I have not heard any news of Madame X since her release. I can only hope she is doing well somewhere.
Her mate, Polyo, did not return to the nest this year.
While Madame X was in care, a new female showed up at the nest. She is Tahoe, banded black/red 33/U, from the Eastlake nest in Ohio, born in 2012. Tahoe spent the winter at the Milwaukee University Biosci Building nest; it was obvious that she really wanted that nest.
When the long-time resident female returned from migration at the end of February (a little earlier than usual), she displaced Tahoe.
A new male also showed up at the Milwaukee County Power Plant nest. He is Lightning, banded black/red 84/R, born in 2012 at the Oak Creek Power Plant nest. He and Tahoe had three chicks.
When the chicks were still young, Lightning abandoned Tahoe and their chicks. He then showed up at the Milwaukee nest (the one Tahoe wanted). The resident female there and her long-time mate, Hoffman, banded black/green 54/M, had four chicks.
When their chicks were still young, Hoffman disappeared. Lightning moved in and helped the resident female raise her four chicks. He stayed, and he and the resident female are still there. The four chicks fledged successfully.
Sadly, Hoffman's body was found on a roof in late June. Hoffman, born in 2003 at the Edgewater Generating Station, was a great tiercel, an excellent provider and a wonderful father to all his chicks.
Back at the Milwaukee County Power Plant, Tahoe did a great job of raising her three chicks on her own, and all three fledged successfully. I did see one, and sometimes two, of the chicks coming back to visit the nest on occasion.
I have not seen an adult at the nest for a while; the last time I saw an adult I believe it was Tahoe, since I caught a glimpse of a black/red band. Although it was not mentioned anywhere, Madame X appeared to have been rebanded black/blue 01/H.
