The nest-chick addition method is generally effective for many songbird species but requires caution when applying to raptors due to the need for expertise.

• A. True
• B. False
• C. Only for waterfowl
• D. Not advisable for any raptors

Answer: (A)

Nest-chick addition relies on nestlings being integrated into a host nest in a way that the parents recognize and feed them as their own. For many songbird species, this can work well when the age, size, and timing are matched and the addition is done carefully, because these birds often accept additional nestmates and share parental feeding duties if cues line up. Raptors, however, require specialized expertise because their growth rates, feeding patterns, and parental recognition cues differ significantly from songbirds, and missteps can lead to nest abandonment, injury, disease transmission, or imprinting problems. A trained rehabilitator understands these species-specific needs, can assess risks, and follows best practices to minimize harm when considering nest-chick addition for raptors. So this approach is generally effective for many songbirds but should be pursued with caution and the appropriate expertise when raptors are involved.
