2020 Gray whale abundance in Laguna San Ignacio and Bahia Magdalena, B.C.S., Mexico

2020
The winter gray whale occupation of Laguna San Ignacio (LSI) and Bah??a Magdalena (BM) in 2020 was characterized by the delayed arrival of the whales to the lagoon; low numbers of calves-of-the-year; an increase in mortality, and an increased percentage of "skinny" single whales. Seven stranded dead whales were discovered in LSI, and four discovered in BM. Decreasing prey resources on the summer feeding grounds are possible contributors to the whales' delayed migration, low calf counts, "poor" body condition, and mortalities.
