The cypress trees in the wetland near the proposed DePave Park at Alameda Point have served as a safe and secure nesting site for Great Blue Herons for many years. This year is no exception, despite the trees having died and barely standing. On May 7, Audubon Society bird observer Dawn Lemoine counted 13 juveniles in the nests.
The brightly colored male and its grayer colored mate were spotted briefly landing on top of an old light pole, as if to show off their insect catch. More likely it was a precautionary stop to ensure that no predators were lurking nearby before springing into air and entering the nest cavity in the pole just below the top.
This was the only clue in early May 2020 that a pair of Western Bluebirds had a nest at the old campground at Alameda Point. The chicks were silent and unseen for weeks until they began peering out of the hole a few days before flying away.
A Snowy Egret caught two Bay pipefish in quick succession along the shoreline next to the Hornet Soccer Field on Sunday, November 24. This sighting of the Snowy Egret catching a pipefish is evidence that eelgrass, a special status marine vegetation, is present in the harbor east of the ferry maintenance facility. Pipefish “do not wander far from the eelgrass bed where they were born,” according to Bay Nature magazine. Eelgrass is pipefish habitat, in part, because pipefish are able to avoid predators as their slender bodies blend in with the narrow blades of eelgrass.

This Red-breasted Nuthatch was part of a small flock busily feeding in an evergreen tree in the old campground next to the Bay Trail on October 15th. Notice the bird’s legs in the first two photos. It looks like it is standing on long stick-like legs, which is an illusion.
Great Egrets are commonly seen wading along a shoreline, in marshes and wetlands waiting for fish to come near before catching them with a quick thrust of its bill.
Great Egrets primarily eat small fish. However, their diet can also include reptiles such as lizards, amphibians, birds, small mammals, shrimp, worms, dragonflies, beetles, water bugs, and grasshoppers.
This particular Great Egret decided to stroll into the old campground at Alameda Point in search of food. It walked slowly up to a Rosemary bush and stood there for about five minutes, occasionally making slight head movements, before plunging its head into the bush to catch a lizard.
After holding the lizard in its bill for a few minutes, it gulped down the lizard and proceeded very slowly to another bush.
Ospreys returned again this year to nest at Alameda Point’s Seaplane Lagoon. But midway through the rearing process, the female became the sole provider and protector of her three chicks, after the male became entangled in fishing line. Such osprey single parenting is unheard of.
