Hi everyone,
Sorry for the radio silence - I have been travelling and busy. At the start of the season, we cautioned you to buckle your seatbelts for the Hellgate Soap Opera! And our cautionary warning was warranted - there has certainly been a lot going on.
Finnegan did not return, and alas, we suspect that he might have died over the winter. :'( He could have gone somewhere else, but with such a successful breeding season last year, if he was still alive he would have most likely returned to the Hellgate nest.
Louis visited Iris and mated repeatedly with her, and she laid three eggs (April 29, May 1 and May 4). Iris' behavior is very interesting: without a dedicated mate, she has not been super attentive to her eggs. We suspect that from previous experience, she knows that without a partner bringing her food and helping to share incubation with her, the eggs won't survive. So she has been flying off leaving them unguarded.
The astounding thing to us is that the half life of an untended osprey egg is measured in seconds or minutes!! Almost as soon as Iris leaves an egg untended, a raven swoops in and flies off with the egg. This demonstrates the need for the eggs and small chicks to be tended 24/7, and without a bonded pair bringing up young is not possible.
But a few days ago, NEW GUY 2 showed up, and Iris seems to be pairing with him! He has been bringing in fish and driving off Louis. This is exactly what happened last year, and so Iris may lay some more eggs. Stay tuned . . . .
I have posted a timeline that summarizes events from the 2024 breeding season (on the bottom half), and the 2025 events so far.
More later!
Think pure thoughts, Erick Greene and the Montana Osprey Team
