Improvements in or relating to a colonial-seabird nesting and feeding structure

A method of siting and assembling a colonial-seabird nesting structure 10 with a plurality of seabird support elements by determine a geographic location and an orientation of the support elements. The geographic siting location may be determined based on colonial seabird biology data, position of a body of water or building relative to the nesting structure, terrain data, topography, time series data about wind, solar irradiation, sun path, sun azimuth, sun elevation, shade or proximity to existing colonial seabird populations, predators or habitats suitable for a predator. The orientation of the support elements may be determined based on temperature, wind, rain or sun exposure, visibility of a body of water and/or a protective side wall of the support elements. The seabird support elements may face in the same or different directions. The structure may be altered by moving it, or adding or removing a protective side wall, viewing element, window, capture device or feeding aperture. The structure is also claimed.
