The see-through glue with items inside can be cleared with bird boosters as well as by matching the item covered in glue with uncovered items on the board. Since you can not move the item covered in glue, you'll have to be able to make the match by moving the uncovered items.
The light pink glue can be cleared with bird boosters. On levels with TNT boxes the pink glue can also be cleared by detonating a TNT box next to the glue. To detonate the TNT box, make a match right next to the box.
