The Cardinal’s Nesting Rituals: How Love Builds a Home

Embracing the Season:
Cardinals begin nesting as early as March in warmer states. As spring sweeps in, pairs bond through melodic duets and gift exchanges (yes, males offer seeds to woo mates!). They often raise 2-4 broods annually until late summer.
Nest Locations:
- Hideaways: Dense shrubs, thorny bushes, or vines like honeysuckle. Height? Typically 1–15 feet high.
- Materials: Twigs, bark strips, leaves, grass stems, and rootlets woven into thick-walled cups.
- Unique twist? Males gather materials while females do 90% of construction, testing branch forks for sturdiness. (Source: Cornell Lab of Ornithology)

Hold your fingertip out – that’s roughly the size of a cardinal egg. These eggs blend seamlessly into their surroundings thanks to soft pale green, buff, or ivory bases. But what makes them stand out?
Signature Markings:
- Fine brown, lavender, or gray speckles concentrated near the wider tip.

Incubation & Hatching: The 13-Day Rush

Once the last egg drops, females dedicate 11–13 days to incubation. Males play supporting roles, feeding mates and standing guard.
Drama Unfolds:

Feeding Frenzy:
Both parents busily deliver insects and seeds. Pro tip: Attract these diligent families using high-energy foods from our proven cardinal feeding guide. Hatchlings take flight after 9–11 days – blink and you’ll miss it!
