The lyrics to I am Oak's song "On Trees And Birds And Fire" speak to the idea of nostalgia and memory. The repeated lines of "Trees, oh trees, do you remember me?" and "Birds, oh birds, can you recall my songs?" suggest a longing to go back to a time or place where the singer felt more connected to nature and the world around them. The inclusion of fire in the third verse adds to this sense of longing and connection, as the warmth of the fire is something that is physically felt and remembered.

Overall, the lyrics seem to ask whether the natural world remembers us as much as we remember it. This idea is supported by the repetition of "From before" in each of the first two verses, which emphasizes that the memories being referenced are from a time in the past. The use of the word "recall" in the second verse also emphasizes the idea of remembering and brings a sense of urgency to the question of whether the birds remember the singer's songs.

In the end, the song leaves the question of whether the natural world remembers us unanswered. Instead, it offers a sense of comfort in the idea that the warmth of the fire can still be felt, suggesting that some things can stay with us even as time passes and memories fade.
