Thanks to forum member golden1 for researching much of the information for this nest.

There is also a public Facebook group that follows this nest - http://www.facebook.com/groups/445733962172528/

Thank you to Xcel Energy and Raptor Resource Project for all you do for this nest. Fort St. Vrain is near Platteville, Colorado, on private property near the Xcel generation station; it's in the mountain time zone. The nest is in a large cottonwood tree near the junction of the St. Vrain and Platte rivers. It measures eight feet, one inch by six feet, seven inches by nine feet, ten inches and "has excellent flyways – perhaps due in part to stick-snapping and nest-building activities." The cameras got an update in August 2017 - the existing side-view cam was cleaned and repositioned, and a new PTZ cam was added, providing a great look down into the nest. The Raptor Resource Project reported that they "did the best we could to position all of the cameras out of poop range!" (Read more here, with thanks to the Raptor Resource Project.)

Mom and Dad Fort St. Vrain do not really migrate but they move around the area during the summer, but also visit the nest area. They usually begin nestorations in early October. Eggs are laid in mid February. Eaglets hatch in March and the eaglets have fledged in early June. Both eagles have been banded. Mom has 2 bands and Dad has one. He may have a orange-ish yellow, maybe faded tag on his right leg. With the new cam we may be able to get a better look at the bands. The top view we have been seeing the last few years has not afforded us a very good view of the bands. Mom has a deep inverted v on the front neckline. Dad's is more of a rectangle in shape but also can appear to be even along the front of the neckline.

Nest History

The camera was installed in 2003 and we started watching it in 2006. This pair successfully raised 3 chicks in 2006, 2 in 2007, 3 in 2008, and 2 in most of the previous years that they've been watched. The nest failed quite tragically in 2009, when their three eggs hatched in late March, but all three chicks died April 17; apparently one of the parents was lost or incapacitated around April 14, and the remaining parent wasn't able to keep the eaglets warm and fed during a bad wind/rain/snow storm; a second adult was seen shortly thereafter, leading to speculation that one of the adults might have eaten a poisoned prairie dog and been unable to function for a few days.

It appeared that there was a new female in 2010, possibly a relatively young adult as it looked as if there were a few brown feathers remaining in her head; the male appeared to be the same as last year, though it is hard to tell. Both eagles are banded, but the cam resolution isn't great enough to see numbers on the bands. The pair laid two eggs in 2010, and both chicks fledged successfully. They laid three eggs in 2011, two of which hatched, and both eaglets fledged successfully. 2012 was a very sad year at this nest - they laid three eggs, and all hatched - but one chick got stuck near the edge of the nest when it was 6 days old and died from exposure; the male did arrive during the night to brood the chick while the female brooded the other two at the center of the nest, but it was probably already too late. The remaining chicks died when they were a little over 2 weeks old when the adults were unable to keep them warm and dry during a severe wind/rain storm.

Well, things were slightly better in 2013 - the adults again laid three eggs, and they all hatched. Sadly two of the chicks were lost in mid-April as a result of a large snowstorm, which deposited over a foot of snow on the nest when the chicks were only about two weeks old. The remaining eaglet was renamed "Survivor" by those watching the cam, and fledged successfully. There was historic flooding in the nest area in the fall of 2013, with the St. Vrain Creek covering the camera equipment and solar panels with 5 to 7 feet of water, but happily those involved were able to get the camera streaming again. The weather was still an issue in 2014, but not as severe as the previous year; the pair laid three eggs, all of which hatched; the middle chick ("Argos") died when he/she was a little over a month old, after a week or so of wheezing and difficulty breathing; the other chicks ("Amara" and "Ajax") fledged successfully, though the younger Ajax was observed wheezing occasionally.

2015 was another challenging year here. The pair laid three eggs, and all three hatched, but the youngest D30 died at four days old after ending up outside the nest bowl, perhaps injured or maybe just stuck as the temperature fell, and then there was a bad storm when the remaining chicks were about 3 weeks old, and they didn't both fit under Mom and the one who was more exposed didn't make it (we think the younger, but can't be sure); the remaining chick (nicknamed "Aspen") fledged successfully. There was more sad news in 2016 - the pair laid three eggs and all hatched, but the nest area had a bad storm with cold heavy rain the night of April 15-16, and though both adults tried to shelter the 16 and 19 day old chicks, they could not keep them dry, and all three died. 2017 was better - they again laid three eggs, two of them hatched - and those chicks fledged successfully!

On February 16, the Raptor Resource Project reported in their Nest News:

The Xcel Energy Fort St. Vrain nest has (so far) benefited from an unusually warm winter. While light is by far the most important factor in many areas of a bird’s life (the onset of breeding season, migration, and molt are all influenced by daylight length), the lack of snowpack and ice means more food with less energy expenditure lost to simply staying warm. This won’t push eggs up by long periods of time, but can move egg-timing a little sooner or a little later based on our records. We’re all hoping the weather continues to benefit our sturdy prairie pair!

A nice look at the eggs, cozy in the nest cup.

Dad (I think) is up to adjust some nest material; I included both cams to show their different perspectives.

Two babies so far. Not sure if this is a first feeding. Looks like one of them has probably just hatched recently because it is having a hard time keeping it's head up. Couldn't get a good view of the 3rd egg to see if it is working it's way out. I'll check later if I have time... Dang work gets in the middle of my eagle watching.

Nice feeding for all 3 @9:40ish ET. FSV38 got plenty along with the others. Mom was giving some big bites but they all got them down. Sorry for the pixilated pics but that is just how this cam is here.

The babies are doing great so far. Right now they are scattered across the nest and a parent is feeding one of them, I think its the little one getting a solo feeding!

1:33 ETA They have now moved closer together and I see it was the middle one who had the lone feeding.

3:26 I am glad to see them getting a good meal because the snow is starting to fall and babies are already chittering with cold. Be safe babies. You just need to make it through the next 24 hours and warmer weather will be back. :luck:

I am so happy to see that all 3 babies are still doing well after the cold snap the last 2 days. Hopefully the worst is behind them and if another one comes they will be old enough to self-regulate their body temperature. The next week is looking good. :clap:

11:02 They are all being fed at the moment!

9:25 Mom just brought a good sized fish and 2 of the babies ate. One didn't come to the table. After feeding the 2 she flew up to a branch and then a few minutes later came down to the nest and is warming up the eaglet that didn't eat. :rh:

9:36 They are all snuggled in now as much as they can with how big they are getting!

Oh my goodness. These Eaglets seem to have popped their feathers overnight. When I looked in last night eaglet #3 was mostly grey fuzz. :w00t:

2018 Summary

We finally had a wonderful year at this nest - three eggs laid, three chicks hatched, and three eaglets fledged successfully!

With thanks to the Raptor Resource Project Forum and the Fort St. Vrain Eagle Cam group on Facebook, we know that the eaglets were wingersizing on June 14 and all fledged by June 22, and we know that a local observer reported seeing all three fledglings in the area a month later, on July 19, and one was still coming to the nest on August 1st.

This is a nest I've been following for a long time, and they've had more than their fair share of losses - so knowing all three fledged and were doing well makes my day. :D
