This isn't a simple question that can be easily answered. When you say "each time you show up", would you say you are alluding at a slant to yourself or individuals by and large? It likewise relies upon where you are-such in a city with few trees, a garden with trees and shrubs, or out in "nature". There are by and large winged creatures all over, and their sudden appearance may essentially be on the grounds that you, a vast moving creature, panicked them from wherever they were roosting or scrounging and turned out to be all of a sudden obvious to you since they moved. In the event that they hadn't moved, you probably won't have seen them.
