Also an apparently new sp of Jewel Babbler in PNG.. #ornithology onlinelibrary.wiley.com/doi/full/10....

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 🪶

excellent new paper by Sam well summarized in this nice thread --- a TON of hard work went into testing these major hypotheses for range limits

Check out our new paper in @royalsociety.org testing mechanisms behind elevational range restriction in tropical montane songbirds! ⛰️🦜🌳 Backstory: when i first visited Central America in the early 2010's i was struck with elevational ranges of birds.. royalsocietypublishing.org/doi/10.1098/...

🦎THREAD: We just published something wild in @asn-amnat.bsky.social - lizards missing entire limbs not only survive, but some appear to actually thrive in the wild?! Let me tell you about the "three-legged pirate" lizards 🏴‍☠️ [Paper: www.journals.uchicago.edu/doi/10.1086/... ] (1/n)

Novel game idea: geoguessing but with eBird checklists 🌎 🦢

Our paper about the flow of nocturnal bird migration through Colombia is finally out today in #ProcB! Using weather radars operated by the #IDEAM, we found that low variability in wind underlies a pace of migration that is far more gradual than at temperate latitudes. #Ornithology 📡🪶🇨🇴 🧵1/10

We've just launched AviList! - the new unified global taxonomic checklist for the world's birds, developed through the Working Group on Avian Classification, including BirdLife, Cornell Lab of Ornithology, IOC and others @birdlifeglobal.bsky.social @birdsoftheworld.bsky.social www.avilist.org

My student Vanessa Perez is analyzing hundreds of photos of the Barred Fruiteater. If you have some, you can help her fill some geographic gaps. A cool story is unwrapping ⛰️🪶 Please share! #birds #ornithology #speciation #andes

🚨New paper alert!🚨 We show that hummingbird beaks have changed in shape & size since around WWII, driven by the rise of commercialized feeders! 🧵 📄 Paper: dx.doi.org/10.1111/gcb.... #ornithology #evolution #GlobalChangeBiology

Pleased to contribute some long(ish..) term data from Honduras as part of BioTIME 2.0: a terrific dataset ripe for all sorts of questions! onlinelibrary.wiley.com/doi/10.1111/... Also another wake up call as to the massive biological data gaps across equatorial Africa (and the tropics in general)..

It's that dreaded time of the year when one has to sort thru Willow and Alder Flycatchers. Primary tip spacing can make one's life much easier as outlined in Andrew Birch's and my article in Western Birds. Photo below from @evornithology.bsky.social static1.squarespace.com/static/54b9b...

Seemingly another one of Africa’s avian enigmas resolved!

Another birding paper! 🐦Where do the Nearctic landbirds that show up in Europe each autumn come from? We usually assume they come from NE populations, pushed off course by bad weather - but is that the whole story? #ornithology 1/3 www.nature.com/articles/s41...

Liquid whistles of Swainson’s Warbler.. fast becoming one of my favourite birds of the south eastern bottomland forests of the US..

Of which the epithet solala means only one wing! forever flying in circles.. Recent searches on the Nechisar plain to find it have still drawn a blank 🤔

Our recent paper made the cover of Ornithological Applications! We used Bayesian hierarchical mark-recapture modelling to understand demographic rates across an elevational gradient in Honduras. @amornith.bsky.social @seijones.bsky.social. Check out the paper: doi.org/10.1093/orni...

Whenever I hear someone say that ebird data sucks and is unreliable, it tells me that they are repeating something they were told 15 years ago, and that they haven’t read any of the truly groundbreaking methods developments that have made ebird one of the best macroecological datasets on earth

A lot of different people have been saying this in different ways.. for a long time

Anyone reading this know anything about this paper in Bill ABC?! Would love to hear more if so!

🚨Elite.. comparable to Cocha Cashu 1982 big day record!

200% all killer no filler

Big fan of the (new?) aberrant plumage tag on Macauley library - some enjoyable perusing of some avian weirdos tagging some of my own images.. search.macaulaylibrary.org/catalog?tag=...

cool paper alert authors compared modern eBird records to info from historical bird atlas from 1970s to infer distributional changes in Kenyan birds lots of cool results, including expansions in introduced sp (lots of green on maps below) admirably concise and clear as well

Still reigning 👸

🚨🦜🗻Check out our new paper on demographic rates of tropical birds along elevation in Cusuco NP, Honduras. Props to @mhcneateclegg.bsky.social for leading the analytical charge! @amornith.bsky.social See linked thread for paper coverage - here for a bit of background.. 1/5 doi.org/10.1093/orni...

🚨Kicking off my Bluesky life, I present our study in @amornith.bsky.social! We use Bayesian multi-species mark-recapture (CMR) models to assess avian demographic rates across an elevational gradient in Honduras! @samuel-ei-jones.bsky.social, @jsaracco.bsky.social 🧵(1/7) doi.org/10.1093/orni...
