EARLY: Sea Animals: Herring spawn occurs, the crucial beginning of the year for much of our marine ecosystem. Many rockfish spawn.
Land Animals: Tree frogs sing in the ponds.
Plants: Early wildflowers grow on south exposed areas; wild plum and cherry bloom; early stinging nettles are ready to be picked.
Birds: Eagles lay their eggs shortly after the herring spawn; pigeon guillemots arrive at their nest sites; first warblers arrive; flocks of brant and Canada geese and ducks are seen and heard heading north; early hummingbirds seek out pink currant and salmonberry flowers.

MID: Sea Animals: Sea lions leave for the summer; newly hatched herring can be seen at Ford Cove and in bays; short-lived jellyfish and sea cucumbers appear; river otters mate.
Land Animals: Mason bees emerge from cocoons and begin collecting pollen.
Plants: Wildflowers in full splendour: trillium, chocolate lily, bleeding hearts, Easter lily, Indian paintbrush, spring gold, gold stars, camas, blue-eyed Mary, calypso orchid, orange honeysuckle and sea blush; alders and maples turn green again; pollen is shed from the maple, alder and other trees; salmonberry and red flowering currant bloom; thimbleberry, Saskatoon berry and mahonia in flower.
Birds: Purple martins return from South America; swallows return; harlequin ducks, mergansers and common loons leave for their interior nesting sites; male rufous hummingbirds do spectacular dives to impress the females (who are busy collecting cattail fluff and spiders’ web for nests); scoters, long-tailed ducks and scaups gather in huge flocks prior to migration; other seabirds and shorebirds moult to breeding plumage and assemble in larger flocks than usual; mergansers do their courtship dances; unusual migrating birds may make a rest stop in the area.

LATE: Sea Animals: Harbour seals move back onto Norris Rocks and Flora Islet after being pushed away by the sea lions; blueback coho feed on herring and grow a pound a month; eelgrass meadows become a nursery for baby fish and invertebrates.
Land Animals: The huge silk moth takes flight.
Plants: Wildflowers in full bloom; oyster mushrooms appear with the first warmer rains.
Birds: Eagles feed their voracious young; most seabirds and shorebirds leave for their nesting grounds; some non-breeding harlequin ducks stay for the summer; oystercatchers, Canada geese and pigeon guillemots are nesting; first Swainson’s thrushes are singing; juvenile purple martins arrive.
