His book This Bondage: A Study Of The "Migration" Of Birds, Insects, And Aircraft received positive reviews in two science journals. For example the British Medical Journal described it as a "charming work that will be welcomed by all his fellow bird lovers for the very clear exposition which it contains of the principles of bird flight." A more critical review in The Auk criticized the book for trying to discredit the evidence for evolution and noted that:
He fails to take the physical fact of inertia sufficiently into consideration, nor does he grant to most birds the superiority over normal meteorological conditions which they undoubtedly have. He builds up an elaborate theory in which zoological dispersal, migration, and other natural phenomena are dependent ultimately upon temperature plus the winds. While his deductions and reasoning are not without considerable value, they are undoubtedly of most value to one capable of realizing the weakness of Commander Acworth's ornithological information... In developing his own special theories he sets up one straw man after another and succeeds to his satisfaction in knocking it down.
A review of his Bird and Butterfly Mysteries in the journal Bird-Banding was also negative:
The kindest possible appraisal of Captain Acworth's theories of migration is that they might be true if birds acted in the way he thinks they do and if they flew in an atmosphere in which there was no turbulence and in which the only winds were the prevailing winds of the climatic charts. But his theories do not hold in the imperfect real world in which ornithologists must work.
Acworth received criticism from naturalists for not being a field observer, something which he confessed to. His arm-chair speculations such as his unorthodox ideas about cuckoos were disproven by observational research.
