I hesitate to comment on ducks and robins after reading the comment thread, but when I think about ducks and robins I picture the duck swimming on the duck pond and the robin sitting on a branch of a tree overhanging the duck pond. Prod me to to think about disease transmission and I picture the robin shitting in the water in which the duck is diving for weeds to eat. Guess which way I imagine disease transmission going :-)
