Bohemian waxwings breed in Alaska and northwest Canada, but are known for their tendency to move south in the winter when their winter diet of fruit becomes scarce. These irruptions can occur in huge numbers – thousands of birds, in some cases. Their name reflects their nomadic tendency (much like gypsies, or bohemians) and their unpredictable migration patterns. Mountain ash, juniper, cedar and holly berries are among their favorite foods, and typically they will stay in an area with an abundant food source until that food is stripped before moving on. Like their relatives, cedar waxwings, with whom they often flock, they are susceptible to alcohol intoxication, and even death, from eating fermented fruit. Someone I know who was unaware of this phenomenon was alarmed when she observed a number of waxwings lying on the ground outside her house, looking for all the world as if they were dead. To her great relief (and disbelief), an hour or two later the ground was bare, the inebriated birds having sobered up and departed.
