From: Habitat-dependent changes in vigilance behaviour of Red-crowned Crane influenced by wildlife tourism
Frequency of vigilance and percentage of time spent on vigilance behaviour by individual red-crowned cranes at different distance intervals from wildlife tourists. Circule with blue denotes significant difference between two adjoining gradient of distance (post-hoc Student-Neuman-Keuls (S-N-K) test, P < 0.05). Block diagram with gray denotes samples below the average level of vigilance (vigilance frequency: 1.47/min; time spent vigilant: 19.98%). Value was showed as Mean ± SE.
