Sure, you could just slap an “s” on the end of “bear” and people will know what you mean. But most animals actually have a unique name for their collective group. Though uncommon, these are all unique terms for animal groups.
Ambush

Tigers: Notoriously solitary, tigers don’t often travel in groups. So you may not ever have the chance to identify an “ambush” of tigers. And maybe that’s for the best.

Bask, Float

Crocodiles: Basically, what a croc does is what it’s called. So a bunch of crocodiles on land is a “bask” while a bunch in the water is a “float.”

Bloat, Thunder

Hippopotamus: Because everyone will look at you funny if you say “hippopotami,” you could call a group of hippos a “thunder.” Or if you’re mean, call them a “bloat.”

Boil, Kettle

Hawks: While in flight, call them a “kettle.” But when they’re circling for prey, a group of hawks is a full-on “boil.”

Pheasant: Before it’s riddled with five shot, a pheasant in a group is part of a “bouquet.”

Ferrets: If you see more than one ferret, you’re looking at a “business.” And if you live near a city, it’s also a “problem.”

Cauldron

Bats: When the sky goes dark with a load of bats, you’ve got a “cauldron.” You may also want to head indoors.

Chain

Bobolinks: Believe it or not, a group of bobolinks is a “chain.” And to answer your next question, a bobolink is a small blackbird found in North and South America. It’s also the sole member of the genus Dolichonyx – but you probably already knew that.

Charm

Goldfinch: If you see a bunch of goldfinches, it could be your lucky day; that’s a “charm.”

Crash, Stubbornness

Rhinos: Of course you could say a “stubbornness” of rhinos and be correct. But a “crash” of rhinoceroses sounds so much cooler.

Deceit

Lapwings: If you hear a shrill, wailing cry, then note a crest and irregular wingbeat, you’ve got yourself a lapwing. And if you see bunch more, that’s a “deceit.”

Drift

Pigs: Typically, a “drift” refers to a group of young wild pigs.
Exaltation

Larks: Poems and songs have been written about the lark. So it’s not surprise that a group is called an “exaltation.”

Fever

Stingrays: During migration, hundreds of rays fly though the water, almost like a flock of birds. That’s a “fever.”

Labor

Moles: You may not ever see enough at one time to use the term, but a bunch of moles are a “labor.” That’s fitting considering their lives mostly consist of blindly chewing tunnels through the Earth.

Leap

Leopards: A solitary beast by nature, it’s rare to witness a “leap.” And because a leopard can vault 20 feet horizontally and has a 10-foot vertical, it’s a fair title.

Murder

Crows: To our knowledge, Alfred Hitchcock had nothing to do with this one. When you see hundreds of crows swarming in the sky or cawing from a tree, that’s a “murder.”

Mutation

Thrushes: It may seem an odd term, but the “mutation” of thrushes may derive from an apocryphal belief that thrushes shed their old legs at maturity and grew new ones. No, they do not.

Obstinacy

Bison/Buffalo: Honk, holler, wave – if you’ve ever encountered a group of bison blocking a road, you know that “obstinacy” is an appropriate name.
Ostentation

Peacocks: “Ostentation” suffices for a group of peacocks because “OMG, look at us, we’re FABULOUS!” doesn’t quite roll off the tongue.

Pandemonium

Parrots: If you’re surrounded by parrots, it’s literally “pandemonium.”

Turtledoves: On the second day of Christmas, your true love gave you a “pitying” of turtledoves.

Posse, Gang

Turkeys: The Sharks and the Jets aren’t the only posses or gangs. That also works for a bunch of gobblers.
Prickle

Porcupines: Whether or not you see a “prickle” of porcupines, just say it a few times. It’ll make you smile.

Quiver

Cobras: If you look around spot a bunch of cobras, you could say, “I see a quiver.” Or, you could just say, “AAAAAHHHHH!”

Rhumba

Rattlesnakes: It’s definitely not common, but “rhumba” is a known term for a group of rattlers. And no, they will do nothing to clean your floor.

Stand, Flamboyance

Flamingoes: “Stand” is far more common than “flamboyance” when referring to flamingoes. But who doesn’t want to say, “Look at that flamboyance of flamingoes!”

Tower

Giraffes: Now you know a group of giraffes is a “tower.” But do you know whether their tongues are red or black?
Photo credit: Luca Galuzzi
Troubling

Goldfish: Whether they’re pets or delicious cheddary snacks, if you’ve got too many goldfish it’s literally “troubling.”
Photo credit: Randen Pederson
Venue, Volt

Vultures: In flight, vultures are referred to as a “venue” or “volt.” But when they’re feeding on a carcass, that’s a “wake.” Creepy.

Wisdom

Wombats: Yes, a “wisdom” refers to a group of wombats. Now repeat after me: “I wuv a wisdom of wombats.”
Photo credit: JJ Harrison
Zeal, Dazzle

Zebras: There are myriad theories as to the purpose of a zebra’s stripes. Camouflage, insect repellent, and temperature control have all been postulated. But one thing is for certain, in a group, they’re a “zeal” or a “dazzle.”
