The second egg started the "pipping" process around 9 a.m. Saturday in a tree at the U.S. National Arboretum, an American Eagle Foundation spokeswoman reported. The baby was hatched around 6 a.m. CT Sunday.
The arboretum is operated by the United States Department of Agriculture.
The parent bald eagles are named "Mr. President" and "The First Lady."
The first eagle chick hatched Friday around 8:15 a.m. It took roughly 36 hours.

It's the first bald eagle pair to nest in this location since 1947.
A livestream has been provided by the National American Eagle Foundation and DC DMC.
But be careful not to get too attached.
Here's the warning posted underneath the live feed: "This is a wild eagle nest and anything can happen. While we hope that two healthy juvenile eagles will end up fledging from the nest this summer, things like sibling rivalry, predators, and natural disaster can affect this eagle family and may be difficult to watch." DC DMC has been recording livestream.
The first baby bald eagle was born Friday morning after a two-day-long hatch.
In 2014, this pair of mated bald eagles chose the most idyllic of nest sites within the United States' National Capital in Washington, D.C., nestled high in a tulip poplar tree amongst the Azalea Collection at the U.S. National Arboretum, which is operated by the United States Department of Agriculture.

The eaglets will be extremely dependent on their parents for the first several days, and over the next 12 weeks, they will learn to use their wings - an exercise aptly called "wingersizing." After 12 weeks, the eaglets will begin to take flight.
