Behavior

  • They are known to be aggressive birds, actively chasing away any intruders near their nesting site.
  • They are solitary outside of the breeding season.
  • They are playful, often seen tossing dried cow dung from their claws and then going after the falling object to catch it in mid-air.
  • They keep themselves clean by  bathing in dust or even stagnant water if available.
  • They are diurnal, returning to their abodes around 30 minutes before sunset.
  • Their main hunting style is to fly at high speeds at low levels until it can spot its prey, before accelerating in flight during the final charge.

Mating and Reproduction

Prairie falcons are monogamous for a breeding season, which lasts from February until July being at its peak during April and May. They breed once a year, after which a nest or rather a scrape is created for the eggs. 2-6 eggs are laid at intervals of 2 days. Incubation lasts for about 30-31 days.

Life-cycle

Although the female primarily incubates the egg, the males also lend a helping hand in this regard. The chicks are cared for around 40-41 days, after which they fledge and subsequently become independent after around 65 days of age.

Prairie falcons reach reproductive age at 2 years.

Calls and Communication

Prairie falcons make a sound that can be best described as ‘kree-kree-kree’.

In general, three types of vocalizations have been observed, an ‘eechup’ call accompanies a courtship, cackling calls denote territorial and alarm calls and loud ‘chitterings’ are used during aggressive encounters.

Adaptations

  • A special structure of the prairie falcon’s tail feathers lends it the ability to soar for up to 5 times longer distances by fanning out the tail and flattening the wings .
  •  The plumage of the prairie falcon helps it blend in with the rocky cliffs and ledges that it nests in, thus giving it a nice camouflage from potential trouble.
