What characterizes the Northern Cardinal's diet during Fall and Winter seasons?
Answer
A heavy focus on high-calorie seeds and fruits for energy reserves.
As temperatures decrease and insect activity virtually ceases, the cardinal demonstrates dietary plasticity by shifting its focus towards plant matter that is easily stored and rich in high calories and fats. Seeds, such as black oil sunflower seeds, become the staple food throughout the non-breeding season, providing the necessary insulation and substantial energy reserves required to successfully survive cold nights.
