A Day in Bremer Canyon
Today’s tour promised an array of cetacean species, heightening anticipation for our encounter with the apex predators of the Bremer Canyon.
As we arrived at the hotspot, disappointment initially loomed, prompting a southwest journey amidst the high swells in search of our elusive targets.
Spotting Pilot Whales and Dolphins
After an extensive search, excitement ensued as blows were sighted off the port side, signaling the presence of pilot whales.
Dolphins gracefully danced among them, setting the stage for an enthralling morning.
Suddenly, a larger baleen whale, a Fin whale, emerged, leaving spectators in awe with its sheer size and rarity.
Baleen Whale Feeding Behaviour
The Fin whale’s appearance was a testament to the abundance of prey in the canyon.
Baleen whales, such as the Fin whale, employ a unique feeding strategy, utilising their baleen plates to filter small prey from the water.
In the Bremer Canyon, their diet comprises small schooling fish, squid, and crustaceans, creating a thriving ecosystem.
Collaborative Feeding Dynamics
As the Fin whale departed, the pilot whales and dolphins returned, joined by flesh-footed shearwaters engaged in collaborative feeding.
Tail slapping and synchronized movements underscored the harmonious interaction between species.
This illustrates the interconnectedness of the marine ecosystem.
Family Dynamics of Pilot Whales
The sight of over 50 pilot whales, including calves and a fresh newborn, provided insight into their social structure and reproductive habits.
Matings and calvings primarily occur during the summer, fostering strong mother-calf bonds within the pod.
Remarkably, post reproductive females play vital roles, continuing to nurse and care for young within the community.
Encounter with Solo Orca and Moon’s Pod
As afternoon descended, our focus shifted to locating the apex predators.
A lone male orca initially teased us with his solitary antics, before the arrival of Moon’s pod.
With breath-holding dives and playful surges, the orcas captivated us, providing an unforgettable interaction.
Conclusion: A Day of Variety
Wrapping up our expedition, smiles abounded as we reflected on the diverse encounters throughout the day.
From baleen whales to playful dolphins and majestic orcas, our journey exemplified the rich biodiversity and dynamic behaviour within the Bremer Canyon.
