摘要

You can imagine a researcher muttering this phrase while peering through a spotting scope and trying to find a rare Spoon-billed Sandpiper Calidris pygmaea amid a large flock of nearly identical shorebirds. The distinctive spoon-shaped bill is often hidden from view, making the bird especially hard to find. Even after a glimpse of the iconic bill, the researcher must watch until both legs can be seen well enough to determine if the bird has a leg flag. This often takes a while, and yet time is limited, because the survey must be completed while the tide is high. As the tide falls, the birds will spread out onto mudflats that stretch 50 km out to sea. The researcher cannot follow. Surveys are restricted to the upper mudflats because if humans venture out too far, they are at risk of drowning! In this issue of Wader Study, Chang and colleagues explain why they conduct research like this; why they have banded together from across the globe to count Spoon-billed Sandpipers in Tiaozini, China. They report how field data, collected over two consecutive years, was combined with sophisticated statistical models to produce a reliable estimate of the number of Spoon-billed Sandpipers using this important coastal region1.
