True or False: The term "austringer" refers to someone who primarily flies eyases.

The term "austringer" specifically refers to a falconer who primarily works with eyases, which are young hawks or falcons that have yet to fledge or leave the nest. Traditionally, austringers focus on training these young birds, as they are considered more malleable and receptive to training compared to older, more experienced birds. This practice allows the austringer to instill specific behaviors and skills from an early age.

In contrast, the other options do not accurately capture the definition of an austringer. The idea that it is false overlooks the established meaning within falconry terminology. The notion that it can be sometimes true or depends on the bird introduces ambiguity that does not align with the more defined role of an austringer in the falconry community. Thus, affirming that the statement is true provides clarity in understanding the specific duties and focus of those involved in this area of falconry.
