Alcoa’s eagle nest is getting a little more crowded with the arrival of a second egg.
Liberty laid the egg about 5:30 p.m. Thursday — just four days after the first egg — in the nest on Alcoa Davenport Works’ riverfront property in Riverdale, Alcoa spokesman John Riches said Friday.
He said it is possible another egg could be laid. Liberty and partner Justice have produced two to three eggs each year since the spring of 2010. They first built the nest in 2009 in a tree along the Mississippi River.
"Our history with this, they usually are done laying in about a week of the first egg, which would be Sunday," Riches said.
Alcoa installed a webcam over the nest in 2010, and in early 2011, it launched a website and began streaming live video to share their eagles with the world. The nest and eagles can be seen at alcoa.com/eaglecam.
"It is a concern it is this cold when they're trying to keep the eggs warm," Riches said. "Hopefully, they have been doing a good job, but we won't know until it's time for the eggs to hatch."
The birds typically will bring new straw and grass into the nest ahead of the eggs, but they seem to have had trouble finding any, so Alcoa lent a helping hand.
"On Monday, we put out a couple bundles of straw on the property, and Tuesday the nest was full of new straw," Riches said.

Riches said the eggs traditionally have about a 35-day incubation period, which means they probably will hatch in early April. The young eagles could take flight in late May or early June.
The bald eagles have fledged eight babies, one of which did not survive, from their Alcoa nest.
In addition to more 20 million page views from fans across the globe, Eaglecam and its website also sparked a partnership between Alcoa and the Bettendorf Community School District. Using a grant from Alcoa, the district developed some learning modules that parents, students, teachers and the community are invited to use. They are found at the Eaglecam website.
