Chronicles Katherine and Kenneth's bird-watching trips in great detail. The journal begins after the Ireys spotted their 700th bird species. Each entry is described as a "chase" after a specific bird or birds they are looking for and the diary has a total of 53 chases. The majority of the chases begin with a birding friend calling the Irey's to notify them of a bird siting. The couple will then quickly pack their car and travel to the site where the bird was last seen, sometimes driving well over a thousand miles in one direction. Many of the accounts detail travel expenses (gas, food, accommodation) as well as miles traveled.
