Aww, what cute glider pics!

We used to feed BML but it was always a battle to get my gliders to eat it. I hear a lot of good things about HPW.
Way to be a caring glider owner. Glad you found GC

and kudos to you for doing your research

Is the book by Caroline McPherson? That one is sort of old and outdated, so I would go by what you see on the board over that book, but it's better than nothing, and it was the ONLY book out for a really long time...I have a copy myself!
