The birds have come back for what we hope will be the best season yet. Cameras are equipped with HD night vision for 24-hour viewing. Watch the peregrines hatch, raise and nurture their chicks and gently guide them into adulthood (as only somewhat violent birds of prey can do).
July 26, 2017 – Chase and Radisson are both still in the area and have been seen several times in their usual tuck-in spots at bed time. They haven't been spending too much time at the box, but there have been a few instances of them bonding at the box very early in the morning.
July 12, 2017 – GREAT NEWS! After a couple weeks of treatment, Chase and Radisson's chicks have made a full recovery. They are gaining weight and have been moved out to the hack site where they will be released in a few weeks. As for their parents, they've been spotted in the University area, but have not been spending any time in the box in recent days. Both Chase and Radisson were spotted last night, tucked in for the night in their usual spot, so it's likely that we haven't seen the last of them on the camera.
July 6, 2017 – After a week of treatment, all of the chicks appear to be healthy, which has resulted in some good weight gain. With all of the hot weather we've been having, they've also had a couple of baths. In other words, things are looking up! Chase and Radisson are still in the area and occasionally visit the nest box.
June 28, 2017 – Devastating news at this site. During the banding of these chicks yesterday afternoon, it was discovered that at least two of the chicks are not doing well and were consequently removed for treatment and testing. Testing confirmed that the two chicks are suffering a very contagious disease called Coccidia. If two chicks have it, then it is a certainty that the remaining two chicks have it. As a result, the last two chicks will be removed from the box today. All of the chicks will be treated and hand-fed over the next ten days, but this effectively ends the nesting season for Chase and Radisson this year. There is no possibility of putting a foster chick in for this pair of falcons as the box is contaminated and the foster chick would meet the same fate. The good news is that adult peregrines are not as susceptible to this disease.
June 21, 2017 – By this time next week, these four chicks will be sporting new bands and likely have some new adult feathers peeking through the fluff.
June 15, 2017 – As of today, the oldest chicks are 12 and 11 days old and the youngest is nine days old. There is always a bit of concern when there’s a two-day gap between hatches as the older and larger siblings tend to be in the front of the feeding line. It was a little touch-and-go for the first couple of days with the little guy getting very little nourishment, but then Chases came to the rescue. Once, while Radisson was feeding the older chicks, he fed the little one himself. Now the fourth chick is strong enough to fight his way to the front and get his fair share.
June 6, 2017 – Welcome to Number 4! Radisson and Chase’s youngest hatched around 7 a.m.
June 5, 2017 – Radisson and Chase are the proud parents of three chicks, all born between Saturday afternoon and Sunday night. Due to the cooler temperature we’ve had during brooding time, some eggs are taking just a little bit longer to hatch; watch for the fourth in a day or two. Radisson is a bit of a helicopter mama, not allowing Chase to do much besides bring them food. She takes care of feeding them and keeping them warm until they’re able to thermoregulate for themselves. Chase is allowed in for cuddles and egg-rolling when Radisson takes a little time for herself, but he’s always looking over his shoulder to see if she’s coming so he can make a quick exit.
May 30, 2017 – Watch for Radisson and Chase’s eggs to start hatching later this week.
May 17, 2017 – There’s not much going on right now. The peregrine couple are taking turns incubating the four eggs. Chase never seems to want to give up brooding duties when Radisson comes back from hunting.
May 3, 2017 – It happened! Radisson had her fourth egg, after a very quick labour, at 11:56 last night.
May 2, 2017 – Radisson and Chase have three eggs now. If another is forthcoming, it’ll likely happen sometime today.
April 25, 2017 – Chase and Radisson have their first egg. Be on the lookout for another later this week.
April 18, 2017 – It has been confirmed that the peregrines spotted here are Radisson and Chase, together since 2012. They have been doing a lot of bonding now that the work on the antenna has been completed. Radisson is often in the box, particularly in the early-morning hours, scraping away and generally getting things ready for egg-laying.
April 13, 2017 – At this point, we’re guessing at who’s who, but it looks like Radisson has been seen in the area. Chase followed along. There has been some work being done on the roof of this building but now that the work is done, we’re hoping Chase and Radisson will resume their courtship rituals.
Radisson and Chase raised a successful family here in 2015, but were unfortunately scared off in 2016, leaving the nest empty for the season.
Species at Risk
Although the peregrines get a lot of attention because they are obviously excessively cool, there are many other interesting species that are considered to be a Species at Risk, and there is no good reason not to learn about them! For example, the greater sage grouse is a very unique looking upland bird and there are very few left in Alberta. Also check out some of the bat conservation initiatives in Alberta.
