- Incubation Period: American Robins incubate their eggs for about 12 to 14 days. Eastern Bluebirds take a similar timeframe, while Blue Jays generally incubate for about 16 to 18 days.
- Hatching: Nestlings are altricial, meaning they hatch helpless and require care. Both parents often share feeding duties, ensuring rapid growth of the chicks.
- Fledging Age: American Robin chicks fledge around 14 to 16 days after hatching. Eastern Bluebird chicks leave the nest by approximately 20 days. Blue Jay fledglings typically depart the nest at about 17 to 21 days.
- Post-Fledging Care: Parent birds continue to feed fledglings for several days after they leave the nest. You might observe fledglings perched nearby, calling for food.
