Nesting Diaries
A wet storm has settled in the area and cold wet and snowy conditions at the nest, very windy. No eggs currently.
April 2: Banded Female Displaced
The banded female has been displaced by the first female. Mating between the first female and the male has ensued. We hope to see eggs sometime around April 27.
Nest has been active for three years with the same pair, nick named Frankie and Johnny. Fledged three chicks last year successfully. No eggs currently to date, expected by Apr. 27, 2015
March 30: Banded Female Arrived
This female has a dark left eye and a band around her leg. She is the same female from last year that matches this United States Geological Survey Bird Banding Program Report (105 KB).
March 29: Male Osprey Arrived
The male arrived on March 29. Notice the lack of dark markings around the breast.
March 25: First Female Osprey Arrived
A female arrived on March 25.
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.
