the windswept shores of
patagonia in argentina
:42:12
once a year
:42:13
right whales migrate
to breed in the warm
:42:15
shallow waters
:42:25
here they are greeted
by dusky dolphins
:42:28
unlike their big
lumbering cousins
:42:31
duskys are small
fast, and agile
:42:38
in the summer months
:42:40
they leave the safety of coastal
waters to hunt miles offshore
:43:00
in deep waters, locating
:43:02
pursuing and catching prey
is exceptionally difficult
:43:06
but duskys have developed
some extraordinary tactics
:43:10
in the morning, small
search parties set out
:43:13
probing with their sonar
:43:20
there may be twenty to thirty
groups patrolling these waters
:43:23
each pod separated
by a mile or two
:43:28
the leaps give them a vantage
point for sighting prey
:43:38
seabirds have gathered up ahead
a sign they've found something
:43:48
this time of year southern
anchovies are here in vast numbers
:43:53
for the penguins
it's a feast
