Common Loons: Hatching
Peeps can be heard from inside an egg before the chick starts to crack it open (a process referred to as “pipping”) with its temporary “egg tooth.” The eggs hatch in the order laid, not at the same time. The chicks are covered with sooty black down which is often dry within an hour of hatching. While waiting for the second egg to hatch, the parent loon often takes the firstborn chick for its maiden swim, returning to the nest with the chick to incubate the remaining egg until it hatches. By the third week, the chick’s black down is replaced by brownish-gray down.
