Lots of sitting still going on! Did you know? Ferruginous hawks are known to sleep standing up, often balanced on one leg!

We are roughly halfway through the incubation period!
With an average incubation of 32 days, we should be seeing some adorable hawk chicks in a little over 2 weeks.

If you thought staying at home all the time was bad, at least your bed isn't covered in snow!

Although we can't see if there are any eggs yet, she does seem very interested in something at the bottom of the nest!

Both hawks seem to be working diligently on their nests. Did you know? In times past, ferruginous hawks would use bison bones, fur and dung in their nest building!

Did you know? Both the male and female work on the nest, but seem to have different roles. The male usually retrieves materials while the female arranges them.

The ferruginous hawks are back!
The good news is that the cameras are working great.
The bad news is... she is already onto us.

Ferruginous Hawk (Buteo regalis)
One of the biggest challenges for ferruginous hawks is the loss of suitable nesting habitat; from 1992 to 2005, the species declined by 64 per cent in Canada. The best thing we can do to bring the population back up is to provide nesting areas for them in suitable locations and then not disturb them.
Appearance
- An At Risk species in Alberta (around 865 pairs estimated in Alberta based on 2015 survey).
- Wingspan can reach 1.5 metres.
- Largest of North America’s hawks (63 cm long).
- Light-coloured, rusty back, light and unbanded tail (there is also a dark morph with rufous-brown feathers)
Habitat
- Migrate from southwest United States and Mexico.
- Prefer areas of uncultivated pastureland or prairie.
- Only one of two raptors to use grasslands as main habitat.
Food
- Mainly feeds on rodents (ground squirrels, mice, voles, white-tailed jackrabbits).
- One pair (with chicks) consumes an average of 480 ground squirrels per season.
- Hunt during the day when squirrels are active.
Timeline
- Arrive in Alberta in early to mid March.
- Nest and raise chicks from mid-April to late-July.
- Migrate south in September and October.
Courtship
- Mainly monogamous.
- Meet and perform dancing routine in the sky. Finally, the pair grasps beaks and talons and spirals downwards.
Breeding
- Birds return to the same area (often the same nest).
- New sticks and twigs are added to existing nest each year.
- Historically, they used bison bones and dung.
- Nests can be found from ground level to 20 metres high (cliffs, haystacks, farm buildings, trees).
- May have up to five nests but only use one each year.
- They lay three to five eggs each year.
Lifespan
- Incubation is 32-36 days.
- Attempt flight at about two months.
- Mature at three years of age.
- Live to 15 or 20 in the wild.
