One of the many things we enjoy is feeding the birds. We get several different varieties coming to our feeders throughout the year. Some come every day and others only at certain times of the year. A few are rarely seen and it's a real treat when they do show up.
This morning one of our first visitors was a Magpie (Black-billed Magpie - Pica hudsonia), who flew off before I could snap a picture! The Mourning Doves (Zenaida macroura), don't fly off they move away till they feel the coast is clear and go right back to feeding. I could hear a Crow (American Crow - Corvus brachyrhynchos), but it was not to be seen. One of our frequent visitors is a covey of California Quail (Callipepla californica) which were introduced to our state in the early 1900's.
Oregon Department of Fish and Wildlife has a great page you can visit that has great information about our native and nonnative species which inclues a link to allow you to hear the bird calls:
