As i've just added a few days in Kuwait to next year's Saudi Arabia tour, mainly as I think it would a really cool addition to an already successful trip, but also as this small Middle East country is apparently just at the edge of the Western Palearctic..... Well it opens up a whole new angle on reasons to go there...... The good old WP List. And as i've been largely ignorant of the interest in listing in the WP region, I have been doing a little research. It seems a bit silly now, thinking about my WP ignorance, as at one time or another i've chased birds for my Plymouth list, Devon list, UK list, India list, more recently my Oman list and i've racked up a reasonable world list. But a Western Palearctic list hasn't been on my radar. Well, until now. And actually i'm really impatient to see the stuff in Kuwait and put some WP rarities onto my own list.... Species like Afghan Babbler, Crab-Plover, Socotra Cormorant etc etc. Having done quite a few trips in Saudi and Oman, I can't get into the whole Greater Western Palearctic listing thing - it's just too much of a stretch. But keeping things in the confines of this man-made boundary of the 'Western Palearctic' is something I could subscribe to. But saying that I haven't a clue what my own WP list is!
But lists are part and parcel of being a birder right. We all keep lists of some type and some birders have a list for anything. There's the basic stuff, like garden, city, county, national, world or year lists, there's the more unusual stuff, like a pee list, window list or a 'birds seen on t.v' list and even the tongue-in-cheek 'roadkill list' whilst on a tour. But it does seem that many birders in Europe, Northern Africa and the Middle East actually keep a Western Palearctic list. I've been a bit interested in my Oman list of late but as it turns out I'm rubbish at keeping lists updated.
So now i'm interested in just what comprises the boundary of the Western Palearctic.....
So here's a map showing the long-established boundaries of the WP used by most authorities and birding websites. These boundaries were defined by Cramp (1977) and published in the 'Birds of the Western Palearctic' series (BWP).*
The map below shows the new approach to define the region. The definition used for this map stems from Mitchell (2017) from 'Birds of Europe, North Africa and the Middle East. An Annotated Checklist'. A mostly similar definition i'm told is in the 'Handbook of Western Palearctic birds' series by Shirihai and Svensson. But I haven't got a copy of that book yet.
The third map below compares both definitions. The 'GWP' includes all of the 'WP' plus the Arabian peninsula, Iran and some more of the Sahara.
The geographical limits of the Western Palearctic are as defined by the nine-volume Birds of the Western Palearctic - basically Europe, North Africa and a block of the Middle East roughly south and east to Kuwait, but not including Iran nor anywhere east of the Urals and Caspian Sea. For more precise definitions, see BWP.
Currently the WP List stands at 1,069 species. Amazing huh?!
The boundary is set at the 27th parallel so Kuwait for example is in but Bahrain is out.
In an increasingly competitive ‘WP listing’ field, the late Ernie Davis is three species clear of Pierre-André Crochet of France, and six ahead of Chris Bell from Co Durham. Based on BWP boundaries, just 18 birders have so far passed the 800-species mark, with 71 on 700 species or more.
I believe the record for species observed in the WP in a single year is 761 but a team of 3 Swedish birders.
I'm happy to be corrected about any of the above and realise the boundaries are subjective and open to interpretation - and not to everyone's taste. But i've found it fascinating to research this.
At the risk of making this post too long, i've cribbed some more in-depth info from another website:
Here's the definition for the Greater Western Palearctic (Mitchell 2017), with some comments:"The northern boundary extends into the high Arctic to 82°N, to include Novaya Zemlya, all of Franz Josef Land and Svalbard, then west to 10°W and south to the Arctic Circle, so excluding Greenland but including Jan Mayen. It follows the Arctic Circle west across northern Iceland, extending north slightly to include Icelandic territorial waters (12 nautical miles from shore), then at 30°W turns south to the Azores, with a minor westward extension to include Corvo, Flores and surrounding territorial waters in that archipelago, before continuing south along 30°W. At 14°N, the boundary runs south of and thus includes the Cape Verde Islands, before heading north at 20°W and then east again at 19°N to the Mauritanian coast. To the north, the islands of the Banc D'Arguin fall within the region but the adjacent mainland coast does not, the boundary lying on the low tide midpoint between the two. From the Mauritanian coast, the boundary runs inland east at 20°N through the southern Sahara to northern Chad, thereby including the Hoggar, but not the extreme south of Algeria nor the Aïr Massif in north-west Niger. Between 16° and 20°E in northern Chad the boundary runs farther south at 18°N to include the Tibesti but not the Ennedi, then east at 20°N again to the Egyptian border. The regional boundary follows this border east along 22°N as far as Gebel Elba, where at about 34°E it moves north-east, thus excluding this Sudan-administered Egyptian territory, and reaches the Red Sea at about 22°N (sic!). All of the Arabian Peninsula is included within the region, as is all of Iran. The eastern border of this region extends into the north from the Kara Sea east of Novaya Zemlya, the north-eastern tip of which represents the most easterly point of Europe, south along the Ural ridge (following administrative boundaries) to 58°30'N, thence by an arbitrary straight line to a point 50 km east of Yekaterinburg, and by another arbitrary straight line to the head waters of the Ural River south of Zlatoust., and then south along the Ural River to the Caspian Sea, the boundary continues south along a theoretical meandering line midway between the west and east shores until it meets the Iranian border with Turkmenistan to the south-east."This definition seems exhaustive and precise at first glance and is probably much more precise than the definition by Cramp. However there is still some vagueness at some points, which I'll list below:
- The westward extension around Corvo and Flores is not clearly defined. I suggest the following extension: 30°W 40°N -> 32°W 40°N -> 32°W 39°N -> 30°W 39°N
- The map and the text in BENAME do not conform with each other at the Tibesti extension, as 16°E lies slightly east of the Niger-Chadian border, which is used as a guide line in the map. I suggest to stick with the text definition.
- It is unclear whether the boundaries follow the political boundaries or the 20°N latitude at lake Nasser, as Sudanese waters reach north of this latitude. I suggest to use the 20°N latitude.
- There's a minor extension south of 20°N at Gebel Elba which is not accounted for in the text, but in the map in BENAME. I suggest this should be added to the definition.
- There's a mistake in the text definition, after moving north-east along Gebel Elba. It should read "(...) reaches the Red Sea at 23°N" instead of 22°N
- The oceanic boundaries around the Arabian peninsula are not clearly described. I suggest a meandering line between the east and west shores of the Red Sea south to ca. 43°50'E 12°30'N, then 12 nautical miles from the shore of the peninsula
- The eastern boundary in Russia and Kazakhstan is depicted completely wrong in the map of BENAME. Neither does it follow the Ural River, nor the Ural ridge and even the dent around Yekaterinburg is depicted far to the west.
There are three main differences between the WP and the GWP:
- In the WP definition by Cramp the boundary along the Mauritanian coast runs north to 21°N (as opposed to 20°N) and then eastwards from there towards the Tibesti dent
- The Arabian peninsula is largely excluded. Instead a straight line along the 28°N latitude cuts through Saudi Arabia
- The south-eastern boundary used is not the eastern, but the western border of Iran and its neighboring countries
I hope this post can help clear most questions about the boundaries of the WP and the GWP. A commentary on the pros and cons of both defintions will soon follow.
*The boundaries in the Caspian Sea and in the ocean around Kuwait aren't clearly defined in BWP. I therefore assumed borders that are in fact non-existent. Furthermore the lines drawn in these regions aren't exact as drawing them would be a pain in the *** without any reference line I can follow. Sorry for that)
