In an intriguing study published in the journal Frontiers in Ethology, zoologist Vladimir Dinets from the University of Tennessee, Knoxville, revealed that Cooper's hawks have been observed using traffic signals as a strategic aid in their hunting endeavours within urban environments.
The study, conducted at an intersection in West Orange, New Jersey, near Dinets' home, showcases a Cooper's hawk exploiting the sound cues from pedestrian crossing signals to time its hunts more effectively. By waiting for the pedestrian signal sound, which coincides with cars stopping at the red light and people gathering or moving, the hawk would launch its attack.
The hawk would use the line of stopped cars as cover to fly low and stealthily along the sidewalk, then cross between cars to swoop down and strike prey near houses. The targeted prey were small birds such as sparrows and doves, attracted by breadcrumbs and leftovers from people dining in front yards near the traffic-lighted intersection.
Interestingly, the hawk appeared to have a good mental map of the neighbourhood and was able to recognize the sound of the pedestrian "walk" signal. It would fly from its hiding place and into a small, bushy tree when a pedestrian pressed the button, waiting for the opportune moment to pounce.
This behaviour, detailed by Dinets in an editorial for Frontiers in Ethology, highlights the bird's understanding of urban signals and its ability to adapt its hunting tactics cleverly to the city environment, making use of human-generated sound and traffic patterns to catch breakfast efficiently.
The Cooper's hawk's urban adaptability is a fascinating observation, as previous studies have only noted ravens and songbirds using cars in specific ways. This new discovery suggests that hawks may also have an understanding of urban environments and the behaviour of cars, further demonstrating their intelligence and resourcefulness in adapting to city life.
However, Dinets' observations ceased when the family who lived near the intersection moved away, and the pedestrian crossing signal stopped working. Since then, he hasn't seen any hawks exhibiting such smart hunting behaviours near his home. Nevertheless, this study underscores the remarkable abilities of urban wildlife to adapt and thrive in human-dominated environments.

- The intriguing study by Dinets published in Frontiers in Ethology reveals that Cooper's hawks exhibit a unique understanding of technology, as they use traffic signals to improve their hunting efficiency.
- This observations in urban environments, as reported by Dinets, also raises fascinating questions about the hawks' intelligence in adapting to lifestyle changes, such as home-and-garden practices, and the influence of technology on their environmental-science knowledge.
- Furthermore, Dinets' work provides insight into the potential future impact of technology on urban wildlife behavior, inspiring investigation in the intersection of science, technology, and gizmodo.
- As more studies are conducted, we might find additional examples of urban wildlife exploiting technology for survival, indicating a need for further exploration in the realm of wildlife-technology interaction.
