Graph: Number of Laysan Albatross Nests and Chicks at Kilauea Point

Using the data at the bottom of the page, complete the bar graph below, which shows the number of nests and chicks that fledged (flew off after nesting) each year.  There are two "bars" for each year, one for nests and one for chicks.  Not all eggs hatch, so the nest bar will usually be higher than the chick bar.  How many albatrosses do you think will fledge in 1999?  Why?
