The Main Duo
- Heterosexual Life-Partners: They have been best friends since college and still spend most of their time together.
- Odd Couple: Tuca, a devil-may-care, bombastic and sexually liberated toucan shared an apartment with button-up, quiet and shy Bertie.
- Red Oni, Blue Oni: Tuca is the wild, rambunctious, confident red oni to Bertie's anxious and shy blue oni.
- Tomboy and Girly Girl: Tuca is gregarious, outgoing, and enjoys partying at the club, while Bertie is soft-spoken and has traditionally feminine interests such as baking and interior design.
- True Companions: Tuca is always helping Bertie in situations that require her to be more assertive, while Bertie, in turn, helps Tuca in situations that require her to be more focused. Even after their first big fight where they agree to spend some time apart, they clearly love one another too much to keep friction between them and are seen having fun and crying together mere hours after they see each other for the first time in days.
A cocky and carefree Toco toucan. She is in her 30's and living on her own after her roommate Bertie moves downstairs.
- Afraid of Doctors: Due to the trauma of being in the hospital when her mother died after a terrible car accident, Tuca doesnt trust doctors at all. She refuses to go to the hospital to get a painful lump in her side looked at and only ends up going when she passes out from pain and is brought there while unconscious.
- The Alcoholic: Recovering alcoholic. She's revealed to have had several relapses and at least one near-death experience from alcohol poisoning, but is sober when the show starts.
- Awesome, but Impractical: As shown in "The Promotion," Tuca does have skills, including in landscaping and building things, but she doesn't seem to know how to use them in ways that are both useful or can be made into sustainable careers (few people have use for a chest of drawers to store food for sandwiches).
- Big Eater: Nearly every scene depicts her eating something in large quantities.
- Bi the Way: She goes on a date with a guy working at a deli and most of her online clients are men, but she once kissed a female singer, some of her secret crushes are shown to be female and she shows interest in Coach Maple. She also blushes when Bertie kisses her on the cheek in "SweetBeak."
- Blithe Spirit: How she often helps Bertie with her problems. Due to being so responsible and anxiety-ridden, Bertie often feels like a situation is hopeless or can only be done a certain way. Tuca comes in and does whatever she wants with tons of confidence and swagger, solving problems in unconventional ways.
- Dark and Troubled Past: She lost her mother in a car wreck at a young age and became estranged from her surviving family as a result. She's also a recovering alcoholic, having repeatedly tried to go sober after a near death experience from alcohol poisoning in college.
- Extreme Omnivore: In one scene, ravenous for takeout, she first consumes the dumplings inside the Styrofoam box, and then gulps the box itself.
- The Gadfly: Pretty much her entire character. Whether it's the right time or not, Tuca will always do what she wants at any moment, even if (sometimes especially if) it makes others uncomfortable. It's not always without a point, often blurring it with Stealth Mentor and The Wonka.
- Genki Girl: An adult version. Tuca is very cheerful and loud most of the time.
- Grew a Spine: When Talulah insults Tuca's late mother, Tuca finally stands up to her, tearing up the check that Talulah wrote to her.
- Hard-Drinking Party Girl: Used to be one, which has resulted in at least one alcohol poisoning incident. While she still likes to party, she's been adamant about sticking to her sobriety since she stopped drinking six months before the events of the first season.
- Hidden Depths: She's revealed to be somewhat self conscious about her body image (mostly her thighs) and what Bertie thinks of her. Shes also very adamant about sticking to her current sobriety.
- Inferiority Superiority Complex: Downplayed. Tuca is every bit as confident as she seems day-to-day, but fears abandonment and has (well hidden) Weight Woe.
- Internalized Categorism: It's implied that Tuca has internalized her Aunt Talulah's emotionally abusive comments that she's a lazy, scatter-brained moocher who will never amount to anything.
- Jerk with a Heart of Gold: Tuca is loud, abrasive and tends to speak before she thinks, but clearly cares about her best friend Bertie.
- Large Ham: Tuca is not afraid to speak her mind whether people like it or not.
- Ms. Fanservice: She has a very curvaceous figure and her tush is drawn in heavy detail. We even see her topless on occasion. In her case, it's more an act of self-confidence rather than being attractive to men.
- No Indoor Voice: Tends to speak in shouts.
- One Head Taller: Than Bertie.
- Parental Abandonment: Tuca's mother raised her and her siblings before tragically dying in a car accident, and she mentions that her father walked out on the family.
- Relative Button: Do not insult her mother.
- Really Gets Around: Prior to the events of the series, she's had many sexcapades either screwing or making out with various partners, male and female.
- Recovered Addict: Well, "Recovering" Addict. She's been sober for six months and wants to keep it that way.
