|You can see an egg as the bird changes positions while incubating.|
This nest pole was erected in 2001 in response to ospreys attempting to build a nest on an electric line.
Both osprey worked together to create the nest, with the male bringing in up to 4’ long branches, and the female inter-weaving with other sticks in the nest. Once eggs are laid (typically 1-3), the osprey take turns incubating the eggs. When the chicks are 10 days old, they are already mobile and eat 1-3 lbs. of food per day.
You might also be interested in the history of work done on some osprey migration tracking. Mark Martell, formerly of TRC and who now works for Audubon Minnesota, put transmitters on birds in the US, and tracked their annual migrations from breeding grounds to wintering grounds in Central and South America.
Some truly overachieving birds even make it to Argentina!
