New reports in from the nests
Pictures here: Pleasant Prairie Power Plant
Adult male PBR (b/r) 07/B, who has nested here since 2012, has likely been present all winter again. His bands were read Jan. 26. Also identified was adult female Olivia (b/r) 00/Y on that same date, and both have been observed regularly since then. Olivia nests at the Kenosha Hospital but spends parts of her winters at the PPPP site. She usually leaves and returns to the hospital site as soon as the resident female Thilmany (b/g) 44/N returns and chases her off. Last year, Thilmany returned on March 8, but there has been no sign of her yet, so it is not known if she survived the winter. Not known which falcon may end up nesting at PPPP this year. The first egg was laid at this site last year was on April 4.
Oak Creek Power Plant
Adult male Scott (b/g) M/Y was first observed Feb. 2 and seems to come and go. If he nests here this year, this will be Scott’s tenth year at OCPP. He'll also be 15 this year, making him the oldest known nesting male in Wisconsin. No female has been seen at this site yet, so it is unknown whether or not female Eclipse (b/r) 67/H, who nested at OCPP from 2011-2014, is still alive or whether she will be returning from wherever it is she may have overwintered. On March 4, a juvenile female peregrine, Rosalee (b/r) C/94, produced in 2014 at the MG&E nest site in Madison, was identified. Last year, the first egg here was laid on April 2.
Valley Power Plant
An unbanded adult female peregrine was seen on Jan. 26, and she has been present on and off ever since. An unbanded adult female also has been seen at the nearby Veolia Water Milwaukee site and may be the same falcon seen at VAPP because the two sites are close to each other. An adult male that appears to have a b/r band also has been seen but not yet identified. The male here last year was Hercules (b/r) 60/H, and he might be back. This site failed last year as there was a turnover of adult females just before the eggs were due to hatch.
Milwaukee County Power Plant
Adult female (b/r) 33/U, who nested at MCPP last year, was identified Jan. 31. She also has been regularly observed at the UW-Milwaukee nest site throughout the winter, so she has been traveling between these two sites. On Feb. 8, Suzuki (b/g) E/06 was identified. Interestingly, Suzuki was identified at the MG&E nest site in Madison in 2010 and was missing his federal band (see image). Suzuki did not nest at MG&E that year.
Between 2009-2011, the adult male at the Jefferson nest site (about 30 miles E/SE from the MG&E site) could not be identified. However, the adult male was banded b/g and clearly was missing a federal band in 2011. The Jefferson nest site failed (raccoon predation) in 2012 and 2013, and no band information was obtained. In 2014, one young produced at the Jefferson site was lost, and the adult male was not identified.
Although there is no way of knowing for sure, the adult male at the Jefferson site between 2009 - 2014 may have been Suzuki. If a site fails, the adult(s) sometimes moves on in search of greener pastures. Though uncertain, Suzuki may be trying a new site this year after three consecutive lost nests at Jefferson. Whatever the case, Suzuki has been present at MCPP regularly and bringing in prey for (b/r) 33/U, so it’s beginning to look like this pair may nest this year. The first egg was laid at this site last year on April 9.
Port Washington Generation Station
This year, things have been very slow. So far, only one peregrine was seen perched in front of the new nest box. Wildcat, a male produced at Valley Power Plant in 2013, was identified Feb. 9. Last year, Ives (b/g) 78/N nested at the site and has nested at PWGS since 2007. Ives was first identified last year on March 20, so its anyone’s guess as to how things will proceed here this season as far as males go. The other unknown is whether or not female Brinn (b/r) 84/X, who nested here last year, will return. If she migrated this winter, she may be on her way back north, and if this is the case, she may be seen soon. The first egg was laid here on April 11 last year.
Presque Isle Power Plant, Marquette, Michigan
No peregrines have been seen so far this year. Last year, a male was first observed on Feb. 22, and an adult pair was present on March 6. If the unbanded adult male that nested here in previous years is gone, it may take some time for a new male to claim this territory. And if (b/g) P/Z, the female that has nested here since 2011 returns, she may have to attract a new male, which means that if a successful nest is made here this year, it will likely occur later in the nesting season. The first egg was laid here on April 14 last year.

Not sure if they are ours or just passing by
Hi Kittenface! Things are starting to stir at the WE nests- and I hope it's all good. I saw your note yesterday and thought of Tahoe. I didn't see anyone on Biosci's cam yesterday or the day before. I really hope she has gone back to Mil. County. Whoever is operating the cams pulled in very tight at the 9:00 pic at that cam. Oak Creek was at her nest for 3 poses, and Valley for one catch. Happy falcon watching!
I looked at the cams until 12 noon. Nice close up of (hopefully) Tahoe at 11, and (hopefully) Eclipse at Oakcreek at noon...... A cool picture of Thilmany choking down on prey at 4:00.
Thank you for putting together those catches, Kittenface! So good to have them show up more frequently!
Yes, Thankyou, Kittenface! And here I thought that was Thilmany at Pleasant Prairie all this time! Sounds like these Falcons are playing musical nest boxes again this year... And I'm really glad Tahoe may have a faithful mate this year!
