Exploring Nature in the San Francisco Bay Area

Least Tern Return

Every spring California least terns return to the Bay Area to breed. These endangered birds, and other terns, have a remarkable hunting style: Drop quickly, and crash head-first into the water. Don't try that at home!

Time for Dungeness Crab

Fall is harvest time for crab fishermen, who place "crab pots" offshore to catch Dungeness crabs. The crabs, the largest species on the West Coast, have a complex lifecycle that takes them from the open ocean to the Bay and back again.

Return of the Coho

Every winter, coho salmon return to coastal streams, though only 1 percent of the half million fish that once filled local streams. But you can still see them, and even help them survive.

Bats Threatened by Wind Power

Studies elsewhere in the country suggest that bats may be suffering even more than birds as more and more windmills get built. And there are no easy answers: New, larger windmills considered safer for birds might be more dangerous to bats.

Termite Emergence

Watch for hungry dragonflies and jays darting about: That can be a sign that the termites are emerging! Termites live mostly underground (or in our walls!) but as winter approaches, they grow wings and take to the air in droves to form new colonies.
