Yellow Bird help

Hi all,
I stumbled across a couple of Yellow Birds while doing some cleanup work. I have not used them before and was looking for suggestions, location type and presentations that others use. I tried Googling them but really didn’t find what I was looking for. Can anyone shed some light on these?

Thanks,
Don
