Happy Spring! As the main tidepool season starts winding down, the Spring flowers start to bloom. You can also see some very cool photos that Pauline took of two Moray Eels near the tidepool entrance. There is a video as well on the Tidepools Videos page. She also captured a video of an Osprey catching a fish from the tidepools.

Here is a sampling of what our volunteers observed during this month — thank you to everyone who contributed. Remember to send in your photos; we truly appreciate sharing them with everyone.
