Maps

Raptors sometimes fly long distances.  This is obvious for migratory species - tundra Peregrine Falcons from Canada, Alaska and Greenland reach Patagonian Chile and Argentina on their seasonal movements to wintering areas.  Sedentary species too sometimes exhibit considerable dispersal.  Because of this, and because our knowledge of bird distributions is being updated continually, range maps should be used with caution.  Despite this they are extremely useful because we can learn at a glance whether or not a species has been recorded in a particular area. 

Raptors of South America will have four-color maps showing breeding and over-wintering (non-breeding) ranges, as well as areas where the species is observed only during migration, and where the species is resident year round.  Subspecies’ boundaries will be indicated with trace lines.  Arrows will call attention to individual records away from known distribution, or isolated, small populations.  Areas where the species is expected to occur but has not been recorded will be noted.  For rare species individual records will be plotted discriminating those documented (museum skin, call recording, photograph or video), from undocumented sightings.  Standardized maps (focusing on regions of the continent or the continent as a whole) will include country and provincial or state boundaries.
