Final answer:
Radio telemetry is the most suitable method for estimating the lifetime dispersal distance of the European Starling, as it allows tracking over long distances and periods.
Step-by-step explanation:
The most appropriate method to estimate the lifetime dispersal distance of the European Starling would be radio telemetry. This technique involves attaching a small radio transmitter to the animal, which can then be tracked over a wide range and for extended periods. This allows researchers to gather detailed information on the movements and dispersal patterns of the starlings.
Other methods like mark and recapture are useful for determining population size and density, whereas techniques such as quadrat sampling and pitfall trapping may not effectively measure long-distance movement and behavioral observation may be limited to visibility and shorter time frames.
