 Most accipitrids feed their nestlings by feeding them strips of meat or whole prey items, but most vultures feed their nestlings via regurgitation.Fledgling often takes considerable effort for young birds and may take several weeks as opposed to days in many other types of birds.Once independent of their parents, young accipitrids often most wander for considerable stretches of time, ranging from 1 to 5 years before they attain maturity.
