Question: How old was Scotty Moore when Richards partnered with him for All the King's Men? Passage 1:The San Francisco Estuary is a major stop on the Pacific flyway for migrating waterfowl. Yet little is known about the flow of carbon in or out of the estuary via birds. Millions of waterfowl annually use the bay shallows as a refuge. Most of the birds are dabbling ducks that feed on submerged aquatic vegetation. Diving ducks (such as scaups) feed on epibenthic organisms like C. amurensis, representing a possible flow of carbon from that otherwise dead end. Two endangered species of birds are found here: the California least tern and the California clapper rail. Exposed bay muds provide important feeding areas for shorebirds, but underlying layers of bay mud pose geological hazards for structures near many parts of the bay perimeter. Piscivorous birds such as cormorants and pelicans also inhabit the estuary, but their trophic impact remains poorly studied.
 Passage 2:In the 1990s and 2000s Richards continued to contribute to a wide range of musical projects as a guest artist. A few of the notable sessions he has done include guitar and vocals on Johnnie Johnson's 1991 release Johnnie B. Bad, which he also co-produced; and lead vocals and guitar on "Oh Lord, Don't Let Them Drop That Atomic Bomb on Me" on the 1992 Charles Mingus tribute album Weird Nightmare. He duetted with country legend George Jones on "Say It's Not You" on the Bradley Barn Sessions (1994); a second duet from the same sessions, "Burn Your Playhouse Down", appeared on Jones' 2008 release Burn Your Playhouse Down – The Unreleased Duets. He partnered with Levon Helm on "Deuce and a Quarter" for Scotty Moore's album All the King's Men (1997). His guitar and lead vocals are featured on the Hank Williams tribute album Timeless (2001) and on veteran blues guitarist Hubert Sumlin's album About Them Shoes (2005). Richards also added guitar and vocals to Toots & the Maytals' recording of "Careless Ethiopians" for their 2004 album True Love, which won the Grammy Award for Best Reggae Album. Additionally, in December 2007 Richards released a download-only Christmas single via iTunes of "Run Rudolph Run"; and the B-side was a 2003 recorded version of the famous reggae song "Pressure Drop" featuring Toots Hibbert singing with Richards backed by original Maytals band members Jackie Jackson and Paul Douglas.
