Two eggs again this year!


eaglesOn Sunday, February 19th at 6:24pm, The First Lady laid the first (currently designated as DC4) of this season's 2 eggs. On Thursday, 2/23 at 4:26pm, DC5 joined the growing family. The eggs will be incubated by both parents, with The First Lady doing most of the overnight shift (see early morning image). The eggs will also be rolled periodically to help maintain an even temperature and to prevent the developing eaglet from sticking to the side of the egg shell. The incubation period is, on average, 35 days - so the expected "hatch watch" starts the week of March 27th. We are proud to continue our collaboration with the American Eagle Foundation (AEF), the U.S. Fish & Wildlife Service, DC Department of Energy and Environment, and Alfred State, SUNY College of Technology, on bringing to DC, the Nation, and the world, high-definition eagle nest cameras. Live sound is also captured this year and streamed through several new nest microphones! Check out the live-streaming video and audio at the AEF website. Locally, at the Arboretum, we have added a strategically positioned viewing scope to provide unobstructed views to the eagle nest from below our Azalea collection. So visit in person or via the web as the National Arboretum hosts these majestic animals and their growing family once more.


Spring has arrived early!



Spring has arrived early at the National Arboretum, and many of the early cherries such as the 'Okame' and 'First Lady' cherries are in full bloom, as are many deciduous magnolias. We have made the Cherry Blossom Self-Guided Tour available to you early because of the early flowering of the cherries. Take some time to visit the Arboretum and enjoy the burst of early spring blossoms!


Update: Temperatures plunged well below freezing the morning of March 4 and again the morning of March 5 at the National Arboretum. Early cherry blossoms such as those of 'Okame', 'First Lady' and 'Helen Taft' cherries were badly damaged, but the 'Yoshino' and weeping Prunus subhirtella 'Pendula' cherries were not yet open, so they will be blooming in the weeks to come.
