The Erasian Tree Sparrow (Passer montanus) feeds above the ground which can increase the risk of threats by domestic cats and humans. High vigilance is needed to avoid threats and is shown through its blinking behavior. When blinking, limited visual information is received. This study aims to determine the sparrow's blinking strategy which consists of blink rate, blink duration, percentage of blinking time and blinking proportion during feeding in the presence of humans and domestic cats. Seven adult sparrows were given three stimulus treatments in the form of a human face, a cat face and branch (as control). Three observation periods were conducted before, during and after the stimulus for one minute each. Food was provided throughout the observation. Blinking behavior was observed through the frame-by-frame sequence by video. The results showed when humans and cats were present, the blink rate, blink duration and percentage of blinking time were lower than branch (p<0.05). During feeding, however, the presence of human and cat faces showed a higher blinking proportion with monitoring, with both of blinking durations being faster than branch (p<0.05). These results suggest that the sparrow's blinking strategy while feeding activity in the presence of humans and domestic cats is to reduce the blink rate, blink duration and percentage of blinking time, and the blinking proportion while feeding.
