Sequence: Bunch of chimps travelling

    ACP00058f5
    Video starts with rather big, robust chimp with a bald forehead and several bald spots on its body - they can be seen in the video, snapshot is difficult:
    enter image description here

    Followed by a female with a juvenile on its back:
    enter image description here
    There is a shot of Amy and River in the same location - so it's maybe them?

    ACP00058f6
    a smaller chimp (female) that reminds me of Pearl - very broad, light muzzle, only a small black strip between the eye - turning around as if waiting for the next chimp to follow
    enter image description here

    ACP00058f7
    the next seems to be more robust than the previous, but not as big as the first one, light face and eyebrows, long face
    I tried to get a good snapshot but didn't succeed

    ACP00058f8
    must be Dodge as right forearm is missing

    I tried to insert the pictures directly, but the size doesn't fit - if someone tells me how to do it, I will edit the post 😃
    I'll be going through the list of IDed and prospective chimps to compare right now 😃 except for Dodge, please note that these are no "official match propositions"

    To put a photo in the post, click on the little button right above the text box that looks like a polaroid (white border with stripes of blue and green) -- it's next to the button with 101010 on it. A box will pop up for you to paste the URL into, then click ok. It will have added text to your post that starts with an exclamation point and ends with a parenthesis and includes the URL of the photo. If you click on the blue "Show Preview", the photo should now appear in the post.

    I think it might resize based on the size of the screen. But it's also possible to tell it to use a particular size. If you click on the button and have it add the text to make the photo appear, the last part of what it adds is something like:
    5520393b69736d72e6934802_9.jpg)

    You can tell it what size to use by inserting a number at the end, for example, to make it 600 pixels across, add:

    5520393b69736d72e6934802_9.jpg =600x)

    I usually use 500 or 600, but if the details are small, I'll leave it full size. Whatever you think looks good 😃

    Going through prospective males I think that the first chimp in the sequence could be CDMale04 - ears close to the head, bold stripe on the forehead - I also think that it looks a bt like CDMale04a but I'm not sure because of they eyebrows...

    Thank you - changed it
    Is there also a possibility to do snapshots by myself? The 15 shots under the video are not so good in most of the cases

    Unfortunately you can only choose from the 16 previews 😕

    Other than that, you can tell people at which second or between which two previews you see something.

    I thought that lone female might be CDFem04, so I posted to her thread: http://talk.chimpandsee.org/#/boards/BCP000000k/discussions/DCP0000a5o?page=1&comment_id=55c0370acc1b5742ea000e77

    Hi all, nice sequence!

    • ACP00058f5 : I would like to propose this male as match with CDMale07, so from now he will be CDMale07a. And then Amy+River.
    • ACP00058f6 : proposed as CDFem04, but I am not sure, so for now CDFem04b
    • ACP00058f7 : juvenile, but too fast to ID
    • ACP00058f8 : Dodge

    Nice find!

    Wow, I got one right 😃

  • jwidness by jwidness moderator

    I agree about CDMale07 -- this video was on my list as a match to CDMale01/01a/05/03/07, but I guess I didn't make that comment in the forum

    Maybe it helps to compare this sequence to the following, as it shows a similar order of individuals and is on the same place - is it possible that it's the same group of chimps?
    This sequence is from 2013-12-06
    The other one above from 2013-03-06

    ACP00058d1
    Starts with a big and robust male, that has been proposed to be CDMale 06 by @jwidness here: http://talk.chimpandsee.org/#/boards/BCP000000k/discussions/DCP0000aoz

    enter image description here

    He is followed by a female carrying a young
    enter image description here

    (I'm really not good at distinguishing chimps as I I just found ot, but I think they're very similar to Amy and River again)

    Afterwards comes another female carrying an infant on her belly
    enter image description here

    What striked me most was that she is turning around as if waiting for some other chimp - just as the third chimp in above's sequence

    enter image description here

    There's a link from this clip to a discussion about CDFem09 CDFem09a and CD Femo9b: http://talk.chimpandsee.org/#/boards/BCP000000k/discussions/DCP00009l3

    ACP00058d2
    The chimp that the female has been "waiting" for shows up here and shows similar behaviour to the juvenile in the above sequence (first interested in a bush on the left - this time even sitting down for a short while)- then quickly catching up with the rest of the group in ACP00058d2)
    It seems to be a female - at least I cannot see any testicles here
    enter image description here

