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.
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 🪶
Morphological change of lowland rainforest birds in Colombia!!
A long-term fan of all these authors in #ornithology 🙇🙇 @nataliaperez-a.bsky.social Ph.D. Results from the Colombian Resurvey Project!!!
Extended specimens (permanent chewing louse) provide another perspective of the long-term *enigma* of evolutionary and biogeographic history of _Sapayoa aenigma_… parasite linage revealed consistent extra-Neotropical origins! 🤯 #follow @julisoto.bsky.social for cool research on #ornithology
Our review outlining how we can better use climate data for understanding ecology and evolution— now published in TREE! I’ll give it a rundown after the holidays.

Wait, birds as truffle dispersers? What a cool research!

Thank you @oacevedocharry.bsky.social! Also great talk on using state-space models to estimate extinction risk from community science data, with promising results from a case study on the endangered Everglade snail kite.
I recommend checking out their paper! doi-org.lp.hscl.ufl.edu/10.1111/1365...
It went well!!!
@swamplily.bsky.social terrific talk! Many butterflies at risk but not enlisted in the Endangered Species Act need more research!
To help them:
1) maintain a pollinator friendly backyard
2) leave the leafs (they hibernate)
3) engage with conservation initiatives like @xercessociety.bsky.social
Today is #SNRE Research Symposium!!!
Honored to belong to this program and share some of my dissertation. Leveraging community science data we found similar patterns of estimates of probability of persistence than those from standardized monitoring!

💥BREAKING: Birds in a tropical pluvial rainforest of the Chocó have been quietly changing in morphology for 109 years. Some have shrunk, others grown. Tails grew longer, bills grew deeper. Even in forests with continuous cover, climate change may be rewriting evolution in real time.

Graphic abstract for easy visualization of the insect abundance and diversity found in the stomach of a Chordeiles nacunda. Pictured: stomach contents before preservation in ethanol 70%. A dashed pink circle highlights one of the 40 adult giant water bugs (Belostoma sp., Belostomatidae). Individuals of a giant water bug (Belostomatidae), a grasshopper (acrididae), and one Coleoptera accessioned in the Museu de Zoologia da Universidade de São Paulo entomological collection are also pictured (lower right).
Latest articles at the WJO: Insect richness in the stomach of a Nacunda Nighthawk. #ornithology www.tandfonline.com/doi/full/10....
Really excited to share this new article from the lab.
We synthesize the profound importance of movement and connectivity for conservation and provide a vision for future policy and management.
Let's work toward a well-connected planet for biodiversity and people:

Could we use community/citizen/participatory science data to estimate population extinction risk? Our results comparing the estimates from eBird and from a standardized survey suggest we can!!

Interrupting our doom-scrolling with a ray of ☀️ that was Orlando's @oacevedocharry.bsky.social wonderful seminar (to a packed room!) on his PhD work, from fusing standardized surveys + citizen science for improved population viability analysis, to global island biogeography. Check out his work!
Not great photos from my old phone, but here is @julisoto.bsky.social at #TheNat last night inspiring us all with her story of mystery, research, and intrepid women #nattalk #SanDiegoBirdAlliance
NEW PAPER: investigating uropygial gland microbiome in African hornbills. Microbiomes were similar among species but with slight differences by body region. Nest sharing influenced microbiota, suggesting that nest environment is key shaping them.

A conceptual diagraph comparing pros and cons of conservation actions at different ecological levels: species, assemblage, and ecosystem.
A Perspective from Belitz et al. suggests that focusing conservation and management actions at the assemblage level has multiple benefits relatively to purely species-focused or ecosystem-focused actions. go.nature.com/40F5MNa
