Dear MARMAM community,

My co-authors and I are pleased to share our recent publication in the
Journal of the Marine Biological Association of the United Kingdom.

Abstract.
Here, we report the first sighting records of Bryde's whales in Nicaragua.
Four sightings were made in 2022 during boat-based surveys off the
southwestern coast of Nicaragua. Photo-identification, distributional data,
dive times, and behavioural information were collected, and environmental
parameters, including sea surface temperature, were measured for each
sighting. Sightings included calf and non-calf groups displaying travelling
(n = 1; 25%), milling (n = 1; 25%), and suspected feeding (n = 2; 50%)
behaviours. Approximately 4 h of focal following allowed the calculation of
short and long breath intervals. Based on our observations , the
individuals were suspected of feeding in the area, based on the presence of
feeding birds, feeding humpback whales, relatively high time-lagged
chlorophyll-a, and observed general behaviours. Our findings indicate that
this species may occasionally visit Nicaraguan coastal areas in search of
feeding opportunities, and could represent a possible range extension of
the Eastern North Pacific stock.
