Data and code from: Variable evidence of radio-tag backpacks affecting hummingbird time budgets in captivity

Background: With wildlife-tracking devices miniaturizing rapidly to enable ever-more research on ever-smaller taxa, there is a newfound urgency for affordable, field-accessible biologging ethics studies. We designed a 3-hour time-budget experiment to investigate how radio-transmitter backpacks affect hummingbirds’ behavior in Colombia.
Methods: Using a large flight arena, we individually filmed 25 Black-throated Mangoes (Anthracothorax nigricollis) under two randomized treatments, tagged and untagged, to characterize and quantitatively compare behavior. We created time-budget breakdowns of our behaviors of interest—flying, hover-feeding, preening, and perching—then fit a series of linear mixed-effects models to determine the effects of tagging and additional experimental and environmental variables on behavior. We also designed an aviary-style “Entanglement Experiment” (n = 30) to determine if any individuals would snag on vegetation while equipped with the backpack harness, and tested ..., As described above, we performed enclosure-style experiments (n = 25) consisting of two randomized treatments, tagged and untagged, to characterize and quantitatively compare behavior of Black-throated Mangoes when equipped (or not) with radio-transmitter backpack harnesses. Each treatment included a 30-minute acclimation period and a subsequent 60-minute observation period, in which we filmed the hummingbird's behavior. As such, we generated 50 one-hour videos throughout this study, which we analyzed using the Behavioral Observation Research Interactive Software (BORIS). With BORIS, we created time-budget breakdowns of our behaviors of interest: flying, hover-feeding, preening, and perching. 
In this dataset you can find our time budget breakdowns for each individual treatment for each bird. Also included are additional covariates that we considered relevant to hummingbird behavior: treatment type (2 levels: tagged and untagged); individual’s weight at the start of the trial (cont..., , # Data and code from: Variable evidence of radio-tag backpacks affecting hummingbird time budgets in captivity

## Description of the data and file structure

We experimentally compared the individual behavior of 25 Black-throated Mangoes when they were and were not wearing radio-transmitter backpack harnesses. Each treatment (tagged and untagged) was randomized in order and we filmed the birds for 60 minutes. We broke down the birds' behaviors (flying, hover-feeding, preening, and perching) using the Behavioral Observation Research Interactive Software (BORIS). We also ran aviary-style experiments with 6 separate individuals overnight to determine if there would be any negative device effects that only became apparent after a longer period of time.
