Visitors to our park

We have two Egyptian geese who have started visiting our park each day.  I am not sure where they come from - or go to but it is lovely to see them.  These duck like geese feed on greenery and potter around the park woofling the grass and any other shoots.  They are chased by the dogs who daily exercise in the park so don't think they will stay long.  Yesterday one of them flew up into one of the trees, the other called and called, eventually the tree one flew down, they cuddled up and then they  both flew away.  They do nest in trees so perhaps they are looking for a new home.
