As human populations continue to expand into wild habitat, associated human activities are of growing concern for wildlife survival. We placed tiny (0.5g) transmitters on small breeding migratory birds to continuously and instantaneously monitor heart rate and associated energy expenditure in response to experimental human disturbances.

We show no negative physiological response to any of the simulated disturbances whether it was a four-hour chase, repeated one-hour or nighttime disturbances performed by our team.

Our findings suggest that small birds are capable of quickly assessing and adapting to intermittent disturbances in their environment.
