Parrots are very intelligent birds, and they can even learn how to talk. Let’s find out how to train a parrot to say words.
Parrots are popular pets. They are social and intelligent birds. They have the ability to mimic (模仿) human speech and we can teach them to talk!
Training your parrot
Put your parrot’s cage in a calm and quiet place.
Hold a treat in front of the bird and begin with a simple word like “hello”. Look at your bird and say “hello” in a bright and positive voice. Repeat the same word multiple times.
When your parrot starts making a sound like “hello”, give it lots of praise and a treat. Say the word back to it in an excited and loud voice.
When your parrot can say “hello”, move on to teaching it the next new word!
Read the article about how to teach parrots to talk and correct the statements.
Teaching your parrot to talk
Things to bear in mind
Choose the right time to train your parrot. If the bird looks tired or not interested, leave it alone.
Keep your training sessions short. When your parrot starts looking away from you or cleaning its feathers (羽毛), it is time to stop.
Only give your parrot a treat when it makes a sound similar to the word you are trying to teach.
Be patient. Give your parrot enough time to learn to say a word clearly.
Teaching your parrot takes time. Don’t be disappointed if your parrot doesn’t speak at first. One day, it may surprise you with a bright and breezy (轻松愉快的) “Hello!”

背景知识
鹦鹉能够模仿人类说话，主要与其独特的生理结构、听觉感知能力以及后天学习行为密切相关，具体原因可从以下三个核心方面解释：
一、关键生理基础：独特的发声器官
特殊的鸣管结构：鸟类的发声器官是“鸣管”（位于气管与支气管交界处），鹦鹉的鸣管周围附着大量灵活的肌肉，且鸣管分为左右两部分，可独立振动发声。这种结构使其能精准控制气流和振动频率，模拟出人类语言中复杂的音调、音色和节奏。
灵活的舌部与口腔：鹦鹉的舌头厚实、多肉且极具灵活性，类似人类舌头的功能。它能通过调整舌位、口腔形状配合鸣管振动，进一步细化声音细节，让模仿的语言更接近人类发音。
二、听觉与认知能力：精准的声音捕捉与记忆
鹦鹉具备强大的听觉分辨和声音记忆能力，为模仿提供 “软件支持”：
敏锐的听觉辨识：鹦鹉能清晰区分人类语言中细微的音高、声调变化（如汉语的四声、英语的重音），这使其能精准捕捉目标声音的特征。
长期声音记忆：它们的大脑中存在与声音学习相关的特殊脑区（如“核心鸣唱系统”），能将听到的声音信息储存并反复调取，通过不断练习调整发声，最终实现对人类语言的模仿。
三、行为动机：社交与生存需求驱动
鹦鹉的模仿行为并非“无目的的学舌”，而是受社交本能和后天互动驱动：
社交联结需求：鹦鹉是高度社会化的鸟类，在野外通过鸣叫与同类沟通。当它们与人类共同生活时，会将人类视为“群体成员”，模仿人类语言是其表达亲近、寻求关注或融入群体的方式。
后天强化学习：当鹦鹉模仿人类说话后，若得到主人的奖励（如食物、抚摸、回应），这种正向反馈会强化其模仿行为，使其更主动地重复和学习新的语言片段。
What animal would you like to keep as a pet In this project, you are going to make a class pet booklet.
Making a pet booklet
Step 1
Discuss and choose an animal that would make an interesting pet.
Step 2
Research key information about the animal and make notes. Use the following questions to help you.
Why do people like to keep this pet
How should people take care of it
What is your experience of keeping this type of pet
Step 3
Each group writes a page for the animal. Organize the information into sections and choose the most important or interesting facts for each section. Then find pictures or create your own. You may refer to the example below.
Step 4
Collect the pages from the different groups and make a class pet booklet. Write a contents page and design a cover.
我们可以通过一个人对待动物的方式，来判断他的内心。

When your parrot can say “hello”, move on to teaching it the next new word!
佳句回顾
3. 如果这只鸟看起来很疲惫或没兴趣，就别打扰它。
__________________________________________________________________________________________________
4. 只有当你的鹦鹉发出与你试图教的单词相似的声音时，才给它喂食奖励。

If the bird looks tired or not interested, leave it alone.
Only give your parrot a treat when it makes a sound similar to the word you are trying to teach.
