Click here to view documents, video, and other contextual information.

You can use the filters on the right to sort events by category, and the drop-down list at the top-right to sort taxonomies.


Click the checkbox at the left of the timeline window to engage the timeline controls. You can then control the timeline using the stop, start, step forward, and step backward buttons.

Use the rewind button to return to the beginning of the timeline.

You can keep track of the approximate population of eastern gray whales using the dynamic population count at the top right of the timeline window. You'll also notice a colour-coded graph in the background of the timeline - this corresponds with the population estimate displayed at the top of timeline window, and also with the colour of the animated migration path each year.

You can return to these tips at any time by clicking the An icon of a lowercase I icon at the top right of the page.
