 Both parents share the duty of feeding fledglings.Mean length of post-fledging parental care is 40 ± 5 days (n = 35 broods), but parental care can be very long (up to 88 days after fledging).Parental care gradually diminishes over time after fledging, and can be 1–2 weeks shorter when the pair subsequently starts a new nest in the same season.
