult had left. Despatching prey at speed would appear to be a skill that takes raptors a bit of practice. Both these photos show the feathered legs or ‘boots’, characteristic of ‘true’ eagles. They’re not exclusive to eagles though. The goshawks had impressive trousers too as do some falcons such as the Brown Falcon of Australia.

Bonelli's Eagle (Aquila fasciata) by Ian

Once fed, the male seemed more aware of what was going on around it and in the fifth photo is peering at the hide, presumably in response to the sound of the camera shutter.

Meanwhile, the female, sixth and seventh photos, was getting stuck into the other pigeon. She was a fine-looking bird too, larger than the male, with hazel eyes and identifiable by much stronger streaks on the breast. The female had much darker trousers, seventh photo, but I don’t know whether that’s generally the case or peculiar to this bird.

Bonelli's Eagle (Aquila fasciata) by Ian Female

Bonelli’s Eagle is widely but sparsely distributed through southern Europe, northern Africa, parts of the Middle East, South and Southeastern Asia as far east as Timor. The European population is about 900 pairs, of which about 700 are in Spain. They are sedentary, keeping to their large home ranges throughout the year. Satellite tracking in Spain has shown an average home range of 200sq km/77sq miles with a core range of about 45sq km/17 sq miles.

Bonelli's Eagle (Aquila fasciata) by Ian Female

The generic name ‘fasciata’ comes from the Latin fascia meaning stripe, band or sash. It’s usually used in birds to refer to horizontal bands or barring but maybe Veillot, the taxonomist responsible, was referring to the barring on the ‘trousers’ rather than the streaks on the breast. Veillot, Jean Pierre that is, was an important French avian taxonomist, 1748-1831, who extended the three-level Linnaean classification of order-genus-species into order-tribe-family-genus-species in his Analyse d’une nouvelle Ornithologie Elémentaire (1816). Franco Andrea Bonelli was, unsurprisingly, an Italian ornithologist 1784-1830 and discovered both this eagle and Bonelli’s Warbler in 1815. He worked at the Natural History Museum in Paris 1810-11 before returning to Italy to take up the position of Professor of Zoology at the University of Turin. Interestingly, he published his main works in French.

Lee’s Addition:

They are passed away as the swift ships: as the eagle that hasteth to the prey. (Job 9:26 KJV)

Their horses also are swifter than the leopards, and are more fierce than the evening wolves: and their horsemen shall spread themselves, and their horsemen shall come from far; they shall fly as the eagle that hasteth to eat. (Habakkuk 1:8 KJV)

What an amazing set of photos of this magnificent Eagle. Thanks again, Ian, for sharing these fantastic glimpses of the Bonelli’s Eagle. Pretty fast eaters, it appears.

This Eagle is a member of the Accipitridae – Kites, Hawks and Eagles Family and a Bird of the Bible also. Eagles are mentioned over thirty times in the Bible, plus they are included in the various “birds of prey” verses.

Ian’s Bird of the Week – Northern Goshawk

Northern Goshawk (Accipiter gentilis) by IanIan’s Bird of the Week – Northern Goshawk  by Ian Montgomery

Newsletter ~ 11/17/14

I got so absorbed in recounting my experiences in Catalonia, that I forgot to mention that I’ve been home in North Queensland for several weeks.

The piece about the effects of diclofenac prompted some interesting responses. It was pointed out that it causes kidney not liver failure in vultures, my apologies, and that a safe and effective substitute in both humans and livestock is the anti-inflammatory meloxicam. It’s sold here as Mobic, which I take sometimes when I wayward spinal disc misbehaves. I also received a link to this article by the Vulture Conservation Foundation which has managed to get the EU to do an investigation into the effects of diclofenac: http://www.4vultures.org/our-work/campaigning-to-ban-diclofenac-in-europe/.

On the second day of our stay in raptor country in the Pyrenees with Birding in Spain we – my sister Gillian joined me for this one – were taken by Steve West to a hide at a Northern Goshawk feeding station before sunrise – goshawks are earlier risers than I am normally and are shy. Here the goshawks are fed regularly on chicken carcasses and fresh pigeon, the product of a culling programme by the local council. It was a misty, chilly, gloomy morning – sunrise was the time of day rather than an event – and the first bird to arrive, the adult female in photos 1 and 2, was barely visible. The second photo was taken at 1/3 of a second exposure at 1600 ISO and my tripod, inconvenient for travel, proved its worth yet again.

