obvious the second is maple, the last looks to be the shoot of princess pine, what are items 1 and 3?
Item 1 is a fern tip. I'd guess that at least 75% of the birds I've killed contain fern. Item 3 is some type of a tree bud, but I'm not sure which. The dominant tree species in the area were black birch, cherry and maple. My original thought was birch, but I'm not certain.
