Local lists and colony surveys
Tucker began recording Somerset birds while still a student. His list for Chewton Mendip and district appeared from 1918, with subsequent additions.
The Rookeries of Somerset (1935) brought together extensive survey work and maps. Local reports connected observations with identifiable sites and checked records.

Handbooks and journal editing
Tucker contributed to The Handbook of British Birds and succeeded H. F. Witherby as editor of British Birds in 1944. These roles organized scattered observations into reference and journal literature.
He also worked on regional bird reports and helped observers scrutinize records. Reference writing, editing and local reporting were connected parts of his ornithology.

Organizations for cooperative observation
At the BTO’s formation in 1933 Tucker was secretary and Max Nicholson treasurer. These initial roles should be distinguished from subsequent appointments.
In 1938 Tucker joined Nicholson and Alexander in establishing the Edward Grey Institute, providing a more stable setting for cooperative surveys, information exchange and university research.
