Massacre on Marion Island

Some really bizarre information in this one. 

The remote Marion Island in the Indian Ocean is scene to a "zombie apocalypse" during which aggressive and hungry mice prey on the seabirds, including large albatrosses, and eventually kill them. Or, not to put too fine spin on it, eat them alive under torture-like forms. 

Homo sapiens has decided to come to the rescue, and in 2026, the plan is to kill off the mice instead. That is, to exterminate millions of them! So our response to the zombie apocalypse is mouse genocide. Not until 2028 will we know whether the pesky rodent is finally gone and our tubenose brethren saved. Oh, and in a previous hominid killing spree on the island, all cats were extirpated?! 

>>>A “zombie apocalypse” has been playing itself out on Marion Island in the Southern Indian Ocean for more than a decade, as flesh-eating mice massacre vulnerable seabirds, having already laid waste to invertebrates and otherwise tenacious vegetation.

>>>In the 20 years up to 2018, the number of mice on Marion increased by about 430%. As a result, says Anderson, “the frequency of mouse attacks is increasing very significantly. It’s exponential, and it’s related to the fact that the invertebrates on which the mice used to prey have been decimated, so the mice are feeding off the seabirds and their eggs as an alternative food source” to replace their diet of weevils, moths and seeds. 

>>>In a 2015 study, mice were found to be killing one in 10 albatross chicks. Not only has this escalated, says Anderson, but “one of our concerns is that the mice are now starting to feed on adult wandering albatrosses as well. “The loss of chicks obviously has a big impact, but once you start killing adult birds of breeding maturity, then the impact on populations increases. And this is a more recent phenomenon.”

It´s become something of a gimmick here on the blog to post pics of particularly well-endowed young women everytime a Chinese spy balloon enters US air space or an American bank collapses. However, this has now become so common that the blog might run the risk of looking, shall we say, highly suggestive. 

So from now on I will instead post pics of rare birds whenever the events mentioned above take place. I expect this to be something of a weekly feature in the months and years ahead...

Birds in the monastery

“Ireland's Wild Coast” is a documentary directed by Cepa Giblin and John Murray. The latter is most known for his award-winning “Broken Tail” about Indian tigers. After the inevitable stint in the tropics, Murray returned to his native Ireland and help direct two documentaries about its stunning nature and wildlife, the first being “Ireland's Wild River” about the Shannon.

In “Ireland's Wild Coast”, we are introduced to the Irish Atlantic coast, from Skellig Michael in the southwest to County Donegal in the northwest. Animals featured include seals, whales, basking sharks, blue sharks, outcast dolphins (sic), seemingly feral sheep and a wide variety of birds. At Skellig Michael, Manx shearwaters nest in an abandoned medieval monastery. Donegal turns out to be the winter quarters of whooper swans from Iceland - perhaps the only migratory bird spending the winter in Ireland!

I admit that I found “Ireland's Wild Coast” fascinating. The underlying theme of this production is wildlife taking over after humans leaving. In real life, of course, it's the other way around. Murray himself pointed out when interviewed by Swedish television that Ireland, previously regarded as the end of the world, has become one of its most exploited spots…

Five stars. For the documentary, that is.

An odd job

This is the revised edition of "Seabirds - an identification guide" by Peter Harrison. The author, who actually looks like an old fashioned sea captain, and his wife Carol spent seven years on the world's oceans to gather information for this field guide to end all field guides. Gee, don't these guys have day jobs? Maybe they do, after a fashion: Harrison worked as a deckhand aboard trawlers and crayfishing boats to more easily study and sketch seabirds. I wonder what his crew mates made of that!

As you might have guessed, "Seabirds" is illustrated by deckhand Harrison himself. Personally, I'm a bird book-watcher rather than a birdwatcher, so I tend to buy bird books for aesthetic reasons. I admit that Harrisonian aesthetics weren't really to my liking, but then, I'm a Jonsson aficionado. The selection of species is also somewhat arbitrary: very few shorebirds, but a whole lot of pelicans, cormorants, loons and grebes. Even grebes that don't live anywhere near the sea have been included. The exceedingly rare Atitlan Grebe can be found only in one lake in Guatemala (if you're lucky). That's a seabird? As for ducks, a representative selection has been included, but only in an appendix with illustrations in black-and-white. Do crayfishers have a secret conflict with eiders?

Otherwise, "Seabirds" looks like most field guides are supposed to look like. There's an extensive colour plate section, and in the main text section we get information on distribution, juveniles, various plumages, similar species and some special tips concerning identification. A problem is that the maps are tucked away in a third section at the back of the book. The colour plates don't indicate distribution. I was somewhat surprised to learn that both the Northern and the Southern Giant Petrels are confined to the South Atlantic, and that the "southern" species have a more northern range! Any explanation? Or just one of those "odd jobs"?

Still, I don't doubt that this is the field guide if your favourite haunts include South Georgia, Kerguelen, Antarctica or...Lake Atitlan. Four stars!

Birds at sea

A review of "Seabirds: A Natural History".

Anthony J. Gaston is an ornithologist who worked for 30 years for the Canadian Wildlife Service, specializing in the ecology of seabirds. He is therefore eminently qualified to write a general natural history of birds found mostly at sea: albatrosses, petrels, auks, boobies, etc.

I admit that I only skimmed his book, since most of it is rather technical and "boring" from the perspective of the general reader. However, I don't doubt that this book could be of considerable interest to students of ornithology, or perhaps very advanced bird-watchers.

All aspects of seabird natural history seem to be covered: coloniality, feeding behaviour, plumage, the life cycle, distribution, extinctions... There are very few illustrations, but the few colour photos are excellent. The author has also thrown in some personal anecdotes from his years as a researcher.

All in all, this looks like a relatively good book on the subject, so I give it four stars. But, as most volumes in the Poyser series, it's mostly for scientists.

A handbook of exciting birds

"Handbook of the Birds of the World" (HBW) is a 13-volume encyclopedia whose ultimate aim is to describe and illustrate *all* living species of birds. Three more volumes are projected. The series began in 1992, and the last volume won't be published until 2011.

This is the first volume, and it covers many exciting bird groups, including pelicans, tropicbirds, frigatebirds, penguins, flamingos, albatrosses, and the non-flying birds, such as the ostrich and the emu. It also covers a more boring bird group, namely the ducks! Each section begins with a general introduction, followed by species presentations. These include color plates and range maps. Unfortunately, the color plates are quite bad. The birds often look caricatured, even ugly, and some of the plates are poorly printed. Thankfully, the book also contain hundreds of photos, all in color, and these are much better. Despite its high price (265 dollars), the book is well-worth buying if you are seriously interested in these particular bird groups.

As already mentioned, this is just the first volume in a 13-volume series. Naturally, a work that takes almost 20 years to publish, will tend to change over time. I noticed this when I leafed through the other HBW volumes at my local university library. The first volume looks like a regular encyclopedia. Anyone with a general interest in birds can read it. The later volumes are superbly illustrated, with much better color plates, but the text feels heavy and technical. These later HBW volumes also suffer from total information over-load. Essentially, the HBW has been transformed from a regular encyclopedia to a scientific reference work for ornithologists.

Be that as it may, I give this first volume of the HBW four stars, for the text and the photos. Had the color plates been better, I would have given it five stars. The entire series also deserve five stars, despite becoming progressively more difficult to digest for ordinary mortals, since it's extremely well-produced.
