Le Savior Trophy
Rescue 100 baby birds.
Baby Birds form one of the objectives you can collect across levels, they appear as a Baby version of the bird you are currently flying (e.g. Penguin and Kiwi etc.) suspended in the air by coloured balloons. These are generally placed in your flight path so there should be no need to search for them. If you go about collecting most of these in every level, you should earn this trophy at some point between levels 7-10.
