What facts suggest that the old sparrow was very afraid of the dog? - in detail

The old sparrow's behavior provided several telling signs that it was extremely frightened of the dog. Firstly, its body language was indicative of acute fear: the bird's feathers were ruffled and not smooth as they usually are when relaxed. Additionally, the sparrow adopted a low, crouched position, attempting to make itself less visible—a common defensive posture in birds. The constant vigilance displayed by the old sparrow was also noteworthy; it kept its eyes fixed on the dog, unable to look away even for a moment, exhibiting a heightened state of alertness typical of creatures in grave danger. Moreover, the sparrow's proximity to the ground, seeking cover and safety under nearby shrubs or trees, further underscored its intense fear. The bird's avoidance strategy was another clear indicator: it repeatedly tried to distance itself from the dog, flying away as soon as possible and only returning when absolutely necessary, such as for food. These collective behaviors strongly suggest that the old sparrow harbored a profound fear of the dog.
