This tree is right near Fairfield Thrifty's / Ross Bay cemetery (on Stannard Ave). It has many giant twiggy/leafy spheres growing in it just like mistletoe. What is this plant/ parasite? A few of the trees on the street have it, but this one the most. I attached a jpg file.
Welcome to the forums Jen Wor. In Britain these are very common in birch trees. Here they are called Witch's broom. Quote wiki....."A witch's broom or witches' broom is a disease or deformity in a woody plant, typically a tree, where the natural structure of the plant is changed. A dense mass of shoots grows from a single point, with the resulting structure resembling a broom or a bird's nest." Witch's broom - Wikipedia Witch's broom tree - Google Search
