Forests across North America have seen a drop in the number of songbirds heralding the arrival of spring. To figure out why, biologists scour forests to capture birds and tag them with leg bands.
By going back to look for the tagged birds a year later, they can get a picture of how many survive from one year to the next. But the fieldwork takes untold hours, and capturing and banding can stress the birds.
A new paper lays out a quicker, gentler approach. It uses sound recorders and #AI to identify individual birds based on their song alone and track them over time.

Are deep-sea fishes truly circumglobal? This new study reports extensive cryptic (hidden) diversity in the Sternoptyx and Argyropelecus across the abyssal plains worldwide, with divergence time of tens of millions of years.

🕷️Spiders are incredible natural factories. They can spin up to seven types of silks (one for wrapping up insects for a late night snack, another to absorb shock, and more), and the same spider can often spin several of them. quantamagazine.org/how-spide…

Tall ice cliffs can calve faster than previously thought, but new observations suggest they are unlikely to trigger the runaway retreat feared in some projections of Antarctic ice loss.

Over half of vertebrate species are teleost fishes, with over 35,000 species. Why so many species? The answer is complex, but certainly involves the origin and turnover of multiple sex chromosomes, evolving at about the pace of speciation and extinction.

Rapid turnover of sex chromosomes is associated with speciation in Neotropical armored catfish Harttia (Siluriformes, Loricariidae)

Home decorating isn’t unique to Homo sapiens.
More than 40,000 years ago, bands of Neanderthals turned a spacious rock shelter in the mountains of Spain into a cozy home, fashioning wood into tools and windbreaks and burning it for heat and light.
That picture comes from a first-of-its-kind trove of Neanderthal wooden artifacts from a domestic space, found at a cliffside site called Abric Romaní, 50 kilometers west of Barcelona.

A Spinosaurus species uncovered in northern Niger appears to have been a wading predator of fish like its close relatives, but it lived as many as 1000 kilometers inland from the Tethys Sea. The fossil find may represent a third phase of evolution for this group of massive, fish-eating dinosaurs.

Greetings from the abyss! During the #Okeanos 2026 Cook Islands ROV Exploration cruise, we captured beautiful video of this cusk eel. Interestingly, despite their long bodies and eel-like shape, cusk eels are not "true" eels.
