Naturalist notes
By late May the first broods of western fence lizards are emerging on south-facing slopes around the Palos Verdes Peninsula, right as the coastal morning clouds begin their seasonal retreat.
Look low in the western sky just after sunset during early June: Mars and Venus can appear within a few degrees of each other, with the Beehive Cluster (M44) passing through the same field of view on clear evenings.
