Article Summary:

Photographer Tony Wu spends more than a month each year photographing humpback whales in the calving grounds near Vava’u, Tonga. For the past two years, he and his network of local friends have been cataloging humpback calves in August and September. This year, they have photographic IDs of 26 calves (compared with 14 in 2008), as well as 25 additional sightings where they were unable to identify the calf in question.

Tony’s results are available as a PDF download. If you’d like to help in this year’s calf survey, please contact Tony directly.
