A nest is the central record of this project. Each nest is a 3d printed box placed in a backyard or garden and paired with its own page on this website, where the observations made against it are gathered over time. Registering a nest makes one its monitor, responsible for placing it, watching it, and reporting on what it sees. The page allocated to a nest holds its location, the date it became active, the date of its most recent report, an image carosel, and a running count of the reports submitted against it.
Every nest contributes a small stream of presence and absence records to a much larger picture. Because the boxes are kept free of food and water and are spread across many separate gardens, the observations they produce are reasonably comparable and are not biased toward sites that have been baited. A long run of reports showing no birds is as valuable as a run showing occupancy, since both describe how the local population is faring and where suitable habitat may be recovering. Aggregated across every monitored nest this data builds a continuous record of small shrubland bird activity across southern California, which is difficult to obtain by other means given how fragmented the remaining habitat has become.
Dont be discouraged by quiet boxes. The test batch returned no birds for several months, and a long run of empty reports is itself a valid and useful outcome.
