It is a capital plan for the children to keep a calendar––the first oak-leaf, the first tadpole, the first cowslip, the first catkin, the first ripe blackberries, where seen, and when. The next year they will know when and where to look out for their favourites, and will, every year, be in a condition to add new observations.
Again not a first, but we were privileged to see twin fawns (still sporting spots) walking through the horse pasture. We didn't see the mother, but I'm guessing she was waiting just a bit ahead and out of sight for us.
