"Can you help us identify a mystery lory in our collection?"
I was pleasantly surprised to find this email request from Donna Dittmann, Collections Manager and Museum Preparator for the Section of Genetic Resources at Louisiana State University Museum of Natural Science in Baton Rouge, Louisiana.
"Sure," I wrote back. "Send it to me and I'll see what I can do."

Count your chickens after they hatch, and they may do a little arithmetic themselves. Chicks only 3 or 4 days old manage an animal version of adding and subtracting, says Rosa Rugani of the University of Trento Center for Mind/Brain Sciences in Rovereto, Italy. Inspired by experiments with human babies, Rugani and her…

Those of you who go birding will know what I am talking about when I say that birds are so capable of reading human body language that they know when we are looking at them, which frequently causes them to hide from our gaze. However, this capacity has never before been scientifically studied in birds, until now, that is.
A newly published paper studied handraised, tame…

tetrapodzoology | April 4, 2009I've been seriously thinking about letting Tet Zoo lay fallow for a while, as I have a lot on right now and it's a horrendous distraction that I really shouldn't spend time on. Producing long articles like the one on the Sakhalin Island carcass are very satisfying, but they soak up a lot of time. The day job keeps me busy, well, all day, and academic and editorial commitments keep me busy most nights - and this is on top of having a new baby in the house. Today I made a special effort to just go out on my own and waste time looking at stuff in shops, purely because I feel immense pressure to…

tetrapodzoology | March 31, 2009
I used to receive random unsolicited emails from an individual who strongly promoted the idea that birds could not not not not be dinosaurs, that the entire dinosaur family tree was screwed up beyond belief, that 'dinosaurs' had evolved from random assorted diverse archosaurs, that cladistics was rubbish, and that all mainstream palaeontologists were idiots.
For some reason, the study of dinosaurs attracts people with strong 'fringe' beliefs: this must be a by-product of popularity, as you don't get this with temnospondyls, fossil ostriches, Eocene primates, corals or sea jellies (at least…

Birds in Science and Technology
Researchers have discovered the first direct evidence that exposure to stress in young birds affects the way they react to stress when adult. Exposure to stressful events soon after birth has significant effects on a range of physiological and behavioral responses later in life. Previous work in mammals has been unable to work out whether this is due to raised stress hormone levels produced by…
