Starbucks (SBUX -1%) has  lost some market share to rivals in February, according to data from mobile specialist xAd.

The firm says Starbucks nailed down 11% of restaurant traffic market share during the month, down from 12% in January.

New initiatives from Dunkin’ Donuts, Panera Bread and McDonald’s could be a factor in the drop.

Starbucks has been leaning on higher average transaction prices to make off for decelerating traffic growth.
