Background: The flight initiation distance (FID) measures the a bird flees from an approaching predator. Factors such as frequency of predator approaches, direction gaze, variations in presence across different areas, and specific behaviors displayed by predators can all affect FID. For birds, people assume role predators. Methods: This study aimed to evaluate whether FID species Sicalis flaveola (Saffron finch, Aves, Passeriformes) is influenced number their gaze direction, comparing areas with greater lesser flow relating types behavior exhibited birds. Results: results showed that walking towards escape behavior, more generating longer FIDs than fewer people. If approach was eyes fixed on were longer. When birds alert, Conclusion: Overall, findings imply exhibit nuanced reactions human presence, even frequent encounters, highlighting advanced capacity for assessing responding perceived risks.

Aquaculture systems, replete with equipment noise originating from aerators, pumps, feeders, and filtration are known to exert substantial influence on fish behavior growth. In this research, the focus was directed towards comprehending impacts of aerator swimming, feeding, growth progression largemouth bass. course a 50-day experimental period, bass population segmented into two groups: (90.3dB re μPa RMS -1 ) ambient (70.4dB ). The findings indicated discernible disparities in swimming feeding between groups. Specifically, group maintained greater average angular distance physical separation their nearest counterparts than group, which were 43.61 ± 1.89° 85.47 1.72mm for 48.32 0.49° 97.01 0.57mm group. Furthermore, kinetic energy markedly lower as compared For first time, Shannon-Wiener diversity index leveraged gauge behavior, results signifying 2.69 0.07 higher that 2.51 0.02. Lastly, demonstrated compromised performance, significantly weight opposed along marked variations specific rate. These offer telling revelation about profound behavioral bass, thereby forming valuable referential base future research centered effects pollution aquatic organisms.
