Lesser Yellowlegs nest near Churchill, Manitoba, Canada. The egg on the far left of the frame is ‘pipped’, meaning that the chick’s bill has broken through the egg membrane and shell and will emerge within 24 hours. The chick in the middle of the frame recently emerged from the egg and is covered in fluid.
