(writing in progress)
The existence of a caudal mane – something I first noticed while dissecting giraffes in the ‘eighties in Kenya - does not seem to be acknowledged in the literature, even today.
However, its existence is
Many photos show the existence of a caudal mane in Giraffa tippelskirchi. This is perhaps most noticeable in infants. However, it remains in adult females.
The following is possibly the clearest illustration available on the Web: https://www.alamy.com/stock-photo-young-kenyan-giraffe-in-the-wide-open-plains-of-the-serengeti-in-the-23826900.html?imageid=F78E4FE7-8E63-4281-A5CD-57FB3C26FE21&p=17446&pn=5&searchId=c0f0098fc9003bb0b52e4512cf828bb9&searchtype=0.
Giraffa giraffa is so closely related to G. tippelskirchi that the two are possibly the same species. However, the caudal mane is so poorly-developed in G. giraffa that it is hardly visible.
The difference between G. tippelskirchi and G. giraffa, w.r.t. the caudal mane, is paralleled by the occipital horn-tufts (https://www.alamy.com/portrait-of-giraffe-against-blue-sky-in-maasai-mara-image243569073.html?imageid=03FBCA44-8D47-4955-AFCC-C169A4AAB466&p=296441&pn=6&searchId=add6a0dd1f4d3cd73b2d8fa8f8cde388&searchtype=0).
The caudal mane is poorly-developed in Giraffa camelopardalis, in contrast to G. tippelskirchi - despite the proximity of the distributions in Kenya.
I have yet to see any evidence of a caudal mane in Giraffa reticulata.
By the way, please note that the spots on the stalk of the tail are asymmetrical about the mid-line, i.e. comparing left to right.

The following is an unusual illustration of the pedal flag in Giraffa tippelskirchi:

The following is a particularly clear illustration of the pedal flag in infants of Giraffa tippelskirchi:

It is odd that a tail-mane occurs also in infants of Equus quagga boehmi, whixhncoexists with G. tippelskirchi:
