Blog Tour - Crossley Raptors UK - Free Book Draw

Yes this is it folks, and if you reached here today via Princeton University Press Blog or Birdfreak.com you will know what this is all about. For regular readers of Another Bird Blog today’s post is a little different in the form of a whistle-stop on a transatlantic blog circuit organised by Princeton University Press, a tour of Internet birding and featuring Richard Crossley’s new book The Crossley ID Guide:Raptors. 

Readers will remember Richard’s Crossley’s innovative and highly successful book The Crossley Guide:Eastern Birds, reviewed here on 27th January 2011. The post became the most visited page on Another Bird Blog with more than 1200 hits to date. The book became a huge success and Richard is now following it up by joining forces with Brian Sullivan and Jerry Liguori to co-author this new volume which takes a detailed look at North American raptors.

The Crossley ID Guide:Raptors

As part of Another Bird Blog’s contribution to this circuit and further down the page there is a draw whereby two lucky people will each receive a copy of The Crossley ID Guide:Raptors. All you have to do to be in with a chance is answer a simple question. So read on but don’t skip the middle bits which may give a clue as to the answer to my question. 

This new book may be produced in the US but let’s not forget the UK and the US share not only chunks of our history and culture but also a number of birds of prey and occasional transatlantic passerine and wader vagrants.  There’s a healthy interchange of bird watchers too, with US birders heading to Europe as well as many UK birders visiting US raptor watching stations and bird observatories or taking birding holidays.

I looked through the The Crossley ID Guide: Raptors to find the species common to both nations, the familiar birds which UK birders might see over in the US, and the regular species a US birder might well see in the UK. We share species, but we often like to name them slightly differently, a whimsy of our respective ornithological systems, so I will list the species and include both name versions where appropriate, US version first followed by the UK name and then finishing with the Latin name:

• Merlin Falco columbarius
• Northern Harrier/Hen Harrier Circus cyaneus
• Rough-legged Hawk/Rough-legged Buzzard Buteo lagopus
• Peregrine Falcon Falco peregrinus                         
• Gyr Falcon Falco rusticolus 
• Northern Goshawk Accipiter gentilis 
• Osprey Pandion haliaetus 
• Golden Eagle Aquila chrysatos 

There may be several thousand miles of ocean separating the US and the UK, but there are subtle variations as well as the obvious similarities, with just a few of those detailed below.

In the tiny landmass of the UK our Merlin is the singular species of Falco columbarius. In the vast continent of the US with its huge variety of habitats the Merlin has evolved into three sub-species differentiated mainly by the darkness of their plumage. There is a dark form, the so called “black” Merlin of the Pacific Northwest, a pale “prairie” Merlin of the northern Great Plains, and the intermediate “taiga” Merlin of open forest. It’s the latter type which is equal to our familiar UK Merlin.

Following a number of variable plumages seen in the UK autumn time, there’s been discussion here about the possibility of Northern Harrier/Hen Harrier Circus cyaneus being two species, a North American one and a slighly different European/UK type. The jury, in this case the International Ornithological Committee, examined the evidence and decided not to split as the genetic differences between the two are very low in comparison to many other Eurasia/North America disjunctions.

Happily both of our Peregrine populations are in a healthier state since the ban on DDT of the early 1970s which led to a recovery in numbers. This has been supported by large-scale protection of nesting places and a reintroduction programme in the many parts of the US. In both our countries the Peregrine has reoccupied former haunts and they now breed on human artefacts in our city centres. There are three subspecies of Peregrine Falcon in the US, tundrius of the north, anatum found mainly in the Rocky Mountains, and pealei which is found in the Pacific Northwest. Peregrines introduced into the eastern and other states are of mixed races. Here in the UK our Peregrine Falcons are from the nominate (first named) race Falco peregrinus peregrinus.  

Rough-legged Hawk/Rough-legged Buzzard Buteo lagopus is but a very irregular winter visitor to the British Isles, spreading here from continental Europe, generally during times of intense cold weather and/or shortage of their lemming/mammal prey. This situation rather simplifies separating out our everyday UK Common Buzzard Buteo buteo, unlike the US landmasses where 10 species of Buteo occur, all of which feature in The Crossley ID Guide:Raptors.

The Gyr Falcon is incredibly hard to see in the UK, and just like the Rough-legged Hawk the pale Arctic falcon is a very irregular visitor to the UK mainland. As Crossley has described its status in the US, “a loner with a huge territory”, an accurate portrayal for a bird which spends much of its time hunting across the northern oceans.

In the US the Northern Goshawk is a widespread but scarce breeder of forested areas. It's a status replicated over here in the UK, whereby spotting a Goshawk makes for something of a birding Red Letter Day.

Ospreys are a common sight in in many parts of the United States, whereas in the United Kingdom the species is confined mainly to Scotland with just a small number of pairs breeding in the more remote parts of Wales and northern England. In the English counties Ospreys are a regular sight on migration during both spring and autumn periods.  

Last but not least on my list is the magnificent Golden Eagle, a species which in both the UK and the United States breeds only in the more remote northern forests and mountains. Here in the UK our Golden Eagles are confined to the inaccessible parts of Scotland and rarely venture south across the border into England. 

