Yes, these birds are creepy! They scavenge and are the grim reaper of nature! They are large and in charge. Just their look makes you shutter. I came across vultures eating on a country road a couple years ago and they were massive and did not budge. I had to wait for them. These particular ones I came across in of course a ghostly tree. Ready for their take in some Alfred Hitchcock movie. I was on a backroad in Indiana County, PA.
While they may give some of us spine tingling chills, they are necessary. Vultures are the maid service. Their sense of smell picks up fresh kill. They prefer a new kill verses very rotted. I have read their scavanging actually helps prevent the spread of disease to other animals.
