The report on the latest population estimate for harp seals off the east coast of North America was released in late March without fanfare and therefore no media attention. This was one of the missing scientific reports mentioned in my State of the Polar Bear Report 2019 released in February (Crockford 2020): results of surveys promised for months or years by early 2020 but not delivered.
Not surprisingly then, we find the report has good news: the population estimate of harp seals in the NW Atlantic has risen to about 7.6 million (range 6.55-8.82) animals (DFO 2020), up from 7.4 million in 2014 (DFO 2014).
Note that the survey was done in March 2017, a low ice year for the Gulf of St. Lawrence (see discussion below) and while this may have resulted in some increased mortality for pups born there, it is also known that many ‘Gulf’ pregnant females will instead have given birth off Newfoundland and Labrador in a whelping region called ‘The Front’. Apparently, these factors were accounted for in the population model.
Harp seal pups born at the Front are an important food for Davis Strait polar bears. This increase in the prey base for Davis Strait polar bears suggests the bear population may have grown substantially since the last survey in 2007 (Peacock et al. 2013; Rode et al. 2012). Davis Strai is the only subpopulation of polar bears officially considered to have ‘likely increased’ at 2018 by Environment Canada. A new Davis Strait population size survey was apparently completed in 2018 but the results are not yet available (Crockford 2020).

Newborn harp seals are food for Davis Strait, East Greenland and Kara Sea polar bears but wildlife photographers see only cute furry babies with big eyes and trusting natures.
See these photos taken some unknown spring (early March) in the Gulf of St. Lawrence, Canada (published 29 December 2015 by Mailonline): the pups are kind of skinny when first born but fatten up quickly on fat-rich milk from their attentive mothers. Ask yourself: does this photographer know that the fattest of these baby seals he oh’s and ah’s over in his commentary are just what polar bears depend on for their existence – and that the bears will eat as many of them as they can catch, peeling them like bananas so that they can eat the skin and fat first?
The title of the piece is: “Eye-eye! Cheeky seal cubs just a few days old wink and pose for the camera as they wait for their mother to feed them:
- The young Harp seal pups had never seen humans before the pictures were taken
- They were photographed in their habitat of Madeleine Island in Quebec, Canada
- Harp seals are solitary animals except during breeding season, when they congregate in their thousands“
“These seal-ebrities from Canada are pictured striking hilarious poses that even Cara Delevingne would be proud of.
The three Harp seal pups – just days old – were passing time while they waited for their mother to return from hunting.
One pup looked straight to the camera with a cheeky wink, while another lay on its back looking longingly at the lens.
The impressive poses were captured by photographer Gunther Riehle, who was lucky enough to get just feet away from the baby seals on Madeleine Island in Quebec.”
