Ken Cummings, 82, has been feeding the pigeons in his back yard for nearly 20 years. "I love all living things" he says. "We've had all kinds of animals over the years, now it's just something that I keep doing." Ken and his wife Candy, 86, have lived in the same home in Tucson for 30 years, seeing the city grow up around them. Now with rising prices affecting cost of bird seed, Cummings has felt strain on something as simple as feeding his feathered friends. "Prices have doubled just in the last couple years" he says. "I don't think I'll stop though. If I don't feed 'em, what are they gonna eat?"
