The main reasons why parrots cannot be kept casually are as follows. First of all, parrots are highly intelligent birds that need appropriate environmental stimulation and psychological needs to be met. If the breeding environment is monotonous and lacks appropriate toys and activity space, parrots can easily become bored and depressed, leading to abnormal behavior or emotional problems. Secondly, parrots need to receive a suitable diet and nutritional supply. Incorrect eating habits may lead to malnutrition or obesity in parrots, affecting their health and lifespan. In addition, parrots also need appropriate socialization and communication. If they are lonely for a long time and lack human interaction, it can easily lead to emotional problems and abnormal behavior. Finally, the breeding and feeding of parrots requires certain professional knowledge and experience, including correct feeding methods, disease prevention and control, etc. If the breeder lacks relevant knowledge and skills, the parrot's needs may not be met, affecting its health and happiness
