Harlan’s Hawk spotted at Elkhorn Slough Reserve

Recently what was thought to be a dark red-tailed hawk was spotted at the Reserve by Jane Rudebusch. Upon further observation, from Jane and other staff, they realized it was probably something else.  Local birding experts came out and finally concluded it was a Harlan’s Hawk.  There has been a lot of debate around calling Harlan’s a sub species of red-tailed hawks or it’s own species.  All of that aside, this bird is not normally seen here at the Slough as it is known to nest in remote areas of Alaska and Western Canada.

Mantis Shrimp

pseudosquillopsis_marmorata

Rikke Jeppesen, Estuarine Ecologist here at the Elkhorn Slough Reserve spotted this huge mantis shrimp while out with the Estuary Explorers.

According to Rikke: It was a gigantic mantis shrimp. It is rare in Southern California, so it may have come up here with the warm waters of El Nino. The species is Pseudosquillopsis marmorata, and according to a book about shrimp and crabs: “It emerges at night to prey on bivalves and other organisms that are smashed by blows from the claws.”

Fat Innkeeper Worms on local beaches

IMG_9813 image2

Fat Inkeeper Worms usually live in burrows in the mud in Elkhorn Slough but they were recently spotted on local beaches.

Our researchers confirmed that this seems to happen every few years, always after really strong king
tides.  “They show up on area beaches.  Our best guess is that there are erosional events that collapse innkeeper burrows and sweep them out to sea.”

For more about these events check out this article from the Sanctuary:
