One morning, a student asked me: “Teacher, if a female cat is a ‘queen’, why isn’t a female dog a ‘princess’?” The question made the whole class laugh — and made me realise that English animal terminology is actually quite logical once you see the patterns. Some animals have completely different names for males and females (buck and doe, tom and queen), while others use the same base word with a gender marker (lion and lioness). This guide untangles those patterns so you understand not just the words, but the reasoning behind them.
Whether you’re reading a biology textbook, watching a nature documentary, writing about pets, or just curious about language patterns, knowing the gendered names for animals deepens your understanding of English. I’ve organized the vocabulary by animal type (mammals, birds, reptiles) so you see the structures that repeat across groups. Each entry includes example sentences showing how native speakers actually use these terms in conversation.
Key Takeaways
- Three naming systems exist: Some animals have completely different male/female names (buck/doe); others add a suffix like -ess (lion/lioness); others use a modifier (male sheep/female sheep).
- Young animals have age-specific names: Not all babies are called “babies” — a young horse is a foal, a young sheep is a lamb, a young cat is a kitten.
- Collective nouns describe groups: A “pride” of lions, a “murder” of crows, a “parliament” of owls — these terms are rooted in medieval tradition and poetry.
- Some gender terms are archaic: Words like “tom” (male cat), “queen” (female cat), or “bitch” (female dog) are correct but carry different formality levels in modern speech.
- Livestock and domestic animals have the most distinct terminology: Horses (stallion/mare), cattle (bull/cow), and birds (cock/hen) have the longest-standing, most specific terms.
The Three Systems of Animal Gender Terminology
English uses three main patterns to distinguish male and female animals:
- Completely different names: Buck and doe (deer), tom and queen (cats), boar and sow (pigs), cock and hen (chickens).
- Suffix addition (-ess, -ine, -a): Lion and lioness, actor and actress (used metaphorically for animals), prince and princess (in fables).
- Descriptive modifier: “Male elephant” and “female elephant,” “male dolphin” and “female dolphin” — when language hasn’t created distinct terms.
The most distinct terminology exists for animals humans have domesticated or hunted for centuries — horses, cattle, sheep, and poultry. Newer or less familiar animals simply use the modifier system.
Why these patterns exist: English borrowed gendered animal terms from Old English, Norse, and Latin. Livestock terminology (stallion, mare, sow, boar) comes from farming languages that needed to be precise about breeding. Wild animals got their terms centuries later, so they’re less standardized.
Farm and Domestic Animals
Domestic animals have the most established gender terminology in English because farmers and breeders needed precision for breeding programs.
Horses and Equines
| Generic Name | Male Name | Female Name | Young Name | Collective Noun |
|---|---|---|---|---|
| Horse | Stallion /ˈstæl.jən/ | Mare /meɪr/ | Foal /foʊl/ | String, team, herd |
| Donkey | Jack | Jenny | Foal or colt (male) / filly (female) | Herd |
| Zebra | Stallion | Mare | Foal | Herd, crossing, dazzle |
Example 1: The stallion pranced across the field while the mare watched over her foal.
Example 2: A string of horses was hitched to the wagon for the long journey.
Example 3: Jenny the donkey and her foal were inseparable.
Cattle and Bovines
| Generic | Male (Adult) | Female (Adult) | Young (Both Sexes) | Female (Young) | Collective |
|---|---|---|---|---|---|
| Cattle | Bull /bʊl/ | Cow /kaʊ/ | Calf /kæf/ or calves | Heifer (young cow) | Herd, drove |
| Buffalo | Bull | Cow | Calf | Heifer | Herd, buffalo |
| Yak | Bull | Cow | Calf | — | Herd |
Example: The farm’s dairy herd consisted of 40 cows and one bull, along with several heifers and calves.
Sheep and Goats
| Generic | Male (Adult) | Female (Adult) | Young | Collective Noun |
|---|---|---|---|---|
| Sheep | Ram /ræm/ | Ewe /juː/ | Lamb /læm/ | Flock, fold |
| Goat | Billy (or buck) | Nanny (or doe) | Kid /kɪd/ | Herd, tribe, flock |
Example 1: A flock of sheep grazed peacefully on the hillside, with the ram watching protectively over the lambs.
Example 2: The billy goat chased the nanny away from the hay pile, and their kids played nearby.
The “ewe” pronunciation trick: The word “ewe” (female sheep) sounds like “you” — not like “ewww.” Use that to remember it. Ewe = you (singular), ewes = yous (plural).
