Huge News from the Western Amazon: it's the year 2025 and we are still describing entirely new, strikingly-distinctive large-bodied bird species! Behold Tinamus resonans sp. nov. the Slaty-masked Tinamou mapress.com/zt/article/v... #Ornithology @tetzoo.bsky.social 🪶

Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.

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.

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

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. @scottishseabird.bsky.social? #Seabirds

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.

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

Somehow 2.5 months on Antipodes has come to an end. We said goodbye to that stunning island and the incredible birds that call it home, and sailed back to the South Island. Hopefully expanding the work to other islands next season. 🐧🇳🇿#seabirds

Ever wonder what a penguin colony sounds like at night? This is from our southern study colony on Antipodes. Our camp is located about 50 ft away so we get to hear (and smell) them all night long.

Crèching is imminent for the erect-crested penguin chicks. But being too big to fit under dad means that they are now exposed to the sun. On bright sunny days the colonies can get very warm, so the chicks resort to rather dramatic panting to stay cool. I’m sure they are relieved when night comes.

Jeff White @jeffwwhite.bsky.social · 10/12/2024

This big erect-crested penguin chick has figured out how to game the system. That’s not its dad beside it. This chick belongs to a neighbor. Over several days we watched it get fed by its mom and then waddle over to the neighbor and successfully get fed a second time by another chick’s mom.

It’s been a very rainy few weeks here on Antipodes. Many of the erect-crested penguin chicks are now too big to hide from the rain under their parents. They don’t seem thrilled by this new development.

We often stop for a break in this gully when crossing the central plateau of Antipodes Island. Thjs time we had the privilege of being visited by a very curious pair of skuas. They were busy testing our boots and packs for at least 20 minutes before we had to continue our walk.

Eastern Rockhoppers face a bleak future. Since the 1940s they have declined by 90% or more across their New Zealand range. Entire colonies have disappeared. Seeing the first chicks of the season really reminds me that they aren’t gone yet so we should keep fighting to protect them and their habitat

The erect-crested penguin chicks are growing fast. While the males stay home keeping the chicks warm and safe from skuas, the females go out to sea to find enough krill to feed themselves and their chicks. It looks like this chick’s mom is doing a great job so far.

You never quite know what might pop up on the island. This Canada Goose showed up last week in the penguin colony. They are a common introduced species on mainland NZ (it didn’t fly here from North America).

In our main study colony on Antipodes Island, many nests now have tiny chicks waiting for mom to come home and feed them some krill.

The erect-crested penguin colonies on Antipodes Island are getting busy. Females are returning from a quick foraging trip at sea, which always calls for an energetic greeting. Just in time too as the chicks are to starting to hatch.
