The Fabled “Green Flash” at sunset or sunrise can sometimes be seen on crystal-clear days in January. At the instant the sun’s upper rim is last visible at sunset, and also at the instant when it is first seen at sunrise, a flash of emerald-green color may be observed, especially on a flat horizon. Physicists explain this peculiar phenomenon as due to color-dispersion (as in a prism) and scattering of sunlight through the Earth’s atmosphere. Binoculars (or a small telescope) are helpful in spotting it. For green-flash hunting at sunset, any site with a view of the ocean horizon suffices. For the sunrise green flash, any spot overlooking the low desert (Sunrise Highway in the Laguna Mountains, for example) is good.

Hummingbirds Are Zipping Around San Diego County’s backyard gardens, scrub-covered coastal hillsides, and the warming Anza-Borrego Desert. Seasonal hummingbirds are making their way back to Southern California in preparation for breeding season in early Spring. Resident hummingbirds like the Anna’s often dive bomb invaders to defend their turf. Male hummingbirds tend to patrol larger areas (up to a 1/2 acre) to defend mating territory. Female hummingbirds dive-bomb too, but tend to be localized around smaller nesting areas. Dive-bombing tends to be accompanied by a sound which the birds make by fluttering their tailfeathers while diving. Males will also dive as a mating “dance” to impress a female.

Ornamental Pear Trees, one of the earliest-to-bloom trees in San Diego, are about to bear their white flowers. The thousands of blossoms appear in sheets and clusters, looking rather like snow when viewed from a distance. Nice specimens can be seen along Lake Murray Boulevard, along Clairemont Mesa Boulevard between Highway 163 and Interstate 15, and in parts of downtown San Diego.
