In Svalbard, Norway, bearded seals give birth on small, first-year, ic
e flows in the free-floating packice or on similarly sized white, glac
ial-ice areas frozen into gray, land-fast ice. Sites of the latter typ
e usually were located near the edge of the ice. Access to the sea was
always readily available; all birth sites were <1 m from water. Well-
formed, dark, gray, lanugo hair disks, similar to those of hooded seal
s (Cystophora cristata), were found at all parturition sites of bearde
d seals. All young weighing <40 kg had a mixture of 30-mm long, wavy,
gray hairs and 20-mm, straight, coarser hair of a somewhat darker gray
. Older, larger young had increasingly less lanugo and more stiff hair
.
