Bryde's Whale

Bryde's Whales: Agile Filter Feeder of Tropical Waters.

In the azure waters of the Azores, the Bryde’s whale (Balaenoptera edeni) emerges as a captivating marine presence. Characterized by its streamlined body and distinctive, elongated dorsal fin, the Bryde’s whale is an agile filter feeder, primarily relying on krill and small fish for sustenance. Known for its acrobatic displays, these whales gracefully breach and display tail slaps, showcasing their dynamic presence in the Atlantic waters.

Bryde’s whales are recognized for their tropical and subtropical habitat preferences, reflecting their affinity for warmer oceanic zones. Despite being one of the lesser-known baleen whale species, our scientific fact sheet delves into the intricacies of their feeding behaviors, communication patterns, and migratory habits. Join us on an exploration of the Bryde’s whale, uncovering the mysteries that surround this remarkable marine mammal and gaining insights into their role within the vibrant ecosystems of the Azores.

Behavior & Feeding

Vocalizations +

Known for producing short, yet powerful, low-frequency moans that resemble the vocalizations of other Balaenopterids. These sounds can vary in terms of frequency, duration, modulation, and the presence or absence of harmonics, depending on the geographic region and group size of the animals.

Foraging +

During feeding, this species exhibits abrupt directional shifts both above and beneath the water’s surface. It utilizes a diverse range of foraging strategies, including active lunge-feeding, which can attract seabirds and other pelagic predators, and surface skim-feeding. There have also been reports of this species using bubble nets to trap prey, and in the Gulf of Thailand, it has been observed using a passive feeding technique called “trap-feeding” or “tread-water feeding.” This technique involves the whale hanging vertically for several seconds with its mouth wide open at the surface, allowing fish to swim or wash inside, before lifting its head and closing its mouth.

Diet +

Bryde’s whales consume approximately 600 to 700 kg of food daily. Their diet includes krill, copepods, red crabs, and shrimp, as well as several types of schooling fish, including herring, mackerel, pilchards, and sardines. While it appears to have specific prey preferences, it is primarily an opportunistic feeder and will adapt its prey selection based on availability, geographical location, season, and year.

Communication / Echolocation +

They produce high pitched low frequency sounds (20-950 Hz), including moans, calls and sweeps, which varies in frequency, modulation, duration and whether harmonics are present. Its variation relies on geographic region and group size, though most Bryde whales have a call recorded in different locations which is below 60 Hz, last 1,4 s and is produced in extended sequences. A single whale can emit two calls at a time.

Identification +

At sea, they can easily be confused with other baleen whales, particularly sei whales, which overlaps in mid-latitudes. The distinguishing feature of the Bryde’s whale is a set of three parallel ridges on top of the head, in comparison to the one ridge in sei whales and the rest of rorquals. Of the two species, Bryde’s whales may also be more active on the surface, often with irregular breathing patterns and frequent changes in direction.

Distribution & Movements

Bryde’s whales are widely distributed, inhabiting tropical, subtropical, and warm temperate waters around the globe with temperatures ranging from 61°F to 72°F. They can be found in all oceans between 40° south and 40° north. While some populations of Bryde’s whales migrate with the seasons, moving away from the equator during the summer and towards the equator during the winter, others are residents and remain in one location throughout the year.
