One Second in Nature is a mirrored image again in time to a second of discovery as I explored the pure settings round me. By means of the sharing of this second, is my hope that readers will change into motivated to be taught extra about our surroundings and its inhabitants, and change into passionate advocates for conservation.

THE WESTERN GREBE MOMENT – Previously conspecific with the Clark’s Grebe, in 1985 the AOS break up them from completely different morhped subspecies to full species. One in all my fellow photographers has some award-winning photos of grownup Western Grebes feeding their younger and that type of a photo-story was excessive on my checklist. A go to to household in SoCal in August (2025) gave me a chance to go to the San Joaquin Wetlands in Orange County. To my nice awe, that is what I used to be dreaming of as each Western and Clark’s Grebes have been within the technique of elevating younger. The angles I had weren’t serving to me as a result of cattails alongside the shore. I lastly discovered a really small opening and to my luck a household floated proper as much as the place I used to be positioned.
As I used to be at targeted on simply composing as many photographs as I may, I didn’t notice immediately that this was a combined species household. Once I double-checked a few my photographs on the viewscreen I did a double-take. One was clearly a Western and the opposite grownup was a Clark’s. Clearly the infants couldn’t care much less, so long as they have been getting some tasty fish for breakfast.
WHAT’S IN A NAME – Aechmophorus occidentalis; Greek aikhmophoros = spearman; Latin occidentalis = western
PHYSICAL DESCRIPTION – The Western Grebe is a slender, long-necked waterbird with a pointy black-and-white distinction: its black cap extends beneath the attention, giving it a hooded look, whereas the remainder of the face and neck are brilliant white. It has a straight, yellowish-green invoice and crimson eyes, and its physique is smooth and dark-backed with pale underparts.
In distinction, Clark’s Grebe has a whiter face with the black cap stopping above the attention, a brighter orange-yellow invoice, and barely paler total plumage. These delicate variations, particularly in facial sample and invoice shade, are key to distinguishing the 2 species after they happen collectively on California lakes.
STATUS AND DISTRIBUTION IN CALIFORNIA – The Western Grebe (Aechmophorus occidentalis) is broadly distributed throughout California, occurring year-round in giant freshwater lakes, reservoirs, and coastal estuaries, with notable breeding concentrations within the Central Valley and japanese Sierra Nevada. It’s usually frequent, forming conspicuous flocks and fascinating in elaborate courtship shows, together with synchronized “speeding” throughout the water’s floor. The species is listed as Least Concern by the IUCN, although native populations could also be affected by water degree fluctuations, nest disturbance, and contaminants. Pure historical past observations spotlight its fish-based weight loss program, floating nest platforms anchored in emergent vegetation, and robust website constancy to conventional breeding colonies.
