Behavior
- Cassin’s finches crouch and stay in that position whenever they feel threatened. Despite being in a statue-like position, they just move their throats to produce alarming call in a low tone.
- They usually reside at higher altitudes but come down to lower elevations during winter months.
- They extend their neck towards the front with their closed bills and keeping the body in
a horizontal alignment to frighten their enemies. - Whenever a female looks for a nesting place, her male counterpart wards off other male finches from the place.
- Post-breeding, the finches join other birds pine siskins, evening grosbeaks, red crossbills, and other finch species.
Mating & Reproduction
During the breeding season, they make a pair and mate. Following that, the female makes a nest with twigs, weed stems, and rootlets where she lays 3-6 bluish green, black and brown spotted eggs. She incubates them for 12-14 days. The male usually feed the female during the phase.
Life-cycle
After hatching, the juveniles are fed by both the parents. After two weeks, the young ones leave the nest. They attain sexual maturity at around 1 year of age.
Interesting Facts
- The male finches look similar to a female during his first year, so female finches often ruffle their beautiful plumage to indicate that she is not a male.
- Cassin’s finches are known for their salt craving and they often fly to mineral deposits for satisfying the quench.
