To return faster to Siesta Gate, I get on the paved road at the EBMUD water tank.  Loud buzzing of bees can be heard from the big Rosemary bush at the gate. Native to the

It’s not my habit to visit the Skyline Gardens in the afternoon, but I am glad for a pause in the rains – time for a short walk in the afternoon sun.   The long,

How did I manage to miss this Woodrat nest next to the trail after having walked the Skyline Trail regularly for more than a year?  The large, cone-shaped nest has been built at the base

A week has elapsed since our weird bout of cold and snowy weather.  I am elated to enjoy some sunshine at last as I walk the Skyline Trail from the Steam Train entrance.   The

An extensive Wild Cucumber vine is trailing on the grassy slope along Sanborn Drive in Joaquin Miller Park, Oakland.   I immediately notice how much larger and whiter these Marah flowers are compared to the

Someone has been weeding the edges of the paved road to the Water Tower, mindlessly tossing some clumps of grass onto a blooming Hillside Gooseberry, Ribes californicum.  I relieve the branches of their unwanted weights

I stop briefly to check on the Lupin Aphids, Macrosiphum albifrons on the Silverleaf Lupine, Lupinus albifrons.  Yep, they are still there, on the same plant at Diablo Bend.  The aphid’s wax-coated bodies are so

I walk the Bypass Trail to the Swale this sunny, calm afternoon.   Some of the Silverleaf Lupine, Lupinus albifrons along the trail are already blooming. This is a relatively fresh inflorescence.  Why are the
