Picking up on what Don wrote, there has been a noticeable trend over
the past several years for the starlings around Prince George here to
nest in the cavity formed where streetlight supports bolt onto telephone
poles, also a favorite of W. Kingbirds in the dry interior of BC and
WA. In fact, in the more urban areas it seems that they now prefer this
rather than a tree cavity. This appears to have taken some of the
pressure off other species which would historically compete for
cavities.

Has anyone else noticed this or is it a local phenomenon?
