Exciting matches in South Pacific catalog

We have been busy in the research department adding humpback whales from the 2016 Hervey Bay field season into our South Pacific humpback whale catalog. Along with adding some new animals, we have already made two matches, which is quite a feat considering that each new photo has to be checked against over 6000 others.

The two matched whales were each sighted with a calf during this field season, meaning we can confidently know that they are females. Both females have a long sighting history going back to 1993. Although we don’t know their exact ages, this sighting span means that both animals are at least 23 years old. As we continue to process the 2016 field data, we’re looking forward to making additional matches like these two in order to help us learn more about the South Pacific humpback whales.

Watching Whales from Land

Did you know that Pacific Whale Foundation studies Maui’s humpback whales from land? Using a piece of equipment called a theodolite, we observe the whales’ behavior and recreate their path of travel. You may have seen a theodolite being used on the side of the road—it sits on a tripod and is commonly used for roadwork and construction projects. It has a powerful telescope that allows our researchers to view whales up to three miles away from shore. Using this telescope, we can determine the overall behavior of the pod, how many animals are in the group, and whether there are any calves present. Once the whales come to the surface, the researcher finds them in the telescope, and the theodolite measures angles between the researcher and the whales. These measurements provide a track of the whales’ location without using more invasive methods such as placing tags on the animals.

Expedition Patagonia

My recent travels took me to Patagonia, Chile to Chiloé, the largest island in the Chiloé Archipelago. My goal is to produce a documentary about an aspiring young girl interested in discovering the largest mammal on Earth, the blue whale. Currently I am editing all the footage taken during my trip. I hope to convey the importance of girls in science and women in conservation leadership roles, specifically to protect whales and their ocean homes.

We departed Maui late at night and after 3 long flights we arrived at Santiago, the capital of Chile. A relatively short 1.5 hour connecting flight to the province of Puerto Mont, followed by a 60 km car ride to Pargua, followed by a 30 minute ferry crossing of the Chacao Channel to Chiloé. We finally arrived to the principal town of Ancud to pick up supplies. Paved roads turned into gravel and cell phone signals quickly began to fade. It was a pathway into the past, a place without time.

Our final destination was Punihuil, a small community on the west coast of Chiloé. Punihuil is a isolated, but popular, tourist destination famous for its offshore penguin colonies. It is the only place in the world where you see the Humboldt and the Magellanic penguins coexisting and nesting side by side.

Fluke-Up Feeding in Hawaiian Waters

In the past few weeks our office has received numerous calls from concerned citizens about seeing a whale in distress.  The whale observed is spending long periods of time at the surface with its flukes extended above the water’s surface.  Some have conjectured that it is a whale using its tail flukes to sail; others have suggested it is attempting to cool down using its tail as a thermoregulatory device.

We believe a different hypothesis to be true.  The whale with the extended flukes is most likely a female humpback with a newborn calf. The mother is resting while still allowing her calf access to her mammary glands (located near the posterior portion of her body some 6-8 feet from her flukes).  By extending her tail into the air she is able to keep her body relatively close to the surface, allowing her to rest while minimizing dive depths for her young calf.  The calf is then able to nurse at will and expend less energy.

Underwater footage of humpback whales reveals penis extrusion

The research team was enjoying a lunch break on the water after completing a morning of transect surveys, when we noticed a nearby competition pod. We realized that the whales were headed towards us and decided to put our GoPro camera in the water to document the behavior. To our amazement, we had filmed something we never expected to see – one of the whales was swimming with its penis out!

A humpback whale penis can be up to 10 feet long and is normally concealed inside the animal’s genital slit. Seeing the penis extrude from this slit is a rare sight, which is why we were so astonished and pleased about the footage.

What is a “competition pod” or “comp pod”? If you have been on a whalewatch you may have heard this term before. It is something commonly witnessed in the humpback whale breeding grounds, such as Hawai`i.

Field Report from Panama

Panama is a thriving country with a diverse population and culture, a popular destination for travelers. Nickenamed “El Punte Del Mundo,” it the only place where you can see the sunrise and sunset over both oceans on the same day. Pro surfers have long traveled to the small town of Bocas del Toro known for its lush archipelago of islands, unique wildlife and terrific surf sites.
