Lay Summary A model of foraging flight speed can translate this easily observed behavior into estimates of difficult-to-measure habitat intake rate. The prey of Pacific dunlins is too small to be seen as they are ingested and are labor intensive to sample. But flight speed of small flocks foraging along the tide line varied systematically between 4 mudflats. Converting speed into flight power expenditure yielded net intake rates of 3.48–4.10W.Twitter: @CWEcology