Adult females are more strongly barred and much larger than males (to protect succulent-looking nestlings). This one is partially spreading its wings and tail near the food in a posture that looks like a rudimentary ‘mantling’ display. This is usually used by hawks as a threat display to discourage other ones from interfering with their prey. In this case, I suspect it was signalling the presence of food to the juvenile goshawk, third photo, who appeared shortly afterwards. First year juvenile Northern Goshawks are brown with buff, almost cinnamon underparts and are streaked rather than barred. Similar juvenile plumages occur in other close relatives in the Accipiter genus such as the Brown Goshawk (A. fasciatus) and Collared Sparrowhawk (A. cirrocephalus), both common in Australia; see http://www.birdway.com.au/accipitridae/brown_goshawk/source/brown_goshawk_32464.htm and http://www.birdway.com.au/accipitridae/collared_sparrowhawk/source/collared_sparrowhawk_62859.htm for examples of their juvenile plumage. Note, incidentally the ‘beetle-brow’ characteristic also of the Brown Goshawk that gives the larger goshawks their fierce expression.

Northern Goshawk (Accipiter gentilis) by IanThe adult female moved aside and let the juvenile have the pigeon prey and the juvenile then adopted the possessive mantling display with spread wings and tail and fluffed-out feathers of the mantle, just below the neck.

Mother, I presume, tackled a piece of chicken carcass and carried it down onto the ground closer to the hide, but partially obscured by dried grass and other vegetation.

Northern Goshawk (Accipiter gentilis) by IanThe sixth photo shows the juvenile somewhat later with the remains of the pigeon. This was a very large bird too, as you can perhaps judge from its appearance, so I concluded that it was female too. ‘Huge’ is perhaps a better description, as the Northern Goshawk is easily the world’s largest of the nearly 50 or so species of Accipiter – (typical hawks comprising larger goshawks and smaller sparrowhawks, though ‘hawk’ is also used in North America to name other raptors such as those in the genus Buteo aka ‘Buzzard’ in British English). The female is up to 65cm/26in in length with a wingspan of up to 120cm/47in and a weight of up to 2.0kg/4.5lb, comparable in size with many Buzzards. All the Accipiter hawks tackle relatively large prey, mainly birds and some mammals. They hunt by surprise and pursuit and have rounded wings, long tails and fast reflexes for great manoeuvrability in forests. I suspect that Linnaeus used the specific moniker ‘gentilis’ in the sense of ‘noble’ rather than ‘gentle’. ‘Goshawk’ comes from the Old English ‘göshafoc’ meaning goose hawk, no mere chicken hawk.

Northern Goshawk (Accipiter gentilis) by IanThis was another species that had aroused my interest in my field guide as an Irish teenager, and hadn’t seen before this trip. It’s a very rare vagrant in Ireland and was then only an occasional breeder in Britain though widespread if uncommon elsewhere in temperate regions of the Northern Hemisphere. Since then it has become re-established in Britain with a breeding population of 300-400 pairs.

Northern Goshawk (Accipiter gentilis) by IanBoth birds lightened their load, as many raptors do, before taking flight, as the juvenile is doing in the seventh photo. There’s a photo on the website of the female doing the same thing: http://www.birdway.com.au/accipitridae/northern_goshawk/source/northern_goshawk_161882.htm. Even nobles have to perform basic functions: don’t stand behind or below a well-fed raptor :-).

Lee’s Addition:

“And these you shall regard as an abomination among the birds; they shall not be eaten, they are an abomination: the eagle, the vulture, the buzzard, the kite, and the falcon after its kind; every raven after its kind, the ostrich, the short-eared owl, the sea gull, and the hawk after its kind; (Leviticus 11:13-16 NKJV)

What a beautiful family of birds. Ian always has such great photos and adventures to share with us. Thanks, Ian.

Ian’s Bird of the Week – Cinerous/Eurasian Vulture

Ian’s Bird of the Week – Cinereous/Eurasian Vulture ~ by Ian Montgomery

Newsletter ~ 10-28-14

This is 2 of 3 in a series on Eurasian vultures photographed during my recent spell in a bird hide at a vulture feeding station in Boumort National Reserve in the Pyrenees in Catalonia not far southwest of Andorra. The first of the series was on the Griffon Vulture (see http://www.birdway.com.au/accipitridae/griffon_vulture/index.htm where I’ve put a dozen photos), this one is on the second species in the feeding order, the Cinereous or Eurasian Black Vulture. Here, incidentally, is the view taken from the hide – with my phone! – shortly after the rangers had left and the first one hundred or so Griffons, and a few Common Ravens, were in the process of arriving.

Because of the wide-angled nature of phone cameras, the vultures appeared in real-life to be much closer, close enough for one bird to almost fill the frame of a full-size (35mm sensor) DSLR with a 500mm lens. The second photo shows the luxurious and well-appointed hide (I mentioned the toilet last week) with my camera and 500mm lens set up on my tripod and my binoculars and smaller 100-400mm lens at the ready. I was on my own for the whole day, so I could move freely between the three viewing openings. The one in the middle overlooked the feeding site (above), the one on the left was good for photographing landing vultures using the 100-400mm lens, while the one on the right overlooked a pond, used by the vultures on a hot day. It was cool and overcast when I was there and rained a bit, so the only vulture I saw at the pond was a Griffon having a drink.

