Remaining Hungry Humpbacks team visited @bas.ac.uk before flying south 💙 @kenneders.bsky.social @jlkershaw.bsky.social @eva-mariab.bsky.social will collect photo-ID, skin samples & track humpback whales to study their feeding ecology, pregnancy status & habitat use 🐳 ❄️ @seamammalresearch.bsky.social

This week the 2025 @wildwaterwhales.bsky.social team goes into the field! The team are journeying to South Georgia by ✈️ and 🚢, to study humpback whale foraging behaviour & feeding rates.

Here's project manager @sailorsteph.bsky.social packing & meeting UAV pilot Nico on the trek south 🐳 1

After FK ▶️

Six whales (3 ID'd females) went to Península Valdés calving ground, Argentina, for up to 3 months 🐳

Three males went foraging in the SW Atlantic, incl South Orkney & South Shetland islands, Scotia Sea &
Peninsula ❄️❄️

Nearly all foraged at the Patagonian Shelf in spring

Whales stayed locally for up to 2 months & mostly used the East #Falkland N/NE coast to breed & socialise 🐳🐳

🟩: Important Marine Mammal Area for right whales #IMMA
🔴: v slow movements, breeding/socialising
🟡: intermediate speed movements incl foraging
⚫: fast movements, travelling

Locations of 10 satellite-tagged southern right whales Eubalaena australis in the waters around the Falkland Islands (Malvinas) in 2022 using the model-predicted positions according to 3 behavioural states (BSs) generated with discrete-time hidden Markov models (BS1: slow and non-directional movements, indicative of high-use habitats; BS2: intermediate use areas, likely including foraging; and BS3: directed and fast movements, indicative of transitory habitats). The spatial extents of the 30 km buffer from the coast and the north-east Falklands (Malvinas) right whale wintering area Important Marine Mammal Area (IMMA) are shown

The #Falkland Isl are a high-use, critical habitat for southern right #whales! 🐳 Our new paper w Falklands Conservation studies local #whale habitat use & long-range movements @bas.ac.uk @hslesser.bsky.social #MarMam

Ten whales were satellite tagged in July 2022 1/3

A daily highlight is feeding this little guy each evening but I'm worried s/he is too small to manage through winter.. hoping they'll eat enough before it gets really cold. Any advice out there? #hedgehog

This is the third season @wildwaterwhales.bsky.social has studied #whales from small boats in Cumberland Bay. We regularly see humpback #whales particularly in the Bay entrance. Here are our sightings five years ago- excited to see what's there this season!

We're installing three underwater moorings in Cumberland Bay, South Georgia, to listen to local #whales & vessels from January 2025 🐳

Cumberland Bay is regularly visited by humpback, southern right whales & cruise ships @wildwaterwhales.bsky.social @southgeorgiaht.bsky.social @denrisch.bsky.social

Excited to take possession of our new multi-channel Soundtrap for underwater detection of #whales in South Georgia for the Sustained Monitoring project! 🐳 @wildwaterwhales.bsky.social