Pigs
| Generic | Male | Female | Young | Collective |
|---|---|---|---|---|
| Pig | Boar /bɔːr/ | Sow /saʊ/ | Piglet, suckling | Herd, drove, sounder |
| Hog | Boar | Sow | Piglet | Herd |
Example: The sow nursed her piglets while the boar rested in the mud.
Poultry and Birds
Poultry (domestic birds raised for meat, eggs, or feathers) have some of the clearest gender distinctions in English, partly because they’ve been domesticated for thousands of years.
Common Poultry
| Bird | Male | Female | Young | Group |
|---|---|---|---|---|
| Chicken | Rooster /ˈruːs.tər/ | Hen /hen/ | Chick /tʃɪk/ | Flock, brood |
| Duck | Drake /dreɪk/ | Duck | Duckling | Flock, paddling, raft |
| Goose | Gander /ˈgæn.dər/ | Goose | Gosling /ˈgɑːz.lɪŋ/ | Gaggle, skein |
| Turkey | Tom /tɑːm/ | Hen | Poult /poʊlt/ | Flock, rafter |
| Swan | Cob /kɑːb/ | Pen /pen/ | Signet /ˈsɪg.nət/ | Bevy, wedge |
Example 1: The farmer’s rooster crowed at dawn, waking the hens in the coop.
Example 2: A gaggle of geese flew overhead, their honking echoing across the valley.
Example 3: The pen (female swan) glided gracefully across the lake, followed by her cygnets.
Wild Birds with Gender Terms
- Cock and hen (pheasant, dove, sparrow)
- Male and female (crow, raven, hawk)
- Cock and hen (quail)
- Tiercel (male hawk, falcon) and falcon (female)
- Leopardess (female leopard — see section below)
Wild Mammals
Wild mammals use more varied terminology. Some have ancient English words; others rely on the -ess suffix; still others simply use “male” and “female.”
Carnivores (Cats, Dogs, Bears)
| Animal | Male | Female | Young | Collective |
|---|---|---|---|---|
| Lion | Lion | Lioness /ˌlaɪ.ənˈes/ | Cub | Pride |
| Tiger | Tiger | Tigress /ˈtaɪ.gres/ | Cub, whelp | Streak, ambush |
| Leopard | Leopard | Leopardess | Cub | Leap, lepe |
| Cat | Tom /tɑːm/ | Queen /kwiːn/ | Kitten | Clutter, glaring |
| Dog | Dog | Bitch /bɪtʃ/ | Puppy | Pack, couple, mute |
| Wolf | Wolf | She-wolf | Pup, whelp | Pack, rout |
| Bear | Boar | Sow | Cub | Sleuth, sloth |
Example 1: A pride of lions basked in the sun, with the male lion watching over the females and cubs.
Example 2: The tigress fiercely protected her cubs from approaching males.
Example 3: My tom cat and queen cat had a litter of kittens this spring.
Register note on “bitch”: This is the correct term for a female dog, but it is considered vulgar in modern English when used as a general term for women. Use it only when discussing dogs in technical or breeding contexts. Similar caution applies to other animal terms used as human insults.
Hoofed Animals and Primates
| Animal | Male | Female | Young | Collective |
|---|---|---|---|---|
| Deer | Stag, buck | Doe | Fawn | Herd, gang |
| Elk | Bull | Cow | Calf | Herd, gang |
| Moose | Bull | Cow | Calf | Herd |
| Giraffe | Bull | Cow | Calf | Herd, tower |
| Monkey | Male | Female | Infant, baby | Troop, barrel |
| Gorilla | Male, silverback | Female | Infant | Band, troop |
Example 1: The stag led the herd of deer across the meadow, with the doe and fawns following closely.
Example 2: A tower of giraffes grazed on the acacia trees in the African savanna.
Marine Mammals
| Animal | Male | Female | Young | Group |
|---|---|---|---|---|
| Whale | Bull | Cow | Calf | Pod, school |
| Dolphin | Bull | Cow | Calf, pup | Pod, school, herd |
| Seal | Bull | Cow | Pup | Colony, haul-out |
| Otter | Male | Female | Pup, kit | Float, raft |
| Walrus | Bull | Cow | Cub, pup | Herd, pod |
Example: A pod of dolphins swam alongside the boat, with a cow and her calf leading the group.
