The sticker that somehow wound up on Sunbird's tail-bag looks just like the label on commercial Mulch. It should come as no surprise that the content of Sunbird's tail-bag is nutrient-rich compost, which it scatters everywhere, even indoors.

It carries food bundled up in its tail. Sunbird try to minimize movement to conserve the nutrients they have stored in their bodies for evolution.
