Osprey Cam: The Osprey Return

Osprey have been observed daily since April 20 at an Arboretum nesting platform.

COVID-19 Update: All members and visitors need to make a reservation in advance of their visit to the Minnesota Landscape Arboretum. Find updates and information here.

A pair of Osprey were spotted at the nest on Tuesday, and they’ve been returning daily. We hope they’ll nest here for the season.

Our new Osprey Cam is finally live streaming Osprey. A pair of Osprey started visiting the nest on April 20, and they’ve been spending time there each day, but the female hasn’t laid any eggs.

This is a different pair than the couple that previously nested in this location. Vanessa Greene, the founder of Twin Cities Metro Osprey Watch identified the male osprey earlier this week by observing his band. “The male is a new one, MS, who is three years old and was hatched on a nest nearby in Carver Park,” Greene wrote April 21 on her blog and the Twin Cities Metro Osprey Watch Facebook page. “This will be his first breeding attempt. The female is un-banded, and I believe she is a new female.”

Thanks to the Garwick Family Memorial Fund and Jo Frerichs for generously sponsoring the costs of the live Osprey Cam, we installed and repositioned a new camera in mid-March. Before the Osprey came, we observed visits from Eagles and other birds.

An Eagle has visited the nest periodically since late March. (Eagles can be predators for Osprey, so hopefully this Eagle has moved on for the season.)

The Osprey Cam nest at the Arboretum is one of three Osprey nests located on man made platforms at the Arboretum, and it’s part of the Three Rivers Park District’s successful Osprey Reintroduction Program.

Osprey nest on elevated locations in open areas near water–away from tree lines to avoid predation from Great Horned Owls. Osprey raise one brood per year. Nests with 2-3 eggs are common for Osprey–in rare cases an Osprey will lay four eggs. The eggs will incubate for about 39 days before hatching. After the eggs hatch, the baby osprey are dependent on their parents for food until they gain strength and start learning to fly and hunt. The chicks will need to thrive because in late August or early September, they’ll migrate alone to Central and South America. 

While we have no way of knowing if this season will end with a successful brood for this pair, we look forward to watching their story unfold.