    The sequence is completed by ACP00058d4 where no chimp is seen but a rustling sound can be heard

    I was so striked by the similar behaviour that I had to post this - but I don't feel capable to really describe them - and I'm way too far behind to even try to ID them - I have to admit that I lost track - there's so much information and you're working so fast... Hope my little attribution can help, though 😃

    I just read the thread about the eight chimp group ACP000587x ACP000587y ACP000587z
    http://talk.chimpandsee.org/#/boards/BCP000000k/discussions/DCP00009vn

    As the first male in both sequences seems to be the same (proposed as CDMale06 by @jwidness) it may be rather this group than the one I put together in first place - even more so as there is no sign of Dodge here
    Group of eight chimps is:

    Male (CD06?) // CDFem09a + baby // Juvenile (Fry?) // Pearl + Flocke // Amy + River

    I am confused now... I hope I didn't confuse you... I have no idea how to keep all of this information...

    (Please, if I am doing anything wrong or confusing, just tell me and I won't continue!)

    Hi Mercury82,
    are you asking if these two groups could be the same?

    http://talk.chimpandsee.org/#/subjects/ACP000587x
    http://talk.chimpandsee.org/#/subjects/ACP000587y
    http://talk.chimpandsee.org/#/subjects/ACP000587z

    http://talk.chimpandsee.org/#/subjects/ACP00058d1
    http://talk.chimpandsee.org/#/subjects/ACP00058d2
    http://talk.chimpandsee.org/#/subjects/ACP00058d3
    http://talk.chimpandsee.org/#/subjects/ACP00058d4

    Yes, they could be the same. The males are the same, then CDFem09, Amy and River, and the last chimp from the second group pass very fast, but yes, they could be the same.

    I am going ti try to put also these images in the known/prospective list to help you.
    You are doing veeeeery well!!

  • Mercury82 by Mercury82

    Yes, I think, that's what I wanted to say 😄 😄 😄

    But the first group (ACP00058f5 ACP00058f6 ACP00058f7 ACP00058f8) led by CDMale07, then Amy&River, CDFem04b, juvenile and Dodge is a different one?

    Just to get it right: wouldn't it be weird to have Amy and River travelling with different groups?

  • jwidness by jwidness moderator

    It would not be weird to have Amy and River travelling in different groups on different days. Chimps live in what is called a community that ranges in size at different sites. Crimson Dew appears to be at the smaller end of the range in size for communities -- 15 individuals is around the minimum size (I don't know the exact minimum recorded), but communities can be up to around 200 individuals, for example Ngogo in Uganda. Within the community, chimps will "fission-fusion" -- that is, they will come together into parties that last hours or days, and then they will split apart again and join with other individuals in the community. It's entirely possible to never actually see two individuals that belong to the same community in a party together! Smaller communities (such as CD) seem to be more cohesive and spend more time together. See http://www.eva.mpg.de/primat/staff/boesch/pdf/behav_eco_soc_fiss_fus.pdf.

    Thank you! How interesting! I had no idea - I thought they were living in kind of "family groups" - I learn something new everyday
    (Hope my stupid question are not too disturbing you - and I thank you a lot for answering them alsways and so fast!)

  • jwidness by jwidness moderator

    No problem! Chimps are always interesting to talk about 😃

    As a side note, western lowland gorillas do live in the kind of family group that you're thinking of. One silverback male will live with a few adult females and their offspring. But to be completely honest, this is not 100% true of all gorilla groups, and it's certainly not true of all mountain gorilla groups -- their groups contain more than one adult male around 40% of the time, with one group known to have around 7 adult males at once! (I don't remember the exact numbers, but I can try to find the study if you're really interested.) One major consequence of these different living styles is the difference between male gorillas and male chimps. Male gorillas are much larger than the females, with large canine teeth, but hardly visible testicles. While male chimps are usually larger than females (sometimes a large female is bigger than a small male!), the difference isn't as big, their canines aren't as large, but they have very large testicles. This is because male gorillas compete to get a group of females (with their large size and big teeth), but once they have a group, their sperm are pretty much assured to have no competition. In chimps, because many males are in one group together, they need large testicles to produce many sperm to compete with the other males'.

    Sorry if that was way too much information, I started to ramble a bit there 😉

    Wow! You're really an expert 😃 Not too much information at all! I knew about the difference in size between male and female gorillas (being more distinctive than for chimps), but everything else was new 😃
    I'm always happy to learn new stuff!
