I wonder if they can explain why it's usually only the biscuits at the top of the pack that are cracked? (or is that only my imagination?)
I came across this guy who is analysing barn owl pellets as part of his research, and he can't find any (low population). Really, my heart went out to him, if only someone had warned him not to take on the project. Imagine having to make a public appeal to find what you need to research?
