Go birdwatching on a bus to see waterbirds if you want to catch a glimpse before they fly away.

Article title:
Buses, Cars, Bicycles and Walkers: The Influence of the Type of Human Transport on the Flight Responses of Waterbirds

A total of 730 experiments monitored 39 species of waterbird, using five stimulus types (single walker, three walkers, bicycle, car and bus) that were selected to match different management options available to those organising viewing at Birdwatching resources.
By monitoring the flight-initiation distances (FID) the results indicated that vehicular approach gave the shortest FID. The distance at which the bird walked, swam, dived, or flew away in response to the approach was recorded as the FID. The mean FIDs for each stimulus type, across those 39 species, were: walker, 67.6±37.5 m; three walkers, 92.3±67.7 m; bicycle, 67.7±37.1 m; car, 59.5±37.7 m; and bus, 81.2±96.5 m.

Estimated marginal means for the Flight-Initiation Distance of four species (black swan, Australian shelduck, chestnut teal and little pied cormorant) in response to five stimulus types.
Figures are derived from a General Linear Model which revealed a significant interaction between species and stimulus type. Values are estimated marginal means ± 95% C.I.
