Supplemental Information

Animation of monthly changes in Passerina ciris abundance index values with EVI analysis of remote sensing data

Figure 2 (.gif animation). Abundance index (AI) values for Passerina ciris specimens in Mexico by month, plotted against EVI analysis of remote sensing data. Red circles indicate the occurrence of P. ciris specimens, with the diameter of the circle proportional to value of Abundance Index. Green areas indicate high EVI values, correlated with regions with a high density of live green plants (photosynthetically active vegetation).

Data Deposition

The following information was supplied regarding data availability:

Data and code are available via two Github repositories: PABU (for statistical tests and raw data, https://github.com/elinck/PABU) and mexpabu (for GIS and EVI analyses and raw data; https://github.com/Eli-S-Bridge/mexpabu)

Funding

Support for fieldwork in northwestern Mexico came from the Burke Museum Endowment for Ornithology, and grants from Hugh S. Ferguson, the Nuttall Ornithological Club, and region 6 of the USFWS. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
