Black algae chemical attack

I used blades of grass in the foreground to add interest, and play on the color of the algae.

Canada geese visit this fishing platform to dine on the algae that forms in what's become a tidal zone.

No graphics please.

The substance on these branches is 'Trentepohlia', a genus of filamentous green chlorophyte algae which lives on tree trunks and wet logs. The strong brownish-orange color of the filaments, which mask the green of the chlorophyll, is caused by the presence of large quantities of carotenoid pigments. I noticed this unusual algae growing on some Monterey Cypress trees at the top of a high bluff overlooking Woodcrest Beach on the Pacific Coast in Half Moon Bay California.

Trying to identify this algae.

Clearlake, Ca.

Ducks normally keep this small mountain lake clear, but an unusual heavy algae growth has greened it up for an extra splash of color.

I watched this American Goldfinch (Spinus tristis) pluck algae from a small pond and then eat it. At first I thought it was eating the Duckweed but after watching closely with binoculars I saw that it was after the green algae. Checking the literature I found out that this has been observed a number of times but usually when the water level had dropped leaving the algae high and dry for the birds. This Goldfinch was not waiting and was plucking the algae from under the surface of the water. Small pond at Centennial Park, Howard County, Maryland.

They're not very good pictures, but I loved the patterns that this created with lots of layers of algae in perfectly clear water
