Cabo Pulmo and the Capes Region, 2/11/2020, National Geographic Venture
National Geographic Venture
After having crossed the Tropic of Cancer during the night, National Geographic Venture started a new day inside the tropics; many of us early risers admired a spectacular sunrise that colored the clouds and sea with beautiful tones or red, orange and pink. Not long afterward, we arrived at Los Frailes, just outside of the Cabo Pulmo National Park, and dropped anchor to get ready for a great morning of water activities. Everyone who went snorkeling had a great time watching many different kinds of fish, equinoderms and corals. Some of the favorites where the convict tangs, the yellowtail surgeons, and of course, the king angels. Several species of hard reef-building corals in good health were seen all around, as well as some California sea lions. Amy Malkoski and I went scuba diving with a local operator in order to take underwater video for everyone on board. We went to the El Vencedor shipwreck, a former tuna purse-seiner that sank several decades ago after hitting a rock and well known for the abundance of fish life around it. Today, El Vencedor did not disappoint us! Even before we reached the bottom, we spotted the first of many bull sharks that were a continuous presence throughout the dive. At times, we were able to see up to eight different sharks swimming together all around us and allowing me to take video of their elegant and magnificent beings. In today’s world, when we have already lost 90 percent of the planet’s requiem sharks, it is an authentic privilege to see those most important elements of the marine environment. The mere presence of so many top predators is a good measure of the success of Cabo Pulmo, a very encouraging example of how Mother Nature can recover when we give her the chance.
During the rest of the day we sailed through the Capes region, which is one of the most important breeding and calving grounds of humpback whales in the North Pacific; we saw the first ones even before we weighed anchor, actually! Throughout the evening, we watched numerous humpbacks, several of them in tight groups of males competing with each other in order to gain the right to mate with a female. We saw many whale body parts out in the air, including 15-foot-long pectoral fins, flukes, heads and multiple breaches – even a couple of whales that breached together not far from the ship. A colorful sunset marked the end of our last day inside the beautiful Sea of Cortez. What a day!

Beautiful Almejas Bay was the stage for our whale watching performance today. We moved on fiberglass outboard boats called pangas with local pilots. As we reached the mating area, some 60 whales were seen doing amazing things, like spyhopping, breaching, rolling, fluking, and more. We stayed with the whales the whole morning, and, of course, guests and staff took thousands of photos of these gentle giants. We finished this phenomenal day with relaxing walks on the dunes of Magdalena Island in a location known as Sand Dollar Beach.
The day began with a lovely stretch class led by our wellness specialist as the sun rose over Bahia Magdalena. National Geographic Venture made its way into Puerto San Carlos, and we watched pelicans swoop and dive near the shore. After a hearty breakfast, we loaded into buses and made our way to Puerto Adolfo Lopez Mateos. The plaza at the docks is always a festive, colorful place, and we were greeted by Mexican music and traditional dancers. One couldn’t help but dance. Excited, we loaded into the pangas of local, certified whale watching guides and set out toward the mouth of Boca de Soledad. On our way, we slowly passed by the mangroves that play such an important role in the immense amount of life found within Bahia Magdalena. Magnificent frigatebirds roosted in the upper branches while double-crested cormorants were seen diving and fishing in the shadows of the trees. We headed out farther into the bay and began to see blows. Several adult gray whales and a few cow/calf pairs dove and logged and blew and swam in the vicinity of our pangas for the rest of the morning…some off in the distance and some close enough to cover our glasses with spray. It was such a special experience to be in this part of the bay where so many pregnant whales come to give birth. All that whale watching caused us to work up an appetite. We went to a restaurant for a delicious, authentic Mexican meal while Los Coyotes, a musical group, serenaded us with traditional tunes. Full and happy, we returned to the plaza to ready ourselves for our afternoon whale watching tours. It’s amazing how much difference just a few hours can make while observing nature. On this trip, we saw less whales, but those we saw came much closer to the boats. The trip ended perfectly with around ten bottlenose dolphins playing across the bow. We returned to National Geographic Venture with great stories and great recaps from our staff to remind us of all the beauty we witnessed that day.
