Naturalists in the Californias (Baja and the one north of the border) have some rare good news about an imperiled species: the glorious monarch butterfly.

The Butterflies Are Back! is a recent report on NPR that describes a small rebound in the west-coast population of the migratory insect. The enthusiasm of those who monitor the annual migration reminds me of the thrill I had when observing the migration at my former home in Pharr, Texas. There we could observe the migration of the east-coast monarchs without even trying. At times they would simply waft past us in their thousands.
The report concludes with an important word of caution: the modest rebound is a cause for optimism but not for complacency. We are in the midst of a century of human population growth that biologist E.O. Wilson describes as The Bottleneck, which I described in some detail in my 2016 post Good News from Gorongosa.
