Final answer:
The phrase 'Sweet Is the Breath of Morn' metaphorically describes the freshness and beauty of morning, often associated with active and expressive animals like birds. It does not directly refer to reptiles, although reptiles, like snakes, have their own unique interactions with the morning air.
Step-by-step explanation:
The phrase 'Sweet Is the Breath of Morn' does not directly refer to reptiles; instead, it evokes the freshness of the morning and is more emblematic of creatures associated with the dawning day that exhibit vivacity and beauty. The provided references discuss a variety of animals, including insects, birds, and mammals, which exhibit the invigorated essence of the morning through their activities or characteristics.
One reference points to the concept of reptiles in relation to the sense of smell, mentioning how a snake flicks its tongue to capture scent molecules in the air. However, this action is a method of interacting with their environment, not a direct connection to the sentiment expressed by 'Sweet Is the Breath of Morn'. The focus is more on a general sense of arousal and the exotic and the wildness of nature.
Moreover, animals such as the lark with its 'wild' song or a fleet-footed gazelle capture the essence of the statement more fittingly by aligning with the theme of nature's awakening and the celebration of life and movement that are found in the soft light of the morning.
