Global Mammal Checklist: new update

I have just uploaded an updated global mammal checklist (here). The first update in 12 months. The checklist began life as something primarily based on the IUCN Red List. But the Red List taxonomy is sometimes quite out of date for some groups of species, so I am moved to using the American Society of Mammalogists’ (ASM)  Mammal Diversity Database (MDD) as […]

Taxonomy news

1. A new paper argues that red mazama deer south of the Amazon should be considered a separate species Mazama rufa rather than M. americana. 2. Myotis keaysi from coastal Ecuador split (open-access) as M. moratellii. Apparently this is the species that used to roost in public bathrooms at Cerro Blanco back in 1995. No idea if they are still […]

Bobcat Update, Tucson Arizona

Sweetwater Wetlands is a small urban park off of I-10 in central Tucson. As of January 2022, four different bobcats have overlapping ranges here. Winter seems best; sighting success is between 50-75%. In summer that drops to more like 10%, though there are Arizona cotton rats then, round-tailed ground squirrels, and things like vermilion flycatchers and dragonflies. Birding is good […]

    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 1 year 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,
