In the fall of 1889 Tryon's husband was able to fulfill his long-cherished plan of studying at Harvard University and they moved to Cambridge, Massachusetts.

In 1891 she lectured upon the subject of New England's wild song-birds, her field being mostly in the scores of literary and educational clubs which abounded in Massachusetts.

She supplemented her lectures by illustrations in the shape of water-color drawings of each bird made by herself, showing its characteristic attitude and background.

[2][3] In 1997 her granddaughter Kate Schneider donated to the Richard Jefferies Society an unpublished typed manuscript based on Tryon's visits to Swindon.

It was published in 2010 as Adventures in the Vale of the White Horse "Jefferies Land": Featuring Kate Tryon's Original Paintings and Photographs from Her Visits to the Area.
