Talks and informal lectures

I can give talks on a range of subjects concerned with butterflies, moths and birds. I am an Emeritus Professor of the University of Manchester, so I'm an experienced lecturer. I have all the background science, but appreciate that audiences require an entertaining as well as informative presentation. I have my own laptop and projector, requiring only a screen or a white wall. The talks are illustrated mostly with pictures shown on this site. See my homepage for e-mail contact to make a booking.

Talks currently available are listed below. They all last for about 45 minutes and I am happy to take questions afterwards.