- She's Got Legs: "A toucan woman with strong legs".
- Tank-Top Tomboy: Her usual outfit. While also wearing Short Shorts.
- The Teetotaler: You'd expect her to fit into Hard-Drinking Party Girl territory, given her personality, but after a near-death experience in college and several relapses, she's decided that sober living is worth the effort.
- Trademark Favorite Food: While she generally eats a lot, she seems to have a preference for cold cuts.
- Trash of the Titans: Her apartment is littered with garbage, mainly half-finished containers of food. She works on fixing this in first season finale.
- Weight Woe: While its very well hidden, Tuca is self-conscious about her thick thighs.
Roberta "Bertie" Songthrush
An anxious and day-dreamy song thrush who used to live with her roommate with Tuca.
- A Date with Rosie Palms: At the end of "Plumage", Bertie furtively masturbates in the bathroom at Pastry Pete's bakery after Pete, whom she has a huge crush on, gets a little too close to her during her apprenticeship. It turns out to be an early hint of her psycho-sexual troubles.
- Afraid Of Lightning: "The New Bird" mentions that she hides during thunderstorms.
- Beware the Nice Ones: Is generally soft spoken and polite and dislikes confrontation, but can and will be assertive when she reaches her limits.
- Broken Pedestal: Becomes one to Dakota after the latter finds out the hard way that Bertie never told her about Pastry Pete's true nature.Dakota: I looked up to you...
- Commitment Issues: Bertie is very glad to have a steady boyfriend and is the first time she has reached a stage of a relationship in which they're living together, but she's also terrified of going any further than that. Even though she's aware of the fact they may move to a bigger house together eventually, when the opportunity comes up, she freezes up and makes them lose the house, and when having to face troubles, she just vanishes for a week from his life.
- Cloudcuckoolander's Minder: Uptight yet down to earth, Bertie often tries to reign in Tuca's flights of fancy without much success. Of course, this is only when they interfere with her life or cross a line, as she often needs Tuca's advice — and in one instance, argues against buying a house she doesn't want to commit to by claiming Tuca needs her. Deconstructed, as the show also showcases multiple instances where this is a strain on Bertie, and being there for Tuca often comes at the expense of Bertie's personal and professional life.
- Dark and Troubled Past: Her anxiety issues are at least partially the result of being taken advantage of sexually as a child by a camp lifeguard, which traumatized her enough to abandon her love of swimming.
- Ghost in the Machine: In "The Open House", we see the inside of Bertie's brain as she examines Pastry Pete, which contains two miniature versions of Bertie herself pacing around and seeing the world through Bertie's eyeballs.
- Neat Freak: She keeps her apartment immaculate, which is a full-time job considering she's best friends with Tuca.
- Nervous Wreck: Bertie clearly suffers from anxiety.
- Poor Man's Porn: While she admits that it's not technically porn, Bertie gets turned on by romantic BBC shows, largely because of how chaste they are.
- The Perfectionist: She tends to fixate on doing everything perfectly from her office job as a data analyst, to her side hustle as a baker, to her sex life with Speckle.
- Rape as Backstory: Bertie reveals in "The Jelly Lakes" that she was molested by a lifeguard when she was twelve, and that it's a key factor to her anxiety.
- Seldom-Seen Species: Bertie is specified as a song thrush.
- Shrinking Violet: Downplayed. Bertie isn't stuck-up, but prefers to keep to herself and not make a big deal of everything (that is, to not talk about openly). It's usually Tuca who often has to speak for her, whether she wants it or not.
- Species Surname: Her last name is "Songthrush".
- Sweater Girl: Contrasting Tuca's Tank-Top Tomboy.
- Trademark Favorite Food: She's a very light eater in contrast to Tuca and we never actually see her digging into her own pastries, but she's got a special love for spicy chips.
Bertie's architect boyfriend, a European robin. Bertie moves in with him at the beginning of the series.
- Alcohol-Induced Idiocy: After a few drinks at Talulah's house, he puts on a see-through shirt. During the drive home, Tuca notices that he's not wearing pants, to which he replies that he will never wear pants again.
- Anthropomorphic Food: Not him, but his grandmother that was turned to a cake and live in his guts (It's complicated.)
- Ambiguously Bi: He stumbles upon Tuca's sexual virtual chatroom/MMO job and plays it, thinking it's some kind of fighting game. He pieces it together a few moments later... and is later shown still playing it and gleefully "showing off" for some other players.
- Crouching Moron, Hidden Badass: Rarely in evidence, but he does manage to stop a rampaging jaguar by simply staring it down and firmly telling it to stop.
