Abstract

At the Massachusetts Institute of Technology (MIT), our finch colony includes more than 200 birds, with up to 45 breeding pairs maintained at a time. We also rear song-isolated clutches by separating offspring from the male parent at ~11 to 15 days posthatch (dph), while the female parent remains with the clutch; this prevents male chicks from learning their father’s song before downstream studies. Maintaining a zebra finch breeding colony using good practices is essential for bird health, welfare, and the reliability of scientific data. This article describes practices followed at MIT, which serve as guidelines for effective colony management using one male and one female per cage, including the introduction and resting of breeding pairs and managing offspring. (Note that aviary breeding, not considered here, is another option if detailed animal histories and controlled song learning are not a research goal.) The article covers dietary considerations, selection of breeders, breeding enclosures and accessories, breeding pair tracking, offspring development and management, resting and repairing breeders, and song isolation.
