2 years in a row,i had a mama and papa duck in my pool (post winter, before adding chlorine..they seem smart that way) it was kind of tranquil to see these ducks swimming in my pool eating bugs...then they would climb out and sit on the concrete deck and suntan until there next swim..the first year it was just a mama mallard..next year, so she brought a friend..kind of missed seeing them this year. we are right in the middle of our city so it was unusual. that being said, we have a park behind us and one of canada's largest manmade parks 2 blocks over and we see tons of deer in the wintertime when they are foraging for food..5 to a dozen at a time wandering between houses right in the middle of the city!