- Dogged Nice Guy: Deconstruction. At first, he seems to just go along with whatever Bertie wants to be with her, including dealing with Tuca's odd interferences in their relationship, but he eventually gets fed up of it when Bertie is shown to be as dysfunctional as Tuca and prone to leave the fall out on him. This includes making him lose their dream house because she couldn't commit to him.
- Encyclopaedic Knowledge: Of experimental architecture, as he reveals in "Plumage".
- Incredibly Lame Fun: His favorite snacks include plain chips and his idea of kinky porn is a couple moving in together and having respectful, consensual missionary sex.
- Only Sane Man: He's usually the last to get in on the shenanigans Tuca ropes Bertie into.
Coach Meredith Maple
- Amazonian Beauty: She is very muscular and quite pretty despite her older age. Tuca pretty much admits she finds her hot.
- Badass Biker: She owns a bike with a pretty sweet paint job resembling a bird's head, and she's pretty reckless while driving it.
- Badass Bisexual: Currently married with a female barn owl after becoming a widow to a male ass, she is an apt swimmer and can take down a giant crab.
- Bi the Way: She was married to a male ass back when Bertie was a kid, but after he died, she remarried a female barn owl and remembers of her husband fondly.
- Butch Lesbian: She's very big and burly looking, typical of this archetype.
- Cool Teacher: Bertie's cool swimming coach, back when she was a kid. By all means, Coach Maple is a caring and supporting mentor.
- Even the Girls Want Her: A given, since she is openly bisexual and married with another woman. Tuca says Pat is lucky she gets to make out with her.
- Knife Nut: Before her identity is revealed, Tuca speculates she might have a butterfly knife. Indeed, as she's leaving the mall she is carrying a shopping bag with a picture of a knife with butterfly wings on it, implying that Tuca was right and Coach Maple actually does carry knives.
- Seldom-Seen Species: She's a red-crested turaco.
- Big Beautiful Woman: She's quite plump, and as Tuca notes, "gets to make out with coach Maple whenever she wants."
- Birds of a Feather: Although she's more soft-spoken than Tuca, they possess the same joie de vivre and quickly strike up a bond.
- Don't Explain the Joke: She loves to make jokes, laugh at them, then clarify whatever the truth of the matter happens to be.
- Ink-Suit Actor: Resembles her actress Isabella Rossellini in both physique and facial features.
- The Owl-Knowing One: Makes beautiful eggshell dioramas and is generally very patient and sensible, dispensing gentle wisdom about craftsmanship.
- Verbal Tic: She hoots whenever she laughs, which is often.
- Cool Old Lady: Talulah when she finally appears in person. She's every inch an Older and Wiser Tuca, with money and class, the biggest difference being her drinking to Tuca's sobriety. Subverted HARD once enough drink brings out her true personality, revealing a bitter, abusive Rich Bitch who controls Tuca through her money and shames her for every part of her life. And Tuca doesn't even protest. She finally crosses the line when she dismisses Tuca's mother as 'worthless' for ostensibly having never accomplished anything in her life beyond raising several children to adulthood.
- Fatal Flaw:
- Pride. She sees herself as superior to Tuca and Tuca's late mother because she made millions while they lived in poverty. Her pride drives her to emotionally abuse Tuca, driving her away.
- Greed. Despite being a wealthy businesswoman, Talulah never lifted her relatives out of poverty. The check she writes Tuca in "Plumage" is a measly $1,250.
- I Was Quite a Looker: She was tall, elegant, and stunning in her prime. She technically still is a looker, her elegance and confidence in her looks completely undiminished; it's her personality that's ugly.
- Jerkass: She's emotionally abusive to Tuca, especially after she's had a few too many drinks.
- Lady Drunk: In contrast to her niece who is The Teetotaler. Catches up to her when she gets cirrhosis by the season finale and gets stuck in the hospital.
- Really Gets Around: She's been married to at least a dozen wealthy men.
- Rich Bitch: Very wealthy, very arrogant, and very emotionally abusive to Tuca.
- Uncanny Family Resemblance: Looks very much like her niece.
BruceA perverted old vulture who lives one floor below Bertie.
- The Alcoholic: Is often seen with a beer bottle in a paper bag.
- Chivalrous Pervert: Downplayed. While he's an absolute creep, he doesn't seem to do much worse than make gross flirty comments. Even Bertie isn't afraid of him.
- Dirty Old Man: Appears to be significantly older than our protagonists and is almost always trying to flirt with them.
- A Date with Rosie Palms: When Tuca tells him to "beat it," he tells her it'll be for the third time today as he stretches his shoulder.
- Visual Pun: He's a literal and figurative vulture who preys upon attractive women.
