In a close-up nature photograph taken in midsummer, a small bird stands on the top branch of a dense emerald green pine tree. The pine tree has flourishing branches and leaves, and the details of the bird are clear. The background features a pure and cloudless deep blue sky. The composition is extremely simple, with the main subject prominent and the colors bright (green pine trees and blue sky), capturing a quiet and natural moment, conveying a fresh and vivid atmosphere, and shot with a telephoto lens, where the sky occupies 90% of the overall picture.
