After migration, birds engage in several key activities.
Breeding and Nesting
They select nesting sites, court, and build nests. Females lay eggs, and both parents may incubate them for periods ranging from days to weeks.
Raising Young
Chicks may be helpless at birth and require parental feeding, warmth, and protection until they fledge.
Molting
After breeding, many birds molt, replacing old feathers with new ones in preparation for the next migration or changing conditions.
Preparing for the Next Journey
Birds store energy by eating high-energy foods such as fruits, berries, insects, and seeds before embarking on fall migration to warmer wintering grounds.
