Feeding Habits of the Purple Finch
Purple Finches feed mainly on seeds, buds, blossoms, nectar, tree fruits and occasionally insects. In winter, when they are mainly eating seeds, nuts and fruits, they use their beak and tongue to crush seeds and extract nuts. In the summer, when feeding on nectar, Purple Finches use their beak to crush the calyx at the flower’s base and extract the nectar with their tongue, leaving the upper flower parts undamaged.
Other random facts regarding the Purple Finch’s eating habits include following: Research shows that Purple Finches weighed in the early morning increased their body weight by 3.5 grams (13.5%) when re-weighed in the afternoon.

The mean handling time of a single sunflower seed is just over a minute and they prefer thin to fat sunflower seeds.
