We left Bahia de Chamela on January 14
th for the short four-hour
trip to Bahia Tenacatita, arriving around 2:30pm and anchored in the bay.
As dusk approached, we heard a whooshing
sound moving through the water.
I went
out on the bow, and to my surprise saw a mother humpback whale and her calf
right next to our boat!
Humpbacks
migrate to tropical or subtropical waters to breed and give birth in the winter
and early spring.
The calf is born tail
first near the surface in these warm shallow waters.
The newborn instinctively swims to the
surface within 10 seconds for its first breath helped by its mother using her
flippers.
Within 30 minutes of its birth,
the baby whale can swim.
The calf nurses
for approximately six months, then a mix of nursing and independent feeding for
about six months more.
We watched
quietly as mother and calf moved slowly near our boat, perhaps in the nursing
and feeding phase.
We noted that the
mother whale would spout or breathe at the surface about 1-2 times per minute
in this restful state, spouting a double stream of spray from her two blow
holes.
Like all baleen whales, humpbacks
are seasonal feeders that filter feed on krill, plankton, and small fish.
During the winter months, adult humpbacks
fast, living off their own fat.
Humpback
whales have a gentle and docile nature except during the winter breeding season
when males have brief bouts of fighting.
The males also sing haunting songs and put on quite a show, thought to
attract the females by slapping their flippers and lob-tailing.
Most spectacular is the high breach, finished
with a tremendous splash.
It’s no wonder
that humpbacks are popular among whale watchers and can easily be identified by
the stocky body, humped back, and by the knobs or tubercles on its head and
lower jaw.
Being so close to our boat,
we could clearly make out the knobs on both mother and calf.
After their inquisitive inspection of our
boat, they eventually dove under and we could see the arched or humped back,
from which their name is derived.
