The traditional term for a male falcon is tercel (British spelling) or tiercel (American spelling), from the Latin tertius because of the belief that only one in three eggs hatched a male bird. Some sources give the etymology as deriving from the fact that a male falcon is about one-third smaller than a female [ 18 ] [ 19 ] [ 20 ] ( Old French ...

In 1986, a lost captive-bred female prairie falcon (which had been cross-fostered by an adult peregrine in captivity) mated with a wild male peregrine in Utah. The prairie falcon was trapped and the eggs removed, incubated, and hatched, and the hybrid offspring were given to falconers. The wild peregrine paired with another peregrine the next year.
The male falcon is at least 10 years old, the female 11. This year, the female laid her first egg on March 20, the earliest ever for this nesting pair. The next came the morning of March 23, the ...

The majority of prey is 150g or less, a weight that even the smaller tiercel (male) can carry long distances back to the nest. [17] Most prey is thus 30% or less of the weight of the tiercel, which is a common prey size fraction across numerous species of falcons where the males do the majority of the hunting during the nesting season.
The peregrine falcon has a body length of 34 to 58 cm (13–23 in) and a wingspan from 74 to 120 cm (29–47 in). [11] [20] The male and female have similar markings and plumage but, as with many birds of prey, the peregrine falcon displays marked sexual dimorphism in size, with the female measuring up to 30% larger than the male.

Peale's falcon concentrates on hunting Alcids, often nesting very near seabird colonies for this purpose.However, this is not necessary for a successful eyrie.A study on Amchitka Island from 1968 to 1973 found that an average of 18.6 eyries on the island were in no close proximity to seabird colonies, as no sizeable colonies existed on the island.
