Database on ingestion of grit and arthropods by hummingbirds

This database contains data on the amount of grit particles and arthropods ingested by six hummingbird species sampled in a seasonal ecosystem in western Mexico. Data were collected from the stomach content analysis of the sampled hummingbirds over a one-year period. Data presented are: 1) the total number of grit particles per stomach, 2) the biomass of arthropods ingested (g dry weight/stomach), 3) the Orders of arthropods ingested, and 4) the average chitin content of arthropods ingested (percentage dry weight).
