In this lesson: Interpret a revised count without inventing a new event.

Name: __________________________ Date: __________________

Read the story

September photographs from Canada have revealed an uncounted North Atlantic right whale calf with its mother, Silt.

The New England Aquarium reported the identification this week, following image and data analysis. The calf had escaped winter surveys.

Its inclusion brings the known seasonal count to 24. This is a revision to observed births, rather than evidence of a birth this week.
