Mammals of N Tibet: 2-15 Oct 2005



An at-a-glance list of 14+ spp of mammals (& birdwatching highlights).
By Jesper Hornskov ***all rights reserved ®*** [this draft 23 Feb 2012]
Please note that the following list is best considered a work in progress. It should not be quoted without consulting the author.
This write-up covers a trip undertaken by A Guillemont, J F Terrasse, M Terrasse & myself.
Thank you for making the journey so enjoyable!
The mammals, the birds (149 species in total), the unbeatable scenery, a stimulating mix of local cultures, wonderful food, comfortable accommodations & (not least) the companionship all came together to produce a trip the more memorable for the region being so under-visited by mammal-watchers.

Inquiries concerning future trips to NE Tibet or Yunnan - our trips to China’s biologically most diverse province have been very popular - can be made directly to this author.
We are currently planning a NE Tibet Mammal Special for autumn 2012. The itinerary is inspired by / based on the trip covered by the present write-up, but it has been comprehensively fine-tuned drawing on experience gathered over the intervening years.
In the species list the concept "animal-days" is used - it is the equivalent of man-hours, the day totals added up – it indicates relative abundance but does not consider the “problem” of lingering individuals or, important in a non-scientific context such as a natural history holiday abroad, how satisfying the encounters were. 25 animal-days for e.g. Goitered Gazelle could be one distant herd vanishing in a cloud of dust before you’d had a good look at them, or one individual lingering for 25 days, offering the observers point-blank views anytime in that period…

The sequence of the mammal list follows “A Guide to the Mammals of China”, Smith & Xie (ed.) 2008, while in the list of bird highlights I have followed The Howard and Moore Complete Checklist of the Birds of the World – 3rd Edition (Dickinson 2003), in my opinion by far the most useful one-volume checklist to date.


Initials in brackets after a few single-observer sightings does not imply that I have doubts as to the correctness of the ID!

Mammals:
Red Fox Vulpes vulpes

One seen at close range on 6th.

***In addition, one was found killed on the road along the S edge of the Qaidam. Zhang (1997) listed

the species for nowhere closer than Delingha, roughly at the same longitude but on the N edge of the

basin.
Tibetan Fox Vulpes ferrilata

Noted on four dates - 25 individuals in total; daily max 16 on 6th.

***One on 13th was seen hunting a pika: running up, then back, body straight as a board but reaching

an impasse where any next inch of progress would reveal the fox’s presence in time for the pika to dive into its safe burrow. That’s how we left them, in the snowy landscape…


Asian Badger Meles leucurus

One at long range S of the Maduo wetland on 6th.


Pallas's Cat Felis manul

3-4 on 5th & one [AG] on 8th.


Kiang Equus kiang

1,323 animal-days, concerning no less than 1,251 individuals noted on five dates.


Wild Yak Bos grunniens

626 individuals counted: 625 in ‘Yak Valley’, and a distant (10kms!?) lone bull on 13th.


Goitred Gazelle Gazella subgutturosa

56 animal-days. Noted on three dates.

***In the time-honoured way we worked hard for our first sightings only to see more easily later on…
Tibetan Antelope Pantholops hodgsoni

335 animal-days, relating to 287 individuals noted over two days.

***Some were close enough to photograph.
Tibetan Gazelle Procapra picticaudata

1,072 animal-days, relating to 992+ individuals noted on five dates.


Przevalski’s Gazelle Procapra przewalskii

A group of nine (a buck with four females each with a youngster) was an exceptionally good find.

***The species has recently be ‘downgraded’ to ‘merely’ Endangered (following the discovery of additional herds in 2003) although the world population may be no more than 350-400 mature individuals. See http://www.iucnredlist.org/apps/redlist/details/18230/0

***Our animals appear represent an additional ‘undiscovered’ population.


Blue Sheep Pseudois nayaur

13 animal-days. Two on 5th, six on 13th & five on 15th were all at considerable distance and fewer than we might reasonably have expected as previous, bird-centered trips have yielded groups of up to 30+ animals.


Argali Ovis ammon

67 in ‘Yak Valley’ was a great bonus, particularly as some allowed extended viewing at reasonable range.

***”Seeing Argali, Wild Yak & Kiang in the same ‘scope field-of-view on a hillside is about as much as one can hope for, mammal-wise, in this part of the world.”

Himalayan Marmot Marmota himalayana

One on 4th.


Black-lipped Pika Ochotona curzoniae

Widespread.


Woolly Hare Lepus oiostolus

Fairly widespread.
