Wild bird rehabilitation involves complex welfare considerations around minimizing human imprinting, appropriate housing, and determining releasability versus humane euthanasia.
Wild bird rehabilitation involves making welfare decisions under genuine uncertainty about outcomes and with ethical obligations to both individual birds and wild populations. The welfare of individual birds must be assessed against the welfare of animals held long-term in captivity that cannot be released. Honest assessment of releasability - and willingness to recommend euthanasia when long-term captivity would not serve welfare - is the mark of a welfare-focused rehabilitation program rather than a commitment to treatment at all costs.
