“…In this study, hind age did not influence call duration. At the same time, a recent study of vocal aging of a marine mammal with laryngeal sound production, the North Atlantic right whale, Eubalaena glacialis, showed a remarkable increase of duration in calls of this species with age (Root-Gutteridge et al, 2018). The authors interpret these clear age-related voice cues as indicators of increased stamina or condition in older adults (Root-Gutteridge et al, 2018).…”

In female terrestrial mammals, vocal aging has only been studied in humans and pandas. In cervids displaying convergent sex dimorphism of vocal apparatus with humans, vocal aging is only investigated in males. This cross-sectional study examined acoustic variables of nasal (closed-mouth) and oral (open-mouth) contact calls of 32 farmed Iberian red deer hinds (Cervus elaphus hispanicus) aged of 4-18 years and their relationships with caller´s age, weight, social discomfort score (bites of other hinds on hind pelt) and body condition score (fat reserves). Decrease of fundamental frequency was associated with age in both oral and nasal calls, but more prominently in the nasal calls. An increase in call duration, peak frequency and power quartiles was associated with a higher degree of bites due to social aggression. Weight and body condition weakly influenced acoustic traits. We discuss that vocal aging of hinds parallels that of vocal aging in human females.

“…Nonlinear phenomena are observed in a variety of birds 25 , anurans 26 and mammals 27 , 28 , including marine mammals ( e.g. , manatee 29 ) and more particularly cetaceans (right whales 30 , 31 , killer whales 30 , 32 and humpback whales 33 ). They have been well described by a variety of authors 27 , 34 and include: (1) frequency jumps, that are characterized by sudden changes which moves up or down abruptly and discontinuously, and is different from continuous, smooth modulation 27 ; (2) subharmonics, that are additional spectral components and can suddenly appear at integer fractional values of an identifiable ( e.g.…”

Multiple pygmy blue whale acoustic populations in the Indian Ocean: whale song identifies a possible new population

Blue whales were brought to the edge of extinction by commercial whaling in the twentieth century and their recovery rate in the Southern Hemisphere has been slow; they remain endangered. Blue whales, although the largest animals on Earth, are difficult to study in the Southern Hemisphere, thus their population structure, distribution and migration remain poorly known. Fortunately, blue whales produce powerful and stereotyped songs, which prove an effective clue for monitoring their different ‘acoustic populations.’ The DGD-Chagos song has been previously reported in the central Indian Ocean. A comparison of this song with the pygmy blue and Omura’s whale songs shows that the Chagos song are likely produced by a distinct previously unknown pygmy blue whale population. These songs are a large part of the underwater soundscape in the tropical Indian Ocean and have been so for nearly two decades. Seasonal differences in song detections among our six recording sites suggest that the Chagos whales migrate from the eastern to western central Indian Ocean, around the Chagos Archipelago, then further east, up to the north of Western Australia, and possibly further north, as far as Sri Lanka. The Indian Ocean holds a greater diversity of blue whale populations than thought previously.

“…Several studies have noted differences in calls used by adult whales and calves, with dissimilarities in call structure, modulation and length, and a maturation of repertoire within the first year of life (Cartwright & Sullivan, 2009; McCordic, Root‐Gutteridge, Cusano, Denes, & Parks, 2016; Parks, Conger, Cusano, & Van Parijs, 2014). Development of acoustic repertoire both learned and innate (Brainard & Doupe, 2000; Janik, 2014; Janik & Slater, 1997; Poole, Tyack, Stoeger‐Horwarth, & Watwood, 2005; Root‐Gutteridge et al, 2018; Tyack & Sayigh, 1997; Wisdom et al 2001), mimicry (Abramson et al, 2018), and acoustic refinement with calf maturity (Cazau, Adam, Laitman, & Reidenberg, 2013; Root‐Gutteridge et al, 2018) has been reported in several cetacean species. A period of “babbling” has been noted in other whales species before the vocalizations are stabilized (Lenneberg, 1967; Lipkind et al, 2013; Marler & Peters, 1982; McCowan & Reiss, 1997), often accompanied by practice of manipulating airflow to produce the phonic sounds (Cazau et al, 2013).…”

Maternal behaviors of gray whales (Eschrichtius robustus) on a summer foraging site

The weaning period for gray whale (Eschrichtius robustus) calves is important for maternal instruction and learning. We examined observational and acoustic data from a foraging site for evidence of calf development and mother-young information transfer. Site survey data demonstrated an initial prioritization of calf protection by using shallow shoreline areas. Foraging in more open water was only noted in
