Peregrine Falcon Nest on the Dubuque County Courthouse — Live Webcam

On the roof of the historic courthouse building in Dubuque, Iowa, sits one of the most unusual nests in North America. A pair of peregrine falcons — the fastest birds on the planet — live here, raising chicks every year since 2017 right on the wall of the administrative building. The live webcam allows you to observe the lives of these majestic raptors in real time: how the female lays eggs, how the chicks hatch, and how the adult birds teach them to fly.

History of Peregrine Falcon Nesting on the Courthouse

The peregrine falcons appeared on the Dubuque County Courthouse building in 2017, and since then this place has become their permanent home for breeding. The nesting season lasts from mid-February to mid-June, and per clutch the female usually lays 4 eggs. The initiative to attract rare birds belongs to the county conservation director Brian Preston, who specially installed a wooden nest box on the roof. This decision helped the peregrine falcons establish a comfortable place for incubating chicks in an urban environment.

Dubuque County Courthouse: Architecture and Location

The Dubuque County Courthouse is located at 720 Central Avenue, between 7th and 8th Streets. This majestic structure was built in 1891-1893 and is a striking example of Beaux-Arts architecture with elements of Renaissance and Romanesque styles. The red brick walls of the building give it a strict, monumental appearance characteristic of late 19th-century public buildings. Nearby the courtyard is the historic Dubuque County Jail, which is no longer used for its original purpose but remains part of the city's historic heritage.

Peregrine Falcons: Record Holders of Speed and Grace

The peregrine falcon (Falco peregrinus) is a bird of prey known for its speed records in the animal kingdom. Both peregrine falcons living on the courthouse building have special identification bands: the female has a blue band, and the male has a red one. These tags allow ornithologists to track the birds' movements and study their behavior. Interestingly, peregrine falcons do not build nests in the traditional way — they prefer to use natural depressions, rocky ledges, or specially equipped boxes, as is the case with the courthouse building in Dubuque.

Nest Setup and Preparation for the Season

The nest box on the courthouse roof is filled with fine gravel and pebbles — exactly the material peregrine falcons prefer for nest building. To avoid disturbing the female during incubation, the nearest window to the nest was closed. The fact is that peregrine falcons do not like being near people, and the presence of humans could scare the bird and interfere with the natural breeding process. The wooden structure of the box provides necessary protection from the elements and good ventilation, which is critical for successful chick rearing.

Dubuque Surroundings: Mississippi River and Historic Downtown

Dubuque is one of the oldest cities in Iowa, located on the western bank of the Mississippi River. The city is famous for its hilly bluffs and rich historical architecture. The central part of Dubuque, where the courthouse is located, is a mix of 19th-century historic buildings and modern urban development. From the bird's-eye view where the peregrine falcons live, there is a view of the picturesque river bends and green hills characteristic of this region of the American Midwest.

How to Watch the Falcon Nest in Real Time

The online camera installed on the courthouse building operates in live broadcast mode and allows bird lovers to watch the peregrine falcons without having to travel to Dubuque. The real-time webcam shows everything happening in the nest: from the moment of egg laying to the first flight of the chicks. This is a unique opportunity to study the behavior of rare birds of prey in their natural habitat without disturbing their peace. The broadcast is available around the clock, and at different times of the day you can observe various aspects of the falcon family's life.

What You Can See on the Camera

The camera is aimed at a wooden nest box installed on the roof of the red brick building. The box is filled with fine gravel and pebbles, which the peregrine falcons use as nesting material. On the brick wall of the building, characteristic white bird droppings are visible — evidence that this bird habitat has been used for many years. In the left part of the frame, the adjacent area is visible: a parking lot with cars, a green lawn area, and a neighboring building. The live webcam provides a clear picture, allowing you to see the details of the peregrine falcons' behavior and changes in the nest as the season progresses.
