Calf Count Reaches Seven

Check Mark (North Atlantic right whale catalog No. 3705) and calf off Amelia Island, Fla., on Jan. 17 (FWC/NOAA permit 26919)

Add a calf and another first-time mother to the calving season totals.

The 18-year-old female called Check Mark, whale No. 3705 in the North Atlantic right whale catalog, was seen with a calf about 9 nautical miles of Amelia Island on Jan. 17. That bumps the calf count this winter to seven.

The sighting by the Florida Fish and Wildlife Conservation Commission’s aerial survey team came a day after the season’s sixth mom and calf were spotted , also off Amelia Island. But that mom — Grand Teton (catalog No. 1145) — was over 44 years old and the calf was her ninth. For Check Mark, this is her first known calf.

Named after a partially sliced off fluke that now resembles a check mark, this new mom has a well documented lineage. More than 25 members of her family are in the whale catalog curated by New England Aquarium. That includes parents mom Smoke (No. 2605) and dad Velcro (1306), grandparents Sliver (1227) and Phoenix (1705), and great-grandparents King Richard (1147) and Mavynne (1151), plus six siblings, three nieces and nephews, four aunts and uncles, one cousin, and seven great aunts and uncles.

FWC’s Fish and Wildlife Research Institute notes that while many right whales first give birth at ages 8-12 — females become sexually mature at about 10 — the timing for becoming a mother has trended older in recent years. For example, Caterpillar (No. 3503) is another first-time mom this winter, and she’s at least 20 years old.

In addition to the energy demands of pregnancy and nursing, scientists point to stress caused by entanglement in commercial fishing gear and collisions with ships and boats (both Check Mark and Caterpillar bear scars from vessel strikes), along with finding enough food, as reasons why these endangered whales are calving later and less often, according to the Fish and Wildlife Research Institute. NOAA considers three years between calves “normal or healthy.” But females are now averaging a calf every 7-10 years.

Which makes every mom and calf even more special.

WHAT YOU CAN DO

You may have heard, or read, this before, but it bears repeating: When boating off the Southeast Atlantic’s coast from November to April, follow guidelines for Navigating in Right Whale Waters (here’s a flyer that sums it up for recreational boaters):

(If used by media or other outlets, the right whale images in this post must include the following: Taken by Florida FWC under NOAA permit 26919. Also note that it is illegal to approach right whales in U.S. waters without a research permit. Other vessels, aircraft and drones must maintain a distance of at least 500 yards from these endangered whales.)
