2025. Welcome to the quarter point of the century, folks. Your reward: a new challenge! Available for a limited time in North America only ;)

As primates living in troubled times, what gets us through life is togetherness; as Bill Withers would say, “Lean on me…” And what better way to remind ourselves the importance of community than by joining with your fellow North Americans to count up all the social mammals you see at zoos in 2025?

What counts as a social mammal is listed below. I did my best to 1) include mammals that routinely socialize in groups larger than pairs; 2) get a sampling from different orders for group diversity; and 3) not make things too complicated by picking and choosing different species from within the same families. Based on my own list of captive mammals I’ve seen, this should break down to about 1/3 primates, 1/3 ungulates and 1/3 other mammals. Of course, this wouldn’t be Zoochat if someone doesn’t disagree with me on something, so feel free to critique this list with possible additions or subtractions as you see fit – while keeping in mind that I am now too old and ornery to debate any specific point for long:

Primates: all species *except* gibbons, orangutans, lorises, and aye-aye

Ungulates: all species *except* Pygmy Hippo; Black and Indian Rhinos; Okapi; tapirs; and small deer/bovids (duikers, pudu, muntjac, tufted deer, klipspringer, mouse deer, etc)

Bats
Cetaceans
Elephants


Marsupials: kangaroos and wallabies

Rodents: Squirrels, mole-rats and cavies (capybara and mara)

Carnivores: “pack canids” (Canis, Painted Dog, Dhole and Bush Dog); Lion; mongooses; otters; pinnipeds; and Spotted Hyena

---

As always, a quick shoutout to @Shorts for creating the original game and the template we still use. Now, the rules:

1. You have to actually see the animal, even if just for a second.

2. Photographic proof is not required; your word is your bond.

3. All entries must be in a numbered list and include the following: the species you’re counting, the day you saw it and the zoo you saw it at.

4. All animals must be seen in captivity in North America (Canada, the United States, or Mexico); in a public zoological collection (no farms, expos, pet stores, private or exclusive facilities); and via normal public access during normal public opening hours (no behind-the-scenes or VIP tours, exclusive events, etc.).

5. Report your progress on this thread as you go along; do not leave all your updates until the last minute. If you post several months’ worth of updates late in the year, I reserve the right to not count some or all of them. Non-new members waiting until late in the year to join with a high score are, from my POV, doing the same thing and I reserve the right to not count some or all of these late entries also. This is to ensure fairness and transparency for everyone.

6. The taxonomy source we will be using is IUCN. Our unit is species, not subspecies.

7. Hybrid animals and domestic animals do not count unless an exception is made.

8. Violating the rules or participating in unsportsmanlike conduct is grounds for disqualification from this year’s competition and/or from future North America challenges.

9. The winner will be whoever sees the most social mammal species between January 1 and December 31, 2024.

---

And with that, the challenge begins tomorrow. I will be on vacation from January 1 (tomorrow) through the 4th, so I may not respond quickly to questions or comments in the first few days but I promise I’ll get to them by next week when I have more time. Until then... let the games begin! But, you know... tomorrow :p

American Black Bear? They're very social animals.

I wasn't under the impression that any bear species was particularly social; I skimmed a couple of abstracts of research papers detailing black bear social behavior and it seemed to indicate they are mostly solitary. I know that bears will congregate around plentiful food resources (ex. garbage dumps, salmon runs) but that's not quite the same dynamic.

In any case, it would be another overlap species from last year's challenge - so I think leaving it out is fine, even if it happens to be more social than I assumed.

15. Dingo (Canis familiaris)

Technically shouldn't count under IUCN taxonomy, but since I did make an exception for it last year I suppose it makes sense to treat it the same way this year.

Rule Modifier: as an exception to the IUCN taxonomy and domestic rules, Dingo/New Guinea Singing Dog can be counted this year as a single species, Canis familiaris.

And another rule modifier I forgot to address:

Reticulated/Rothschild's (generic) Giraffe and Masai Giraffe can be counted as two species, despite IUCN still only recognizing one species of giraffe.

American Black Bears were assumed to be solitary until fairly recently, when their extensive social structures have begun to be studied (I highly recommend the book In The Company of Bears by zoologist Benjamin Kilham for more on this, if you're interested), but fair enough on the overlap.
 
Question-
Do nature centers count towards this challenge?

They certainly can, assuming they meet the other requirements (captive animals on display to the public, with regular viewing hours or regularly scheduled tours).

Also, another taxonomy note I forgot to add: in line with the primate challenge from 2023, Chlorocebus monkeys (vervet, grivet, green monkey, etc) will only count collectively as one species - due to the unknown/mixed origin for most of those monkeys in US captive collections.

These species are not eligible, so you are at 26.

Cool to see that Franklin Park has Large Flying Fox now! Must be a new holding, they used to only have African bats.
 
New year, same first zoo! I was shockingly able to see almost every eligible species, just missing the silvery lutungs (which are temporarily off-exhibit), the slender-horned gazelle, and the common dwarf mongoose!
