MARTIN THIEL ET AL.Table 2 Breeding abundance and conservation status of seabirds (number of pairs) and mammals(individuals) on the coast of northern-central Chile. The geographic divisions correspond approximatelyto the limit of political division of Chile. Data for cetaceans (ψ) correspond to systematiccounts during oceanographic trips conducted every January (1999, 2002, 2003 and 2004) surveyingan area of ~420 km 2 . The other data for cetaceans are mainly from sightings made from the land.Species 18–21°59′S 22–26°59′S 27–29°59′S 30–32°59′S 33–34°S Total CS*SeabirdsOrder SphenisciformesHumboldt penguin Spheniscus8120 810 8930 Vhumboldti φMagellanic penguin Spheniscus5 5 NTmagellanicusOrder ProcellariiformesPeruvian diving-petrel Pelecanoides4170 4170 Egarnotii φWedge rumped storm petrel9 9 LCOceanodroma tethysOrder PelecaniformesPeruvian booby Sula variegata φ 15,560 15,560 LCPeruvian pelican Pelecanus400 1000 1400 LCthagus φNeotropic cormorant Hypoleucos200 50 55 305 —brasiliensisGuanay cormorant Leucocarbo12 150 162 NTbougainvillii φRed legged cormorant Stictocarbo 122 85 60 23 150 440 NTgaimardi φOrder CharadriiformesBand tailed gull Larus belcheri φ 1 1 LCGrey gull Larus modestus φ 10,000 10,000 LCKelp gull Larus dominicanus 2700 100 450 3250 LCInca tern Larosterna inca φ 10 10 NTPeruvian tern Sterna lorata φ 2499 EMarine mammalsOrder CarnivoraFamily OtariidaeSouth american fur sealArctocephalus australisSouth american sea lion OtariaflavescensFamily MustelidaeMarine otter Lontra felina(ind./km of coast)655 1205 1860 LR13,797 6132 129 1598 21,656 LR1.5 1.0–2.5 EOrder Cetacea (numbers come from sightings)Family BalaenidaeSouthern right whale Eubalaenaaustralis21 21 LR222
