The window that looks out into our backyard is our cat's favorite hangout spot...because of all the birds. Jason recently picked up an Oklahoma bird field guide which stays on the dining room table near the window so we can look up all the birds that frequent the bird feeder that we liberated from the curb in front of someone's house last fall.
At one point I identified eight different bird species hanging out all at the same time: European Starlings, Common Grackles, Mourning Doves, Dark-Eyed Junkos, a Downy Woodpecker and a Red-Bellied Woodpecker, a House Finch, House Sparrows and Cardinals. There must have been over forty birds out there!
We just bought some suet for the woodpeckers and added a new type of seed mixture to keep everyone happy (including the cat).
