Fairgrounds Osprey

This is one of several osprey nests in the county. In the spring of 2003, this osprey pair began nesting on a light pole at the Boulder County Fairgrounds and returned each year. In 2009, wildlife biologists moved the nest to its current location just east of the Cattail pond for the birds’ safety. The pair shifted to the new location with ease. Our biologists believe that the local surge in nests may be offspring returning to their previous habitat area.

In 2014 and 2015, a female osprey with a metal band around her leg was seen. We reported the band number to the United States Geological Survey Bird Banding Program and received the band report. This banded female osprey is not the resident female and may have lost her mate and/or was looking for a new partner.

In 2015, three osprey chicks fledged. In 2016, one osprey chick fledged. In 2017, three osprey chicks fledged. See the interactive timeline above for specific dates and other significant events.

Camera Setup

The camera is an Axis P5534 network camera that can pan, tilt, and zoom. A microphone is positioned under the camera to record sound. They are powered directly from a building that is approximately 750 feet away but the video and audio feed is transmitted wirelessly.

The nest is illuminated at night using an infrared light. The infrared light is powered using a battery that charges during the day with a solar panel. Infrared light is undetectable by osprey so it does not disturb them.

A lightning rod, two lightning suppression units, and shielded cables are used to protect the setup from lightning strikes.

A huge thanks goes to View Into The Blue, a company in Boulder County that specializes in streaming webcams, for helping us with our osprey cam setup. This is our sixth year running the camera and our first few years were plagued with technical difficulties. View Into The Blue was instrumental in helping us with our camera setup.

About Osprey


Opsrey 2012-06-03Osprey migrate far to the south every year to Central or South America. The male, female, and offspring all go their separate ways. The male and female migrate and winter separately but return to the same nesting site each year. Offspring usually remain at their wintering grounds for their entire first year before beginning a migration and nesting pattern. There are no markings to indicate which osprey is male and which is female, but the females are generally larger than the males. They show up around the first of April and complete mating and egg-laying within the first two weeks after both have arrived. They leave between September and October, after the chicks have fledged.

Other birds utilize the platform whether the osprey are present or not. Magpies and blackbirds have been spotted on the platform or camera when the osprey were on the nest. Smaller birds can nest in the nest material and are usually ignored by the osprey. One year we saw a Great Blue Heron perching frequently on the platform with no apparent disruption to the osprey


Osprey Eating FishThe osprey is the only local raptor that almost exclusively hunts fish. On rare occasions, they will eat squirrel or muskrat. Osprey will sometimes scout for fish from its nest. Once a fish is spotted, the osprey will drop down in the water fully submerged. Their dense and oily feathers allow them to come back out of the water and fly away. They are successful just over half the time on that first dive. Some of the public places you can see them fishing are: Fairgrounds lake, Twin Peaks golf course, Lagerman Reservoir, Izaak Walton Pond, Golden Ponds, and Pella Crossing.

The Nest

Osprey Fledge Returning to NestThe nest is mainly used for the osprey’s offspring. The nests have to be wide enough to support up to six full-sized birds. Osprey nests weight an average of 400 pounds and are amended yearly. No one knows why they collect all the different things that they do for their nest (including trash), other than to make the lining soft and to keep eggs from falling into voids in the stick nest. Osprey chicks only have a 50% chance of surviving their first year.
