What is the narrator point of view in the book, The Feather Thief?

The perspective changes throughout The Feather Thief, loosely according to the structural divisions of the book's three parts, though there are also occasional perspective shifts within a Part. The prologue is told primarily in third person limited omniscient from the perspective of Edwin Rist, though there is a also a brief section where the perspective shifts to that of the Tring security guard, also in third person limited omniscient. The second half of the prologue is written from the perspective of author Kirk Wallace Johnson and is told in first person limited omniscient. Part One is written entirely in third person, though the perspective changes to that of different individuals including Alfred Russel Wallace; George Mortimer Kelson, one of the Victorian fathers of salmon fly-tying; early conservationists; and a young Edwin Rist. Part Two is told from the alternating perspectives of Edwin, the museum staff, and police investigators, primarily Adele Hopkin. Part Three is a departure from the third person and returns to the first person limited omniscient perspective of author Kirk Wallace Johnson. The main narrative of Part Three is told entirely from this perspective, though the perspectives of other individuals like Edwin Rist and Long Nguyen are included through Johnson's interviews with them.
