The lesser redpoll is a small finch of birch and alder scrub whose UK population has fallen sharply, raising significant welfare and conservation concerns.
Lesser redpolls face chronic food stress when birch and alder scrub is cleared for development or managed out of landscapes. Nestlings require caterpillars as well as seeds, making them sensitive to invertebrate declines caused by pesticides. Welfare deteriorates when nomadic flocks cannot locate adequate seed patches during harsh winters.
