Justification of Red List category
Buff-breasted Sandpiper is suspected to have undergone a moderately rapid to rapid decline which is thought to be driven by habitat loss in non-breeding and/or migratory stopover sites, but changes in breeding habitat due to climate change may also be affecting populations. Rapid to very rapid reductions have been detected from a large network of migration sites in North America, which may reflect a significant reduction in reproductive success. But a decline has also been recorded across large-scale sampling surveys of the breeding range in Alaska. The precision of rate estimates may be poor due to the species’ low side fidelity and annual variation in stopover sites, but there appears reasonable evidence to support that a concerning decline is underway. Greater survey effort has resulted in the population size being revised upwards considerably, hence the species is not believed to be at risk due a small population size at present. Due to the likely rate of population reduction, Buff-breasted Sandpiper is assessed as Vulnerable.
