Three panels depicting hawking in England from various time periods, as reprinted in Joseph Strutt's 1801 book, The sports and pastimes of the people of England from the earliest period.The middle panel is from a Saxon manuscript dated to the late 10th century – early 11th century, as of 1801 held in the "Cotton Library", showing a Saxon nobleman and his falconer.It can be seen that the relevance of the "Boke" to practical falconry past or present is extremely tenuous, and veteran British falconer Phillip Glasier dismissed it as "merely a formalised and rather fanciful listing of birds".

In determining whether a species can or should be used for falconry, the species' behavior in a captive environment, its responsiveness to training, and its typical prey and hunting habits are considered.
To some degree, a species' reputation will determine whether it's used, although this factor is somewhat harder to objectively gauge.
In art and in other aspects of culture such as literature, falconry remained a status symbol long after it was no longer popularly practiced.
