I’ve been interested in animals since I was a toddler living in North Wales. As this letter to Father Christmas shows, I was building a mammal list when I was 7, even if these were plastic mammals for my toy zoo. Those capable of reading my disastrous writing will spot a worrying interest in birds. Thankfully this passed.

It wasn’t until I left the UK and spent 1991 in Zambia that I really got into mammal watching. Since then I’ve lived in Australia, France and now New York City, and looked for mammals in over 100 countries (I know…. but I do now offset my carbon emissions).

My life list is here. I firmly believe mammalwatching is a road to happiness and have some science to back me up! If you really want to know more then tune into episode 3 of our podcast.

I sent up this site in 2005 as a way to share the sort of information that birders enjoy. If you have any content, comments or suggestions I’d be glad to get them: just drop me an email.

Happy mammal watching.

    I had a look at the list of Mammals of the world and i have found something new for me
    Are Artiodactyla and Cetacea in the same Order Cetartiodactyla ??? what is the source or the reference please.
    I am working on establishing the taxonomy referential of the 111 species of wild mammals of Algeria and i want to have results with the newest data of the taxonomy.
    Can you advice me a site or a reference in the web where i can found the newest taxonomy of the mammals?
    Thank you very much

    Nice to see this site. I run @Lanka_Wildlife and work on palm squirrels. Post videos sometimes about mammals to that twitter site regularly. Would be good to share my videos with a site like this. Any feedback, feel free to contact.

    John I write to you because there are a guide in Peru. In a very small town. And with all this mess his family and he are hungry.
    He is the guide for the Colocolo cat and Andean cat in Ondores.
    I went there two years ago and we got along. We began a friendship.
    I have helped him in several occasion during these past months.
    I don’t know if this is appropriate but I want to try anyway. I would like that you write a post about this situation and see if anyone would like to help him and send him some money.
    They live with very little.
    If you think that this is not a question for this web, I will understand.
    If you want to know further details contact natrodpar@yahoo.es

      Natalia, I think the best thing would be for you to write a report of your trip so that the guide might get some business soon. Of course you can mention that times are tough for him in that. As you can imagine a huge number of nature guides are struggling these days and I would prefer not to flood the site with requests to help them all. I am glad you are helping him. thanks

    Dear John,
    I hope this message finds you well. I am writing form Ithaca, New York, but I am from Tajikistan. I found this website through my friend, very interesting. Some years ago, I organized wildlife safari to Tajikistan and we counted some wild sheep and goats. I even made a short video about it. I would love to upload the report on behalf our team, but I am not sure how I do that. It would be wonderful to see Tajikistan in the websites of mammal watching.
    Thank you,
    Daler Kaziev
