That's a good question. A quick scan of the literature suggests that in some birds the answer is no. I believe this is thought to be due to the evolutionary constraints of flying. "Some seabird species exhibit extremely slow age-related declines in both survival and reproductive output, and even increase reproductive success as they get older. Slow avian senescence is thought to be coupled evolutionarily with delayed maturity and low annual fecundity. " [1] "Long-term population studies of wild seabirds (e.g. terns, gulls and albatrosses) suggest that these species show little or no decline in reproductive output, even when increasing mortality rates suggest the occurrence of senescence in other systems."
