Question
In the course of your observations, did you notice any signs of the presence of living things, though the living things themselves were not seen? For example, did you notice any partly eaten fruits or shells, fallen feathers, animal tracks, dung, droppings, nests, cocoons, eggs, honeycombs, etc.?
Solution
Different types of living things are seen in different places. Some signs of their presence are seen sometimes, even if these living things are not seen themselves. For example, partly eaten fruits. shells, fallen feathers, animal tracks, dung, droppings, nests, cocoons, eggs, honeycombs, etc. are noticed during observations. Partly eaten fruits can confirm that there were squirrels, monkeys, or some fruit-eating birds before we arrived. From the fallen feathers, one could guess about the types of birds that visited the place. We can also guess from the animal tracks, pugmarks, dung, or droppings.
