Augury of Spring

Three reasons to slow down on Page Mill Road - sharp curves, bicyclists on the road, and wildflowers.
There is a curve on Page Mill Road that is covered with blossoms of Warrior's plume (aka Indian warrior, Pedicularis densiflora) for a few short weeks every spring. It is blooming right now, a bold announcement that the spring wildflower season has started.

Bareheaded Bucks and a Springtime Quiz

Seven bucks in formal antler attire, Dipper Ranch sunset, Christmas 2011

It's the bareheaded season for bucks - by March they should have dropped their antlers. So far this winter, I haven't seen any brown and therefore recently-shed antlers on the ground. On the other hand, all the deer I see right now are antler-less. I play this game in late winter and spring - I try to figure out which are the does and which are the bucks by their body shapes and behavior. If I see a group of deer that are of mixed sizes, I assume it is the matriarch doe with her last two generations of daughters.  If I see a large single deer, I assume it is a lone buck. But I'm not sure, so the guessing game is actually quite fun for the next month or so.

The Columbian black-tailed buck grows and sheds its antlers every year. The antler calendar goes something like this:

Slender hair grass (Deschampsia elongata) is a native California grass. It showed up in the yard after I trimmed back the ancient rose bushes to paint the garage.

Let the Spring Begin

Western leatherwood (Dirca occidentalis), a rare native California shrub, has distinct sprays of bright yellow flowers in the late winter.  Notice the sharp point behind the flower.  This feature often remains behind the flat tip of the branch after the flower falls and is one way to distinguish this plant from the similar osoberry (Oemleria cerasiformis).
Spring has begun almost without a winter.  The local chapter of the California Native Plant Society (CNPS) has several hikes coming up that will feature the earliest of the spring wildflowers.  If we don't get more rain this winter, we may have a short wildflower season, so get an early start and shake that rain stick.  Select "Read more" below for info and links on these hikes.

Coyote Storytelling Event


I've been invited to lead a storytelling evening:

The Coyote Brush Highway
South Skyline Association General Meeting 
Friday, January 27, 2012, 7:00 pm
Saratoga Summit Fire Station

"Mountain resident and biologist, Cindy Roessler, will tell a story and share photos about her recent encounters with a family of coyotes on the Dipper Ranch in the Santa Cruz Mountains.  Coyote (aka the Trickster, the Western Songdog and many other names) inspires stories of wonder, frustration and imagination.  Bring your coyote stories and let's share an evening of real tails and tall tales."

Newt Tracks

Tracks at edge of Newt Pond, San Mateo Co, California, 12/29/2011
Total width 3.8 cm, width of central drag mark 3 mm
footprints 1 cm wide x 1.5 cm long
Probably a track of the coast range newt
This is the track of a tail-dragging animal leaving the Newt Pond. Snakes don't make footprints, our local lizards usually don't enter water, and anyway, it's too cold this time of year for reptiles. Since I know that coast range newts breed at this pond every winter, this is probably a newt track, but why was it leaving its breeding pond in December?

When it comes to interpreting animal sign, observe the where, when and size of the marks, and look around for other clues. By absorbing the nature of the site in addition to observing the actual marks, you can make a good guess at the behavior of the animal.

Tooth, Nail, Beak or Bone?


Katie at Nature ID and I are having a conversation about animal sign on vegetation.  I'm posting these photos for her  and will followup later with details.  I enjoy sharing info online with other nature bloggers - it's a great way to complement our learning.  More photos at "Read More"
