Of course, Pterodroma neglecta had to be among the understudied seabird species. 😜

On the other hand, everybody got surprised to see P. inexpectata there!

Hey seabird folks - have you ever thought "*ANOTHER* talk about ?!" So did we.

So we reviewed 3000 conference abstracts to see which species get the spotlight. Huge work from @ingridpollet.bsky.social with me and @seabirdsentinel.bsky.social

Lavers b c d Highlights • Decade-long review of >2,950 seabird conference abstracts. • Over 30% of seabird species are rarely or never featured at scientific conferences • Several seabirds listed as Critically Endangered have received little or no attention. • 16 seabird species are over-represented in conferences. • Southern Hemisphere seabirds require greater research attention.

Out now in Biology Letters, my latest paper tackles an apparently simple question: how many characters are needed to reconstruct a phylogeny? TL;DR: in most cases between 100 and 500, more than a substantial portion of morphological datasets, but the story is more complex... doi.org/10.1098/rsbl...

💥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.

I had missed this well written rebuttal on the purported Ivory-billed Woodpecker rediscoveries; these passages in particular are gold:🪶
academic.oup.com/bioscience/a... #Ornithology
They are reported not by random, casual observers but typically by select enthusiasts deeply committed and emotionally attached to the idea of the ivory-billed woodpecker's survival against all odds. These individuals have often dedicated years to the hopeful pursuit of clues supporting the species' continuing existence. Therefore, as one of the former searchers admitted in hindsight, “many searchers may have been subconsciously biased and, as a result, not sufficiently cautious in their identifications under field conditions” (Sykes 2016). The purported sightings invariably occur in flooded southern swamp forests deemed by the dedicated enthusiasts as the ideal habitat for the species and less often, if at all, frequented by other observers (Hill 2007, Collins 2019). The vastness and inaccessibility in the descriptions tend to be exaggerated: “Alligators, wild boars, and venomous snakes are abundant, and there is a danger of heat stroke during the summer and hypothermia during the winter” (Collins 2019), being a description of an area of less than 100 km2, a mere 40 kilometers (km) away from New Orleans, the most populous city in Louisiana. The LSU Museum of Natural Science in Baton Rouge, historically one of the most vibrant ornithological centers in the Unites States, is about 145 km away. An area of 100 km2 would by no means be vast enough even for a single ivory-billed woodpecker, let alone a breeding population, to hide in for long. Meanwhile, there are abundant eBird reports of other bird species from the same area (Pearl River swamp), with the widest gap between adjacent observations of pileated woodpeckers, as an example, being less than 5 km (figure 3).

Eu moro no país que passou por 20 anos e assassinatos e torturas da ditadura militar. O país onde mais se mata ativistas ambientais. O país do Chico Mendes, do Bruno Pereira, da Dorothy Stang e da Marielle.

How should we frame and name the diversity of information linked to specimens in natural history collections? Researchers provide an overview of the most commonly used key terms, examine their conceptual interrelations, and present a literature-based survey of their usage.

Interesting question arose during an email conversation about museum labels:

Can we assume QR codes will still be a thing in the near future (≈ next 50 years for museums)?

I've got QR codes on all my labels. Be interesting if they needed replacing some day.. 🧪
