19.10.2018 – The Pilot whales of Madeira

During our cruises today, we were able to observe Bottlenose dolphins (Tursiops truncatus) and Short-finned pilot whales (Globicephala macrorhynchus). Those two species are both large delphinids. Basic facts and descriptions of those animals but also of all other cetaceans and marine wildlife occurring around Madeira can be found on our website: https://www.lobosonda.com/whale-watching/whales-dolphins/.

Especially the Pilot whales are known for their well-developed social structure but how many are there around Madeira? Which habitat do they prefer and what about their dive characteristics?

To answer that, we might take a quick look into some recent research results. Based on photo-identification and genetic data analyses, Short-finned pilot whales were studied in the archipelago of Madeira. It was found that the local population consists of resident animals, regular visitors and transient whales. There are less than 150 individuals staying in the islands vicinity continuously or coming here regularly. The total number including additional short-term visitors, which are here primarily in summer and autumn, is 300 whales.

Their preferred area of occurrence is located in the South of Madeira. In this zone, the activities include resting, socializing, foraging, breeding, calving and birthing. The researchers found out that the Pilot whales around here have relatively low diving rates and spend around 75% of their time during the day at the surface.

During every trip, we write down certain facts about our sightings and share this data as well as photos for scientific purposes. Herewith, we help to enhance the knowledge and understanding of those magnificent marine mammals in order to improve conservation strategies.
