まだ一口も食べてないクッキーを鳥に取られたって英語でなんて言うの？

A cookie in the USA is the same as a biscuit in the UK.

In the UK cookies are usually known as biscuits although the word cookie is understood.This scenario is not uncommon although you could give possibly more detail if you are able to identify the species of bird. The most common bird thief in the UK is the seagull.

"I was walking home and the birds flew down and ate my cookie". or "the bird snatched the cookie from my hand". or "the birds were circling like scavengers, about to swipe my cookie".

To 'snatch' is to grab something in a rude and unexpected way. It is similar to 'steal'. You could use either and both would be correct. We use the phrase 'right out of my hand' when we are talking about losing something, or something being snatched away from you. "He stole my phone right out of my hand!"

*A bird snatched a cookie from my hand as I was about to take my first bite. *Before I could take my first bite, a bird snatched a cookie from my hand. -snatch means to quickly take away something. Example Sentences: Her bag was snatched by a thief in the market. The beggar snatched the food from his hands.

When you want to explain that you were about to eat a cookie you had in hand, and a bird charged at you and snatched it out of your hand; then you may explain this in the following ways: -A bird came flying at my and took the cookie I was about to eat out of my hand -A bird came flying and took the cookie out of my hand. I hadn't even had a bite yet.

"A bird swooped down and took my cookie from my hand! I had not yet taken a bite." This statement adds a dramatic effect to your story. Swooped indicates the bird flew down and took the cookie without you being aware. It then indicates that you did not have the satisfaction of eating the delicious cookie as the bird took it before you could. "Before I had even taken a bite from my cookie, a bird flew down and took it right out of my hand!'" - This statement places emphasis on the fact you had not yet eaten your cookie. It then explains why, giving an adventurous account of how the bird flew down from the sky and took the cookie directly out of your hand. Not from your plate but from your fingertips indicating that the bird was not fearful of you but quite cheeky!

"A bird flew at me and took my uneaten cookie from my hand" This sentence is implying that a bird 'flew' (to fly in past tense) at ones self and 'took' (to take,grab something from someone, again in past tense) a 'cookie' (a very popular snack often called a biscuit in the UK). If someone takes something from you unwillingly you can also say it was stolen from you. ex. "A bird stole the cookie from my hand".