It’s impossible to travel lightly with good gear for wildlife photography – the tripod along required taking a larger suitcase than both I and airlines prefer – but on that day in the hide and on an earlier occasion when I was photographing Crab Plovers in Dubai, I was really glad to have to have brought the necessary stuff with me. Anyway, back to the Cinereous Vulture. In the days when birders weren’t inter-continental travellers, it was called the Black Vulture until it was realised that this risked confusion with the completely unrelated Black Vulture of Central and South America and the ‘Eurasian’ label was applied. Now BirdLIfe International call it the Cinereous Vulture, ‘cinereous’ meaning ‘ashy’, like the adult in the third photo, which certainly looks as it has been rummaging around in the remains of a camp fire.

Cinereous Vulture (Aegypius monachus) by IanThis bird shows the typical vulture ruff, with the cowl-like adornment characteristic of this species. The specific name monachus means ‘hooded’ but the common name Hooded Vulture is already used for another somewhat similar, sub-Saharan species, Necrosyrtes monachus. Juvenile birds are much darker, dark chocolate really, like the slightly scruffy one in the fourth photo. Some field guides say that juvenile birds have pink facial skin – like this one – but I couldn’t find a clear correlation between age and skin colour: some adults had mainly blue, others more pink skin, which made me wonder whether it was influenced by gender. All the Cinereous Vultures here had metallic identifying rings/bands and some, particularly juveniles had coloured bands as well. This is because the species has recently been re-introduced to this area from central Spain, is now breeding and the population is being studied thoroughly.

Cinereous Vulture (Aegypius monachus) by IanThe Cinereous Vultures took their time and started arrived at the feeding site about an hour after the Griffons. As you can guess from the relative amounts of plumage on the heads and necks of the two species, they have quite different feeding habits. Griffons clearly don’t mind getting up to their elbows in it, so to speak, but the Cinereous Vultures prefer to wait until the dirty work has been done and then pick up their favourite morsels. Their reluctance to get involved in the initial scrum has nothing to do with size or dominance, the Cinereous Vultures are as large or larger than the Griffons and are quite dominant. The bird in the fifth photo has a feeding juvenile Griffon it its sights and is advancing threateningly in a manner that was wonderful to watch, head down, wings spread and ruff and cowl feathers erect with a bouncing walk. The result was something like the witches from Macbeth combined with the loping gait of a kangaroo.

Cinereous Vulture (Aegypius monachus) by IanIt might look funny to us, but it was very effective and the Griffons, unamused, backed off, like the frustrated-looking one in the sixth photo. Cinereous Vultures have strong bills and can tackle, tendons, muscles and, by the look of the one in this photo, skulls. Maybe cervelles are on the menu. (I once understood cervelles d’agneau on a Parisian menu to be something to do with lamb and was slightly taken aback when brains, rather than a chop, appeared in front of me.)

Cinereous Vulture (Aegypius monachus) by IanThe Cinereous Vultures were the least volatile of the three species and once having landed, hung around for hours. I didn’t get photos of any in flight, but I didn’t find them easy to separate from the Griffons in flight as they’re silhouettes are rather similar. The Griffons kept landing and talking off and were better targets and more numerous. In total, there may have been 10-20 Cinereous Vultures. Their reintroduction here is part of a more general EU conservation and anti-poisoning program that has seen the population in Spain recover from 290 pairs in 1984 to perhaps 2500 now and they have been reintroduced into southern France. The conservation news isn’t all good, though to say the least, and I’ll return to this topic in the third in this series.

Cinereous Vulture (Aegypius monachus) by IanPart of the research effort at Boumort is the study of the movements of these vultures. Adults are thought to be mainly sedentary in Europe, though partially migratory in Asia, where it also occurs. Some banded Spanish birds have turned up in sub-Saharan Africa. Some birds have been fitted with GPS units, and you can see one, complete with solar cell on the back of the juvenile in the last photo.

I mentioned the unrelated Black Vulture of the Americas, one of the New World Vultures. These include the Turkey Vulture, familiar in North America, the Condors and a couple of other species places in a separate family, the Cathartidae http://www.birdway.com.au/cathartidae/index.htm. In fact Birdlife International put them in their own order, the Cathartiformes, indicating that they arose completely independently. The Old World Vultures, on the other hand, are close related to hawks, eagles, etc. and are placed in the same family Acciptridae in the order Acciptriformes. I must admit I was struck by the eagle-like facial appearance of these birds and it appears that the Old World Vultures have developed twice within the Acciptridae. Most belong to a group of typical Old World vultures that includes the Griffon and the Cinereous. Three, however, form a separate group placed taxonomically near the Serpent Eagles. One of these is the subject of the next edition. The vultures kept me waiting in suspense for crowning moment, and I’m trying to make you share the anticipation: I have something really special for the next bird of the week!

