Context paragraphs:
Seabird (novel): Seabird is a 1948 book for children and young people, written and illustrated by Holling Clancy Holling.  Ezra, the ship's boy on an 1850s whaling ship, uses his off duty time and walrus tusks traded from an Eskimo to carve an ivory gull, which later serves as the family mascot.  The book follows the history of the gull over the next 80 years as it passes from one of Ezra's descendants to another, while simultaneously tracing the history of commercial transportation, from Clipper ships to jet airplanes.

1989–90 Atlanta Hawks season: The 1989–90 NBA season was the Hawks' 41st season in the National Basketball Association, and 22nd season in Atlanta.  Injuries would hamper the Hawks again as Doc Rivers played just 48 games.  Despite the injuries, they went on a 7-game winning streak in December with a 13–6 record.  However, in January they lost six consecutive games falling below .500, and endangering their playoff chances.  Midway through the season, the team traded Antoine Carr to the Sacramento Kings for Kenny Smith.  The Hawks would close out the season on a strong note winning ten of their final 15 games finishing sixth in the Central Division with a 41–41 record.  However, they ended up one game short of the playoffs.  Dominique Wilkins led them in scoring with 26.7 points per game, and was selected for the 1990 NBA All-Star Game.  Following the season, Smith was traded to the Houston Rockets, and head coach Mike Fratello was fired.

Kenny Smith: Kenneth "Kenny" Smith (born March 8, 1965) is an American retired professional basketball player who played in the National Basketball Association (NBA).  He played in the NBA from 1987 to 1997 as a member of the Sacramento Kings, Atlanta Hawks, Houston Rockets, Detroit Pistons, Orlando Magic, and Denver Nuggets.
