I can report, although informally, that I did not hear or see many bluebirds while I visited various nest boxes around Castle Rock for box maintenance & repair this season. In fact, despite visiting 14 different sites between the first week of March and yesterday (always on calm sunny days), I heard/saw bluebirds only twice. That is definitely very low compared to previous years. But I can also report more specifically that we found only 3 complete nests and 5 incomplete nests in our 190 nest boxes last week during the first week of monitoring, compared to 5 complete nests and almost a dozen incomplete nests during the first week of monitoring in 2020. We too have a very detailed monitoring program with extensive data keeping since 2007, so we will have a good opportunity for data comparison at the end of the season. -Barbara Spagnuolo, Castle Rock (Douglas County)

This year we have seen only one or two of either species only once in a while. The last 3 years we saw them almost daily starting in mid-March. This drop seems striking, at least along our road and on the trail we walk regularly. Have others noticed this pattern?