Reptiles and Amphibians
Reptiles (turtles, snakes, crocodiles) and amphibians (frogs, salamanders) typically use the “male/female” descriptor because they haven’t developed distinct gendered terms in English.
| Animal | Male Term | Female Term | Young Term |
|---|---|---|---|
| Snake | Male snake | Female snake | Hatchling, neonate |
| Turtle / Tortoise | Male turtle | Female turtle | Hatchling |
| Crocodile / Alligator | Male crocodile | Female crocodile | Hatchling |
| Frog | Male frog | Female frog | Tadpole |
| Lizard | Male lizard | Female lizard | Hatchling |
Insects
Insects use technical or descriptive terminology because most people don’t have regular conversations about gendered insects.
| Insect | Male | Female | Young / Transformation |
|---|---|---|---|
| Bee | Drone | Queen (reproductive), worker (female, sterile) | Larva |
| Ant | Male (dies after mating) | Queen (lays eggs), worker (female, sterile) | Larva |
| Butterfly | Male | Female | Caterpillar, chrysalis, pupa |
| Grasshopper / Cricket | Male | Female | Nymph |
| Fly / Mosquito | Male | Female | Larva, maggot (fly) |
Common Mistakes Learners Make
✗ Incorrect: “The lioness hunted alone while the lion stayed with the cubs.”
✓ Correct: “The lioness hunted with other females in the pride while the male lion stayed near the cubs.”
Why: In prides, female lions (lionesses) do most of the hunting; males protect the territory and cubs.
✗ Incorrect: “I have a horse and a female horse.”
✓ Correct: “I have a stallion and a mare.”
Why: Use the specific gendered terms when they exist — they’re clearer and more natural.
✗ Incorrect: “The duck is the male and the goose is the female.”
✓ Correct: “The drake is the male duck, and the goose is the female duck. A male goose is a gander.”
Why: “Duck” and “goose” are two different species, not male/female pairs. The gender terms are drake/duck and gander/goose.
✗ Incorrect: “We use tom for male dogs.”
✓ Correct: “We use tom for male cats; a male dog is just a dog, and a female is a bitch.”
Why: Each animal has its own gendered terminology. Tom is specific to cats.
Sample Dialogues
At a Farm
Farmer: Welcome to our dairy farm! Let me show you around.
Visitor: I see lots of cattle. Are they all females?
Farmer: Most of them. These are cows and heifers — that means adult females and young females. That large animal over there is our bull.
Visitor: And what about the little ones?
Farmer: Those are calves. Some will grow up to be cows, others will be steers — that’s a castrated male.
At a Zoo
Parent: Look, children — lions!
Child: Why does that one have a big hairy neck?
Parent: That’s the male lion. The ones without the mane are lionesses. Lions live in family groups called prides.
Child: Do the males hunt?
Parent: Mostly the females hunt. The males protect the pride from other lions.
Child: Cool! What are the baby lions called?
Parent: Cubs. Come, let’s watch the new cubs over there.

Frequently Asked Questions
Why do some animals have different male and female names while others don’t?
Animals that have been domesticated or hunted for centuries (cattle, horses, poultry) developed distinct gendered terms in English. Newer or less familiar animals simply use “male” and “female” because the language never created specific words. The gendering system reflects humanity’s historical relationship with animals.
Is it true that “bitch” means a female dog?
Yes, it is the correct technical term for a female dog. However, it’s considered vulgar when applied to women, so be careful about context. In dog-breeding or veterinary discussions, “bitch” is the standard term. In casual conversation about your female dog, many people say “female dog” or “girl” instead to avoid the double meaning.
What is the difference between a doe and a ewe?
A doe is a female deer. An ewe is a female sheep. Both are hoofed animals, but they’re different species entirely. A young doe is a fawn; a young ewe is a lamb. Remember: ewe sounds like “you” (singular) and refers specifically to sheep.
What’s the difference between “duck” and “drake,” and between “goose” and “gander”?
These are often confused because they sound similar. A drake is a male duck; a duck is a female duck. A gander is a male goose; a goose is a female goose. “Duck” and “goose” are two different bird species, not a male-female pair.
What is a baby lion called?
A baby lion is called a cub. Cubs (both male and female) stay with their mother and other females in the pride for 2-3 years before males are pushed out to form bachelor groups or find their own territory.
What is the term for a castrated male horse or cattle?
A castrated male horse is a gelding. A castrated male cattle is a steer. Castration is done to reduce aggression and make animals easier to handle in farming and ranching.
