A couple of weeks ago I had a great chat with Mary from the All About Penguins podcast about crested penguins, conservation, and field work. The episode is now available! Check out her website at www.lifeguin.com

Thanks! Let me know if you ever want to come out with us!
jeffwwhite.bsky.social
Thanks! Hopefully so. We're expanding to evaluate the rest of the region's eastern rockhopper colonies next season, so hopefully we'll have an even better idea of how to address this decline before they are gone.

New open access paper out! We evaluated the population structure and conservation needs for 3 crested penguin species in NZ. Read it here: journals.plos.org/plosone/arti...

Excited for the first day of presentations at #AOS2025. Looking forward to hearing about all the great science that's happening!

A Tawaki Project double-whammy! 🎉 After Myrene’s paper came out last week, we’ve now got a follow-up study highlighting just how adaptable tawaki are finding food at sea - a huge advantage in our rapidly changing world.

As always, Open Access and free to read:

After three years of hard work, @myrene_ventures has published her first scientific paper! 🎉 It suggests Tawaki might handle our changing world better than many other penguins.

It’s Open Access - go have a read! doi.org/10.7717/peer...

Happy World Penguin Day!

Steeple Jason Island. Home to the largest Black-browed Albatross colony in the world. I spent a week in March sampling albatrosses, penguins, giant petrels, shags, and more as part of our work to understand the dynamics of HPAI in the Falklands seabird community

Penguin counts, elephant seal harems, Canada goose sightings, and more!

Check out the report from the 2024 Bounty-Antipodes Expedition to see what all we were up to this season.

The big Bounty-Antipodes Expedition 2024 report is finally out!

It's jam packed with the info about the work we've been doing on the sub-antarctic Bounty and Antipodes Island including penguins (obviously), albatross, elephant seals - and more archaeological discoveries!

After over 5 months in the field I'm back in Ithaca and ready to begin processing samples for #stableisotopes and other dietary analyses. Stay tuned for field recaps from the Falklands/Malvinas and updates from the lab!

Another day and another tagged seabird… this time a Brown Skua at Saunders Island, Falkland. Ring ABU and with a geolocator (?). Anyone know anything about it? Also great to see it with a recently fledged chick. Survivors of the HPAI wave across the isles.

In the Falklands/Malvinas my focus is understanding food web dynamics for native predators/scavengers and their interactions with both native seabirds and introduced mammals through tracking, stable isotopes, and fecal DNA. Looking forward to a great season over the next few months.

Spent some time sampling and admiring the penguins of Saunders Island last week.
jeffwwhite.bsky.social
Would love to be added please!
jeffwwhite.bsky.social
I forgot to include the shags. But just look how stunning they are.
jeffwwhite.bsky.social
Of course I wouldn't be me if I didn't also post about all the fantastic penguins and shags I'm seeing (and also sampling) including a Northern Rockhopper that seems to have made a friend with one of the local Southern Rockhoppers. All this from just one island.

Last week I arrived in the Falkland Islands/Islas Malvinas for field campaign #2 of the season. This time I'm focused on the foraging ecology of scavengers on islands +/- introduced mammals. Lots of GLS to deploy on skuas and of course lots of stable isotopes to come!

Just a week ago we were packing and prepping for pick up from Antipodes Island. 2.5 months of exhausting field work flew by with this amazing team. Couldn’t ask for better people to study penguins with. Thanks for another great season @tawaki-project.org
