How do domestic pigeons typically react to an attacking raptor?

Domestic pigeons typically exhibit a specific behavior in response to different types of raptors, particularly when confronted with an accipiter, such as a Cooper's Hawk or a Sharp-shinned Hawk. Accipiters are known for their agility and propensity to hunt birds in flight, which poses a direct threat to pigeons. In this scenario, it is common for pigeons to "sky-up" or take flight to escape the predator, as their instinct is to gain altitude in an attempt to evade capture. This reflexive response highlights the pigeon's awareness of the hunting style of accipiters, which dive swiftly and can be very effective in catching smaller birds.

Other choices suggest seeking cover or ignoring the raptor entirely, which may not be accurate representations of pigeons' typical reactions. For instance, while seeking cover can be an effective strategy against certain threats, the instinctual flight response specifically stands out when encountering the more agile accipiters. Pigeons' reactions can vary based on the type of raptor, demonstrating their adaptability and survival instincts in the face of predation.
