Observations were made on four nesting attempts by Long billed Curlews (Numenius americanus) in 1965 and 1966 in Box Elder and Cache Counties, Utah. The location, nest composition, and number of eggs of each nest are presented. In one instance eggs were laid at intervals of forty eight hours or less. Data on weight and measurement and color of eggs are given. Data for the only two completed nests indicates incubation periods of twenty-seven and twenty-eight days respectively. The distraction display of the incubating family is described for the first time.