Greetings
Ian

Lee’s Addition:

But these are the ones that you shall not eat: the eagle, the bearded vulture, the black vulture, (Deuteronomy 14:12 ESV)

And when birds of prey came down on the carcasses, Abram drove them away. (Genesis 15:11 ESV)

What a blind! When Ian go out photographing, he goes all the way. I always enjoy his adventures. Vultures are a favorite of mine, but the Lord created them and gave them a job to do. What would the world look like if they didn’t come down and clear up carcasses.

Again, these Vultures are members of the Accipitridae – Kites, Hawks and Eagles Family. I like that fifth photo with that pose of his. Especially with Halloween just around the corner.

Thought you might enjoy a video of the birds that make Spain their home. Paul wanted to journey to Spain. These type of birds would have greeted him. Also, my good friends, Tim and Pam, are missionaries there.

whenever I journey to Spain, I shall come to you. For I hope to see you on my journey, and to be helped on my way there by you, if first I may enjoy your company for a while….  Therefore, when I have performed this and have sealed to them this fruit, I shall go by way of you to Spain.  (Romans 15:24,28 NKJV)

Eurasian Hoopoe (Upupa epops) by Ian

Eurasian Hoopoe (Upupa epops) by Ian

I have enjoyed getting to know the Tim and Pam Darling, our missionaries, while they have been in transition from the field of Venezuela to Spain. We have all been praying for them to get their Resident Visas so they can get on over to Spain to start their new ministry. They now have the Visas in hand, which is a great answer to prayer. They are busy getting packed up and will go to Spain around the 10th of November.

Spanish Sparrow (Passer hispaniolensis) by Nikhil Devasar

Spanish Sparrow (Passer hispaniolensis) by Nikhil Devasar

This blog is in honor of their friendship and to help them get to know the birds they may encounter in Spain. Thanks, Tim and Pam, for your friendship and our prayers will follow you as you travel and reach those in Spain for our Lord Jesus Christ.

Of course the Sparrows will be over there. The House Sparrow, Spanish Sparrow, Eurasian Tree Sparrow, Rock Sparrow and the White-throated Sparrows will help you to remember

Even the sparrow finds a home, and the swallow a nest for herself, where she may lay her young, at your altars, O LORD of hosts, my King and my God. Blessed are those who dwell in your house, ever singing your praise! Selah (Psalms 84:3-4 ESV)

Along with them you will get to meet the Eurasian Hoopoe. A favorite of mine. There will be Swifts – Common, White-rumped, Little, Pallid and Plain Swifts. Also the Swallows – Red-rumped and the Barn.

Yea, the stork in the heaven knoweth her appointed times; and the turtle(dove) and the crane and the swallow observe the time of their coming; but my people know not the judgment of the LORD. (Jeremiah 8:7 KJV)

Lots of Doves and Pigeons to be on the lookout for – Rock Dove (pigeon), Eurasian Collared-Dove, Oriental Turtle-Dove, Laughing Dove, European Turtle-Dove, Bolle’s Pigeon, Laurel Pigeon and a Stock Pigeon. Only found the Common Crane listed there.

There are 9 kinds of Owls, 10 in Falcon family, 3 Kites, 3 Bitterns, 2 Cormorants, 4 Herons, 3 Storks, 2 Hawks, 2 Lapwings, the Osprey, 3 Partridges, 2 Quails and the Bobwhite, and 4 Swans.

There is the Common Raven and you know what the Word says about the Ravens.

Consider the ravens: for they neither sow nor reap; which neither have storehouse nor barn; and God feedeth them: how much more are ye better than the fowls? (Luke 12:24 KJV)

Tawny Eagle by Africaddict

Tawny Eagle by Africaddict

Saved the Eagles for last, not because they are bad, but because of the promises that use them as examples. In Spain they have the Adalbert’s, Golden, Greater Spotted, Imperial, Lesser Spotted, Tawny, Short-toed Snake-Eagle, White-tailed Eagle, Bonelli’s Eagle and the Booted Eagles.

Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven. (Proverbs 23:5 KJV)

The Darling’s are definitely not going to Spain to obtain earthly gains, but to gain heavenly rewards.

But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. (Isaiah 40:31 KJV)

Tim and Pam, our collective prayers will go with you.

(Updated 8-04-12) We have had the privilege of spending some time with Tim and Pam for the last few weeks while they have been on a short furlough. Her parents belong to our church and live in the area. I have tried to encourage them to send me some photos of the birds in Spain. Stay tuned, maybe we can have another update.)
