A new viewpoint on antlers reveals the evolutionary history of deer (Cervidae, Mammalia)
fullview recommended!
something i've wanted to do for a while now. i've scoured the internet for something like this and can't find anything that compares all the different types of antlers together. except one recent study on their evolution, which is also very interesting on its own! i simplified it to provide a visual reference, while still trying to be scientifically accurate. some things differ between this and trophy scoring terminology like where the beam is and whatnot, so if something looks weird that's why.
small additional note, this study and others provide a lot of evidence that eld's deer should be in their own genus as it doesn't appear similar enough to barasingha and schomburgk's deer. however this doesn't seem to be adapted anywhere yet, so they're still in Rucervus for this guide.
A similar type of transgender is found among Mule Deer, where the animals are known as CACTUS BUCKS owing to the distinctive shape of their antlers (which sometimes have elaborate spikes, prongs, and asymmetrical growths).

Mount Rainier National Park is a park full of sounds. Park researchers are constantly listening to the mountain using soundscape stations. Audio recording is a good way to track animal populations as well as geologic sounds like glacial movements and seasonal debris flows. Sometimes the animals even listen to us. On World Listening Day we invite you to listen with us and tell us what you hear.
Recordings from our listening stations are available on our website at https://go.nps.gov/1v7ltk.

Female Mule Deer also sometimes mount each other when in heat; in addition, some does court other females using a chasing sequence known as RUSH COURTSHIP.

All of these are black-tailed deer.
Notes: I've never seen this many deer just hanging out and not caring about people. They were so close I could touch them if I wanted. None of the bucks were aggressive; they just stood around and watched me take pictures. There were plenty of acorn woodpeckers around too, I just wasn't too focused on them.
During most of the year, White-tailed and Mule Deer live in sex-segregated groups: females form groups with other does and their offspring, while males (bucks) live in "bachelor" groups on their own.

Mama had twins again this year. I think I caught them this morning just hours after they were born (in my yard?!?) given that the babies are very scrawny, she was licking them a bunch, and they still had umbilical cord hanging.
Don't worry. I was just hanging out my window taking pictures of her and the babies. She's generally figured out that I say hi, but won't hurt her over the last couple years.
Gender-mixing Deer that are fertile (almost always genetically female) are usually heterosexual (i.e., they mate with genetic males), while nonfertile transgendered Deer (e.g., velvet-horns) are probably asexual or associate only with other transgendered deer.