Dapper T. DogTuca's upstairs neighbor, a tall, theatrical dog.
- All Gays Love Theater: There are framed Playbills all over his apartment, and he's established as Camp Gay from his first appearance.
- Butt-Monkey: He's profoundly unlucky.
- Camp Gay: Effeminate, kerchief-clad, and fond of theater.
- Exactly What It Says on the Tin: He's dapper and also a dog.
- Foil: Humorously enough, to Bernard the butler. Both are dogs with sophisticated air around them, but while it's genuine for Dapper, Bernard is quite prone to breaking out into actual dog behavior.
- Howl of Sorrow: Prone to breaking out into these whenever he's particularly distraught.
- Interspecies Romance: In his first scene, he's dramatically pining for a human named Henry.
- Sesquipedalian Loquaciousness: Speaks this way at every opportunity.
DracaA plant woman who lives in apartment 5B. She's cool and mysterious.
- Asshole Victim: His chauvinism almost always results in some Laser-Guided Karma.
- Character Development: He eventually starts dating the HR lady and at least trying to be less of a raging douche, with patchy progress. The last we see of him in the series, he's eating one of Bertie's sweet rolls and then sweeping HR Lady into a kiss.
- Hate Sink: Unlike Pete, he isn't really that threatening, but that doesn't make him any less hateable.
- Jerkass: He steals Bertie's ideas, sexually harasses her and looks absolutely bored when she calls him out for it.
- Jerk with a Heart of Gold: Is trying to become this. Whether or not he's actually having any success kind of depends.
- Karma Houdini Warranty: Apparently, Dirk has been harassing women for a long time before Bertie finally called him out for it.
- Official Couple: Becomes one with HR Lady after the Time Skip.
- Straw Misogynist: Pretty clearly doesn't think of women as much more than things he can flirt and harass freely. Later Inverted on account of him going through Character Development.Dirk: As a man, it's so nice to finally have my voice heard, you know?
- Took a Level in Kindness: After the Time Skip, he's revealed to have realized his actions were awful, and is attempting to become a kinder person.
- Visual Pun: Dirk is a rooster - a literal cock, if you will.
- Benevolent Boss: He's clueless and doesn't take well to being shushed, but is a generally affable guy who treats his employees well and take Dirk's sexual harassment very seriously once he's made aware of it.
- Bitch in Sheep's Clothing: At first it seems like his stern nature comes off as just part of his job and Pete is an otherwise reasonable guy, but it's later revealed that he has no qualms using his success to prey upon female admirers and monopolize the entire baking industry in Birdtown.
- Everything Is Better With Penguins: Subverted with Pastry Pete. Bertie loves being his apprentice and crushes hard on him, but not so much when he tries to put the moves on a different, younger apprentice and even less so when she finds out he has a monopoly on any and all baking businesses in Birdtown.
- Mean Boss: At first it's downplayed, as he's harsh and a bit condescending but still attractive and a helpful mentor to Bertie. Eventually Bertie sees him as the disturbingly flirtatious, controlling jerk he is, and after she quits, he guilt-trips her, stonewalls her new business, and even threatens her physically.
Baker BarbThe assistant of Pastry Pete.
- Chekhov's Gunman: She confirms in the final episode of season one that Pete has been denying Bertie territory within the town.
- The Quiet One: She's not a very talkative bird. Even when Bertie greets her in "Plumage", she doesn't return her greeting and continues working in silence. However...
- Suddenly Voiced: She finally speaks in the season one finale, "SweetBeak", where she informs Bertie to try selling her baked goods somewhere else, as Pastry Pete holds a monopoly on baked goods in Bird Town.
- Beware the Nice Ones: She is sweet, idealistic and slightly naive to the point of parody, but unlike Bertie, she stood up to Pete right away when he started harassing her and then she called out Bertie for not warning her about him.
- Country Mouse: The country to Bertie's city.
- Foil: Set up as one to Bertie. Bertie is nervous, Dakota is carefree, but they both work at Pastry Pete's and have similar personality beats, down to their coping mechanisms. Dakota snaps at Pete for sticking her face in a boiling pot for some sort of hazing ritual, while Bertie got turned on and masturbated earlier in the season when it happened to her.
- What Happened to the Mouse?: Dakota doesn't appear after her debut episode. Not even in "Sweet Beak" when news of Pete's sexual harassment gets spread, when it would make the most sense.
- Wide-Eyed Idealist: A very tongue-in-cheek version. She came to the city with two suitcases "full of socks" and looked towards everything she and Bertie did with fleeting optimism. She does, however, have her limits, and she snaps when Pete tries to act like a creep, and when she realizes Bertie never warned her.
