A live cow
Outside of a zoo, maybe American Avocet or Painted Bunting
Probably a Takahē in New Zealand but in captivity.
In the wild I’ve seen kiwi, kea, Kākā. I took a trip to mana island in the late 90’s, the kiwi were just wandering around during the day…
I’ve never seen the takahē.
Wolverine.
I saw a lynx cat in th3 backyard of a place I was staying at in Washington it was very cool.
Panay monitor lizard.
My buddy was trapping monitor lizards for us to eat and we caught one of those. He recognized it and told me that they were endangered.
We did NOT eat it. It went back into the forest, unharmed.
Polar Bear on the Hudson Bay coast in northern Ontario.
I’m Indigenous and I’ve gone hunting and trapping with my relatives a few times in my life. On one of those trips we happened on a polar bear on the mud flats of the bay during the late autumn. We drove by in our freighter canoe (a very large oversized canoe with a 60 HP outboard motor) and the bear swam near us and then walked by a few hundred feet away. It wasn’t afraid but we were. We watched for a while and then fired rifle shot into the mud next to it to scare it away. From the moment it started to run to the point it disappeared as a speck on the horizon was about a minute or two. I went up later to look at the prints and the clay mud looked like a tractor had driven over it. I couldn’t believe how fast it could move on the mud. I quickly sank in my boots and could barely walk around.
One paw print was about the size of my head. I never left camp without someone nearby or a rifle in my hands.
I guess nobody can tell how big they are from photos. There’s never someone standing next to them for comparison.
In the wild: Florida scrub jay. key deer. carracarra. Indigo racer. I don’t know how to determine what is rarest. There are a lot I have seen.
There was a stray firefly at my house one night. Like, singular. We’re not even near their habitat, so I don’t know what’s up with that.
A panda at Singapore zoo.
Either a black stork, a least weasel (actually pretty common, but difficult auf to see around here), Cerambyx cerdo (probably not as rare as most regulating bodies think), a Eurasian eagle owl (rare around Germany) or felis silvestris
Tarsier
In captivity: probably red wolves, or some critically endangered birds at the National Aviary.
In the wild: probably some plants endemic to Catalina Island.
Saw a fishercat in an industrial area not far from a large swath of floodplain and high voltage transmission lines. So there was a lot of territory for it nearby. Looks like a tall badger. Apparently pretty rare. Was walking around 18 wheeler trucks in motion like it owned the place, peeking around the dumpsters most likely looking for the young raccoons that hang around.
Giant Panda and Red Panda maybe.
