A bird in the bush is worth $223,851 in the hand

(University of New South Wales) The arrival of a single Black-backed Oriole bird in rural Pennsylvania - 5000 kilometres from its usual home in Mexico - was worth an estimated $US 223,851 to the economy from bird watchers flocking to see it. The study, by a UNSW Sydney-led team, is the first to quantify the economic impact of a vagrant bird - a species observed outside its normal geographic range.
