The Manchester Bird Sanctuary is an urban green space located in Saint John, New Brunswick, Canada. The Atlantic Coastal Action Program (ACAP Saint John) identified and delineated habitat types suitable for use by wildlife, particularly birds. The sanctuary supported 48 species of birds, including upright-perching water birds, owls, hawk-like birds, pigeon-like birds, swallow-like birds, tree-clinging birds, and perching birds. It was found that the sanctuary was comprised of six habitat types; spruce stand, mixed woods stand, balsam fir stand, fern-sphagnum area, grass field, and an escapee plant species area. It is recommended that there be no development or ‘enhancements’ to the natural state of the area.
