“…Other than the summaries of old whaling records provided by Townsend () and Best (), the only published reports of humpback whales in Panama are as follows: a characterization of their vocalizations in Las Perlas Archipelago, Gulf of Panama (Oviedo et al . ); a photo‐identification study in the northwestern part of the Gulf of Chiriquí, located about 350 km west of Las Perlas Archipelago, looking at feeding area‐breeding area connectivity (Rasmussen et al . , ); and an analysis of the frequency of vessels en route to the Panama Canal that could potentially collide with whales (Guzman et al .…”

From 2003 to 2009, we surveyed Las Perlas Archipelago off the Pacific coast of Panama 53 times between the months of August and October to estimate abundance of humpback whales and to test for a migratory connection with populations from the southern hemisphere. We identified 295 individuals using photo-identification of dorsal fins, including 58 calves, and the population estimate for a single season was 100-300 solitary adults plus 25-50 mothers with calves; the estimated population of animals across all seasons using a mark and recapture model was over 1,000. Eight of the 139 fluke identifications were matched to whales in photograph catalogues from the Antarctic Peninsula and a ninth was matched to a whale sighted in Chilean waters; four of these nine individuals have also been sighted in Colombia. We conclude that Panama (Las Perlas Archipelago in particular) is an important calving area for humpback whales in the Southern Hemisphere. These data should provide a foundation for monitoring of population change and to increase awareness in Panama about the need to manage vessel traffic and tourism related to the whales at Las Perlas.

“…Márquez-Artavia et al (2012) sugieren que estas agregaciones evitan activamente las zonas de mezcla, donde el régimen de corrientes promovería la formación de turbulencia, con el fin de facilitar la preservación de energía durante la lactancia (Clapham, 2008). El canto en las ballenas jorobadas es el elemento conductual que resalta como aspecto crucial del cortejo y reproducción (Tyack, 1981;Clapham, 2000;Oviedo et al 2008;Smith et al 2008). Este comportamiento reproductivo define el uso de hábitat en esta área en particular.…”

“…Una vez corroborada la relación señal acústica/ ruido ambiental, se desplegó el hidró-fono para confirmar la presencia de ballenas cantando-la ocurrencia de vocalizaciones (todas las temporadas 2010-2013, n= 55), por un periodo de 5 min, donde adicionalmente se recolectaron registros de datos espaciales (lecturas de GPS), así como datos ambientales (temperatura superficial, mareas). Una vez confirmadas las vocalizaciones y en particular la consecución de cantos se procedía a grabar el ciclo de la canción y a tomar fotos de los individuos cantando de acuerdo con lo planteado en Oviedo et al (2008).…”

“…One such behavior is the singing of reproductive male humpback whales (Winn and Winn 1978). Humpback whale song has been documented in many breeding areas (Payne et al 1983, Payne and Payne 1985, Cerchio et al 2001, Darling and Sousa-Lima 2005, Eriksen et al 2005, Murray et al 2012, Oviedo et al 2008. Additionally, song has been recorded during migration (Norris et al 1999, Noad et al 2000 and on a few feeding grounds (Clark and Clapham 2004, Stimpert et al 2012, Garland et al 2013.…”

A key feature of humpback whale behavior, documented primarily on the breeding grounds, is the repertoire of the males' song. Song is made up of single units combined together into phrases, which are repeated to make up themes. A song consists of several themes sung in succession. This study qualitatively investigates the presence and structure of song recorded in the Gulf of Tribugá in the Colombian Pacific. Data were collected between June and September 2013, from which approximately 4 hours and 30 minutes of song were analyzed from five individual whales. Three distinct themes, always sung in the same order (theme 1-theme 2-theme 3) were identified. Theme 1 was the most predominant theme overall, and was present in each song session that was analyzed. The structure of each theme is described with accompanying spectrograms, and specific acoustic parameters further illustrate theme progression and characterize differences between whales. This study serves as the first published descriptive analysis of the song of stock G in this area, and suggestions are made for future directions of investigation. Research on humpback song is used as a part of the overall efforts of Macuáticos Colombia Foundation to educate the communities of the Gulf of Tribugá about the importance of conservation, and to advocate for stricter guidelines for safe whale-watching practices. RÉSUMÉLes baleines à bosse ont été observées dans le monde entier et elles migrent chaque année entre leurs zones de nourrissage dans les latitudes élevées et les aires de reproduction aux latitudes basses. Le chant des baleines à bosse est l'un des comportements lié à l'accouplement qui a été documenté sur les aires de reproduction. Ce chant est composé d'unités simples combinées dans des phrases et qui sont répétées pour composer des thèmes. Les chants sont composés de plusieurs thèmes et sont principalement émis par les mâles. L'étude actuelle a porté sur la présence et la structure du chant des baleines à bosse du G-stock enregistré dans le golfe de Tribugá dans le Pacifique colombien.Les données ont été recueillies entre juin et septembre 2013 à l'aide d'un hydrophone SQ26-08 au cours d'excursions en bateau qui se sont déroulées 3 fois par semaine. La structure du chant a été codée en utilisant Raven Pro 1.4. Environ 4 heures et 30 minutes de chant ont été analysées et les chercheurs ont identifié trois thèmes distincts qui ont toujours été entendus dans le même ordre. Le thème 1 dominait dans tous les enregistrements et était composé de répétitions de légères variations de l'expression 'ABABABAA'. Le thème 2 était composé de répétitions des unités 'F' et 'Bl', avec des variations de la phrase de multiples unités ré-pétées dans une rangée. Le thème 3 était composé de phrases ré-pétées d'une unité longue 'upsweep' tonale 'LU', suivie par une unité courte 'upsweep' tonale 'SU', parfois avec une unité 'downsweep' dans le motif. L'unité 'S' a été entendue pendant les transitions du thème 3 au thème 1. Le thème 1 a été entendu beaucoup plus fréquemme...
