Key to maps

reddot.png(red dots) core records, known to represent existing locations of focal taxa; in the case of intra-continental migrants, only records approximating the taxon’s breeding distribution are used.

orangedot(orange dots) non-core records, representing vagrant occurrences of the focal taxon obviously outside its usual range, or historical observations of a taxon known to be extinct at that location.

greydot(grey dots) records of other subspecies of the same species as the focal taxon; or in the case of intra-continental migrants, non-breeding records of the focal taxon not included as core records.

blueploy(blue polygons) minimum convex polygons underlying the locational records on the maps that depict each existing taxon’s Extent of Occurrence (EOO).

yellowpoly

(yellow polygons) areas formerly occupied by Extinct taxa.

 

redarrow(red arrows) the location of taxa with very small distributionsand known seabird breeding locations.

Maps were made using the Geoscience Australia Lambert Conformal Conic (GALCC) projection.
