This year we are excited that we have a pair of Western Bluebirds nesting in a nest box on our property southwest of Eugene. This has not always been the case, so we feel very fortunate to have them successfully raising six chicks this year. As I write this in mid-June, these chicks are within a day or two of flying. The pair of adults may even nest again this year if all goes well!
It is quite a treat to see them on a daily basis. They hunt insects in the vegetable garden, come to the water source in the front yard, and make food deliveries to the nest box throughout the day. They vigorously defend their box from any other birds that get too close. One morning the male bluebird chased off a Western Wood-Pewee looking for a perch and forced it to move on to a nearby tree.
Western Bluebirds have population pressures due to habitat loss and competition from other bird species, mainly European Starlings and House Sparrows. These two non-native species nest earlier and take nest cavities that might otherwise be used by bluebirds.
