Margaret

Margaret is a female red robin who works as a waitress in the coffee shop, across the street from the park. She's one of the few animal characters on the show that wears clothing. Mordecai has a large interest with her, and is always finding ways to make excuses to go to the coffee shop to see her. Margaret is voiced by Janie Haddad.

 * Feathers are red and white color (white feathers sometimes appear pinkish).
 * Beak is curved.
 * "Spot" on the side of her head is comma shaped and brownish.
 * She sports no stripes.

Cartoon Network Character Page Description
"This red breasted robin works as a waitress at the coffee shop across the street from the park. Mordecai has a huge crush on her and is always finding excuses to take coffee breaks when she's working."

Mordecai
Margaret is Mordecai's love interest, and is one of her best friends. Episodes that Margaret appear in are usually accompanied by a failed attempt by Mordecai to initiate a conversation, which proves to be an arduous task itself.

In Season One, they appear to be friends ever since Margaret's first appearance in Caffeinated Concert Tickets (possibly earlier). Much to Mordecai's dismay, Margaret seems to be totally oblivious toward Mordecai's interest on her, even showing off her other dates (one of which she dumped right away) in front of him.

In Season Two, the both of them start to develop more than just a friendship, albeit more haphazardly than needed (i.e. It's Time, Brain Eraser and Do Me A Solid). Despite the aforementioned "bumps on the road", the two keep their friendship intact. At this time, Margaret spends more time with Mordecai, mostly since she lacks any boyfriends in each episode, unlike Season One.

In Season Three, there are numerous times when the two appear much more closer than they normally are (i.e.Slam Dunk, Margaret calls Mordecai "hot", Camping Can Be Cool, when the two nearly held hands; Cruisin, where they did' hold hands, even if very briefly).

In the episode "Butt Dial" Margaret hears Mordecai's embarrassing message (in which he sings about her and how it would be if they were together) and surprisingly sets it as a ring tone for when Mordecai calls her. She also tells him that he'd better call her more often. This could imply that Margaret and Mordecai are possibly becoming more than friends.

Rigby
Margaret rarely interacts directly to Rigby, but in It's Time Rigby makes Margaret laugh, and almost manages to go to a movie with her.

Eileen
Margaret and Eileen are best friends the way Mordecai and Rigby are. She is close to Eileen and does solids for her all the time (Do Me A Solid). Margaret hopes for Eileen and Rigby to become closer.

Trivia

 * In Camping Can Be Cool, Margaret mentions that she attends a college in the City and also plans to quit her job at the Coffee Shop as soon as she graduates (much to Mordecai's chagrin).
 * Earlier in the same episode, she also mentions that she hasn't had a boyfriend for a while. The last time she has had a boyfriend was in Mordecai and the Rigbys (also one fake boyfriend in Cruisin').
 * Despite being described as a robin, Margaret has red plumage, which is odd since only male robins carry any red feathers in reality.
 * Margaret's car strongly resembles a 1982-1985 Honda Accord hatchback.
 * In Do Me A Solid and Cruisin', Margaret wears the same outfit.
 * In Do Me A Solid she mentions that her father used to bring her to play mini golf when she was a child.
 * In High Score Margaret hugs Mordecai after he and Rigby beat the world record of Broken Bonez.
 * In Butt Dial, it reveals that her phone password is "Daddy's girl".
 * In Do Me a Solid and Butt Dial, it shows that she has a close relationship with her father.
 * Originally, Margaret wasn't going to wear clothing like Mordecai. This was changed for unknown reasons.