And now without further ado the prize draw - at last you say. There is a small, colourful  raptor featured in The Crossley ID Guide: Raptors which has occurred in the UK on less than a handful of occasions, in fact just two accepted records, so few that while it belongs on the Britsh List of birds as maintained by The British Ornithologist's Union's Records Committee (BOURC), I didn't include it in my summary of shared species above. The last occasion this raptor appeared in the UK as a vagrant was during the late 1970s, over 35 years ago. What is the species? Please post your answer as a  comment to this post before 27th March 2013. Two winners will be chosen at random, and due to logisitcs, one from the US and one from the UK. The winners will announced on Another Bird Blog on 28th March and requested to send me (in confidence) their postal address. In due course each winner will receive a copy of The Crossley ID Guide:Raptors courtesy of Princeton University Press.

As part of this two-week blog tour raptor enthusiasts are invited to join in a live Shindig video chat event on Friday 22nd March - "Raptor ID Happy Hour" from 6pm to 7pm EST at  Shindig's Raptor Event. Two of the participants are the authors themselves, Richard Crossley and Brian Sullivan - sounds like a good place to be on a Friday evening with a glass of beer close to hand.

Next stop on today's blog circuit is a trip to Radd Icenoggle in Montana USA where Radd's Blog is looking back at the Montana State recovery programme which rescued the Peregrine Falcon from the verge of extinction in that region. Following on from Radd the Magnificent Frigate Bird web site will feature Barred Owl and Cooper's Hawk and there's another chance to win copies of The Crossley ID Guide:Raptors.

Finally and before you head off to Montana with Radd, don't forget to enter today's prize draw on Another Bird Blog and then come back soon to find out the winners of the fabulous prizes.

Hawks At A Distance

Princeton University Press kindly sent a copy of Hawks At A Distance for review by Another Bird Blog, knowing that despite the UK based nature of the blog, it has followers in the North American continent.

Hawks At A Distance is a field guide for the North American bird watching fraternity, a book compiled by one Jerry Liguori, a birder and premier division hawk watcher with many years of raptor experience. Since 1984 he has conducted spring and autumn raptor migration counts at watch points such as Cape May, Sandy Hook, Derby Hill, Braddock Bay, Whitefish Point, Dinosaur Ridge, and many others. Needless to say, this superficially modest list conceals the many, many hours of sitting and studying, squinting and staring through binoculars, telescopes and cameras, a labour of love that gave birth to this, his latest book of excellence.

Hawks At A Distance

For me and many others, identifying raptors in flight is the birding challenge, especially hawks and eagles that fly at great heights. Migratory ones are even more difficult to identify as the average birder rarely gets the opportunity to study them closely or for long enough to learn their characteristics. So a concise and portable field guide that makes this identification process easier is to be welcomed as a timely addition to any bird library.

This slim guide manages to illustrate 29 species in a variety of lighting situations and settings, contains 558 colour photographs and 896 black & white images showing distant raptors at different angles of flight with all of the subtle variations of age and sex. A really useful section entitled “Shapes” at the end of the book displays the silhouettes formed by the different species of raptors from a variety of angles and at different heights.

Shapes

From my UK perspective I was particularly interested in the species which in one case cross UK and US Atlantic boundaries – Northern Harrier, then others which occur on both sides of the pond in much the same form – Northern Goshawk, Rough-legged Buzzard/Hawk, Gyr Falcon, Peregrine and Merlin. Interesting and informative then that Liguori’ s photos and narrative both show and tell us how to distinguish the three races of Merlin that occur in North America, Taiga Merlin i.e. our UK columbarius, Prairie Merlin, richardsonnii, and Black Merlin, suckleyi.

Northern Harrier

I found 42 photographs (in addition to the single beautiful photo that precedes the section) devoted to Rough-legged Buzzard/Hawk alone, that problematic bird of Birdguides and Rare Bird Alert notoriety. If only the 42 photos of the changeable hawk could be included into a new European guide, where the same pictures would surely feature next to a set of photos showing the various guises of Common Buzzard. Perhaps herein lies your next book Mr Liguori?

Rough-legged Hawk/Buzzard – Buteo lagopus

If I have one reservation about this guide it is that most if not all of the photographs used have been taken in good light and against a blue sky. This may be the norm for raptor watching in North America or even parts of the Mediterranean, but in practice in the UK at least, much raptor watching is against an overcast, grey sky. Notwithstanding this purely personal quibble I heartily recommend this book to North American raptor enthusiasts, but also to anyone with a general interest in raptors, but especially for birders planning a birding trip to North America where it will sit happily in a pocket or rucksack next to a less specific field guide.

Having praised the book I also add the caveat that it is a book very much for a niche market, for the person who is happy to sit at a watch point aiming to identify hawks from a distance, in flight, with binoculars and/or a telescope. Anyone not falling into that category will have limited use for this book and may well prefer a generalist but ultimately less detailed field guide.

Hawks At A Distance is available from Princeton University Press at $19.95 in the US or £13.95 in the UK, see here
