Owl species

[Anne]

Okay, here's my owl question. We know that Hedwig is a snowy owl 
(although "she" is actually portrayed by a male owl, according to a 
British friend of mine in Manchester who is quite a birder). We also 
know that Malfoy has an eagle owl. So, does anyone know what kind of 
owl Pigwidgeon is? All I can remember about Pig is that he's tiny as 
owls go. Thanks!

either know the answer, or know how to find out)
