  1. Clatsop County Mammals:Eight small prey items for larger creatures… Broadway Middle School Life Science 2009-2010

  2. Trowbridge’s ShrewSorex trowbridgii www.ucpress.edu/books/ pages/5776/5776.ch04.html Identification: two-colored tail. http://www.washington.edu/burkemuseum/mammalogy/mamwash/sotr.html Order Insectivora, Family Soricidae For more information about Soricidae: http://animaldiversity.ummz.umich.edu/site/accounts/information/Insectivora.html

  3. Range, Habitat and Diet • Habitat: • Open areas • Woodlands • Forests • Diet: • Insects • Most individuals live no longer than 18 months. http://www.washington.edu/burkemuseum/mammalogy/mamwash/sotr.html

  4. Townsend’s ChipmunkTamias townsendii Identification: Chipmunks have stripes on their face; ground squirrels do not. Order Rodentia, Family Sciuridae For more information about Sciuridae: http://animaldiversity.ummz.umich.edu/site/accounts/information/Sciuridae.html http://www.washington.edu/burkemuseum/mammalogy/mamwash/tato.html

  5. Range, Habitat and Diet, etc. • Habitat: • Coniferous forests • Brush • Diet: • Seeds, flowers & fruits • Habits, breeding: • Hibernates • One litter per year, • 2-6 young http://www.washington.edu/burkemuseum/mammalogy/mamwash/tato.html

  6. Douglas Squirrel,Tamiasciurus douglasii • Identification: • Dark gray on top • Orange underneath • Black stripe from elbow to knee • Pale eye-ring http://www.washington.edu/burkemuseum/mammalogy/mamwash/tado.html

  7. Range, Habitat and Diet, etc. • Habitat: • Coniferous forests • Diet: • Seeds of conifers • (from the cones) • Habits, breeding: • Does not hibernate • 1 to 2 litters per year, 4-6 young http://www.washington.edu/burkemuseum/mammalogy/mamwash/tado.html

  8. Northern Flying Squirrel,Glaucomys sabrinus http://www.washington.edu/burkemuseum/mammalogy/mamwash/glsa.html http://animaldiversity.ummz.umich.edu/site//resources/phil_myers/classic/sabrinus1.jpg/view.html (upper right) Identification: Large eyes, membrane from elbows to knees for gliding http://www.enature.com/fieldguide/showSpecies_LI.asp?imageID=18791

  9. Range, Habitat and Diet, etc. • Habitat: • Coniferous forests • Mixed forests • Diet: • Lichens • Fungus (important: Flying Squirrels disperse fungal spores and bacteria in their scat that help fix nitrogen; clearcutting breaks that cycle and makes it difficult for the forest to regenerate) • Habits, breeding: • Nocturnal • Glides from trees • One litter per year, 2-5 young http://www.washington.edu/burkemuseum/mammalogy/mamwash/glsa.html
