According to the site below, which compiles serious sources, the maximum recorded lifespan is 14.6 years for the American crow (Corvus brachyrhynchos), and 24.7 years for the raven (Corvus corax).
There are other interesting records for family Corvidae, including 36 years for a captive Azure jay (Cyanocorax caeruleus); these are from South America and actually occur here in Argentina, where I live :-)

However, another interesting and usually authoritative site, the Animal Diversity Web, mentions more than 44 years for a captive Corvus corax individual. It also mentions that the lifespan of wild animals are usually much shorter (+/- 14 years).

The record seems to be 14 years and 7 months, according to this site:
http://www.wildbirds.com/protect_livelong.htm

However, this page indicates that the average is 15 months (that's probably including all of the baby birds that are eaten early on in the wild by predators) and that the maximum known is 9 years:

While this third site says that they can live to be 10 years old, plus or minus two to three years: http://www.zeebyrd.com/corvi29/

Crows stay approximately 2 a protracted time. + or - 5 years. I actual have even heard as much as 30 years, yet that had to have been nicely fed and enable loose alot of its existence. they are in a position to be domesticated, sparkling birds to boot. Care and success to you.

in the wild...anywhere from 7-15 years. One site claimed in captivity they can live up to 30 years.
