Daily pageviews in English-language Wikipedia for nine bird species.

Pageviews for three migratory birds (top panel) show a strong seasonal peak coinciding with the bird’s arrival on breeding grounds in the United States. Pageviews for three North American resident birds show more variable patterns (second panel), and pageviews for three tropical species (bottom panel) that do not occur in the US show fluctuations over the course of the year but no consistent seasonality. Investigating the drivers of these patterns for individual species could be a rich area for further study, in particular as to whether changes in pageviews can be related to trends in population abundance and location or to particular human activities. Background gray shading indicates the dates of spring in the Northern Hemisphere. Pageviews for each species are scaled by subtracting the mean and dividing by the standard deviation (for data used in plots, see S1 Data).
