chicks and ducks and geese better scurry

Every day while sitting at work,  I look out the window and see geese in the park, usually 4 or 5.  They are always accompanied by about 15 ducks.  There are times when I see people with sacks full of bread feeding these birds.  There have also been times when I see people being chased by these animals.  Well, today I look out and see the geese on the sidewalk, all 5 in a row watching the cars pass by.  Their heads in unison as one car passes to the left, then to the right.  10 minutes pass by, they seem to tire of this activity, waddle back to their posse of ducks and head for the elderly couple with bread in hand.
