A strange phenomenon has emerged near Amazon.com Inc delivery stations and Whole Foods stores in the Chicago suburbs: smartphones dangling from trees. Contract delivery drivers are putting them there to get a jump on rivals seeking orders, according to people familiar with the matter.

Someone places several devices in a tree located close to the station where deliveries originate. Drivers in on the plot then sync their own phones with the ones in the tree and wait nearby for an order pickup. The reason for the odd placement, according to experts and people with direct knowledge of Amazon’s operations, is to take advantage of the handsets’ proximity to the station, combined with software that constantly monitors Amazon’s dispatch network, to get a split-second jump on competing drivers.
