Mating pair, with a spun white gift ball with a treat inside for the female. I saw about 10 males flying around or hovering while holding this 'gift' balls in chaparral areas in Edgewood Park. Warm sunny with light breezes.

Descrição
Another observation, iNat 148304242, was made 2 hours after this one and a few hundred feet away.
As presently circumscribed, the genus Taricha has 4 species: 3 of those species are endemic to CA (T. rivularis, T. sierrae and T. torosa); while the remaining one (T. granulosa) ranges from Alaska through British Columbia, Washington, and Oregon to California...and east into Idaho & Montana.
The deep "tomato-red" underside & feet here are suggestive of Taricha rivularis. However, the other species can sometimes exhibit similar coloration...as shown in images on the Taricha ID page from the CaliforniaHerps web site. Apparently 3 of the 4 species are present in this local area of the Santa Cruz Mountains (excluding T. sierrae , which is only found in the Sierra Nevada) . The CaliforniaHerps Taricha ID page stresses that T. rivularis is distinguished by its entirely-dark eyes (as opposed to eyes partly-yellow in T. torosa and T. granulosa). Further interesting info and many helpful photos appear on the T. rivularis species page at CaliforniaHerps.
Note that the fairly-wide black band across the vent on the underside (see 5th photo, behind hind legs) indicates a male...and is another diagnostic character confirming the species ID of T. rivularis.
This Santa Cruz Mountains population of T. rivularis was relatively-recently discovered (in 2009) and is only known from a relatively-small area in Santa Clara County...where it's mysteriously disjunct from the main population of T. rivularis in Sonoma, Mendocino, and Humboldt Counties. The story of the discovery...and the many questions it engendered...is briefly touched on in this "Bay Nature" article, and voluminously recounted & explored in the excellent multi-part blog "Mystery of the Red-Bellied Newt", as well as the related-blog "Homegrown Tomatoes". And the population is also the main focus of the paper below:

Of course I had to look for it. Fortunately @sandy_b gave me some hints, one being it was slurping on Eriogonum nudum. Amazing!
