Metro's primary defense against bird droppings is the friendly Border Collie you've seen around the grounds, Kendra. In the picture above, Kendra is hot on the trail of a goose. I asked Metro Superintendent Gary Ingram about birds at Metro, and here's what he has to say:
"Before we had Kendra during grow-in almost half of our labor was used to clean up the mess so we could mow. This time of year is when we have the highest population of both geese and gulls. Most of the droppings are from 8:00pm to 4:00 am on weekdays and weekend afternoons when Kendra is at home."
