Since Bald Eagles live in many different places, it could be inferred that each region of Bald Eagles has its own distinct dialect (Eakle et al., 1989). To test this theory, scientists could observe Bald Eagle populations in different areas of the world. They could make sonograms of the songs in the different areas then they could take those sonograms and compare them to determine if the sonograms vary by region that the bird lives.<\/p>\n Song Learning:<\/p>\n After hatching, the vocalizations produced by the Bald Eagle is a single toned peep, with little change in frequency. Cheeping is used early in life to communicate with adults if the bird is frightened or feels in danger (Buehler, 2000). By day 30, the call has many characteristics of an adult, and is fully developed at four weeks post-fledgling (Gilbert et al., 1981). Experiments done on Bald Eagles suggest that birds raised in acoustic isolation produce atypical songs in their adult stages (Eakle et al., 1989). This leads many scientists to believe that the song of the Bald Eagle is learned early in life, during a particularly sensitive period in their development. This song learning is similar to most species that are passerines. Sonograms recorded of the Bald Eagle show variance year to year, which also suggests song learning from the parents (Buehler, 2000).<\/p>\n Citations:<\/p>\n Buehler, David A. 2000.
