Dr Steve Portugal, Animal Behaviour and Physiology

Had a fun (and very busy) week on Biotweeps. Covered a range of topics, including Siamese Fighting Fish, Eggshell Physiology and Colour, Avian Migration and Moult. The favourite topic I think was Avian Vision. Lots and lots of questions about that topic. Was excellent. The week has been storified, can can be found here:
