Figure 2.6. Spectrographic representations of calls from five different baleen whale species. The
time and frequency scales are the same for the blue and fin whale examples but different from that
for the humpback, right, and bowhead whales. Blue and fin whale samples recorded off San Nicolas
Island in 1997 and Loreto, Mexico, in 1999, respectively; humpback whales recorded off Hawaii in
1995; right whales recorded in Gulfo San Jose, Argentina, in 1977; bowhead whales recorded off
Point Barrow, Alaska, in 1988. All recordings made using recording systems with flat frequency
response in the 10–5,000-Hz band.
