Live Boulder Osprey Cam

March 27:       Non-resident female visiting the nest. 
March 28:       Resident female returned. 
March 31:       Resident male returned. 

Nest Updates:

In late 2020 Xcel energy started a large solar project near the osprey nest. As part of an agreement between the City of Boulder and Xcel the nesting platform and camera were moved 100 meters North of the original location and away from any possible disturbance caused by maintenance on the solar array. We insured that the new nesting platform can be seen from the original location and all nesting material was moved so we don't believe that the resident pair will have any issues finding or nesting in 2021.

Viewing Tips:

The camera is solar powered and completely “off the grid”. Prolonged periods of inclement weather may cause temporary outages. If an outage occurs, please be patient and we will restore the live stream as quickly as possible. 

Background Information:

This video system was initially set up by Parks and Recreation staff at the Boulder reservoir for monitoring osprey. However, for the past several years Canada Geese have successfully defended that nest from osprey. In spring 2016, OSMP partnered with Parks and Recreation to upgrade some of the camera components and move the system to a more dependable Osprey nest near Valmont Reservoir. In 2017 OSMP staff installed a new HD camera for a clearer picture. With the help of other city departments, including Information Technology and Utilities, we now have the camera streaming live! 

OSMP wildlife staff have been monitoring the Osprey nest since 2011. Since then the nest has been successful every year, fledging a total of 17 young! 

When viewing the osprey, the male and female can be identified by their different markings. The female osprey has a “bib” of dark feathers on her chest, whereas the male has an almost completely white chest.


Monitoring of this osprey nest in past years has indicated:

  • March 20 - April 10: Adult osprey return to the nest
  • April 21 - May 9: Eggs laid and incubation begins
  • June 9 - June 24: Eggs hatch
    • Osprey eggs hatch in 36-42 days after being laid
  • Aug. 5 - Aug. 23: Young fledge
    • Fledging occurs 50-55 days after hatching
