Brandywine Rooftop Falcons, North View

A Skyscraper Above the Christina River

The Brandywine Building is an 18-story office tower at 1000 North West Street, raised in 1970 in the heart of downtown Wilmington, Delaware. Its broad, gravel-topped roof sits high above the surrounding blocks, giving a sweeping panoramic outlook over the Christina River waterfront and the Mid-town Brandywine district.

A Nest Box Watched Since 1992

In 1992, a U.S. Fish and Wildlife Service biologist installed a nest box on an upper floor after peregrine falcons began showing up around the tower. The Delaware Ornithological Society (DOS) has monitored the pair ever since, later adding a pair of exterior roof cameras — of which this north-facing feed is one — to follow the adults beyond the confines of the box.

What the Camera Watches For

Rather than the nest itself, this camera sweeps the open rooftop, where the falcons regularly land on vents, cable runs and roof-edge parapets to rest, preen or scan the skyline for prey. It is a favored spot for fledglings taking their first tentative steps away from the box each season.

A Citizen-Science Falcon Watch

The feed anchors DOS's Falcon Watch program, a long-running citizen-science effort that invites birders and residents of Wilmington to follow the resident falcons, nicknamed Red Girl and Trinity, throughout the nesting season.
