Amazing changes have occurred in the robin nest in the past four days. I just got a chance to photograph the chicks after all the rain we've had recently. Compare this photo with the last one posted on May 28th (photo was actually taken on May 25). Not only has their body size increased quite a bit, but the chicks are now completely covered in pin feathers and their eyes are now open. Their mother always makes sure they're stuffed before she ventures out for her evening meal. One chick did slowly open his mouth for food when it saw me.
The chicks have gotten so large that they take up the whole nest. During the day, the mom comes and sits on the edge of the nest to keep watch. She only sits on the babies when it's stormy or overnight when the temperature drops.
