Just the hint of a rainblow. Whales sleep differently to humans, with only half of their brain asleep, so that they remember to breathe, otherwise they would drown. 12-13 m. Baird’s beaked whales are deep-diving cetaceans which belong to a group called the ‘beaked whales’, named for their elongated beaks. They can become entangled in many different gear types, particularly in gear associated with the California/Oregon drift gillnet fishery. At the surface, they will remain logging (resting), continuously blowing, breaching, or displaying various other behaviors (e.g., spy-hop and slap flukes and flippers) between dives for as long as 14 minutes. They often assemble in tight groups drifting along at the surface. A Rare Baird’s Beaked Whale Sighting! Other coloration, such as a greenish-brown shade, may be the result of whale lice infestation or diatoms (a type of algae) on the skin. Males appear to have a lower mortality rate and mature more quickly than females. They are quite elusive and keep out of the way of ships, though sometimes they bask at the surface, unless startled. Read the final rule on the taking of marine mammals incidental to commercial fishing operations (PDF, 10 pages). According to the IUCN Red List, there are 1,100 Baird’s beaked whales in the eastern North Pacific, and about 7,000 individuals in Japanese waters (5,029 off the Pacific coast, 1,260 in the eastern Sea of Japan, and 660 for the southern Okhotsk Sea).

Baird's beaked whales have a large, slender, long, robust body with a relatively small, rounded, triangular dorsal fin that is located about two-thirds of the way down their back. Their pectoral flippers are short, round, and untapered, folding against their body. They have a small dorsal fin located two thirds down the body, a blowhole that is crescent shaped, and a forehead with a melon-like shape, from where its slender beak projects. There is no precise data about this whale’s mating system, but they occur in groups with a number of males, and in large groups with both male and female adults. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. No data … Baird’s beaked whale: dark brown, with irregular white patches on the belly Deep-diving small whales like Baird's beaked whales use sound to feed, communicate, and navigate in the ocean.

The body of Baird’s beaked whale is round and tapering towards the head and tail. The name "beaked whale" is from the way the rostrum, or long snout, tapers to a tip. Because beaked whales are hard to distinguish in the wild, much of the information about them is generalized to the entire genus. Baird’s beaked whales may die after ingesting fishing line, balloons, plastic bags, plastic pieces, or other debris which they can mistake for food. Baird’s beaked whale is found in the east from the southern part of the Gulf of California, to the Bering, Japanese and Okhotsk Seas in the west and in the temperate North Pacific. Researchers and collaborators at the Alaska Fisheries Science Center have conducted acoustic monitoring to record the sounds that Baird’s beaked whales and other cetaceans receive and the sounds they produce. Killer whales are the primary predators of Baird’s beaked whales. Baird's Beaked Whale Wikipedia article -, 2. They also have a curved head with a bulbous forehead (known as a melon); a distinct, long, cylindrical beak; a curved mouth line; and a crescent-shaped blowhole. Little is known about Baird’s beaked whale reproduction. Beaked whales have shown behavioral responses to sonar and are thus susceptible to the impact of military activity in the area. To understand the health of marine mammal populations, scientists study unusual mortality events. seismic airguns used for oil and gas exploration. Thus, data are insufficient to estimate population trends. In the United States, they inhabit waters off the West Coast from California to Alaska. They will move farther offshore during winter and spring when sea temperatures have decreased. …, NOAA Fisheries, upon request from the U.S. Navy, has issued regulations pursuant to the Marine Mammal Protection Act to govern the taking of marine mammals incidental to the training and testing activities conducted in the Northwest Training and Testing…, NOAA Fisheries has issued an incidental harassment authorization (IHA) to Lamont-Doherty Earth Observatory (L-DEO) to incidentally harass, by Level A and Level B harassment, marine mammals during seismic activities associated with a marine geophysical…, NOAA Fisheries has issued an incidental harassment authorization (IHA) to Lamont-Doherty Earth Observatory of Columbia University (L-DEO) to incidentally harass, by Level A and Level B harassment, marine mammals during seismic airgun activities…, Stay informed of all the latest regional news around NOAA Fisheries.

With declining numbers and emphasis on other species, the number of B. bairdii caught has diminished (Watson, L. 1981). Baird’s beaked whales, sometimes called “giant bottlenose whales,” are the largest members of the beaked whale family (Ziphiidae). Females reach lengths of about 40 feet (13 m), while males are slightly smaller at about 35 feet (11.5 m). This whale can be identified when it surfaces to breathe; its head comes out of the water at a steep angle allowing the bulging forehead and beak to be seen clearly.

Baird's beaked whales in the Aleutian Islands. It never gets old seeing an animal of that size coming completely out of the water! Predation from killer whales may also be responsible for some of these scars. Baird's beaked whales, however, are some of the most commonly sighted beaked whales because of their social behavior and large body size. Sources of sound pollution include noise from shipping vessels, military sonar, and sonar used for seismic airguns used for oil and gas exploration. In 2016, we issued technical guidance for assessing the effects of anthropogenic sound on marine mammal hearing.

Whaleopedia was developed with initial funding from VISA. These whales are among the least studied and most mysterious of all cetacean families. NOAA Fisheries conducts research cruises to collect information on beaked whale stocks, such as habit preferences and feeding ecology. According to Wikipedia, estimates for Baird's are of the order of 30,000 individuals. Typical dives last from 11 to 30 minutes, but beaked whales have been recorded diving for more than an hour; the longest known Baird’s beaked whale dive lasted 67 minutes.

Giant bottle-nosed whale, North Pacific bottlenose whale, Northern four-toothed whale. Females typically give birth once every three or more years, and do not have a post-reproductive stage. Noise and chemical pollution are further threats, as well as climate change, as it is predicted to change the marine environment. Baird’s beaked whales mainly eat mackerel, octopi, squid and sardines. Both whales reach similar sizes, have bulbous melons, and long prominent beaks. Identification is further complicated by their relatively small body sizes, elusive and shy behavior, and inconspicuous blow. They and Arnoux’s beaked whale may well represent different populations of the same species; only through the comparison of specimens can this be confirmed or disproven. Internet Explorer lacks support for the features of this website. Younger whales may have a comparatively paler … Commercial whaling, described a new species (Berardius minimus) of beaked whale of the genus Berardius found in the North Pacific Ocean. Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that can have implications for human health and welfare. Adult males may seem lighter because of heavy grayish-white scarring from scratching and raking other males with their small front teeth. Whales stay at the water’s surface when they sleep, their blowholes above the surface. NOAA Fisheries estimates the population size for each stock of Baird’s beaked whale in its stock assessment reports. Baird's beaked whales in the Aleutian Islands.
