Frida Kahlo put so many symbolic creatures in this painting. She was not painting a realistic scene but using these symbolic elements to express her feelings. A bird is often symbolize freedom and life. Especially hummingbird which is colorful and always hovering above flowers. But in this painting the humming bird is black and lifeless. This might be a symbol of Frida herself. This is a painting about her suffering.
Frida Kahlo's work was influenced by traumatic physical and psychological events from her childhood and early adulthood, including a crippling accident and the infidelity of her husband. In addition to personal issues, Kahlo's often brooding and introspective subject matter also deals with questions of national identity.