Last night, we rounded the cape that forms the southern tip of the Baja California Peninsula and began making our way north through the open waters of the Pacific towards Magdalena Bay. The norteño winds were blowing, and the sea conditions were quite different from the flat, glassy waters we experienced earlier in the week. After breakfast, as National Geographic Venture advanced over the swells, a masked booby flew alongside us for several minutes, affording us excellent views of this beautiful seabird. Over a third of our guests this week are part of a group organized by The Nature Conservancy (TNC), and this morning we enjoyed talks from two TNC guest presenters. Tom Dempsey’s talk, “Building Ocean Conservation Solutions for Scale,” focused on actions his team is taking to reduce two different types of adverse human impacts on whales – entanglements in fishing gear and ship strikes. TNC has partnered with fishing communities along the California Coast to create a robust recovery system for lost crab fishing gear, the loose vertical lines of which are one of the more common entanglement threats to whales. Containerships striking whales are often an invisible cause of whale mortality, and Tom also described his team’s vision to bring a “whale safe shipping” certification to the international container shipping industry. Having such a standard would recognize compliance with ship routes and speed restrictions and would allow merchandisers to apply market pressure to reward good behavior. Soon after Tom finished fielding questions from guests, the expedition leader made an exciting announcement over the ship’s public address system: a killer whale had been sighted near the ship! National Geographic Venture slowed down and turned around to allow guests to come out to the bow to enjoy this sighting. The very tall, angular dorsal fin was indicative of an adult male killer whale, and it stayed near us for some time. Our position at the time was just offshore of the southern tip of Isla Margarita, near the Rehusa Channel, which forms the southernmost entrance to Magdalena Bay. Although gray whale calves and their highly protective mothers are inside the shallow waters of the bay, killer whales very rarely enter Baja California’s gray whale lagoons. Although we don’t fully understand why, our naturalists shared theories of why this might be. Once we got underway again, TNC’s Frank Hurd shared a great talk titled, “Sustainability through Partnership – Working with Fishing Communities to Ensure a Better Future for Marine Ecosystems & Everyone that Depends on Them.” Frank has worked closely with local fishing communities here in Baja California Sur and has helped them use scientific tools to create size limit restrictions that can protect their marine resources and future livelihoods. As we witnessed yesterday in Cabo Pulmo, the key elements to efforts like this being successful are initiation and ownership of regulations from within the community. TNC and its partners are working in many other geographies around the world to scale this community-driven, relationship-based approach to marine conservation. Over lunch in the dining room, we breathed a sigh of relief as National Geographic Venture passed through La Entrada, the principal opening of Magdalena Bay to the Pacific. The seas calmed as we entered protected waters and saw our first gray whales of the trip. We enjoyed a presentation from naturalist Rich Kirchner on the “Birds of Baja” before anchoring just offshore of one of the narrowest parts of Isla Magdalena. Excited to stretch our legs and explore this new environment, we loaded Zodiacs to shuttle guests to the beach. In front of us, a sweeping expanse of barchan dunes formed an isthmus connecting Isla Magdalena’s rugged mountains of metamorphic rock to our south and north. These rocks are exotic terranes, accreted onto the edge of the continental plate millions of years ago. Ocean currents then deposited huge quantities of sand in this area, and these rocky outcrops were connected by dunes to form the barrier islands that separate Magdalena Bay from the open Pacific. We broke into smaller, naturalist-led groups to explore this spectacular landscape of shifting sands. We saw shell middens left behind by inhabitants of this area thousands of years ago, fine grains of powdery sand blowing and cascading over the crescent-shaped dunes, succulents that are slowly managing to stabilize their dynamic environment, tracks of kangaroo rats, lizards, foxes, and coyotes, interesting plants such as satiny locoweed and Magdalena twinevine, and a loggerhead shrike perched atop an island of desert thorn. We crested the dunes and took in the sweeping views of Sand Dollar Beach and the waves of the open Pacific with all our senses. Now it was time to beachcomb! In addition to hundreds of sand dollar skeletons – and a few sand dollars that were still alive – we found an abundance of sea turtle ribs, crabs, bird skeletons, and shells left behind by mollusks such as cockles, scallops, and pen oysters…and much, much more. Exhilarated by the beauty of this special place and the joy of exploration, we eventually walked back across the dunes towards National Geographic Venture , glowing in the soft light of the late afternoon sun. After cocktail hour and evening recap, the hotel team treated us to a Mexican fiesta in the dining room. We enjoyed ceviche, guacamole, tamales, and enchiladas mineras. We somehow managed to save a little space for delicious tres leches cake, and then we returned to the forward lounge one last time for a presentation by naturalist Megan Wehrenberg on mangrove ecosystems. Today was yet another full day, and we are excited for the opportunity to spend time searching for gray whales tomorrow!
