North Atlantic right whales: 23 calves, the best season since 2009

Published · Researched 2026-09-22

What happened (dated facts)

The 2026 North Atlantic right whale calving season produced 23 calves — the highest number of births since 2009 for this Critically Endangered species of fewer than 400 animals. Twenty of the 23 mothers were experienced breeders returning with calves. NOAA Fisheries and the New England Aquarium reported the season as a sign of cautious optimism.

Why it is genuinely positive

For a species with under 400 individuals, a season like this is a demographic lifeline — and 20 of 23 mothers were return breeders, showing the adult females are surviving.
