Virgin Islands

Since I seem to be doomed to posting mammalwatching trip reports from places where nobody would ever go for mammalwatching, here’s another one, a 1-page mammalwatching guide to the Virgin Islands: I spent a few days there back in July 2000 and saw 7 native species. Vladimir Dinets

Puerto Rico

I just came back from a very short family vacation to Puerto Rico. Since it was my third trip there, I summarized everything I know into a 2-page mammalwatching guide to the island: I saw 14 native species there in about a month total time.

Acouchi in Bolivia?

Hi guys,   2 weeks ago I had the pleasure of being in the Jaguarland/La Moneda Reserve in Bolivia. There are quite a few tripreports of this place now on this website. I saw a lot of good stuff but one mammal had us puzzled. It seemed to resemble Agouti the closest, but it was much smaller and also moved […]

Mammal ID from Chaparri, Northern Peru

Hi All, I am looking for help if anybody knows rodents in the Chaparri area of Peru (north-west)! This is the area: I saw small mammals (rodents) every evening around the cabins. Perhaps the same species all the time. I post 4 images – could be the same species… Could not find any publications about any small mammal trapping […]

I’ve been thinking of how one could make a friendly mammal watching competition were you have to watch in the country you live in that is relativly fair no matter were you live and making the results between countries comparable. It can’t be how many species you see as the diversity is much higher in eg. Kenya than Denmark. Making […]

Mammal Big Day – Southern Kenya – A landscape report

On October 1st, 2021, a friend of mine (Stratton Hatfield) and I commenced a mammal big day across the Mara-Loita-Nguruman landscape of Southern Kenya, covering roughly 100 Nautical Miles (1 ‘minute’ of latitute).  Our primary purpose was to showcase the immense diversity this region has to offer and to try to shed light on some of the conservation challenges this […]

Western sahara

My 6 day trip to Western sahara. I flew on the 20th October 2021. A straightforward flight, from Gatwick, via casablanca to dakhla. The only issue being landing in casablanca to find that our flight home had even cancelled due to covid rules being suddenly changed by the Moroccan government. Not exactly ideal. Post covid, dakhlas windsurfing Community is alive […]

Taxonomy news

1. True’s beaked whales from the Southern Hemisphere split as a new species, Mesoplodon eueu. 2. When pygmy marmosets got split, it was unclear which of the two species should keep the old name because it was unknown which one was represented by the original holotype. Now we know that the northern species should be called Cebuella pygmaea and the […]

A Hypothetical Question – Just for Fun

Hi Everyone! I’ve been entertaining this question in my own head, and was wondering what everyone else thinks: So back when I started mammal watching (2007ish), seeing a list of 20-30 mammals anywhere was spectacular, and 50 was almost unimaginable. But obviously, with today’s knowledge, increasing accessibility to ecosystems at night (in most countries), improving guiding services and of course […]

    Hello blog,
    I wish to organize a 10-day stay in Nepal in mid-February 2020 with my family (including two of my boys aged 12 and 14). I would like to visit the Chitwan National Park first and then move towards either the Bardia Park or a trek in the Langtang Valley.
    So I have several questions: on Chitwan, do you know a good guide or good lodge to organize a stay of 3/4 days accés mainly on the mammals watching?
    On Langtang, I would like to organize a trek to try to see the red panda and the Himalayan Thar. Do you know an agency or specialized guide in Nepal to offer a trek of 3 days in this zone?
    Do you know if the Red Panda is visible in the Langtang area?
    The trip will be organized around mid-February and I do not know if the valley is passable at this time?
    If this is not the case, I will move towards a 3-day stay in Bardia Park. Here again, do you know a guide or a lodge that specializes in mammals?
    I’m a little afraid that Chitwan and Bardia are quite similar in wildlife. For that I will first of all go towards the possibility of Langtang.
    I am interested in any information.
    Thank you in advance.
    Best regards.
    Philippe Paraire

    New trip report for Southern Israel – Negev desert (5 days)



  9. Manuel Ruedi 10 months ago

    Dear Mammal watchers. While doing research in NW India, Himachal Pradesh (near Solan), we came across a small, greyish mouse with an elongated face. We collected it hoping to be able to ID it, but unfortunately it proved to be an immature animal so measurements were not convincing. We barcoded this mystery rodent, but no match exist in public genetic repositories…
    I recently posted on iNaturalist pictures of that mystery mouse (, but received no suggestion.
    Would you have an idea ? I am really bad with rodent ID…

    Dear Jon,

    Great website! My friend Bob Dowler told me about it. I just wanted to point out an error in the species list for Mexico. In it you have an image of “Peromyscus chrysopsis”. There is a harvest mouse species (Reithrodontomys chrysopsis), so perhaps that is what you caught?

    Keep up your good work of promoting mammal conservation!

    Take care,
