We used passive acoustic monitoring to describe the vocal behaviour of sei whales in the Falkland Islands, between December 2018 and April 2019. We isolated more than 2000 low-frequency calls for manual classification, of which 510 calls with high signal-to-noise ratio were quantitatively measured. Five categories of stereotyped call types in the 15&amp;ndash;230 Hz range were described, some with multiple subcategories. These included some similar to previously described calls (e.g. downsweeps), but others that were novel in acoustic structure and frequency band. In the mid-frequency range, we documented a highly stereotyped, hierarchically structured and rhythmically repetitive song display. Songs were arranged in phrases with a structure composed of repetitive sub- phrases, and a diverse variety of sounds in the 1&amp;ndash;5 kHz range. Singing commenced in late February, despite the presence of whales and calls since early December, and continued through April. These acoustic properties and behavioural characteristics indicate that this is likely a male breeding display similar to songs and singing of other balaenopterids. This is the first detailed description of a song display for sei whales, highlighting the importance of the Falkland Islands.&lt;/p&gt;

Three archival acoustic recorders were deployed at sites in two regions for approximately one year each, in Hallaniyats Bay during 2011/2012, and the Gulf of Masirah during 2012/2013. Performance of recorders varied among deployments, but despite some challenges due to equipment failures we succeeded in documenting spatiotemporal patterns in the presence of humpback whales in a large dataset. Several key findings broaden our understanding of the Arabian Sea humpback whale population off Oman. There appears a strong seasonal component to the use of song by this population, primarily from November through May, which is congruent with the Northern Hemisphere breeding cycle and singing season. Throughout this period, singing was heard in both Hallaniyats Bay and the Gulf of Masirah, separated by approximately 400km, indicating that the population utilizes both of these regions. However, there was a much stronger presence in Hallaniyats Bay, with song heard nearly 24 hours/day during the peak months, and song detected simultaneously at multiple sites across the Bay. Previous boat-based survey data indicated similar trends, however, given limitation in the duration of this fieldwork the current acoustic dataset provides a more reliable indication of this population&amp;rsquo;s breeding related activity. This suggests that the Hallaniyats Bay might serve as a more important habitat for breeding activity than the monitored region of the Gulf of Masirah. There also appeared to be a subtle northward shift in distribution of detections as the singing season progressed, both within Hallaniyats Bay, and from Hallaniyats Bay to the Gulf of Masirah, suggesting a seasonal shift in distribution for singing males. During the summer and autumn months, very little song was detected, however sparse detections indicate that whales are present in both regions during at least some of this period. It is recommended that similar acoustic monitoring be conducted in all range states of the population to elucidate spatiotemporal distribution throughout the Arabian Sea.&lt;/p&gt;
