A mother Blue Whale (Balaenoptera musculus) with her calf slowly cruises a couple of nautical miles out off Ribeira Quente, São Miguel Island. Our first Blue of the year came with her calf, hopefully it is a good sign for the recovery of this endangered species in the Atlantic Ocean 🙂
What a month on the water here in São Miguel!!! Here is a perfect example of the biodiversity of cetacean species that visit the Azores Archipelago!
As for the previous months, Common Dolphins (Delphinus delphis) were the most sighted species, followed by another “resident” of our waters, the Bottlenose Dolphin (Tursiops truncatus). We observed again large aggregations, more than hundred individual strong, and smaller groups, most likely bachelor pods of juvenile males. Nursery groups were also abundant for both dolphin species and we spotted many calves, sometime less than one month old!
We had a couple of short encounters with a small group of Beaked Whales (Mesoplodon spp.) but sea conditions did not help to spot these elusive cetaceans.
Off-shore species such as False killer Whales (Pseudorca crassidens) and Striped Dolphins (Stenella coeruleaoalba) made us a surprising appearance too, reminding us how unpredictable is what you can encounter in the open Ocean. If you wish to have more information about these occasionally seen species check our previous posts about False Killer Whales and Striped Dolphins
Finally, we can say it: Spring is here and so are our migratory baleen visitors!!! After the vanguard of Humpback Whales (Megaptera novaeangliae), we started spotting rorquals almost every day. Check our last post about this amazing migration here !
Good news is that they did not come alone, but often with their young calves following! In this beginning of migratory season we already encountered two Fin Whale (Balaenoptera physalus) and a Blue Whale (Balaenoptera musculus) big mamas 🙂
Stay tuned to discover what the Ocean is planning for us in May!!!
