  1. Marine Birds

  2. Reptiles, Birds, Mammals • Phylum Chordata • Subphylum Vertebrata • 3 Classes: • Class Reptilia • Class Aves (birds) • Class Mammalia

  3. Birds Evolution http://www.zoology.ubc.ca/~bio336/Bio336/Lectures/Lecture5/dinobird.jpg http://www.phyletisches-museum.uni-jena.de/images/archaeopteryx_berlin_1864.jpg

  4. Birds • Advantages over reptiles: • Can fly (almost all), hollow bones • Endotherms, homeotherms (retain generated body heat and regulate it to a constant temp.) • Feathers waterproofed w/ oil • Layer of body fat (penguins) • Eggs with hard shells

  5. Marine Birds • Only 3% of all bird species • Evolved from different groups of land birds • Spend significant part of life at sea • Feed on marine organisms http://farm1.static.flickr.com/78/243136146_c609f7f34d.jpg?v=0 http://www.stanford.edu/~bhackett/los-cabos-2004-06/images/cormorant.jpg http://www.naturespicsonline.com/galleries/Nature12/_mg_2896a_std.jpg?1237927987 http://creagrus.home.montereybay.com/SUSC-wClam5Mr08ML_8093f.jpg
